Development and demonstration of a multiple material stereolithography system

Oswaldo Alonso Lozoya, University of Texas at El Paso


The development of the first multiple material stereolithography (MMSL) system to the author's knowledge, as a retrofit of a multiple vat carousel assembly into an existing sterolithography (SL) system based on an existing patent application filed by Wicker et al. 2004, is presented along with a description of the retrofitted MMSL system operation. Use of three different photocrosslinkable epoxy-based resins to demonstrate the MMSL system capabilities, by means of customized multiple material tensile testing samples manufacturing, is also discussed, in an effort to characterize multiple material normal and shear bonding strengths through tensile testing. Single material testing results of customized sample geometries built on different orientations are included as well, providing supportive background on mechanical testing fracture phenomena characterization in both multiple material and single material samples. ^
