Buying Guide – How to Choose the Best Filament for Outdoor 3D Prints
Selecting the right outdoor filament involves understanding key factors like UV resistance, heat tolerance, and print reliability. This guide breaks down the essential considerations for your next purchase.
UV Resistance
UV resistance is crucial because sunlight causes many plastics to degrade yellowing and becoming brittle over time. ASA filaments are specifically designed to resist this degradation ensuring your prints last longer outdoors.
Always check that the product description mentions UV resistance or weather resistance to guarantee long-term performance in the sun.
Heat Tolerance
Outdoor parts often face high temperatures especially when parked in direct sunlight. Look for filaments with a heat deflection temperature above 90 degrees Celsius to ensure they do not deform in heat.
Higher heat tolerance means your functional parts will maintain their shape and integrity even on hot summer days.
Dimensional Accuracy
Precise dimensions are necessary for parts that fit into assemblies or mechanical systems. Aim for filaments with tight tolerances like +/- 0.02mm for reliable and predictable results.
Good dimensional accuracy reduces the need for post-processing and ensures your printed parts fit perfectly.
Packaging Quality
Moisture can ruin filament performance leading to bubbles and weak prints. Vacuum-sealed packaging with desiccants helps keep the filament dry until you are ready to use it.
Choose brands that offer resealable or vacuum packaging to protect your investment between uses.
Color Variety
If aesthetics matter for your outdoor project, check if the filament comes in multiple colors. White and black are common but some brands offer grey or vibrant options to match your needs.
More color options give you flexibility to create projects that blend well with their surroundings.
Printer Compatibility
Ensure the filament is compatible with your specific 3D printer model and extruder system. Most ASA filaments work with standard FDM printers but some are optimized for high-speed machines.
Checking compatibility before buying helps avoid print failures and equipment issues.
Price and Value
Consider the balance between cost and performance. While budget options exist, premium filaments often offer better consistency and durability for critical outdoor projects.
Investing in a slightly more expensive filament can save money on failed prints and replacements in the long run.
Support and Warranty
Good customer support is valuable if you encounter printing issues. Look for brands that offer technical guidance or warranty for unopened spools.
Reliable support ensures you have help available if you face challenges with the printing process.
How to Use and Care for Your Filament for Outdoor 3D Prints
Before printing always ensure the filament is dry as moisture can cause bubbles and poor adhesion. If unsure dry it in a filament dryer at 70 degrees Celsius for six hours to remove any absorbed moisture.
For best results use an enclosed printer to minimize temperature fluctuations that cause warping. Set the bed temperature between 80 and 100 degrees Celsius and apply glue or tape to help parts stick.
Store unused filament in a resealable bag with desiccants or a dry box to prevent moisture absorption. Regularly check the spool for signs of moisture damage or physical defects before starting a print.
Frequently Asked Questions
Is ASA better than ABS for outdoor printing?
Yes, ASA is generally better for outdoor use because it has superior UV resistance and does not degrade or yellow as quickly as ABS. Both materials have similar heat resistance but ASA is specifically formulated to withstand sunlight.
Do I need an enclosed printer for ASA filament?
Using an enclosed printer is highly recommended for ASA filament to prevent warping caused by sudden temperature changes. Open frame printers can work but require careful tuning and draft protection for successful prints.
How should I store ASA filament to maintain quality?
Store ASA filament in a dry cool place inside vacuum-sealed or resealable bags with desiccants. Proper storage prevents moisture absorption which can lead to poor print quality and structural issues.
What is the recommended printing temperature for ASA?
The recommended nozzle temperature for ASA filament typically ranges from 240 to 270 degrees Celsius. Bed temperature should be set between 80 and 100 degrees Celsius depending on your printer and specific material brand.
Can I use ASA for mechanical parts exposed to rain?
Yes, ASA is water-resistant and durable making it suitable for mechanical parts exposed to rain and moisture. It maintains its strength and integrity even in high humidity environments when printed correctly.
Does ASA filament produce fumes during printing?
ASA filament does produce fumes during printing similar to ABS but typically less odor. Always ensure good ventilation or use a filtration system when printing ASA to protect your health and workspace.
What is the shelf life of unopened ASA filament?
Unopened ASA filament can last up to a year or more if stored in a dry environment. Vacuum-sealed packaging helps extend the shelf life by keeping moisture out until you open the spool.
Final Thoughts on Choosing the Best Filament for Outdoor 3D Prints
Choosing the right filament for outdoor 3D prints depends on your specific needs for heat resistance and durability. Our top picks include ELEGOO for overall performance iSANMATE for budget and Polymaker for premium quality.
