Overview
PLA+ is a modified PLA formulation that adds impact modifiers and toughening agents to the base polymer. The result is a material that prints just as easily as standard PLA but is noticeably less brittle, with improved layer bonding and a slightly higher heat deflection temperature.
PLA+ is the ideal upgrade for anyone who loves PLA's printability but needs parts that can withstand mild impacts without shattering.

Advantages & Limitations
Advantages
- ✓Tougher than standard PLA - less likely to snap under impact
- ✓Prints just as easily as PLA at the same temperatures
- ✓Better layer adhesion - stronger finished parts
- ✓Good surface finish with minimal post-processing needed
Limitations
- ✗Still limited heat resistance compared to PETG or ABS
- ✗Not biodegradable in the same way as standard PLA due to additives
Applications

Printing Tips
Print PLA+ at 205–230 °C with a bed at 55–65 °C. Settings are nearly identical to standard PLA. The added modifiers may require slightly higher print temperatures for optimal layer bonding. Store in a sealed bag with desiccant.
Frequently Asked Questions
How different is PLA+ from regular PLA?
PLA+ prints identically to PLA but produces tougher parts. The elongation at break improves from ~6% to ~15%, meaning parts flex more before breaking. You will notice the difference if you try to snap a test part by hand.
