Selective laser sintering (SLS)

Selective laser sintering (SLS)

First of all: ”sintering” is when you make objects by heating powder. With SLS, the powder is often thermoplastics, ceramic powders or metal powders. This method starts with a flat bed of powder and laser above the powder bed. The laser heats powder at the coordinates that the computer tells it to. The powder at the coordinates become solid and just like that the first bottom layer of the object is made. The layers are really thin, much less than a millimeter! When the first layer is ready and the powder that was exposed to laser has stiffened, a new layer of powder is placed on the bed and the process is repeated. This continues until the whole object is complete. The great thing with using powders is that the power help to stabilize the construction while the object is created.

CandyFab printing system uses granulated sugar (like sugar powder) and heated air to construct 3D food-grade objects for art and for fun. We’ll have to guess that the art is used indoors…
