3D printing photosensitive liquid resins are made of carbon molecules in the form of short chains (monomers and oligomers) that combine into longer chains when exposed to certain wavelengths of light, polymerizing into solidified rigid or flexible geometries, becoming hardened plastic. In 3d printing this solidification process by means of UV light is known as “curing”. Before the resin is finished curing, it is toxic to touch. Resin releases irritants and pollutants.
“When using 3d printing resin, always work in a well-ventilated area and use protection gears to protect you and others”.
Read carefully the instructions for your resin and keep in mind that UV 3d printing resins:
- Irritate the skin: Liquid 3d printing resin in direct contact with the skin can create dermatitis.
- Irritate respiratory system: Resins produce fumes. If you don’t work in a well-ventilated area, molecules from the fumes will get into your lungs and cause irritation.
- Harmful when ingested or exposed to eyes: Never let resin near or into your eyes or mouth even when they’re specifically marked as non-toxic.
