High-speed PLA vs TPU
Compare High-speed PLA and TPU filaments side-by-side. See which one is best for your 3D printing project.
High-speed PLA
SFast PLA / High flow PLA
Lower viscosity / melts easier to sustain very high print speeds
TPU
SThermoplastic Polyurethane
Perfect layer adhesion; extremely impact resistant; nearly indestructible

Strengths Comparison
High-speed PLA Strengths
- Lower viscosity / melts easier to sustain very high print speeds
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
High-speed PLA Caveats
- Even lower heat tolerance can be problematic in hot climates
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 High-speed PLA or TPU better for 3D printing?
High-speed PLA is generally rated higher (Tier S) compared to TPU (Tier S). However, the best choice depends on your specific needs: High-speed PLA is best for Lower viscosity / melts easier to sustain very high print speeds, while TPU is best for Perfect layer adhesion; extremely impact resistant; nearly indestructible.
What are the temperature differences between High-speed PLA and TPU?
High-speed PLA prints at 190-230°C nozzle / 50-60°C bed. TPU prints at 200-240°C nozzle / 30-60°C bed.
Do High-speed PLA and TPU need an enclosure?
High-speed PLA: not needed. TPU: not needed.
Which is more beginner-friendly: High-speed PLA or TPU?
Both High-speed PLA and TPU are beginner-friendly options.
