Abstract
This study aims to develop a methodology for cleaning un-cured resin from the build platform and the printed part between material change during multi-material Vat Photopolymerization printing to prevent cross-contamination. Existing multi-material VPP printers and their cleaning methodologies were investigated. Through this investigation, an Ultrasonic cleaner and TPM solvent were identified as suitable cleaning equipment and detergent, respectively, for this application. A prototype was developed to evaluate the efficiency of the proposed cleaning method. An experiment was conducted using the fabricated prototype, which demonstrated a cleaning efficiency of 91.67% and the duration of the cleaning process was 280 seconds. Additionally, a multi-material VPP print using two colored resins was performed to validate the experimental results. The findings confirmed that the proposed methodology effectively prevents cross-contamination and facilitates good inter-layer connection between different resins during printing.Description
