It uses liquid photosensitive resin as the raw material, which is solidified layer by layer through laser , gradually stacked to form a model.

Preheat the powder material to near the melting point, use a laser to scan the cross-section of the layer, raise the powder temperature to the melting point, and then sinter to form a bond. Repeat this process continuously until the entire model is formed.

The laser melts each layer of metal powder. The powder is sintered into a preset shape. Lower the bed, cover it with fresh powder, and proceed with laser sintering. Repeat until the model is completely printed.
