ASA Extrafill (Acrylic styrene acrylonitrile) is a UV resistant material with great thermal resistance used for the FFF (also known as FDM) 3D printing technology.

ASA Extrafill is a technical polymer from the same group as ABS that offers excellent work-ability, higher UV resistance, low level of yellowing and good mechanical ability. Higher rigidity than ABS makes ASA a great choice for demanding applications.

We guarantee precision dimensions of our filaments having +/- 0.05 mm tolerance, strictly controlled throughout the production.

Our filaments are produced in a wide variety of colors within the color charts RAL and Pantone. We also produce custom colors. 


ASA Extrafill is an advanced material with excellent weather resistance, retention of physical features, good dimensional stability and higher rigidity than ABS. Low level of yellowing is very important for functional applications with long-term use. To learn more about ASA see Wikipedia

ASA advantages

Parts can withstand temperatures of up to 80 °C without loosing strength
High UV resistance, low level of yellowing
Parts can be vapor smoothed for greater strength and better surface finish
Excellent weather resistance

ASA disadvantages

Requires heated bed for prints without warping


All of our filaments are designed for FFF 3D printers, which means you can expect excellent work-ability with 3D printers like Ultimaker, Prusa i3 MK2Solidoodlem, MakerBot , FlashForge, Wanhao, Leapfrog, Be3D, MAKEiT, Airwolf, 3D PrinterBot, Printerbot, Delta, Builder, Zortax, Lulzbot, UP! Plus, Up! Mini, Fusion3, Craftbot, Type A Machines, German RepRap, and a lot of more...basically if it's a 3D printer, it'll work!


We make the World's best filament and we care for it. Our newly redesigned packaging has everything to protect the filament and keep it dry.
