Tips and Tricks
- Food-contact certification applies to the filament itself. Producing food-contact-safe 3D printed parts depends on equipment hygiene (particularly the nozzle), printing environment, and other factors.
- Due to layer lines, 3D printed parts are not suitable for holding liquid foods. Because of PLA's properties, do not expose 3D printed parts to temperatures above 60°C. For detailed guidance, see the PLA Pure Advanced Printing Guide on the Bambu Lab Wiki.
- Bambu PLA Pure is specifically developed for FDM 3D printing with both emission safety and contact safety in mind. When used with its default profile, it delivers excellent print quality and supports contact-safe performance. Because real-world use can vary across environments, conditions, and workflows, applications requiring a higher level of contact safety should follow additional guidance.
- Compatible with all 3D printers, AMS, build plate, and nozzles.
- For contact-safe finished parts, the use of adhesive is not recommended.
- Enhanced bed adhesion can alternatively be achieved by increasing the bed temperature.
- Dry before use to ensure the best 3D print quality and consistent finish. Store in a dry environment after use.
- The refill filament needs to be used with a spool. For detailed instructions on how to swap in the new filament using a Reusable Spool, please refer to our article: How to Refill Filament on MatterHackers Reusable Spools.
*Please Note
- Although this product has passed food-contact compliance testing at both the raw material and printed sample level, 3D printing is a multi-variable process. The quality and safety of finished 3D prints depend on factors such as equipment, printing environment, operating procedures, and post-processing.
- There is no guarantee that such user-produced 3D prints will meet applicable food-contact regulations, standards, or certification requirements in any jurisdiction.
