Best PLA filament for cookie cutters.
We've printed cookie cutters on three printers using over a dozen filament brands. Here's what we've learned about which filaments produce the cleanest, most food-safe cookie cutters, and which ones to avoid.
The food-safety question, honestly
Let's address the big question first. PLA itself is derived from plant starch (usually corn) and is generally recognized as safe for food contact by the FDA. The raw material is non-toxic. The complication is that a 3D-printed object is not a smooth, sealed surface. FDM printing creates layer lines, and those tiny grooves can harbour bacteria that are difficult to wash out.
For cookie cutters specifically, the risk is low. The cutter contacts raw dough briefly, and the cookies are then baked at temperatures that kill bacteria. The cutter is not storing food or holding liquid. Most home bakers use 3D-printed cutters without any issue. If you want extra peace of mind, coat the finished cutter with a food-safe epoxy or polyurethane sealant, which fills the layer lines and creates a smooth, washable surface.
That said, avoid filaments with added colourants or additives that aren't certified food-safe. Some metallic and glow-in-the-dark filaments contain heavy metals or phosphorescent compounds you don't want near food.
What makes a good cookie cutter filament
Beyond food safety, a good filament for cookie cutters needs to:
- Print cleanly at thin walls: Cookie cutter cutting edges are typically 0.4mm to 0.8mm thick. The filament needs to extrude consistently at these dimensions without stringing or blobbing.
- Hold dimensional accuracy: The cutter needs to match the STL file. Filaments with high shrinkage or warping tendencies will produce cutters that don't match the intended shape.
- Be rigid enough to cut dough: The cutting edge needs to press through chilled dough without flexing. Standard PLA is rigid enough. PLA+ and flexible PLA blends can be too bendy at thin walls.
- Not warp on the bed: Large cookie cutters (80mm+) need good bed adhesion to avoid corner lifting that distorts the outline.
Our top picks
1. Bambu Lab PLA Basic (best overall)
Bambu's house-brand PLA has been our default for the last year. It prints exceptionally cleanly, has minimal stringing, and holds tight tolerances on thin-wall prints. The matte finish looks good on finished cutters. It's priced competitively at around $18-$20 per kilogram, and the spool design (cardboard with a desiccant slot) keeps it dry in storage. Available in 24 colours, all of which print identically in our testing. Our standard cutters are printed in white or natural.
2. Prusament PLA (best for precision)
Prusa's house filament is manufactured to a diameter tolerance of +/-0.02mm, which is tighter than most competitors. For cookie cutters with very fine detail (letter cutters, intricate florals), this consistency matters. The prints come out dimensionally accurate and the surface finish is smooth. At around $25 per kilogram, it's more expensive than Bambu but worth it for detail work. The Galaxy Black colour is excellent if you want your cutters to look impressive in photos.
3. Hatchbox PLA (best budget option)
Hatchbox has been a community favourite for years, and for good reason. It's reliable, affordable (around $22 per kg), and available in a huge range of colours. Print quality is a step below Bambu and Prusament on thin walls, with slightly more stringing, but for standard-sized cutters it produces good results. If you're printing a lot of cutters and want to keep costs down, Hatchbox is a solid choice.
4. Polymaker PolySafe PLA (best for food safety concerns)
If food safety is your primary concern, Polymaker's PolySafe line is specifically certified for food contact under FDA 21 CFR and EU 10/2011 regulations. It's more expensive (around $30 per kg) and available in fewer colours, but it removes the guesswork about additives and colourants. Print quality is good. If you're making cutters for a bakery or for sale, this is the safest choice from a liability standpoint.
Print settings for cookie cutters
Regardless of filament brand, these are the settings we use for all our cookie cutter prints:
- Layer height: 0.2mm (standard) or 0.16mm (for fine detail)
- Wall count: 3 walls minimum for the cutting edge, 4 for the handle
- Infill: 0% for the cutting edge section (solid walls only), 15-20% for the handle/grip area
- Print speed: 50-80mm/s for the cutting edge, faster is fine for the handle
- Nozzle temperature: 200-210C for most PLA brands
- Bed temperature: 55-60C
- Cooling: 100% fan after the first layer
The most common mistake is printing too fast on the thin cutting edge. Slow it down and the edge will be cleaner and stronger.
Filaments to avoid for cookie cutters
A few categories to skip:
- PETG: It's food-safe and strong, but it strings badly on thin-wall prints and produces a rough surface that's hard to clean. Stick with PLA.
- PLA+ / tough PLA blends: These add flexibility to reduce brittleness, which is good for mechanical parts but bad for cookie cutters. The cutting edge needs to be rigid.
- Silk PLA: The glossy finish is attractive but the filament tends to be brittle at thin walls. Cookie cutters printed in silk PLA crack more easily under pressure.
- Glow-in-the-dark filament: Contains strontium aluminate particles that are abrasive (they wear out brass nozzles) and not food-safe.
