Tough Pro PLA+ in Flat Dark Earth, 1.75mm Our Tough Pro PLA+ is built for your most demanding 3D printing projects. Formulated to combine the easy printability of PLA+ with the toughness you need for functional parts, Tough Pro PLA+ delivers smooth, reliable prints plus industrial-grade impact resistance — all while staying true to a sustainable, US-made material lineage. Made in the USA from genuine NatureWorks 3D870 Ingeo PLA, Tough Pro PLA+ is a sustainably sourced bio-plastic with a standout eco-profile. This filament is designed to meet higher performance requirements without sacrificing the user-friendly experience you expect from PLA+. In real-world testing, Tough Pro PLA+ parts show significantly higher impact toughness than standard PLA+ and outperform many ABS-ready blends, giving you a reliable option for prototypes, jigs, and end-use components. What sets Tough Pro PLA+ apart
- Unmatched toughness: Roughly 8.8x the impact toughness of standard PLA+ in practical tests, making parts that survive drops, bumps, and handling in ways standard PLA+ simply can’t match.
- Heat resistance that rivals ABS: Even before any post-processing, Tough Pro PLA+ resists heat better than typical PLA+ formulations, helping parts hold up in environments that see higher temperatures.
- Post-process ready (annealing): You can anneal your design after printing to gain even greater heat resistance and impact toughness. Note that annealing can cause 1–2% dimensional shrinkage, so plan accordingly and constrain prints tightly during the process to minimize warping.
- Practical for industrial-grade use: Tough Pro PLA+ was designed to combine the best traits of ABS-like toughness with PLA+ printability, enabling robust prototypes and durable end-use parts without the complications of more abrasive engineering resins.
- Proven performance on popular printers: Test parts were printed on a Bambu Lab X1C at 0.2 mm layer height with no annealing, illustrating strong real-world viability across modern desktop systems. Annealing for maximum performance
If your goal is maximum heat resistance and impact strength, annealing is a proven option for Tough Pro PLA+. Plan for a controlled process, as the material may shrink 1–2% during annealing. To minimize warping, secure the part tightly using gypsum or salt flour during the heat treatment. While annealing isn’t always practical for every part, many engineers find it worthwhile for load-bearing fixtures, functional jigs, or components destined for warmer environments. Printing guidelines that unlock the best results
