Laser Sintering of 3D Printed Materials

Additive Manufacturing (AM) offers the possibility of miniaturizing components with increasingly complex geometries, which cannot be achieved easily with traditional processing methods. Selective Laser Sintering (SLS) is one such AM technique in which the object is built layer by layer.

SLS suffers from low mechanical stability and reproducibility of the products. The study of coalescence during sintering will provide more insight in the properties of product, eg. porosity, layer adhesion.

Therefore it is important to describe the coalescence of particles during SLS and establish a relationship between the sintering process conditions and material characteristics to the generated microstructure and resulting mechanical properties. Finally these finding will allow us to optimize the 3D printing process by SLS.
