Assessing and reducing the toxicity of 3D printed objects

3D printing is gaining popularity by providing a tool for fast, cost-effective, and highly customizable fabrication. However, little is known about the toxicity of 3D-printed objects. In this work, we assess the toxicity of printed parts from two main classes of commercial 3D printers. We also developed a simple post-printing treatment that largely mitigates the toxicity of the STL-printed parts. Our results call attention to the need for strategies for the safe disposal of 3D-printed parts and printer waste materials. This work has been featured as the journal cover in Environmental Science and Technology Letters 3 (1): 1-6 and featured in Forbes, C&En, and Newsweek among other media outlets. The novel method for reducing the toxicity of printed parts are the basis for a patent (US20170120523A1) and the online tool, The PrintSafe Project.
