ASA Filament(Acrylonitrile Styrene Acrylate)

VOXFIL ASA keeps ABS-level mechanical performance while resisting UV degradation and weathering far better. Outdoor enclosures, drone parts and automotive exterior components keep their color and strength in direct sunlight for years.

ASA filament keeps all the strength of ABS but adds serious UV and weather resistance — outdoor enclosures, drone parts and automotive exterior components hold their color and properties for years in direct sun.

How to printASA

Recommended starting profile, proven on open printers and enclosed systems alike.

Nozzle

240 – 260 °C (250 °C sweet spot)

Bed

95 – 110 °C, enclosure required

Speed

40 – 80 mm/s, cooling off

Prints like ABS but holds color in the sun

Do's & don'ts

Print ASA the right way

✓ Do

  • Keep the enclosure closed — ASA loves stable heat
  • Dry at 85 °C for 4 h before long outdoor prints

✗ Don't

  • Expose spools to humidity before printing
  • Push cooling above 20% on tall parts — layer bond suffers

What volume buyers say

★★★★★

“We run 40 printers 24/7 and switched our farm to VOXFIL PETG and PLA+. Batch-to-batch consistency is the best we've seen from any Asian supplier — color matching is spot on every time.”

Marcus R.Print Farm Owner, Germany
★★★★★

“As a distributor we needed a partner who could private label without drama. VOXFIL delivered custom colors, our packaging and perfect QC reports. Our returns dropped to near zero.”

Sofia L.Filament Distributor, Spain
★★★★★

“Our university labs buy 1,000+ spools a year. The ±0.02 mm tolerance and honest datasheets mean fewer failed prints and happier students.”

FAQ

ASA filament —common questions

ASA has nearly identical mechanical properties to ABS but resists UV degradation and weathering far better, making it the right choice for outdoor and automotive parts.
Yes, like ABS, print ASA inside a heated enclosure with the cooling fan off or minimal for best layer adhesion.
Nozzle 240–260 °C, bed 95–110 °C. Dry at 85 °C for 4 h before long prints.
Yes — ASA is available in 1 kg, 3 kg and 5 kg spools, in custom colors and with private label from 100 kg. MOQ for custom colors starts at 10 kg, and samples ship in 72 hours.
Sealed bag, below 40% RH
All VOXFIL materials are standard 1.75 mm and work with Bambu Lab, Prusa, Creality, Voron and other open printers. Free starting profiles are provided for Bambu Studio, PrusaSlicer, Cura and OrcaSlicer.
