I've known Max for 3 years and he is always like this so - excited and knowledgeable. I have 4 APUS extruders and 2 XG hot ends will be excited when the new version of the XG is ready for sale. One concern I have had is parts availability. I have purchased all of my units from Fabreko who has been great to work with, but doesn't sell replacement heaters - etc, at least yet.

[@NathanBuildsRobots]

I like how he answered all my questions like “well, yes, but no”. Definitely cares about the minutia, which is important in product design. I didn’t realize it was so easy to clear out the filament path on the APUS. I have one but haven’t installed it on anything, but after hearing him explain how it works, it actually seems like it would be very nice to use. More focused on usability than weight or compactness. Most extruders, if you get a jam take 20 minutes to take apart and clear, to the point where I don’t even bother with flexibles. This, and the NG from Microswiss, look like they are actually designed for someone to use them.

[@woodwaker1]

@@NathanBuildsRobots I have had good results with the APUS and XG combination on my Rat Rigs. It is a straight shot from the APUS to the nozzle if I have a jam I can usually use my unclogger to go all the way down and force it out. Worst case is to take the XG out via the screws on the EVA mount, takes about 5 minutes.

[@Phaetus3D]

Thank you for your support. Fabreeko has become our after sales service centre in the USA. They already got some of the parts for replacement, and would have more in the future.😀

[@ThantiK]

That dark purple rapido looks fire. This is basically the same system that the bambu uses on the X1C for their heating, and really I'm concerned with the effect regarding heat only on one side of the block like that. The benefit to the cylindrical ceramic heaters was even heating all around the filament. Unfortunately this is incredibly hard to measure in terms of the thermal effect. Filament itself acts like its own heatsink, sapping heat away from the center core of the block. When you have heat only emanating from one surface of that block, you're going to get a reduction in overall melt volume. I'd like to see this with the same setup, but with dual ceramic heaters maybe in series and sold as a pair but some empirical testing could easily convince me that single sided heating is fine. Likely I'll be moving to an LSD/Goliath hot end from Vez/Mellow soon anyhow, but the Phaetus Rapido UHF has been my go to for a long time, and it's been ultimately reliable and a joy to work with. Really sad that Slice have done their best to keep competition out of this space, even going so far as to threaten Vez/Mellow with regards to the Goliath. I'll continue purchasing Phaetus and others and #NeverSlice.

[@jamessunday6668]

I have a large 24v battery to utilize for my diy printer. I was wondering if I could use a 24v flat ceramic heater like the x1c uses but on two sides. I'm not sure why that would be necessary since I won't be printing super fast.

[@DigBickMcQueen]

I believe that the area the heater is responsible for is small enough that the disparity between the heater and its opposing side are negligible. Also, keep in mind that we don’t really care about the uniformity in heating of the ENTIRE heatblock. We only care about the area that filament goes through and touches. This means that any effect caused by temperature disparity becomes even more negligible. However I’m sure that if we were to scale up the heater and heatblock we would start seeing the results that you alluded to and circular ceramic hotends would have a clear advantage.

All of this is so yesterday. Only good thing is 3 point rigid heatblock frame. If you need volumetric performance is just a goliath / supervolcano / volcano + extenders. Future is thermal advance algorhytms + low thermal mass high power hotends. E.g. hardened steel volcano-like nozzles in ceramic isolator + induction heater.

[@Leviathan3DPrinting]

Awesome! I've been wanting to know more about the 2.0 since they teased it. Thanks Nathan!

[@NathanBuildsRobots]

No problem! Looks like a solid improvement. Same form factor but more serviceable.

[@Leviathan3DPrinting]

So they added a bambu labs hotside to a rapido lol.

[@Leviathan3DPrinting]

@@NathanBuildsRobots Did they fix the issue with the screws that secure the heater? if you over torque the 3 screws it will compress the top of the heatbreak causing it to not feed filament until you manually reopen the top with a screwdriver or something. I personally never had a heater die on mine in almost 2 years. Other than that one issue (really user error) it's honestly very solid and I'm sure the new release will be equally as well made.

[@NathanBuildsRobots]

He explained the kinematic coupling to me. I can see that being an issue. But using spacers is off the table unless you want to license that from slice engineering. Best to just be careful when torquing things down.

[@NathanBuildsRobots]

The flat ceramic heater is a cheaper solution, and probably saves a lot of time and money in QC. It’s a step in the right direction. The thermistor is screwed in place instead of the bambu method of just kind of glooping it in place with thermal compound.

[@Pugwash.]

I NEED A PINK HOTEND PLS

[@Liberty4Ever]

I wish the engineering that goes into high end parts such as extruders and nozzles, the very heart of a 3D printer, was being done by the high volume 3D printer manufacturers. We have mass produced printers with ten year old technology, and we have high tech innovation at the bleeding edge that very slowly migrates to the mass market. We need a lot more engineering done by volume manufacturers to get the bugs worked out sooner and the cost reduced.

[@NathanBuildsRobots]

Mass produced designs are optimized to reduce cost, not to maximize performance

[@Liberty4Ever]

@@NathanBuildsRobots - Recent mass produced 3D printers with print speeds over 400 mm/s need higher performance hotends and while it does look like the manufacturers put some effort into the designs (and borrowed heavily from the custom high performance hotends developed in the 3D printer hot rod aftermarket), it seems that Creality didn't quite finalize the K1's hotend design in time for shipping. I don't expect purple anodizing or tungsten carbide on a $600 printer with all of the features of the K1, but I do expect a cost reduced hotend to work without wiring parts to keep them in place, and to last more than a month.

[@NavySturmGewehr]

Why isn't the hot end induction heated? Then the heater itself can also report the temperature.

[@NathanBuildsRobots]

Induction heaters are expensive can cause EM interference, and have unpredictable failure modes. At least, I think that is the case. You can use any old heater as a temperature sensor, but I think it’s just cheaper or easier to use a thermistor

[@leeo.alexander2324]

This is just a general question. I have an two printers, Artillery Sidewider X1 and a Flsun Q5. Which hotend would be a good upgrade for either printer; for fitment and functionality?

[@NathanBuildsRobots]

I’d do the X1. It’s the more capable machine, but modding it will be. A pretty involved process where you rework the whole toolhead

[@Rievven]

[@kiddkai]

[@NathanBuildsRobots]

Nothing gets past the YT comments section! www.fusrock.com/index.php/nexpa-gf25/# You’re right, it does look similar. Lots of these 3D printing technologies are developed, licensed, and distributed in a network of companies.

[@ga6287]

I only have 2 printers and all these hotends make me want to try them lol

[@NathanBuildsRobots]

Yeah, they really look great. I’d stick with the best seller, the rapido with tungsten nozzle. That is the only hotend I’ve bothered to take off another printer and install onto a new one because I like it so much.

[@ga6287]

I recently got that one and love the performance. Want to grab it for my second printer. My only question is that, is cross compatible with the original raptito in terms of bolt/hole pattern. If so, that's really nice.

[@NathanBuildsRobots]

[@jezzayang749]

Could you mod the Creality K1 with one of these nozzles? Because I feel like it would massively improve the performance of the Creality k1 since its stock nozzle is not very good.

[@NathanBuildsRobots]

You 100% could. I have a bimetallic volcano CHT, which is another great option. Only caveat is if your bed is super uneven it can cause issues with the shorter nozzle. But it should be fine, and if switching to a normal geometry volcano nozzle causes issues you need to manually level the bed anyways

bare metal if it costs less. i can't see the heatsink anyway, i rather have a cheaper one if it is just as effective

[@leeroyjenkins7915]

color anodizing a large batch at once costs barely nothing nowadays. In fact, even most "bare" metals (aluminium) are anodized anyway, because anodizing also gives the metal a protective coating

[@free_spirit1]

I always wonder about the financial viability of these companies. How many people are building their own printers? How many Vorons have been made world wide? I can't imagine it is more than a few thousand at most. That's not a lot of hotends. Same goes for bigger players. With E3D and nozzles for instance: Prusa pridefully announced a few years back they had made 100.000 printers. That's not that many printers really. So if you're E3D and you have the supply contract for those nozzles and you make 3€ per nozzle, that really is not a lot of money at the end of the day. Am I making any mistakes in my thought process here?

[@NathanBuildsRobots]

The stuff costs close to nothing to manufacture if done properly. Not a whole lot of design hrs go into the products, idk it ends up making a good deal of $$$ if you sell 10-30k of them

Will there be some kind of upgrade path or compatility for existing XG hotends? I'd love to be able to upgrade to neXtG without outright replacing the whole thing.

[@DropEffect]

We wanted to design the neXt G in such a way that an upgrade kit would be possible. The Problem was that we had to do some many changes to the architecture so that the hotend could support V6 nozzles and also we did want to increase the size of the hotend but instead decrease and still make a high-flow nozzle. I am really sorry that we did not manage to give the XG users the possibility to easily upgrade :(

[@alicec2033]

@@DropEffect I see, I guess with extensive redesigning that's understandable; thank you for the reply. Just being completely sure, but if I purchased the neXtG heat block, I wouldn't be able to screw it into my existing XG hotends? My main concern is that I'd really like to use some of my nicer V6 nozzles again on my XG.

[@Auggie246]

[@wehavefun3433]

Hopefully they resolve the fragility issues with the Rapido. I’ve lost several to attempting to change the nozzle, and having the whole ceramic part break apart, or the thin wire contacts coming off. Seriously, I think I’ve had 6 or 7 fail me now. Great at extruding, not great at staying alive and working. 👎

why dont you use watercooling for the heatbrake? maybe i am 10 years ahead.

[@skybldev]

some hotends already do that; see goliath

[@NathanBuildsRobots]

Leaking is the biggest concern. We’re not cooling a power plant here, just 1-3 watts of residual heat that makes it past the heatbreak.

[@ThantiK]

Many people who build for enclosed chambers do water cool for this very reason. It's hard to thermally transfer heat out of the hot end when the air around it is ALSO at 80C.

[@AndrewAHayes]

@@NathanBuildsRobots Yeah an adequate fan is all that is needed, watercooling is like taking a sledgehammer to knock in a pin.

[@NathanBuildsRobots]

90% of the time I see a water cooled build it’s on an unenclosed Ender 3, just 1 loose fitting away from being in your repair shop 😭 But yes, in heated chambers that is an exceptional use case. Personally I might just run an air loop if it were my printer, to avoid risk of damaging a likely thousands of dollar printer with high powered bed, chambers, high temp steppers, etc.

Or use some surface layer thermally conductive witchcraft like the new positron is using.

I bought some to see if I can slap them on other machines too. Seems like a fun experiment.

[@NathanBuildsRobots]

It’s not a total copy though. Heatbreak, kinematic coupling, V6 nozzle compatibility, and thermistor integration are all differences. Yes the one element is the same. But the rest is different. Additionally it’s compatible with all of the previous mounts designed for the V6, dragon, and Rapido 1.0 If you fixated on one aspect of the design, and the heating element is all that matters to you, then yes, it’s totally a copy. But even then if you look close enough at the heating element and how it’s secured, you might find some differences (improvement even). And I can pretty much guarantee that this can extruder higher flow rates than the bambu lab extruder and withstand crashes without breaking as easily as the bambu extruder. Progress is progress, even if it looks the same to you.
