Theoretical and Constructive Aspects Regarding Small Dimension Parts Manufacturing by Stereophotolithography

StereoPhotoLithography (SPL) by laser allows three-dimensional objects obtaining. The paper presents some aspects related to a device consisting of a stage performing displacements on x and y directions, controlled with PC, by means of a controller and a motion interface. This device is designed to be a subassembly of a μSPL installation. There are given different geometric patterns, as preliminary test, generated by using a program in LabView to command the servomotors that act the x-y stage. There are given, also, the results of the authors as regards the 2 1⁄2 D configured parts by using the standard photoresist technology, starting from the idea to combine SPL with thick resist UV lithography.
