What can you make with a 3D printer? 

Let’s examine three practical examples showcasing the versatility of 3D printing:

Custom 3D Printed Card Box

3D printing offers trading card game enthusiasts convenient customization for their cherished collections. 3D printed deck boxes provide individualized dimensions because they differ from the standardized storage products that exist in markets today.

• Perfect sizing for your collection: Whether you’re storing a standard 60-card MTG deck, a 100-card Commander deck, or any TCG format (like Pokémon, Yu-Gi-Oh!, or Lorcana), you can design boxes with precise internal dimensions.
• Sleeve-friendly design: The design of these storage units allows you to fit single—to triple-sleeved cards while maintaining protective clearance space for easy access.
• Personalized compartments: Create dedicated spaces for tokens, counters, dice, or sideboard cards—all contained within a single storage solution.
• Special aesthetic touches: You can add game logos, character designs, or personal emblems directly into the box structure for your collection.
• Cost-effective alternative: Custom 3D printed storage solutions use only a few dollars for filament. The final product costs less than a premium commercial box. Established brands sell boxes that start at $30 and can go up to $50 per unit. 

It might surprise you how much planning goes into sizing these boxes—considering card dimensions (with and without sleeves), deck thickness, and even leaving extra space for easier access. This level of customization simply isn’t available in commercial options. Here is our detailed guide—3D Printed Deck Box Guide for TCG Players.

Adjustable Smartphone Photography Rig

3D printing enables photographers and content creators to design specialized equipment at a fraction of commercial costs. The smartphone photography rig showcases this perfectly.

• Precision photography setup: Create a repeatable way to photograph small objects (like 3DBenchy models) at consistent, fixed angles—essential for documenting your 3D printing journey or product photography.
• Customizable fixtures: Design includes a rotary platform for capturing seamless 360° videos, sliding fixture holders to adjust object-to-camera distance, and adaptable mounts for various smartphone models.
• Professional lighting solutions: Incorporate universal holders for flashlights and light bouncers to achieve professional-quality lighting without expensive equipment.
• Adaptable for various subjects: While initially designed for 3DBenchy models, the rig works perfectly for photographing other small objects like stamps, insects, flowers, miniatures, and toy figurines.

This project is particularly valuable because all components can be printed within common build volumes, making it accessible to most 3D printer owners. The capability to produce professional-grade photography equipment tailored to your specific needs illustrates how 3D printing connects the divide between consumer-grade and professional tools.

Workshop Fixtures and CNC Workholding Solutions

3D printing transforms how makers approach their workshop organization and machining tasks. Custom fixtures such as the Snapmaker clamps highlight the practical benefits of this technology.

• Custom CNC workholding: Design and print specialized clamps, vises, and fixtures that perfectly secure workpieces during CNC operations, ensuring precision cuts and consistent results.
• Project-specific jigs: Create assembly jigs that precisely align components during construction, bonding jigs that maintain pressure during adhesive curing, and inspection fixtures for quality control.
• Cost-effective workshop solutions: Replace expensive commercial fixtures with custom-designed alternatives that use minimal material (typically just a few dollars worth of filament plus basic hardware like M4 threaded rods and wing nuts).
• Rapid implementation: Move from identifying a workshop need to having a functional solution in hours instead of days or weeks—design, print, test, and refine all in the same day.
• Optimized workflow integration: Design fixtures specifically for your unique tools, workspaces, and projects rather than adapting your work to fit standard commercial options.

The beauty of 3D printed workshop fixtures lies in their adaptability. Unlike commercial options that serve general purposes, your 3D printed fixtures can incorporate specialized features like integrated cooling channels, ergonomic handling surfaces, and weight-reducing internal structures. They represent a perfect marriage between digital design freedom and practical workshop application, making your CNC and manual operations more efficient, precise, and enjoyable.

Tips for Creating Useful 3D Prints

Material Matters

When creating functional 3D prints, material selection directly impacts durability, functionality, and appearance. 

• PLA: Easy to print and ideal for prototyping, but less suitable for items needing strength or heat resistance
• PETG: Excellent balance of strength, flexibility, and ease of printing. For TCG deck boxes, PETG provides the perfect combination of durability and printing ease. Its slight flexibility prevents cracking while protecting valuable cards.
• ABS: Superior heat resistance and durability. Workshop fixtures and CNC clamps benefit from ABS’s higher temperature resistance and strength.
• Nylon: For parts requiring exceptional strength and flexibility like mechanical components.

Synergy: 3D Printing and CNC Carving

For maximum workshop versatility, consider combining 3D printing with CNC carving—these complementary technologies create a complete fabrication ecosystem. From a certain perspective, 3D printers themselves are a form of CNC machine, just working additively rather than subtractively. If this idea sparks your interest, you can find further discussion on History of CNC Machines: From Punch Cards to Your Desktop.

• Prototype before commitment: 3D print complex models to verify fit and function before machining expensive materials like hardwood or aluminum
• Create specialized tooling: Design and print custom fixtures, soft jaws, and work-holding solutions specifically for your CNC projects
• Develop perfect models: A complex decorative piece might require 4+ test prints before achieving the perfect design for final CNC production

Multi-function machines like the Artisan 3-in-1 provide both technologies in a single footprint, making this approach accessible even in space-constrained workshops.

Master CAD

While downloading pre-made models from repositories like Thingiverse or Printables is convenient, the true magic of 3D printing emerges when you create custom designs that perfectly address your specific needs. Learning Computer-Aided Design (CAD) transforms your 3D printer from a reproduction tool into a personal manufacturing solution.

The learning curve might seem steep, but start with simple projects—perhaps a basic phone stand or a custom spacer for your workshop. As your skills develop, you’ll naturally progress to more complex designs like articulated fixtures or precisely-fitted deck boxes.

Many beginner-friendly CAD programs offer intuitive interfaces with abundant tutorials. The investment in learning these skills pays dividends across all your projects, allowing you to iterate designs quickly and solve unique problems that no downloadable model can address.

From Numerical Control to the First CNC Machine

The backbone of any desktop CNC is actually founded on Numerical Control (NC). But what does CNC stand for? It stands for Computerized Numerical Control, which, to begin with, developed from the need for more precision in manufacturing and more automation in the manufacturing of intricate parts, especially from the aerospace industries. All of these factors were taken into account in the development process of NC in the late 1940s and early 1950s.

The conventional, accepted “first” CNC machine was, however, a hydro-mechanical milling machine built at the Massachusetts Institute of Technology during the late 1940s and early 1950s under a contract from the US Air Force. John T. Parsons led the project, recognizing the possibility of punched cards being used to input coordinate data for controlling the movements of a machine tool.

To put it in the simplest terms:

• The problem with manufacturing involves very complex three-dimensional aircraft parts (as with the rotor blades of helicopters) needing to be produced with accuracy, and this type of work was also often laborious and erratic by manual methods.
• Parsons’ concept: He thought of putting a system in place under which numerical data punched on cards would control the movement of the machine.
• MIT Collaboration: Parsons worked with MIT’s Servomechanisms Laboratory to develop this notion.
• The First CNC Machine: This resulted in a modified milling machine that directed the movement of servomotors connected with signals read from punched cards along three axes, defining the position of the cutting tool. This demonstrated the feasibility of computer-controlled machining.

While this groundbreaking machine was not a computer in the modern sense, it laid the groundwork for Computer Numerical Control. The “computer” aspect came later with the integrating of actual computers into the control systems.

The Birth of CNC

The true revolution came with the integration of computers into the control systems. The first step was crossing from NC to Computer Numerical Control (CNC). Very huge, expensive, and mainly used within large industrial installations were the early CNC machines, when one thought of a “CNC machine”; it conjured images of great, gigantic milling machines and lathes in factories.

The Rise of Desktop CNC

It was not until decades later that the dream of CNC coming into the small shop, school, or even home became a reality. Several developments in technology paved the way for desktop CNC machines:

• Miniaturization of Computing, as smaller, more powerful, and less expensive computers came along, making it feasible to include them in smaller machine tools.
• Microcontroller Revolution: All machine tools have spread low-cost and compact control systems with the introduction of microcontrollers.
• Better motor technology: Smaller, more precise stepper and servo motors enabled accurate control of movement in smaller form factors. 
• The Maker Movement: There is growing interest in personal fabrication and DIY businesses, fueling demand for widely available CNC tools.

Key Moments in Desktop CNC History

• Late 20th Century
• Early 2000s
• Mid to Late 2000s
• 2010s and Beyond

Towards the end of the 20th century: Early in the 21st century, small kit-type CNC machines started pouring in for hobbyists and educational purposes. Such machines were often the poor cousins of machines in the industrial setting. “CNC” would be a largely industrialized concept.

Into the early 2000s: The propagation of open source, through RepRap and other projects, was a defining element in opening up CNC technology: Although RepRap was about 3D printing, its principles of open-source hardware and software were applied to low-cost control systems for other kinds of CNC machines, thereby doing much to popularize CNC. The association of “CNC” with anything that wasn’t a subtractive tool began.

More likely Mid to Late 2000s: This change saw desktop CNC routers hitting the market at reasonable prices with desktop CNC mills becoming even better affordable. These soon enabled the maker, and small business, to dabble in wood, plastics, and even light metals. The whole language now saw evolution, where “desktop” was prefixed to create a distinction between these smaller machines.

2010s and Beyond: The market for desktop CNC machines truly exploded. Desktop CNC laser cutters bring forth fine cutting and engraving. Importantly, desktop CNC 3D printers also get their fair share of falling prices. The understanding of “CNC machine” hence becomes very broad: not only machining, but also additive methods can fall into the same definition. New terminologies began to arise, giving rise to common terms such as CNC router, CNC mill, CNC laser cutter, and CNC 3D printer. 

The latest era also saw the emergence of versatile machines like the Artisan 3-in-1, which integrates 3D printing, laser engraving/cutting, and powerful CNC machining into a single unit. The Artisan comes standard with a robust 200W CNC module that machines challenging materials, including beech, walnut, and jade.

Types of Desktop CNC Machines

• Desktop CNC Routers: Ideal for carving, cutting, and shaping wood, plastics, and composites. They represent a continuation of the traditional subtractive CNC concept in a smaller form factor.
• Desktop CNC Mills: capable of removing material on metals and tougher plastics with absolute precision at a smaller scale so as to bring industrial milling capabilities at a very small scale. 
• Desktop CNC Laser Cutters: Offer cutting and engraving capabilities on a wide range of substrates with precision cuts and engravings using a focused laser beam. This introduced a different method of material removal under CNC. 
• Desktop CNC 3D Printers: As discussed earlier, these additive machines build objects layer by layer from digital designs. Their inclusion significantly expanded the definition of a “CNC machine” to include additive processes.

Furthermore, the capabilities of desktop CNC machining can be expanded with the addition of a rotary module. For Artisan 3-in-1, the rotary module upgrades the standard 3-axis CNC to a 4-axis system, enabling 360° rotation of the workpiece. This allows the creation of intricate three-dimensional shapes that are difficult to achieve with a standard 3-axis setup.

As the types of CNC machines have diversified, so has our language around them. Initially, “CNC machine” almost exclusively referred to large, subtractive tools. However, with the advent of desktop versions and the rise of additive manufacturing, we now commonly use more specific terms to avoid ambiguity. The prefix “desktop” clearly indicates a smaller, more accessible machine. Furthermore, specifying the type of process (routing, milling, laser cutting, 3D printing) provides a clearer understanding of the machine’s function.

Conclusion

By deepening into the history of CNC machines, we get to know the marvelous journey of invention and to discover CNC technology for itself, it is not just the processing of materials but how it is also applied in other sectors like aerospace, automotive, and healthcare in the endeavor to bring quality and innovation in the development of products.

How to Recycle 3D Printer Filaments

So, how can we turn those piles of plastic into something useful again? There are a few key approaches:

DIY Filament Extruder

For the truly dedicated maker aiming for a circular workflow, creating a DIY filament extruder line is the ultimate goal. This involves transforming your plastic waste directly back into printable filament.

The process requires:

• Sorting: Separate plastics by type (PLA, PETG, etc.) as mixing causes material failures
• Cleaning: Remove all glue, dirt, and contaminants
• Shredding: Break down failed prints and support structures into uniform flakes
• Drying: Remove moisture (typically in a low-temperature oven) to prevent bubble formation
• Extrusion: Feed dried flakes into a desktop extruder where they melt and pass through a precision nozzle
• Cooling and Measuring: Maintain consistent diameter (1.75mm or 2.85mm) using sensors and feedback systems
• Spooling: Wind the cooled filament onto a spool for future use

The process involves mechanical challenges: inconsistent diameters, extruder jams, and unpredictable color blending. It requires significant hardware investment (shredder, dryer, extruder, winder) and understanding of polymer properties.

Mold Casting: Direct Repurposing

A more accessible alternative to filament extrusion is melting scraps for casting into new objects.

• Collection and Sorting: Group plastics by type. Different plastics (PLA, PETG, ABS, etc.) melt at varying temperatures and do not mix well. Sorting plastic types by color is advisable, as this allows you to plan for desired visual effects like swirls or specific color blocks. 
• Melting: Heat plastic (PLA is preferred at around 180°C) in a dedicated toaster oven designated solely for melting plastics. This helps prevent toxic residues from contaminating food surfaces. Remember to ensure good ventilation to avoid accumulating VOCs. 
• Molding: Carefully pour the thoroughly melted plastic into heat-resistant molds; silicone molds are often ideal due to their flexibility which aids in easy demolding, but clean metal tins or custom-made molds can also be used. Ensure your chosen mold is clean and dry before pouring.
• Cooling and Finishing: Allow the plastic to cool completely within the mold, noting that cooling time will vary significantly depending on the size and thickness of the object. Once fully solidified, you can remove the item, and minor finishing like trimming or sanding rough edges might be needed for a clean look.

This method produces distinctive objects with marbled or terrazzo-like patterns. Common applications include buttons, coasters, pendants, decorative tiles, and small figurines.

For more advanced projects, versatile multi-function machines like the Artisan 3-in-1 offer significant advantages. Using its CNC milling capabilities, you can create precise negative master molds from wood or acrylic. A practical approach often involves using this master to cast a durable, heat-resistant silicone rubber mold, which captures fine details effectively and withstands repeated use with hot plastic. Simultaneously, its laser cutting function allows for adding intricate pattern designs to your molds or parts. This combination is particularly effective for crafting batches of custom buttons from sorted PLA waste—simply design your button, CNC a mold master, cast your silicone production mold, then melt and pour your PLA scraps. 

The process requires less technical equipment than filament extrusion, focusing on creative expression rather than precision manufacturing.

Empty Spool Repurposing

What to do with old 3D printer filament spools? The plastic or cardboard spools that hold filament offer additional recycling opportunities:

• Can be converted into storage solutions
• Used as bases for painting projects
• Incorporated into planters
• Repurposed as structural elements for toys or sculptures

Notable examples include converting spools into Ferris wheel garages for toy cars and creating modular organizational systems.

Is It Worth It to Recycle Filament? 

Given the effort involved, especially with DIY extrusion, is it truly worthwhile? The value proposition of filament recycling could be examined from multiple angles:

Environmental Impact

Recycling definitively reduces plastic waste headed to landfills or incineration, representing a significant step toward making 3D printing more sustainable. Learn more in The Environmental Impact of 3D Printing: Is It Sustainable?

Cost-Effectiveness

The economics are nuanced:

• DIY extrusion promises long-term material cost savings but requires substantial initial equipment investment
• Time requirements for processing can be significant
• Energy consumption for shredding, drying, and melting adds to operational costs
• Small-scale hobbyists may not find it economically viable unless viewed as part of a learning process or long-term commitment
• Melting and casting methods offer much lower financial barriers to entry

Community Collaboration

This approach maximizes recycling benefits:

• Equipment for efficient shredding and extrusion is ideal for community use
• Makerspaces, schools, and local 3D printing clubs can pool resources
• Shared equipment makes high-quality recycling accessible and cost-effective
• Collective scraps and knowledge exchange enhance collaboration

Learning & Innovation

Beyond practical considerations, the process itself delivers value by fostering hands-on learning about:

• Materials science
• Engineering principles
• Problem-solving challenges
• Core maker skills and mindset

The recycling journey often extends beyond simple cost calculations to encompass broader benefits to makers and their communities.

Final Words

Filament recycling represents a promising frontier in the 3D printing ecosystem. Whether you choose to:

• Build a complete extrusion system
• Repurpose plastic through melting and casting
• Join community recycling efforts

Each approach contributes to sustainable making practices and reduces waste. DIY recycling methods require adaptation to your specific materials and equipment. Start with methods that match your resources and goals, then expand your capabilities as your experience grows.

This guide will introduce the properties of various FDM 3D printing filaments, from everyday plastics to specialized materials.

What Types of 3D Printer Filaments Are There? 

The accessibility and improving print quality of FDM 3D printers have fueled a growing demand for filaments. Let’s look into the details of popular choices:

PLA (Polylactic Acid)

• Ease of Printing: Very Easy. Often considered the easiest to print, requiring lower temperatures and generally forgiving with printer settings. It’s less prone to warping than most other common filaments.
• Strength: Moderate. Good for general-purpose prints and prototypes, but not as strong as ABS or PETG.
• Flexibility: Low. Typically quite rigid and can be brittle.
• Durability: Medium. Suitable for indoor use and decorative items, but can degrade with prolonged UV exposure or high temperatures.
• Temperature Resistance: Low (around 50-60°C / 122-140°F). Not ideal for parts that will be exposed to significant heat.
• Typical Applications: Prototyping, educational projects, decorative items (vases, figurines), tools that won’t experience high stress or temperature.

You can find high-quality PLA filament in the Snapmaker Store.

ABS (Acrylonitrile Butadiene Styrene)

• Ease of Printing: Medium to Difficult. More challenging than PLA due to its tendency to warp, especially with larger prints. Requires a heated bed and often an enclosure to maintain a consistent temperature.
• Strength: Good. Stronger and more impact-resistant than PLA.
• Flexibility: Medium. Offers a bit more flexibility than PLA but is still relatively rigid.
• Durability: High. Good for functional parts that need to withstand wear and tear.
• Temperature Resistance: Medium (around 80-100°C / 176-212°F). Higher than PLA, making it suitable for some warmer environments.
• Typical Applications: Functional prototypes, mechanical parts (gears, clips), enclosures, toys, items that need to be durable and heat-resistant (within its limits).

You can find high-quality ABS filament in the Snapmaker Store.

What is the Best Filament for 3D Printing?

There’s no single “best” filament – the ideal choice depends entirely on your specific purpose. 

To choose the right filament, first ask yourself: What will the object be used for? Is it a decorative item, functional part, prototype, tool, or something for outdoor use? Then decide on the required properties:

• Strength and Durability: For objects needing to withstand stress or repeated use, choose ABS, PETG, Nylon, or Polycarbonate.
• Flexibility: For objects requiring bending or acting as seals, use TPU or TPE. Flexible PLA offers a milder flexibility.
• Temperature Resistance: For heat-exposed objects, select ABS, PETG, ASA, Nylon, or Polycarbonate. Avoid PLA in high-temperature environments.
• Special Considerations: Consider chemical resistance, water resistance, food safety, and UV resistance based on your specific application.

Next, consider the capabilities of your printer:

• Nozzle temperature limits
• Presence of a heated bed
• Printer enclosure
• Extruder type
• Nozzle material (especially for abrasive filaments)

Final Words

While dedicated filament manufacturers offer a wider variety, 3D printer companies often provide a more “plug-and-play” experience with filaments optimized for their machines. Also note that even for the same nominal type of filament (like standard PLA), the exact chemical formulation can vary between different brands, impacting print quality and material properties.

Snapmaker is going to release a batch of new filaments around June, so stay tuned for more exciting material options!

Most Common Causes of 3D Print Warping

The reason why parts of a 3D print warp is their uneven cooling. The plastic, as it cools, contracts. If the lower layers cool and contract when the upper layers are still warm, the internal stress can make it lift or warp, particularly around the corners. It must be noted, however, that the thermal contraction and expansion depend on the filament type.

Let’s dive slightly deeper into each of the causes of warping.

Bed Adhesion Issues

• Uneven bed leveling: An unleveled bed leads to inconsistent first layer adhesion, making the print more susceptible to warping. 
• Dirty or oily build plate: Contaminants on the build plate can prevent the filament from sticking properly, leading to lifting and warping. 
• Inappropriate bed surface material: Different materials adhere better to different build surfaces. 

Temperature Problems

• Inconsistent bed temperature: The heated bed should remain at a consistent temperature to prevent warping. If the bed is too cold, the print might warp or detach.
• Drafts and ambient temperature fluctuations: Fluctuations in room temperature can lead to warping, especially for temperature-sensitive materials like ABS. 
• Incorrect nozzle temperature: While primarily affecting extrusion, incorrect nozzle temperature can indirectly contribute to warping by affecting layer adhesion.

Print Settings

• Insufficient or incorrect first layer settings: The first layer is the foundation. An incorrect nozzle distance or printing too fast can lead to poor adhesion and subsequent warping.
• Lack of brim or raft: Brims and rafts increase the surface area in contact with the build plate, improving adhesion and helping to prevent corners from lifting.
• Infill patterns and density: While not a primary driver of warping, using very high infill densities or certain infill patterns that cause significant internal stress during cooling could potentially contribute to the issue.

How to Prevent 3D Print Warping 

Having understood the reasons behind the warping of 3D printing, it is time to look at practical steps that can be taken to prevent it and have the prints well-bedroomed on the build plate.

Optimizing Bed Adhesion

• Thorough bed leveling techniques. This involves ensuring the nozzle is the same distance from the bed at all points. Many modern printers have auto-leveling, and the Snapmaker does. For manual leveling, a piece of paper can be used to gauge the correct distance.

• Cleaning the build plate effectively. Cleaning the bed with isopropyl alcohol before each print to remove any oils or debris.
• Choosing the right bed surface.
  • Glass beds can provide a very smooth and flat surface, often requiring adhesion aids for good grip.
  • PEI (Polyetherimide) sheets offer excellent adhesion for a wide range of materials, especially when heated. Textured PEI often works well for PLA, PETG, and ABS. However, printing highly adhesive filaments like PETG and TPU on the smooth PEI plate is not recommended.
  • Painter’s tape is a cost-effective option, particularly for PLA. Apply it smoothly to your build plate, ensuring no air bubbles.
• Using adhesion aids. These can provide an extra layer of adhesion, especially for materials prone to warping.
  • Glue sticks (PVA-based) can create a slightly tacky surface that helps the first layer stick. Apply a thin, even layer to the build plate.
  • Hairspray can also provide a sticky surface. Apply a light, even coat to the build plate before heating.

Controlling Temperature

• Maintaining a consistent bed temperature: Use your slicing software to set the recommended bed temperature for your filament. Ensure your printer’s bed heating element is functioning correctly and maintaining a stable temperature throughout the print.
• Enclosing your 3D printer: For materials like ABS that are highly susceptible to warping due to temperature fluctuations, an enclosure is highly recommended. This helps to trap heat, creating a more stable ambient temperature around the print and preventing drafts. You can purchase purpose-built enclosures or even create your own DIY version.

• Adjusting ambient temperature if necessary: Try to print in a room where the temperature is relatively stable and within the recommended range for your filament (e.g., 20-25°C for PLA). Avoid placing your printer near open windows or air conditioning vents.

Slicing Software Settings

• Optimizing first layer height and width: Setting the initial layer height slightly higher than subsequent layers can improve adhesion by ensuring more contact with the build plate. Similarly, increasing the first layer width can also enhance adhesion.
• Utilizing brims and rafts effectively:
  • Brims are excellent for preventing corners from lifting on parts with a large, flat base. They are relatively easy to remove after printing.
  • Rafts provide a completely separate foundation for your print, which can be particularly useful for complex geometries or when printing materials known to warp. However, they do use more filament and require removal.
• Experimenting with different infill patterns: While not a direct fix for warping, try using infill patterns that might introduce less stress during cooling, such as rectilinear or gyroid. Lowering the infill density for the initial layers might also be worth experimenting with.

Fixing PLA Warping & ABS Warping

PLA is generally easier to print but can still warp, especially in larger prints, due to cooling and contraction. ABS is more prone to warping due to its higher printing temperature and greater thermal contraction.

• At what temperature does PLA warp? PLA can start to lose form above its glass transition temperature, which is around 60°C. While it won’t melt until 150-160°C, maintaining a bed temperature within the recommended range (often 25-60°C) is crucial to prevent warping
• How do I keep my PLA prints from warping so big? PLA larger prints need excellent bed adhesion (such as a textured PEI sheet), a consistent bed temperature (use cooling fans appropriately to prevent excessive heat buildup), and potentially using a brim or raft. 
• At what temperature does ABS bend? ABS bends when heated past its glass transition temperature, which is around 101°C. To avoid warping, a bed temperature range of 80˚C–100˚C is recommended.
• How to keep large ABS prints from warping? Printing large ABS effectively requires a heated bed (around 100°C) and an enclosure to maintain a stable temperature and prevent drafts. 

Conclusion

Warping is a condition that most people hate and unpleasant in 3D printing. This occurs due to uneven cooling resulting in contraction and deformation of some materials. Improper bed adhesion, mismatched temperature readings, and wrong setting configurations will cause prints to lift off the bed or even cause warping on the corners of the print.

Various improvements to adhesion, fine-tuning the conditions of the environment during printing, and altering slicing settings could help to minimize print warping and advance their quality. Also, minor changes like leveling the bed, using adhesion agents, and encasing your printer could make a huge difference, especially when dealing with things like ABS and PLA.

This guide will clarify both specifications, focusing on the essential importance of filament diameter and the more practical considerations of spool dimensions.

Understanding Filament Diameter: 1.75 mm vs. 2.85 mm

It is the thickness of the plastic string that your 3D printer melts and extrudes to build your 3D printed object. It is typically expressed in millimeters (mm). This measurement is critical because 3D printers are designed to work with a specific filament diameter, and using the correct size ensures proper feeding and extrusion during the printing process.

Filament comes in two main diameters. 

• 1.75 mm: This is the popular choice for desktop 3D printers, compatible with a wide range of materials. It offers a good balance of detail and potentially faster speeds. While excellent for intricate prints, it can be slightly more prone to buckling in some Bowden setups.
• 2.85 mm (or sometimes called 3 mm): This is less common for desktop printers but is still used, particularly in some older or industrial-style machines. It offers robustness and can be easily handled, particularly with flexible filaments. However, it generally provides less detail and may have fewer material options.

Is a 1.75 or 2.85 filament better? Neither is definitively “better” overall. However, 1.75mm filament is generally the preferred choice for most users. It’s more versatile, widely supported, and capable of excellent print quality. Unless you have a specific need for 2.85mm, such as primarily printing very soft, flexible materials or if your printer is specifically designed for it, 1.75mm filament is usually the better all-around option. 

Does filament diameter matter?

Filament diameter directly impacts the quality and success of the print. Using the wrong diameter filament is a recipe for printing failures and potential printer damage:

Printer Compatibility

This is the most critical dimension for printer compatibility. 3D printers are designed to work with a specific filament diameter. If you use the wrong diameter, it can lead to serious problems:

• Clogging: Using too thick filament for your printer’s hot end and nozzle can cause jams and blockages.
• Extrusion Issues: Using too thin filament can cause inconsistent extrusion, under-extrusion (not enough plastic being pushed out), and poor print quality.
• Damage to Extruder: Forcing the wrong diameter filament can potentially damage the extruder mechanism.

Print Quality

The filament diameter is directly related to the precision and detail your printer can achieve.

• Detail: 1.75 mm filament is favored for finer details due to its responsiveness. 2.85 mm can be less precise for intricate designs.
• Flexibility: 1.75 mm filament’s flexibility aids in intricate prints but can be slightly more prone to buckling in Bowden systems. 2.85 mm’s stiffness can be advantageous for very flexible materials.
• Speed & Flow: 1.75 mm filament may achieve higher volumetric flow rates, potentially enabling faster printing.

3D Printer Filament Spool Dimensions

What are the dimensions of a spool of filament? Beyond filament diameter, spool dimensions are also important for physical compatibility with your 3D printer. While not standardized, spools generally adhere to common sizes, especially for standard 1kg spools.

Common Dimensions for 1kg Spools:

• Outer Diameter (Flange Diameter): Around 200mm (7.87″ – 7.93″). Needs to fit within your 3D printer’s spool holder or enclosure.
• Inner Diameter (Arbor Hole or Center Inside Diameter): Roughly 52mm – 58mm (2.05″ – 2.28″). This is the size of the hole in the center of the spool. It needs to be compatible with your printer’s spool holder arm or spindle. 52mm is a very common inner diameter.
• Spool Depth (Outside Width): Approximately 50mm – 70mm (2″ – 2.75″). The spool needs to fit in the width of your printer’s spool holder.

Key Considerations for Spool Dimensions:

• Physical Fit: Ensure the spool’s outer diameter and width are compatible with your printer’s spool holder.
• Smooth Unwinding: Standard spool dimensions promote smooth filament unwinding during printing.
• Accessory Compatibility: When considering spool dimensions, it’s also worth noting accessories that can enhance your 3D printing workflow. For example, the Snapmaker SnapDryer is a filament dryer that works with both 1.75mm and 2.85mm filament diameters. It’s built to accommodate spools up to 205 mm in diameter and 78 mm in thickness. This compatibility with standard spool sizes makes it versatile for most users, but also illustrates why dimensions matter when investing in specialized equipment.

Takeaways

• Filament Diameter (1.75 mm or 2.85 mm) = Thickness of the plastic string. This is crucial for your printer’s extrusion settings.
• Spool Diameter (around 200 mm) = Size of the reel that holds the filament. This is crucial for physical compatibility with your printer’s spool holder.
• Always buy the correct filament diameter (1.75 mm or 2.85 mm) specified for your 3D printer. Double-check your printer’s manual and filament packaging.
• For spool diameter, generally, standard 1kg spools will work with most desktop printers. Be more mindful of spool dimensions if you are using very large or unusual spools.
