This technology is an augmentation of the SLS 3D printing process that allows bi-directional crystallization for faster 3D printing.
SLS is a popular 3D printing technology because it allows high levels of complexity and design freedom. However, limitations on printing speed are one of the greatest challenges to broader adoption of SLS technology.
This process uses a modified type of mask, which supports lateral crystallization growth in two opposing directions simultaneously. Bi-directional growth increases the grain size of polycrystalline film crystallized via SLS without sacrificing throughput. Requiring fewer irradiation shots to achieve a larger grain size, this process increases SLS efficiency, reduces wear on the SLS laser, and may reduce thermal degradation.
