Bambu Lab PLA Pure Filament 1.75mm 1kg

Five ingredients, and that's the whole recipe. PLA Pure strips the formula back to the minimum, and every one of those ingredients — pigments included — is certified to EU food-contact safety standards. Fewer ingredients, cleaner ingredients, and noticeably lower emissions while it prints.

Built for anything that ends up in a kid's hands or sits on a kitchen counter: toys, cookie cutters, dog bowls, gifts. It prints like standard PLA underneath — same cool, low-warp, no-enclosure behaviour — just with the ingredient list tightened up and a shorter colour run while Bambu scales it out.

Spool or Refill?

Spool — Comes on a reusable Bambu spool. Pick this for your first roll of a colour.

Refill — Filament only, $2 cheaper, needs an empty reusable spool to mount on.

Worth knowing

Every ingredient in PLA Pure — including the pigments — is food-contact certified, SGS-tested against EU Regulation (EC) 1935/2004: overall migration, heavy metals, primary aromatic amines, bisphenols, and an odour/taste check all pass. It also meets EU toy-safety standard EN 71.

That certification covers the raw filament, not the finished print. FDM parts are built layer by layer, so they're not watertight — gaps can trap moisture and bacteria the way a moulded or glazed surface wouldn't. Treat prints as food-adjacent (bowls, scoops, cutters used on dry food), not as a substitute for food-safe tableware.

If the "pure" part matters to your print, skip a brass nozzle — it can shed trace metal into the melt, which works against the whole point of this filament. Stainless or hardened steel, ideally a nozzle that hasn't printed anything else or run cold pulls to ensure the nozzle is clean.

Storage

Bambu specifies under 20% RH, sealed with desiccant, and rates this one for about 18 days in open air before it's due a re-dry. A sealed box with fresh desiccant does the job, or a filament dryer if you have one.

As filament takes on moisture you'll hear popping or hissing at the nozzle, then see stringing and rough surfaces, and eventually the strand goes brittle enough to snap in the tube. That's almost always moisture, not technique. Dry it at 50°C for 8 hours and it usually comes back.
