Development of Domestic Equipment for Laser Additive Technologies by Melting Metallic Powders

摘要

The modern domestic installations used for the additive laser technologies based on layer-by-layer melting of metal powders are considered. An installation was developed and manufactured for the selective melting of metal powders by laser radiation scanned along a given contour. The installation is equipped with an automatic control system and makes it possible to grow 110 x 110 x 110 mm parts with an accuracy of 20 mu m and a growth rate up to 10 cm(3)/h. A KLP-400 installation was created for growing large-sized parts. The principle of operation of the installation is based on layer-by-layer laser facing with metal powders supplied coaxially with laser radiation. The installation can be used to produce parts 400 x 400 x 400 mm in size and about 500 kg in weight. The accuracy of the manufactured parts is 0.1-0.5 mm.
