Anyone seen the new haldis k1 hf hotend?
-
Noticed it when surfing AliExpress the other day. Looks like a e3d revo had sex with a mosquito. Pretty impressive looking. Wonder how long until they are forced to stop making them by e3d/slice patents?
-
@breed That doesn't have the quick change nozzle/heatbreak the revo has, the photos show the coldend as part of the heatbreak/nozzle.
-
@stephen6309 threads in at heater instead of coldend. Heater is supported like on a mosquito, much less chance of a bent/broken heatbreak throat. No heatbreak->nozzle joint to leak. Just as easy to machine a copper heat sink as it is to machine copper threads. Seems to be superior design to both the mosquito and the Revo.

For anyone who hasn't seen it:
https://www.amazon.com/Haldis-3D-Red-Lizard-Hotend/dp/B09HGDDZ26?th=1It looks pretty good to me, but I'd have to try it to be sure. No fan????

@mrehorstdmd That's different one. https://www.aliexpress.com/item/1005003839228285.html

@stephen6309 that's the one. If they come out with a hardened nozzle I'll be sold. Tungsten would be awesome.

recieved one from china today. its pretty impressive. Definitly nicer than a rapido. 115w heater. i like how the Nozzle/break/heatsink threads at the bottom of the heater.

That's what the documentation says I haven't checked the amperage.
-
@breed I couldn't see any mention of the temperature sensor on the ali express page. What does it come with?
I don't understand- they tout it as a high flow hot-end but the only nozzle available is 0.4 mm.
I see spare nozzles for sale (all 0.4mm), but no spare heater and no spare temperature sensor.
-
@mrehorstdmd they have .4 .6 .8mm nozzles, the metal block, heater, and temp sensor in the haldis store on AliExpress. Their documentation is a little lacking but the thing seems to be a unit. I have one in hand now and was comparing it to a Pheatus Rapido, it seems to be just as well made. If the nozzle/break/sink gets made in a hardened version at some point, I think it will be a winner. I'm not sure what kind of sensor it is, assuming it's just a thermistor. Haven't had time to test it yet. Printed an adapter to mount it on a smart effector on one of my predators, but it's spring now, not much time to tinker.

@breed Oh, I see. It comes with a 0.4 mm nozzle and you can buy the others separately. They never mention the type of sensor- if it's a thermistor you're not going to be able to use it for real high temperature printing- you'll be limited to ABS, which is OK for most people, but they are specifically promoting it as a super high temperature hot-end. Hmmm. Maybe they'll come out with a PT100 or thermocouple sensor that fits in the available space.
-
@mrehorstdmd I think they are just saying the coated copper block can handle high temp. Prob just because they seen other companies saying coated copper blocks for high temp. It would be nice if they would at least mention what kind it is.
-
@phaedrux it's a PTC heater, so it will draw about 60W when at 200C and a bit less above that.
-
I'll try and connect it this week and see how many watts it pulls.
