Graphite Grey PRO Series HT-PLA Filament - 1.75mm

The HT in HTPLA is for High Temperature, because this 3D printer PLA filament is designed specifically for annealing. Annealing is the process by which 3D printed parts are heat treated after printing to produce a long lasting, more durable and especially heat resistant part. If you love PLA but need part that can take the heat, HT PLA is the filament for you.

PRO Series PLA filament is specially formulated for precision 3D printing and manufactured in the USA.

PLA that can take the heat

This specially formulated PLA 3D printer filament is designed specifically for annealing. Annealing is the process by which a 3D printed part is heat treated after printing to product a long lasting, more heat resistant part. The HT in HT-PLA stands for High Temperature because after the annealing process parts made with this filament will be far more tolerant of high temperatures. The best part about HT-PLA is it prints just like standard PRO Series PLA, with only a slight increase in extrude temperature.

The annealing process

At MatterHackers we annealed parts in an oven at 65°C (150°F) for 1 hour. Once the pieces are printed, place all individual parts on a cookie sheet or other oven-safe surface. Preheat the oven to 65°C before placing the parts inside, as some ovens will heat to beyond the specified temperature before leveling out. Use a infrared thermometer to be sure the oven has settled at the proper temperature. After the parts have cooked, carefully remove and allow them to return to room temperature before handling or assembling.

PLA, aka Polylactic Acid, is a multipurpose material commonly used in 3D printing. PLA is a bioplastic, which means it is made from renewable natural resources such as corn starch and tapioca products. As a biodegradable material it is much better for the environment, especially compared to petrochemical-based alternatives (such as ABS).

Our PLA is compatible with nearly all 3D printers, including RepRap derivatives and those from MakerBot, Ultimaker, Bits from Bytes, Airwolf3D, Makergear, Printrbot, Bukobot, Type A Machines, and many others.

At MatterHackers, we prefer PLA as our default printing material due to its high strength and minimal warping.
