SLS Prototype Vs SLA Prototype: How They Work?
How SLA 3D Printing Works?
After data processing, a proprietary software slicing program is used to import the 3D model and build support structures as needed.
The SLA machine is then instructed to print the STL file using a tank of liquid photosensitive resin. The tank is lowered with a construction platform on it. The UV laser beam focused through a lens scans a cross-section of the liquid surface.
Next, the rapid solidification of the resin creates a single material layer in the scanning region. A new resin layer is applied to the build surface when the first layer is finished, and the platform is lowered by 0.05-0.15mm.
The resin is then cured and bonded to the layer beneath as the next layer is traced. Continue in this manner until the portion is complete.
How SLS 3D Printing Works?
A platform with a small layer of powder inside the shaped chamber is coated.
A laser beam scans the powder according to the layer’s cross-section contour when heated to a temperature just below the polymer’s melting point, sintering the powder. The model’s hollow and cantilever are supported by un-sintered powder.
The platform’s thickness is decreased by one layer when a cross-section has finished being sintered, and the laying roller then applies a layer of uniformly dense powder on top of it to get it ready for the sintering of a new cross-section.
The procedure is repeated until the solid model is obtained after all layers have been sintered.
