Layer Manufacturing techniques allow producing complex three dimensional objects with nearly no geometrical restrictions. The aim of this work is the extension of Layer Manufacturing towards Direct Precision Manufacturing based on both a new material and machine. Hybrid oligomers of the Ormocer class offer defined material properties, while a frequency-converted solid state laser is applied to provide the requested manufacturing precision. Specially configured Ormocers with adapted viscosity and optical penetration depth are investigated for their use in laser based Stereolithography. Azophenyl-based UV absorbents are used to adjust the optical penetration depth, while multifunctional acrylate monomers are used as reactive thinners for viscosity adjustment. The polymerization process is optimized as a function of the laser fluence with main emphasis on the functional group conversion and process resolution. Based on the results gained within this thesis, highly precise, complex and brittle hard precision components are producible. As proof of concept, a demonstrator part for flow cytometry applications is produced.weiterlesen
