Best fit
PLA
Rigid visual and prototype parts where shape retention is the primary goal.
- • Does not target compliant or flexible part behavior.
- • Use a different route when elasticity is part of the design requirement.
Part behavior
PLA vs TPU for a compliant part
Compare a rigid visual-prototype material route with a flexible route for bumpers, feet, and gasket-like parts.
Best fit
TPU
Flexible parts, bumpers, feet, strain-relief features, and gasket-like uses.
- • Material handling and calibration become more important for flexible filament.
- • Start from the selected spool profile before the calibration pass.
Decision rule
Choose PLA when rigidity is the requirement. Choose TPU when the part needs to flex, absorb contact, or deform repeatedly as part of normal use.
