The sintering starts by taking a model that is loaded from a virtual 3D file.The manufacturing process is prepared using specialised programs, by slicing the model into fine horizontal layers.In the initial step of the process, a fine layer of powder is exposed above the platform.
The laser beam then traces out the first layer of the model on the surface of the powder, causing it to sinter. platform is then lowered, exposing another fine layer of powder on the surface of the tank, ready to be sintered. After this the process is repeated, printing layer after layer until the entire three-dimensional object has been formed. This result is a block of powder with the models contained inside. After the block has cooled, the parts can be extracted manually from the polyamide block, before being sanded to yield a completely clean surface.
