ASA Filament 1.75mm UV Resistant Outdoor Weatherproof Tough

Brand: Yiqiu3D · Sun, rain, and summer heat destroy ordinary PLA parts within weeks, leaving them warped, yellowed, and cracked. Our ASA is a UV-stabilized, weatherproof engineering resin built for exterior-grade duty, so your outdoor enclosures, car vents, and garden sensors keep their shape and color season after season.

  • Glossy
  • Inconsistent diameter and sloppy winding cause jams and failed prints mid-job. Every spool is laser-measured for diameter consistency
  • ASA is notoriously fussy in the hands of beginners

Quick Answer

Why does ASA survive outdoors better than PLA or ABS?

ASA is built on acrylate-styrene-acrylonitrile chemistry that is inherently UV stabilized and weather resistant. Unlike PLA, it does not yellow or degrade quickly under direct sunlight, and its heat resistance keeps outdoor parts from softening, while its toughness resists cracking in wind, rain, and temperature swings. It is rated for a 220°C print temperature on this listing.

01 · Why this one

Product highlights

3 reasons

Glossy, washed-out filaments ruin the professional look of finished parts. This ASA delivers deep matte black and graphite gray with a uniform, low-glare surface that hides layer lines and photographs like injection-molded parts.

Inconsistent diameter and sloppy winding cause jams and failed prints mid-job. Every spool is laser-measured for diameter consistency, tightly wound with even tension, vacuum sealed with a desiccant pouch, and matched batch to batch for repeatable results.

ASA is notoriously fussy in the hands of beginners, yet this grade prints smoothly at the rated 220°C with reliable layer adhesion and far less odor than ABS, running cleanly on Bambu Lab, Creality, Prusa, and Anycubic machines with minimal tuning.

Frequently Asked Questions

Why does ASA survive outdoors better than PLA or ABS?
ASA is built on acrylate-styrene-acrylonitrile chemistry that is inherently UV stabilized and weather resistant. Unlike PLA, it does not yellow or degrade quickly under direct sunlight, and its heat resistance keeps outdoor parts from softening, while its toughness resists cracking in wind, rain, and temperature swings. It is rated for a 220°C print temperature on this listing.
Will this ASA filament work with my 3D printer?
Yes. This is a standard 1.75mm FDM filament, so it fits any printer with a 1.75mm hotend, including Bambu Lab, Creality, Prusa, Anycubic, and Voron machines. For the flattest, strongest results we recommend a heated bed and ideally a closed chamber, though this ASA is noticeably more forgiving than ABS.
What nozzle and bed temperatures should I use?
Start with the rated nozzle temperature of 220°C and adjust within a 220-260°C window to match your machine, then set the heated bed to 90-100°C and run the first layer slowly at 20-30 mm/s for a solid foundation. A brim is recommended for tall or large-footprint parts.
How many prints can I get from one spool?
Spool life depends on part volume and infill rather than wall-clock time. As a guide, a single spool typically yields dozens of medium functional parts such as phone mounts, brackets, or enclosures at 15-25% infill, and hundreds of small components, so the exact count varies with your slicing settings.
How consistent are the black and gray colors between batches?
Black and gray batches are color-matched during compounding, so spools bought in different orders print with the same deep, even tone. The matte formulation also reduces visible layer-to-layer shading, keeping large surfaces uniform from the first layer to the last.
What print speed range works best with this ASA?
For best layer adhesion and surface quality, print in the 40-80 mm/s range; slower speeds of 40-60 mm/s suit detailed or load-bearing parts, while up to 80 mm/s works for simple geometries. Keep outer-wall speeds slightly lower than infill to preserve dimensional accuracy.
Is ASA suitable for end-use parts or only for prototypes?
ASA is an end-use engineering material, not just a prototyping filament. Because it resists UV, moisture, and heat, it is the right choice for finished parts that live outside, such as automotive vents, drone camera mounts, mailbox hardware, greenhouse brackets, and garden light housings.
How should I store the filament and is the packaging sealed?
Each spool ships vacuum sealed with a desiccant pouch inside the bag. Store the filament in a cool, dry place and reseal the bag after opening; if it has absorbed moisture over time, dry it at around 80°C for 4 hours before printing to restore clean extrusion.
