3D Printing Polymers: Testing Repeatability of HP Multi Jet Fusion Printers

Authors: Karen Rivas

Additive manufacturing is the process of building a 3D part by building up layers of materials. This form of manufacturing has adapted from being used for rapid prototyping to mass production of products in recent years. This study will perform a characterization of a test artifact to be used for future developments of HP Multi Jet Fusion 3D printer to study repeatability. This is done by printing a proposed NIST Test Artifact on 3 printers to test for dimensional accuracy and precision. Alongside with the test artifact, Type IV Dogbones will be printed to determine mechanical properties of the printer as well. This project serves as a step to implement 3D printing technology to medical devices such as prostheses in the future.
