Comment on I need a cheap part to fix a bread machine that's under warranty. "We can send you a new machine."
PancakesCantKillMe@lemmy.world 4 weeks agoI’ll bet you could use some type of modern sealant to make a “rubber” gasket. Spooge it out onto a glass or stainless surface, shape it and let it dry. Trim to fit and viola. Bob’s your auntie.
In light of the hard times coming down the pike, we’ll all need to be more resourceful with mending and maintaining all the products that were planned to be scrap after one year (or warranty expiration).

Maybe food safe tpu printed gasket?
Chocrates@lemmy.world 4 weeks ago
Not sure about TPU, but can any FDM printed material be food safe? I thought the layers (even with sanding) harboured bacteria.

Based on this research paper, washing with soap and warm water is enough to remove harmful bacteria.

Been an while since I looked it up, but I thought it was depended on the material. PLA IIRC is somewhat porous and will harbor bacteria, for example.

I think tpu does come in food safe formulations. For a gasket that isn’t coming into contact with food, and wouldn’t regularly be washed anyway, I wouldn’t really have concerns. Especially if you can design the gasket thin enough to reduce the number of layer lines.
I’d have more concerns if the printed part came into direct contact with the food. Anything you’d want to put into a dishwasher is completely out of the question; thermoplastics don’t handle the high temps gracefully

One option is 3D printing a mold to fill with silicone sealant. If this is a part that fails regularly, the mold may be worth it. You then have a pretty broad array of food safe sealants you could use and don’t have to worry about your 3d printed part harboring bacteria.
