Hi All,
I had one of my printers catastrophically fail (Mk3) and need to order some new hot end parts (heater and thermistor) and maybe the full hotend assembly itself to be safe. These items are not in stock currently on the Prusa site. Are there any alternative places to get these from or do i simply need to wait?

If you’re in the US, Amazon has the Prusa hotend kit except for the PTFE tube (item E3DMK3MK3S). The PTFE tube probably can be salvaged from your existing hotend.
Otherwise you can just buy another, longer ptfe tube, trim it to size and use a pencil sharpener to get the angled part in the front
edit: trim it with a sharp knife by edging, not with scissors or pressing the knife into it
Where are you located?

in the US, 24v one is sold out which is what the MK3/s needs
If your old heater is still good just transfer it over.
cant the molten mass kinda janked up everything, wires melted and so on
Ah, blob of doom. If you heat up the printer and just leave it hot, maybe 275 or 280, for a while, it might work itself off. You can use a heat gun to make this faster but understand that it can melt the plastic parts on your printer too if you are not careful. Just heating up the hot end normally will get you 70 to 80% of the way there
Might be a good opportunity to move to the new E3D Revo hotend. Much easier nozzle swaps, plastic seeping becomes basically impossible as well since the nozzle and heat break are integrated.
thanks. ill look into it
I just switched over to the Revo last week. I love it so far. The only bad thing I’ve noticed so far is that they haven’t released hardened steel nozzles, and since the brass ones are still a little pricey, I can’t print with abrasive materials on it yet. But I trust that will all be solved soon, and I’m sure that it won’t be long before the nozzle prices come down as well. Over all I’m pretty stoked on it
Yeah, I'm waiting until they release their new hotness, I believe called "ObXidian", which is indestructible, but apparently prints like brass. Multi-material, with diamond-like coating, and non-stick, etc. Looks great. When I can buy those, I'll get a Revo.
Damn! Thanks for that info. I will most definitely be getting one of those ASAP as well.
Or look at the Dragon and keep access to all the v6 nozzles.
Getting rid of the V6 nozzles is an actual goal for me. Swapping nozzles with this system is a pain in the ass, so I rarely do.
This is a hotend problem, not a nozzle problem.
Partsbuilt 3D carries genuine Prusa parts. I bought a Buddy Board from them a couple weeks ago- fast shipping.
Thanks
E3D does sell the prusa hotend kits directly too and you may be able to buy them from a local official reseller, like filastruder
thanks
I just got a thermistor on Amazon.
