Despite the remarkable mechanical properties and versatility of polycarbonate (PC) in 3D printing, it is vital to address safety considerations when working with this material. Polycarbonate filament, like other thermoplastics used in 3D printing, presents specific challenges and risks that require careful attention.
One of the primary safety concerns associated with polycarbonate 3D printing is the potential release of Bisphenol A (BPA) fumes when the material is heated. BPA is a chemical compound commonly found in polycarbonate plastics and can be harmful if inhaled. Proper ventilation and operating in well-ventilated areas are crucial when working with polycarbonate to minimize the risk of exposure to BPA.
In addition to the risks associated with BPA exposure, polycarbonate filament is relatively more expensive compared to other materials used in 3D printing. This factor can impact the overall cost-effectiveness of projects using polycarbonate. Proper storage of polycarbonate filament is also vital, as the material is hygroscopic and tends to absorb moisture from the environment, which can affect print quality and safety.
Furthermore, inadequate temperature control during polycarbonate 3D printing can lead to poor layer adhesion on the print bed, potential separation or cracking as the material cools, and warping. Proper temperature management, including maintaining the ideal bed temperature and nozzle temperature, is vital to ensure safe and successful printing with polycarbonate.
Lastly, polycarbonate 3D printing can result in oozing, where the printer’s nozzle releases small amounts of filament even when not actively printing. This can cause unwanted strings or blobs on the printed object, impacting its appearance. Manual adjustments and careful monitoring of printing parameters are necessary to avoid issues like oozing during the printing process.
