Bambu Lab has launched a new filament: PLA Pure for safer product 3D printing
Today, Bambu Lab has announced the launch of PLA Pure, a filament engineered for cleaner, safer FDM 3D printing, promising safety and reliability.
PLA Pure draws on materials present in everyday life, and each of the five ingredients is certified compliant with EU Regulation 10/2011, meaning the filament is safe for contact with food.
The filament is made up of Polylactic acid (PLA), which is derived from corn and sugarcane; acrylic copolymer, which is commonly found in children’s toys; colour pigments used in baby tableware; EBS (ethylene bis-stearamide) used in food packaging; and the type of talc used in biodegradable drinking straws, which has been independently tested and verified as asbestos-free.
Most filaments marketed as food-contact compliant are tested only as finished products, but PLA Pure is verified ingredient by ingredient, from the base material to the pigments.
Raw materials are supplied by global manufacturers including TotalEnergies Corbion, Dow, Chemours, and BASF, making compliance and traceability straightforward.
The filament also carries UL 2904 GREENGUARD certification, the recognised standard for 3D printer emissions that measures particulate matter and Volatile Organic Compounds (VOCs) for indoor air quality impact.
During testing, particle and VOC levels fell below what’s typically present in an average kitchen, living room, or office. In a four-hour continuous printing test, PLA Pure produced lower PM2.5 and PM10 emissions than a comparable filament under identical conditions, although proper ventilation is still recommended.
Most filaments rely on impact modifiers and flow agents to achieve consistent print results. PLA Pure takes a different approach: to keep the formula to five food-safe ingredients, Bambu Lab rebuilt the formulation from scratch, resulting in less residue, reduced nozzle buildup, and more consistent extrusion.
PLA Pure promises less stringing even without prior drying, cleaner surfaces so finished parts require less post-processing and strength which matches PLA Basic in mechanical performance, with layer adhesion comparable to most PLA materials on the market.
For easy set-up, all printing parameters are stored in the RFID tag and automatically read by the AMS system. Simply load the spool, let the material synchronise itself, and start printing.
When it comes to toy safety, the filament has passed EN 71-3 certification, the European safety standard that governs the migration of certain elements from toy materials.
Passing this test makes the material suitable for models meant to be handled and played with, like a toy kitchen plate, a small car, or a cat toy.
PLA pure is available now from Bambu Lab’s official store for $24.99 (with spool) or $21.99 (refill).
