Microfabrication of different components has become an important part of the modern fabrication caused by the necessity of producing smaller and smaller parts with very precise details. Especially in the fields of microelectronics and medical applications where size can be a limiting factor due to the requirements, microfabrication technologies are unavoidable. These processes can be mechanical, chemical, or thermal for metal and polymer parts. Many of those technologies are adaptations from the macro fabrication processes like micro injection molding, where the process is scaled down towards achieving microstructures. For polymers one of the processes, the micro 3D-printing stands out due to the wide range of geometrical possibilities which can be built up even in the smallest range of the microscale. Based on Stereolithography (SLA) and Digital Light Processing (DLP) printing technologies, many geometries which wouldn’t be possible using other fabrication methods, can be realized using this technology. The process doesn’t require any tooling and is a rapid way of creating a microstructure out of the CAD data whether it is for receiving a functional prototype or even the final production of parts. The paper presents a short overview of microfabrication and the possibilities of 3D micro printing as well as the basics of this technology with examples of different experimental parts and the potential and challenges of DLP technology. Furthermore, the influence of one of the critical process parameters, the UV intensity, on the mechanical properties of printed parts was tested and assessed.
