Given how often parts are out of stock on the Bambulab US online store, and considerably lead times for them to come back into stock, what’s a good list of parts to buy when they’re available to keep on hand? Here’s my start for a list:
Silicon covers
Extra hot-end in whatever nozzle diameters you may ever want to use.
The ooze guard (or whatever it’s called). Mine got bent when I attempted to finish a print after a power failure. I managed to bend it back into place, but having an extra on hand may not be a bad idea if it were to ever to get severely bent beyond recognition?
PTFE tube? If I’m not mistaken, it’s considered a consumable. It has a star shaped interior, so maybe Bambulab is the only source for it?
Extruder? I kept an extra on my X1C for instant Blob of Death recovery, but I’m unsure whether or not it would be needed for the H2D, as I’ve never had a Blob of Death experience on the H2D, and maybe the safeguards would prevent it from ruining the extruder. Anyone have any thoughts on this?
Please post suggestions for whatever else should be on the list.
Heaters assembly’s, silicone socks, purge wipers (when they are available to buy). Extruder gear, filament guide, cutters, buffers. Ooze blocker like you mentioned. I also happened to pick up the cam for the nozzle switching, idlers, cutter levers. I stocked up on a ton of the cheaper priced tool head items to ensure if something breaks, I have it on hand.
I would include the heating elements (and probably hotend seats) into the stock.
Bambu might replace them for you if it’s on their fault, but keeping a working part stock is always nice.
depends. some of them do show premature fails and wearouts. I would suggest one to move the toolhead to each of the 4 corners and check whether the ptfe tube is bending the buffer and extruder inlet too much. If so try optimise the ptfe path, give it a couple more centimeters for example. I replaced mine with a tube that is ~4cm extra long than the stock, because my stock tube would make the buffer bump really hard when it’s reaching the front left corner.
I didn’t see a 40 pack (at least not immediately) but I did find a 20 pack. Are you finding that the aliexpress silicone sock quality equally as good as Bambulab’s OEM H2D silicone socks?
I’ve become more aggressive in replacing my silicone socks, as they tend to accumulate filament bits, which it seems may(?) start contributing to build-up of crud on and around the nozzle. Especially given the low aliexpress price, I think I’d be more inclined to more often toss them out pre-emptively as a cheap consumable rather than scrape the inside clean and wait for failure.
Yeah, but considering this part (the whole heating assembly) has some thin cables that might easily break, I would consider to have at least a pair of them in the stock.
Yes it was just two 20 packs I purchased. They seem to be good quality, identical to OEM minus the Bambu Lab markings. One of the few “aliexpress” items Im willing to use together with build plates.
(I borrowed this name from someone else and I find it quite straightforward…)
