| Abstract (eng): | Additive manufacturing (AM) is the dawn of new industrial revolution. It has a potential to revolutionize the way we make everything. Stereolithography (SL) is a rapid prototyping (RP) and manufacturing technology that enables the generation of physical objects directly from the CAD data files. In SL the products are fabricated layer-by-layer by curing the liquid resin. Microstereolithography (µSL) allows the fabrication of 3D parts with µm accuracy, including the re-entrant and curvilinear microstructures that are impossible to make by using conventional micromachining. In this thesis, a digital micromirror device (DMD) based Projection microstereolithograply (PµSL) setup has been built. Three different coatings for resin vat and three different resins have been tested for the fabrication purposes. Similar to Projection stereolithography (PSL), in PµSL, an entire layer is manufactured by irradiating its whole surface only once instead of scanning the layer cross-section. In the built setup, an UV LED is used as a light source and there is only one mobile element, the z translator, while all the other equipment is fixed. |
