Abstract

The article is about manufacturing a component with a precision circular hole by Digital Light Processing (DLP) additive technology for inserting another part. The accuracy of the hole itself depends on the choice of production technology and the appropriate material. Deformation of the inner wall of the hole prevents correct insertion of the part - nut of trapezoidal threaded rod. This article analyzes the feasibility of manufacturing a component using Digital Light Processing (DLP) additive technology and the use of liquid resin „Proto GRY“ for the manufacture a component. Among additive technologies processes, digital light processing (DLP) is typically seen as the technology capable of reaching the highest standards in terms of part complexity and precision. DLP technology rely on the use of light, typically in the UV region of the spectrum (380 – 405 nm), to cure a photosensitive viscous resin. This resin, typically composed of epoxy or acrylic and methacrylic monomers, will polymerize and harden when exposed to light. As light shines on the vat to create specific shapes or patterns that compose each layer, a solid object can be formed and extracted from the otherwise liquid resin.
