Direct Laser Manufacturing (DLM) with coaxial powder injection (TRUMPF DMD 505 installation) was applied for
fabrication of 3D objects from metallic and ceramic powder. One of the advantages of DLM is the possibility to build
functionally graded objects in one-step manufacturing cycle by application of a 2-channel powder feeder. Several models
with different types of material gradients (smooth, sharp, periodic) and multi-layered structures were manufactured from
SS, stellite (Cobalt alloy), Cu and W alloys.
Technology of Selective Laser Melting (SLM) was applied for manufacturing of net shaped objects from different
powders (PHENIX PM-100 machine) : Inox 904L, Ni625, Cu/Sn, W and Zr02-Y2O3. Performance and limitations of
SLM technology for fabrication of elements for chemical and mechanical industries are analysed. Two-component
objects (Stainless steel /Cu - H13/CuNi) were fabricated in a two-step manufacturing cycle.
