Polymaker has launched a new family of 3D printing filaments dedicated to high-speed 3D printing.
Extrusion. PolySonic PLA (polylactic acid) filaments exhibit a wide extrusion window, producing a an increase in flow rate at the same printing temperatures in comparison to regular PLA filaments, the company reports. This boost in extrusion efficiency allows users to build profiles with higher printing speeds before noticing the effects of under-extrusion on the printed part.
Forming. Polymaker scientists have optimized the rheology of the PolySonic so that it can transition from fluid to solid with near-zero shrinkage.
Mechanical Properties. PolySonic PLA shows only a 6% drop in mechanical properties when printing at high speed compared to the classic test specimen. In contrast, PolyLite PLA (regular PLA) witnesses a 24% drop when the speed is increased. This final factor allows PolySonic to print both fast and functional which has been the previous limitation to high-speed 3D printing.
Two Types of Filaments
PolySonic PLA, a high-speed 3D printing filament, builds printing profiles over 300 mm/s. Its fast extrusion rate, high precision, and interlayer adhesion enhance 3D printing speed. While accelerating printing efficiency, it preserves its inherent mechanical performance, making it suitable for various applications, including functional prototyping, artistic creations, and production of end-use products. It is initially available in 5 colors.
