3d printing advice

I could do with some advice as I know nothing about 3d printing...

I've found this latch which I could use to replace the broken one on my bread maker.

Question is whether it's possible/worth it.

According to panasonic the machine bakes at 150C - 170C. I expect that the latch will not get quite this hot but the whole machine casing does get warm so the internals will get getting pretty toasty.

Will a 3d printed part survive these sort of temperatures? Would there be a recommended filament material?

How much am I likely to have to pay someone (I can buy a complete new dispenser from espares for £25 delivered so am guessing it's may not worth printing unless doing so personally)?

Short answer, no. Common printing material is PLA which won't be happy, other filaments will do better but still aren't suitable.

Bit of discussion in the comments on that link re. temperature resistance but no-one bothered coming back with any results. I’d have thought PETG would be ok - starts to deform at 80 degrees, the outside of the machine won’t get that hot surely?
otherwise a more technical material like Nylon or PC would be fine, you’d need a higher end printer for those though.
Ultimately though yeah, unless you have access to a 3d printer (in which case it’d be a no-brainer to try it, one of the reasons they’re so useful!) £25 delivered for a part guaranteed to work is not terrible.

I doubt anything on the outside of a kitchen appliance will get that hot. It woudn't be very safe. I'd give it a go and see what happens.

If you want to print a test I could do you one and see what happens.

I've got a Lazer temp probe, next time I cook a loaf I'll see if I can get a rough temperature around that area.

If it's not so hot I'll maybe take you up on the kind offer but I suspect that it will go over 100C - the latch is internal and is in direct contact with metal parts so I expect radiation + convection on the inside will make it pretty hot.

How much load is the latch under? Enough to break the stock part I guess... The problem basically is that while the part won't <melt> until a reasonably high temp, if it's under load then as soon as you get above the glass temp you have a risk of deformation. So it's not just about the heat but also the stress.

ABS is probably better here than PETG- people default to petg for structural parts now and it'svery durable but its heat resistance isn't that much more than pla, typical ABS will get you over 100. Nylon better still and very strong but less people can print it. Also ABS is very workable- if you have a fit issue or roughness or similiar you can trim or sand it easily.

I could have a crack at it but tbh I've not printed in ABS for years so it may not come out brilliantly...

TBF the other question is how much work it is to fit, £25 might be a small price to pay for a one-and-done repair compared to possible timewasting and faff with a print.

way to drip feed 🙂 yeah that explains then on the link why people were considering cutting it out of metal. No, I doubt ABS or other common 3d print materials will be suitable. Possibly Nylon, probably PC would be ok.

Terrmometer shows 135 at the end of baking so I guess thanks for the offer but likely much too hot.
