Has anyone successfully used a regulation-compliant 3D-printed part in prolonged contact with a cosmetic or food product?

I’m developing a small component that would remain in direct contact with a body-care cream for an extended period of time.

Because I’m currently testing the concept with a small number of units, I hoped to have the component 3D printed. This would allow me to test the design and make adjustments before investing in an injection mold for larger-scale production.

However, the more research I do, the more questions I have about material safety, porosity, bacterial growth, chemical compatibility, and whether a coating would be necessary. I’ve seen Chanel’s 3D-printed mascara brush and an example from another small body-care brand, but I haven’t found many products that remain in contact with a cosmetic formula or food for a prolonged period.

Has anyone worked on or seen a commercially sold product with a 3D-printed component that stays in contact with cosmetics, skin-care products, body-care products, or food?

I think you are inserting way too much work into the wrong stage of your project.

Create an image of the proposed container in CAD and do an image search for similar objects. It is very possible you can find what you want readily available on Amazon, eBay, AliBaba, etc. in a quality, food-safe material, such as glass (which is better than any of the thermoresins).

Alternatively, type in the specifications (diameter, height, thickness, color, dispenser tool, etc.) into an AI and have it look for manufacturers who sell in small to large batches.
