Suitable for

Lightweight, integrated parts

Surface finish: highly rough

3D printing is characterized by its ability to reproduce designs with a high degree of freedom. This makes it possible to generate integrated parts while eliminating the need for processes such as hollowing out, welding, and adhesion. However, due to the limitations of laser sintering, surfaces may require subsequent finishing.
