Matter3D’s Wood Fill Performance PLA is formulated using genuine Vancouver Island wood fibers (10%) and the same great NatureWorks 3D850 resin as our other Performance line products. This engineering-grade Wood Fill PLA has higher bulk crystallization and is developed for high-heat ( 85 °C) and high-strength applications (stronger than most ABS materials). Performance PLA - Wood Fill is ideal for functional jobs, where greater heat resistance and impact strength are desired. This material saws well, sands well, and takes paint extremely well. Compared to other Wood Fill - PLA materials, that may not even contain real wood, Matter3D’s Wood Fill is made from genuine Vancouver Island cedar pulp. It even smells authentic when you print it! We recommend printing with a 0.6 mm nozzle; however, if you have your printer dialed in, it is possible to print using a 0.4 mm nozzle. Similar to our other Performance PLA products, the Wood Fill line offers the same ease of PLA printing without sacrificing print quality, compatibility, reliability, or part-performance.
