ANALYSING THE PRE-DEFORMATION IN CASE OF SELECTIVE LASER MELTING PROCESS

In Selective Laser Melting technology, the deformation of a metal model depends on many parameters. A complex geometry needs simulation software to compensate for it. this research work, different types geometries, materials (316L, Ti64), and pre-deformation processes were analyzed in dedicated real model. The result shows geometrical difference between standard pre-deformed models simulated results printed parts. Due result, necessity pre-deformation, right choice parameters, process become more understandable predictable SLM technology. Of two raw materials, case titanium, higher internal stresses are generated during printing, so knowing what deformations is even important than steel. An that it clearly demonstrates where extent occurs post-printing operations, thus desired can better meet requirements.
