PLA PRO: The material behind our durable molds
An upgraded PLA formulated for reusable molds.
Stiffer, tougher, and built for consistent results across many production runs
PLA PRO vs Standard PLA
| Property | Standard PLA | PLA PRO (our molds material) |
|---|---|---|
| Durability | Prone to cracking under repeated use | High toughness and impact resistance for continuous production. |
| Dimensional accuracy | OK for casual parts | ±0.02 mm tolerance for consistent fits and repeatable results |
| Surface finish | Often needs sanding and extra finishing | Smoother finish, less post-processing required; cleaner finished bath bombs |
What this means for your molds
Tougher walls, cleaner surfaces, and repeatable dimensions. Which means fewer failed batches and more consistent bath bombs.

Are these molds food-safe?
Yes. the PLA PRO filament we use is supplied as food-safe by the manufacturer. Follow our care instructions and avoid high temperatures. If you need explicit food-grade certification for a specific use, contact us and we’ll share the manufacturer documentation or help with certified options.
Can I clean PLA PRO molds in the dishwasher?
Do not use dishwashers or hot water. Clean with cold water and mild soap, rinse, and dry thoroughly. Avoid prolonged soaking — this preserves fine details and long-term durability.
How long will a PLA PRO mold last?
PLA PRO is built for continuous production and long life, but actual lifespan depends on the mold’s design and how it’s used. With sensible design (adequate wall thickness) and the care above, molds commonly last for many batches or years of regular use. We back every PLA PRO mold with a 2-year warranty against manufacturing defects when used as instructed.
How do I use these bath-bomb molds?
Place the bottom piece on a flat surface.
Slide the sleeve around the base to form the mold chamber.
Fill with your bath bomb mix, pressing evenly to capture every antler and detail.
Insert the top piece and press gently but firmly.
Remove the top, then slide off the sleeve, and lift the base.
Let your bath bomb dry for 24 hours before painting or packaging.
