This document discusses how Unisource Engineered Solutions used 3D printing to create more realistic packaging prototypes. Specifically, it describes how UES used an Mcor Matrix 3D printer that prints with standard office paper to produce durable paper prototypes of their thin-walled, molded pulp packaging. These realistic prototypes enhanced customer understanding, satisfaction and increased sales by preventing confusion between prototypes and final products. The paper prototypes also provided benefits like shortened development time, reduced costs and an improved perception of UES.
