3D Printed Inserts for Medical Device Prototyping

This case study examines the application of Mantle's TrueShape™ metal 3D printing technology in reducing lead times and costs for a global medical device manufacturer. The manufacturer sought to determine if the new technology could meet the demands of high-temperature, high-pressure plastic molding while maintaining quality standards. Mantle produced four nose-detail slide inserts using P2X material, which were accurate within 0.001” and required no modifications to their surface finish. The entire process took four weeks, significantly less than the conventional twelve weeks. The cost of the finished mold was $21,000, compared to $63,000 for traditional methods. The study highlights the performance of the molded parts, which met all specifications for geometric precision and mechanical performance. The results indicate a 66% reduction in lead time and substantial cost savings, demonstrating the effectiveness of Mantle's technology in the medical device manufacturing sector.
