Abstract
A cross-linkable powder for use in a selective laser sintering (SLS) process for additive manufacturing is disclosed as well as a novel manufacturing process to form a 3D object using said cross-linkable powder. The manufacturing process makes it possible to create interlayer covalent bondings between deposited layers of cross-linkable powder such that 3D printed objects are achieved having improved mechanical strength, less object deformation and/or no warping.
