[14B-T6-06] Multi-Material Parts Production by Selective Laser Melting
キーワード:selective laser melting, multi-material parts, algorithm of recoating, cross-contamination, dissolution
The use of multi-materials may be viewed as a technically challenging and economically favorable manufacturing method.New patented method and SLM machine prototype for 3D multi-material parts production has been elaborated, where standard recoating systems with roller or blade can be used. A narrow fraction of powders of various materials with different medium particle size and special algorithm of powder layer recoating
are used. Method enables to separate the overflow powders of a various materials for re-use. The main mechanisms of SLM machine have been elaborated, physically modelled and produced. The cross-contamination effect has been studied experimentally. Not more than 0.1% cross-contamination are fixed.The influence of dissolution in liquid pool and shrinkage on accuracy of the position of a contact surface between various material have been given adequate consideration. The first industrial multi – material SLM machine is under consideration.
