Three-dimensional-printed molds and materials for injection molding and rapid tooling applications

  • John Ryan C. Dizon (a1) (a2), Arnaldo D. Valino (a1) (a3), Lucio R. Souza (a1), Alejandro H. Espera (a1) (a4) (a5), Qiyi Chen (a1) and Rigoberto C. Advincula (a1)...


This Prospective covers an overview of the injection molding process and the importance of mold design and tooling considerations, important material requirements and thermal properties for molds, polymer material requirements for injection molding, mold flow analysis, and the promise of using the 3D printing process for mold fabrication. The second part demonstrates the injection molding process using 3D-printed polymer molds and its suitability for low-run productions. 3D-printed molds using stereolithography and fused filament fabrication have been injected with polylactic acid, and the quality of the injected parts was assessed in terms of dimensional accuracy and the damage mechanisms during fabrication.
