ASA is a styrenic polymer that is ideal for the production of the first functional samples before serial production for functional prototyping, manufacturing tools, but also for the production of goods for everyday usage, especially for outdoor applications. It can withstand high long-term heat exposure and exposure to UV light.


  • Low levels of yellowing
  • Excellent weather and UV light resistance
  • Retention of physical features such as color and mechanical properties
  • Low moisture absorption
  • Impact resistance
  • Higher resilience than ABS
  • Recyclable
  • Chemical resistance against alkalis, alcohols, oils, greases, ozone, and water
  • Long-term dimensional stability
  • Low density
  • Safe to use in electrical and electronic equipment

My first print with ASA

So I expect troubles during printing and for this reason I did some fence around my printer and did first print part. What was my surprise that not so easy part with some small support was simply excelent! First shot and perfect.
I can fully reccomand this brand because it simply works. Also I very appriciate aproache from company, because for picking up my order I was late, but from Mr. Vladimir Barton comes favor and he wait for me and gave me my order out of working hours. That was for me really big pleasure and it is also 50% of product as well. Realy can reccomand to anybody this brand. From my side just simple THANKS A LOT and wish to all company all the best in year 2024
Thank you...
