New 3D Printing Material, Black Semi-Matte PLA
D printing material manufacturer ColorFabb has launched a new 3D printing wire. Compared with other PLA, black semi-matte PLA provides a smoother surface finish. Because it does not contain fibers, the wire achieves a high-quality finish. The new black semi-matte PLA can be used without having to adjust printer settings or parameters, which makes it easier for users to try.
In addition, ColorFabb also provides two black matt finish wires: XT-CF20 and PA-CF Low Warp. However, these materials require hardened steel nozzles for printing.
It is worth mentioning that the black semi-matte PLA provides a better aesthetic, while reducing the gloss of most PLA 3D printing. Therefore, the surface highlights are less obvious, and the final appearance is cleaner and more luxurious.
The new 3D printing materials can be printed at the usual PLA temperature and settings. This is a reliable and easy-to-use material similar to other PLA materials.
