The Photopolymer Additive Manufacturing Alliance (PAMA) has published a new guide for the safe handling of liquid resins in 3D printing. The compact infographic summarizes important rules and recommended behaviors to avoid health hazards when printing with stereolithography or DLP systems.
According to PAMA, the UV-curable resins used must be handled with due care, similar to other chemicals. The guide therefore recommends wearing gloves, safety glasses and lab coats, as well as following basic hygiene rules. Furthermore, tips are given on clean and safe handling, from correct storage to waste disposal.
According to PAMA, it is also important to never tamper with or turn off the safety features of 3D printers. In addition, manufacturers’ resin safety data sheets should always be followed. In the event of skin contact, immediate thorough washing is advisable, and in the event of eye contact, rinsing with water for at least 15 minutes.
With this compact guide, PAMA aims to raise awareness of safe handling of printing resins. According to industry experts, there was still a need to catch up in this area in some cases. Since the resins are often handled outside closed systems, rules of conduct are important. The info sheet is available as a free download in PDF format on the PAMA website.
