Strengths Comparison
HIPS Strengths
- Impact-tolerant, low density, good for wearables/props
- Often used as soluble support for ASA/ABS (limonene)
TPU Strengths
- Perfect layer adhesion; extremely impact resistant; nearly indestructible
- Great for combat robots, tactical/rough-use parts
- Rubber-like parts (gaskets, grips, bumpers, wheels)
Considerations
HIPS Caveats
- Often positioned as support material, but usable standalone
TPU Caveats
- Slow printing; retraction can cause jams (especially in Bowden setups)
- Stringing is common
- Very moisture sensitive; wet TPU prints poorly
Frequently Asked Questions
Is HIPS or TPU better for 3D printing?
TPU is generally rated higher (Tier S) 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 TPU is best for Perfect layer adhesion; extremely impact resistant; nearly indestructible.
What are the temperature differences between HIPS and TPU?
HIPS prints at 220-250°C nozzle / 90-110°C bed. TPU prints at 200-240°C nozzle / 30-60°C bed.
Do HIPS and TPU need an enclosure?
HIPS: recommended. TPU: not needed.
Which is more beginner-friendly: HIPS or TPU?
TPU is more beginner-friendly as it doesn't require an enclosure.
