SLS and SLA belong to 3D printing technology. Let's understand their differences:

SLS printing is the acronym of Selective Laser Sintering.

The solid material is compressed into shape by heating and/or boosting pressure without liquefaction.

To put it simply, the construction surface of these machines will be paved with a layer of powder material and heated to a temperature just below the sintering point of the powder. The control system controls the laser beam to scan on the powder layer according to the profile of the layer, so that the temperature of the powder rises to the melting point, and then it will be sintered and bonded to the formed part below. After the sintering of one layer of cross section is completed, the worktable reduces the thickness of one layer, and the paving material is paved on it again. Repeat this process until the entire model is completed.

SLA is to scan the liquid resin point by point by the laser under the control of the computer according to the contour of each layered section of the intended printing object, so that the thin layer of resin in the scanned area will have a photopolymerization reaction, thus forming a thin layer section of the printing object. When the first layer is cured, move the workbench and apply a new layer of liquid resin on the previously cured resin surface for the next layer of scanning curing. The newly solidified layer is firmly bonded to the previous layer, and this is repeated until the object is printed.

JTR can provide not only SLS printing services and SLA printing services, but also other FDM 3D printing services. If you want to use 3D printing to manufacture parts or finished products, you can contact us and let JTR solve the problem for you.
