Comparative Analysis of FDM Model With Z-Printed High Temperature Mould Cast Part: Assessment of Dimensional Precision and Surface Integrity

Abstract
Z-printed moulds for metal casting and FDM modelling are categorically defined as rapid casting and prototyping additive manufacturing systems respectively. Both the 3D Z-Printer and FDM are usually considered for pattern manufacturing for mould making and general model demonstrations during product designing phase. But the quality of finished parts made from both technologies may varied as they possess various ranges of surface finish, mechanical strength, dimensional precision and therefore having different manufacturing cost due to type of machine design and processing. In this study in-depth analysis of the process capabilities of both additive manufacturing systems and comparison in terms of dimensional accuracy and surface finish have been carried out using FDM TITAN and Z-310 Z-printed mould cast part. Laser Scanner and Surface Roughness Techniques have been utilized for computing the dimensional accuracy and surface finish. The results suggested that for better rapid prototyping for polymeric materials FDM system will be selected to meet the rapid prototyping quality needs on the bases of dimensional accuracy and surface finish for the application of silicon rubber moulding due to its temperature limitations. While for rapidly cast the metallic prototypes or functional parts for extra strength Z-Printer Technology is more feasible.
