High Temp PLA
High Temperature PLA
Looking for increased heat resistance without the need to switch to ABS? Proto-pasta High Temperature PLA offers heat deflection of up to 88° C (190.4° F) compared to standard PLA of 45-54° C (113-135° F). This makes it a great choice for moving parts (gears, RepRap pieces, etc) or prints that would face moderately high temperatures. Our High Temperature PLA is white, but can be painted after annealing.
Proto-pasta High Temperature PLA is made from a mineral filled, impact modified PLA with a nucleating agent to help promote crystallization. Crystallization after printing is what gives this material added heat resistance, so post-print annealing is essential to activate the heat deflection qualities of this material.

How do I anneal my print?
You can anneal your finished prints several ways, the two easiest ways are by using hot (but not boiling) water or by placing it in a low temperature oven (newer oven models only). Follow these steps:
- Water Method: Find a pot large enough to hold your print and fill it halfway with water. On medium heat, heat the water until it reaches 95-115 C (200-240 F) (a cooking thermometer works great for this), turn the heat to low and submerge the print in the warm water bath for 6-10 minutes. Placing a lid on your pot will help the water maintain temperature.
- Oven Method: Many newer ovens often have low temperature settings (sometimes called "keep warm" or "bread proof"). Set your oven to 95-115 C (200-240 F), place your finished print on a tray, and set it in the oven for 6-10 minutes.
- SUPPORT YOUR PRINT! Because the annealing process will soften the plastic somewhat, it's best to support your print during this process.
Because 3D printers vary so much from model to model, and because many RepRap printers combine parts from several manufactures, we can't provide the optimum temperature for your machine. Generally, our customers find it prints just like standard PLA on their machines (at around 210° C), though others find success running it a bit hotter (around 220° C).
Do I need a heated bed? No, High Temp PLA does not require a heated bed or an enclosure.
