In terms of safety, 3D printer filament is no different than other plastics. ABS is generally not considered food-safe, and has been found by the EPA to contain carcinogens. While PLA is thought to be a safer option, particularly for printed items that come in contact with food, its actual safety factor has yet to be 100 percent verified. A number of 3D printing companies have been developing food-safe filaments made from materials such as PET or other alternatives, and now South Korean 3D printer manufacturer ROKIT Inc., in conjunction with Kolon Plastics, is releasing what it claims are the world’s first fully non-toxic printer filaments.
ROKIT’s “Kitchen and Deco” filament is BPA-free, and according to the company, fully meets the US Food and Drug Administration’s requirement for materials in contact with food. It emits no carcinogens or endocrine-disrupting chemicals, and ROKIT assures us that it is safe to use for the printing of kitchenware and even baby bottles. The filament retails for $45 per 700g roll.
At this time, it appears as though ROKIT will continue to offer its standard filament lines in addition to the two new non-toxic ones; it will be interesting to see how the new ones sell in comparison to their traditional PLA, ABS and other plastic filaments. As people are becoming more health-conscious (one may even say health-obsessed), demand for proven safe materials is growing in every sector. We’ve covered a lot of ingenious eco-friendly filaments at 3DPrint.com, but food-safe filaments are still pretty limited. With its new non-toxic options, ROKIT is meeting a major demand in the 3D printing market.
