Purpose
The purpose of the 3-D Printer Program (3-D PP) is to identify, evaluate, manage, and reduce potential health risks associated with the use of a 3-D printer(s). In some 3-D printing processes, thermoplastics are heated, nozzle extruded and then deposited onto a surface to build the object. Since most 3-D printers do not have exhaust ventilation or filtration accessories, placement of the printer and selection of printing materials must both be carefully considered. There are both chemical and physical hazards associated with 3-D printers, which are determined by the type of printer, chemicals used for print materials, and parts finishing process:
These hazards include:
- The generation of ultrafine/nano-sized particles
- Chemical vapors (E.g., styrene, acrylonitrile, or formaldehyde, etc.) depending on the media being used
- Generation of heat and contact hot surfaces Mechanical hazards from moving parts
- High Voltage
- Ultraviolet light
- Use of tools to remove and finish parts
