  • DIY Selective Laser Sintering FAQ RepRap

    Key process in SLS is sintering, which is basically a process when powder particles diffuse across the boundaries of the particles, fusing together and creating one solid piece. It is based on atomic diffusion, which occurs in any material above absolute zero, but it occurs much faster at higher temperatures.
