Fiberlogy Impact PLA vs TPU
Compare Fiberlogy Impact PLA and TPU filaments side-by-side so you can pick the right one for your 3D printing project.
Fiberlogy Impact PLA vs TPU: Fiberlogy Impact PLA is known for easiest to print, while TPU is known for excellent layer adhesion. Both have no enclosure requirements; Fiberlogy Impact PLA is less moisture-sensitive; Fiberlogy Impact PLA prints at higher nozzle temperatures (230°C vs 200-240°C). Choose Fiberlogy Impact PLA for easiest to print, or TPU for excellent layer adhesion.
Key differences at a glance

TPU
SThermoplastic Polyurethane
Excellent layer adhesion; extremely impact resistant; highly durable
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
Fiberlogy Impact PLA Strengths
- Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
- Stiff non-composite thermoplastic, good tensile strength
TPU Strengths
- Excellent layer adhesion; extremely impact resistant; highly durable
- Great for combat robots, tactical/rough-use parts
- Rubber-like parts (gaskets, grips, bumpers, wheels)
Considerations
Fiberlogy Impact PLA Caveats
- Creeps under sustained load
- Poor heat resistance, UV degradation, can shatter on drops
- Not great for sanding/gluing/painting/touch-ups
TPU Caveats
- Slow printing; retraction can cause jams (especially in Bowden setups)
- Stringing is common
- Very moisture sensitive; wet TPU prints poorly
