For a print this size, I wouldn't use resin. I imagine he used FDM. You might want to consider printing food-related items in PLA. The ridges do present a problem, but could be mitigated by sanding or coating (again, food-grade).
- willis936 5y agoPLA isn't considered food grade but a marginally more expensive and difficult to work with, PETG, is food grade.
- Steltek 5y agoI don't think switching to PETG is an automatic win? You still have a rough, porous surface that can trap bacteria. I stay away from food-related prints but I thought the best method was to print in whatever reasonable material you want and then coat it in something food grade, like resin. Then you get the material and print properties of PLA, PETG, whatever but food safe.

- GravitasFailure 5y agoI believe they were suggesting using a food safe epoxy resin coating, not using a resin printer to make the part. Honestly, since it's dry food the usual food safety risks are fairly limited.
