HIPS vs PLA
Compare HIPS and PLA filaments side-by-side so you can pick the right one for your 3D printing project.
HIPS vs PLA: HIPS is known for impact-tolerant, while PLA is known for easiest to print. PLA is easier to print; HIPS is less moisture-sensitive; HIPS prints at higher nozzle temperatures (220-250°C vs 190-220°C). Choose HIPS for impact-tolerant, or PLA for easiest to print.
Key differences at a glance
HIPS
BHigh Impact Polystyrene
Impact-tolerant, low density, good for wearables/props
PLA
APolylactic Acid
Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
Detailed Comparison
Green marks the generally easier or more forgiving option in that row, based on tier, enclosure needs, and moisture sensitivity. It is not always the better choice for a specific job, so weigh it against what your project actually needs.
Strengths Comparison
HIPS Strengths
- Impact-tolerant, low density, good for wearables/props
- Often used as soluble support for ASA/ABS (limonene)
PLA Strengths
- Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
- Stiff non-composite thermoplastic, good tensile strength
Considerations
HIPS Caveats
- Often positioned as support material, but usable standalone
PLA Caveats
- Creeps under sustained load
- Poor heat resistance, UV degradation, can shatter on drops
- Not great for sanding/gluing/painting/touch-ups
