ACCURACY OF HOLES CREATED BY 3D PRINTING (DMLS)

Popis výsledku v původním jazyce

Additive manufacturing (AM) is a very important topic nowadays, therefore this paper is focused on 3D printing of metal. AM for metal covers many methods that are divided into two basic principles: powder bed technologies and powder deposition technologies. This paper is limited to Direct Metal Laser Sintering (DMLS) that works on the principle of a powder bed. This method is based on sintering metal powder in thin layers, layer by layer. It is able to print different kinds of metal, for example stainless steel, maraging steel, Inconel, aluminium, titanium, etc. An EOS M290 machine with maraging steel MS1 powder was used for the experimental part of this article. Almost every mechanical component contains at least one or several holes, therefore it is important to describe how accurately 3D printing can create these holes. The effects of different holes positions on accuracy and geometry are compared. The influence of the size of the hole on the geometry change at the bottom of an arc is investigated. The goal of the experiment is to find the size of a hole which can be printed without support structures and which does not show signs of degradation of its geometry.
