Stratasys Inc. has announced findings from an independent and extensive performance study characterizing the effects of time, temperature and environment on the mechanical properties of polycarbonate (PC) and acrylonitrile butadiene styrene (ABS) plastic parts made via the fused deposition modeling (FDM) process. The first of its kind, this study provides data for manufacturers considering additive manufacturing for production parts or functional prototypes. According to the company, this information is imperative as additive manufacturing moves from its roots in prototyping to production of finished goods. “The finished product or prototype can be in service for extended periods of time and in varying conditions, so it is imperative to qualify the properties beyond published specifications,” the study stated. The independent study was conducted over a 52-week period by Loughborough University, UK. The study was conducted to evaluate the mechanical properties over time of polycarbonate and ABS plastic parts made with the Stratasys Fused Deposition Modeling process and how the parts stand up in the extreme environments of heat, cold, moisture, and dryness.
