HIPS vs ASA
Compare HIPS and ASA filaments side-by-side. See which one is best for your 3D printing project.
HIPS
BHigh Impact Polystyrene
Impact-tolerant, low density, good for wearables/props
ASA
AAcrylonitrile Styrene Acrylate
Excellent UV resistance (outdoors indefinitely), tough, matte surface

Strengths Comparison
HIPS Strengths
- Impact-tolerant, low density, good for wearables/props
- Often used as soluble support for ASA/ABS (limonene)
ASA Strengths
- Excellent UV resistance (outdoors indefinitely), tough, matte surface
- Less warping than ABS; low viscosity enables very high speed printing
- High heat tolerance (~boiling water range)
Considerations
HIPS Caveats
- Often positioned as support material, but usable standalone
ASA Caveats
- Still off-gasses; enclosure/ventilation recommended
- Can still warp; needs tuning
Frequently Asked Questions
Is HIPS or ASA better for 3D printing?
ASA is generally rated higher (Tier A) compared to HIPS (Tier B). However, the best choice depends on your specific needs: HIPS is best for Impact-tolerant, low density, good for wearables/props, while ASA is best for Excellent UV resistance (outdoors indefinitely), tough, matte surface.
What are the temperature differences between HIPS and ASA?
HIPS prints at 220-250°C nozzle / 90-110°C bed. ASA prints at 220-275°C nozzle / 90-110°C bed.
Do HIPS and ASA need an enclosure?
HIPS: recommended. ASA: recommended.
Which is more beginner-friendly: HIPS or ASA?
Neither is particularly beginner-friendly - both typically require an enclosure.
