What it brings
PLA Tough+ is intended for parts that need more resistance to knocks than ordinary PLA, while retaining relatively easy PLA processing.
Impact-tolerant PLA
PLA Tough+
Higher impact tolerance with familiar PLA production practicality.

The engineer’s read.
Match the actual part geometry and service conditions to the grade and test context, not just its family name.
Selection verdict
Choose PLA Tough+ for indoor functional prototypes and repeatedly handled parts when impact tolerance matters, but heat and UV are not dominant requirements.
Printed properties.
HDT at 0.45 MPa; tensile, modulus and unnotched impact in XY. V3.0 TDS; specimens dried and annealed before testing.
| Property | Representative value |
|---|---|
| Density | 1.21 g/cm³ |
| HDT · 0.45 MPa | 61°C |
| Tensile strength · XY | 34.9 ± 1 MPa |
| Young’s modulus · XY | 1.86 GPa |
| Impact strength · XY, unnotched | 80.6 ± 9.5 kJ/m² |
Published test-specimen data is for comparison only. Orientation, conditioning, processing and geometry can change finished-part performance. Heat-deflection temperature is a standardised test, not a continuous-use rating.
Selection logic.
Practical reasons to choose or avoid this material for a specific part.
Advantages
- Much higher published unnotched XY impact result than PLA Matte
- Useful layer toughness for handled parts
- Good choice for indoor functional prototypes
Watch-outs
- 61°C HDT at 0.45 MPa is not a high-temperature service rating
- Impact values are specimen and orientation dependent
- Not a substitute for ASA in sustained outdoor UV exposure
