ASA filament print tips

ASA 3D printer filament

ASA (Acrylic Styrene Acrylonitrile) is a 3D printable plastic. ASA filament is similar in properties to ABS. It has been developed as a UV resistant version of ABS. In addition to UV and weather resistance, ASA is also known for its high impact strength and high temperature resistance.

Advantages

UV and weather resistant.

High impact strength and wear resistance.

High glass transition temperature.

Cons

Pricey.

High extruder temperature required.

Filter needed due to vapours.

Hardware requirements.

Before you order ASA filament. It is advisable to check whether your 3D printer has the correct hardware. So that you too can achieve optimum print quality with ASA.

Bed

Heated bed is needed.

Temperature: 90-110°C

Closed printer is not necessary per se.

Construction area

Kapton tape
PET Sheets
ABS/ASA Slurry

extruder

Temperature: 220-245°C
No special hotend needed.

cooling

Fan not required.

Pro Tips.

A mixture of ABS or ASA and acetone on your heated print bed provides a good adhesive layer.

ASA can be smoothed out by controlled exposure to acetone vapors.

You can use HIPS as a support filament.

Avoid problems when printing.

With the tips you can reduce the most common problems when printing with ASA. Such as warping, shrinking and poor adhesion to the print bed.

Invest in a good building surface.

For best layer adhesion, we recommend using Buildtak or Kapton tape on your heated bed. Please note that this increases your building surface a little bit. So we advise to “level” the bed again. By using an adhesive such as Buildtak you will improve first coat adhesion and reduce warping.

The right temperature and cooling settings.

ASA is printed at a fairly high temperature. Therefore, make sure that you cool well to prevent overheating of the parts. Because lowering the temperature during printing can help. Due to the high temperature, the first layers will adhere well to the bed. You can then lower the temperature by 5°C 1 or 2 times. This means that you do not suffer from overheating at the end of your print.
