One of the potential advantages to acrylic is that it does not contain or release Bisphenol A (BPA) during hydrolysis (degradation due to material contact with water)1. The related plastic, Polycarbonate, contains BPA, and although the toxicity of BPA is inconclusive, it is simply not an issue with Acrylic. Most studies with government funding showed BPA to be a hazardous risk to health while many with industry funding showed lower to no medical risks. Regardless of the contradictory studies on the negative effects of BPA, certain types of Polycarbonate have been associated with its release. This has led to the advent of “BPA-Free” polycarbonate products (commonly shown on consumer products such as canning jars). Acrylic is another “BPA-Free” substitute for PC that is simply not toxic in solid form. That said, fumes from 3D printing with acrylic or from the molten material used during injection molding should not be inhaled and these manufacturing processes should be conducted in a well ventilated facility to avoid the potentially hazardous effects of gaseous polymer.
