The processes in the plastic powder are of a thermal nature. Throughout the laser sintering procedure, the plastic powder is briefly heated to a temperature above the melting point by direct exposure with the laser beam. A solid body is produced by this heating and the subsequent cooling. Density and residual porosity of the part produced depend of the exposure parameters and the exposure strategy.

In each layer the cross-section of the parts is exposed using the laser beam. The exposure criteria are chosen such that the exposed locations are bonded to the layer underneath that is already strengthened. In this way three-dimensional parts are produced layer by layer. Plastic powder material is used layer by layer on a structure platform and solidified layer by layer ways of a computer-controlled laser beam.

The recorter is filled with plastic powder and uses an approx. 5mm thick base layer to the structure platform. I Found This Interesting begins. Throughout this process the recoater is filled once again, the building platform decreased one layer thickness and a new layer of plastic powder applied. The computer system managed laser beam then exposes the shapes and the areas exclosed by the contours in accordance with the part information defined.

Functional Models A practical model does just that: it operates. These later-stage models are often made from products similar to what will be used in an end product, to confirm that whatever will work as planned. Engineers at this stage pay attention to efficiency: does it fit, does it function, do load-bearing parts bear loads? Attention must be paid to detail, to how the final part will be made (specifically if this will be done in a different procedure than the model; for example, 3D printing a prototype for a part that will ultimately be injection molded) in addition to how the last part will be post-processed/finished.

While 3D printing might be the ideal innovation for both quick prototyping and serial production of the last part - think about, for instance, cases of mass personalization - this will not always be the case. Prototyping need to take into consideration the eventual production procedure to be used, and later-stage prototypes need to use the exact same materials and suit the proper manufacturing criteria as the final parts will be.
