The vast majority of photoresins for 3D printing (also referred to as additive manufacturing or AM) and related technologies are toxic, non-biodegradable, and sourced from unsustainable feedstocks. Non-traditional approaches to 3D printing offer a way to break free of the traditional confines of unsustainable petroleum-based reagents and chemical methods that require toxic monomers.
