The laser scanning in the rapid prototyping process should correctly scan a 2D pattern. Once dislocation occurred during the scanning, it may lead to a green part with incorrect shape or failure of fabrication. The aim of thesis is to solve the problems by integrating a digital galvanometer scanner into a rapid prototyping system. By designing and making an automatic control system, a correct pattern can be achieved. A homemade control circuit with Human-Machine Interface program (HMI) was integrated to a new digital galvo-laser engraving control board and digital laser galvanometer scan head to construct a new digital galvanometer scanning system. Furthermore, comparing with the roundness of the scanning pattern scanned by the analog galvanometer scanning system, the new system could achieve a better result. To verify the feasibility of making ceramic parts with the new digital galvanometer scanning system, the parts were fabricated of ceramic slurry with existing homemade apparatus.
