ASA filament
ASA is designed for parts exposed to sunlight and weather. It keeps the technical character of ABS but is better suited for outdoor use.
I'm interested →UV resistance and outdoor use.
Choose ASA when the part will be exposed to sunlight or the outdoors for a long time.
Best for
- outdoor covers and brackets
- parts exposed to UV radiation
- technical components for outdoor use
Strengths
- UV and weather resistance
- good mechanical resistance
- technical surface finish
What to consider
- requires an enclosed printer
- higher tendency to warp
- needs proper ventilation when printing
Advantages and limitations
Exact print settings may vary by printer, nozzle and part geometry. We'll send the technical data sheet (TDS) on request.

Recommended print settings for ASA
Recommended values for 3DFINITY ASA filament. Exact settings may vary by printer, nozzle and part geometry.
| Parameter | Recommended value |
|---|---|
| Nozzle temperature | 250–270 °C |
| Bed temperature | 95–115 °C |
| Print speed | 25–180 mm/s |
| Enclosed chamber | Yes, recommended, draft-free; if heated, 50–60 °C |
| Part cooling | 0–10% |
| Filament drying | 65 °C / 4–6 h if needed |
| Material density | approx. 1.07 g/cm³ |
Recommended nozzle
| Nozzle | Nozzle diameter |
|---|---|
| standard | 0.2 / 0.4 / 0.6 / 0.8 mm |
Starting point setting (a first point to test)
| Nozzle | Bed | Speed | Part cooling |
|---|---|---|---|
| 260 °C | 115 °C | 50 mm/s | 0% |
Printing tips
Preheat the bed and chamber, add a 5–10 mm brim for larger parts and protect them from draughts. After printing, let the part cool gradually in the chamber and ventilate the workspace. If corners lift, adjust adhesion and preheating first. Small parts and overhangs may need slight cooling.
These values are indicative, for a 0.20 mm layer height and a 0.4 mm nozzle (0.6 mm for CF and GF). Start with the baseline setting and fine-tune it for your printer — maximum speed can be limited by hotend flow rate. The cooling fan value in the table refers to the part-cooling fan; print the first 2 layers without cooling, overhangs and bridges may need more. Leave the hotend cooling fan at your printer manufacturer's default setting. Dry the filament in a temperature-controlled dryer, don't exceed the spool's heat resistance, and after drying store it sealed with a desiccant.

Questions about ASA
What is ASA filament suitable for?
ASA is designed for parts exposed to sunlight and weather. It keeps the technical character of ABS but is better suited for outdoor use.
Is ASA suitable for outdoor use?
Yes. ASA is UV- and weather-resistant, which also makes it suitable for parts used outdoors for extended periods.
What diameter and tolerance does 3DFINITY ASA filament have?
ASA filament is manufactured at a 1.75 mm diameter with a declared tolerance of ±0.05 mm. We make it using our own technology in Slovakia with diameter control during production.
