I'm wondering if (and how much) this kind of nozzle extrudes material of more uniform temperature, and whether this has an effect on the mechanical properties of the parts, even when not doing high-volume printing. I can well imagine that at the top end of performance of a standard nozzle the inner part of the flow is markedly colder than the part of the flow closer to the nozzle walls, causing internal stresses or even cracks. It might be the case that these nozzles not only allow you to print faster, but also produce stronger parts.
@MatthewBallinger2 жыл бұрын
Agreed. Most of my prints are functional prints. Printing with a larger nozzle alone makes a huge difference in layer adhesion. My default is now 0.6mm and I was thinking of going to a 0.8mm. Now it's a no brainer. I can't wait for these to arrive!

Mill a slot in the nozzle with a width:height ratio of about 3:1. This appears to avoid the claims of the patent; should give equivalent improved heat transfer, and should be easier to clean when cold. For the deluxe version, drill two holes on either side of the milled slot and fill them with silver ( the most heat conductive metal ) Use these ideas in combination with the volcano idea with the long nozzle which gives more time in contact with the heating source for a given speed, and cover the whole thing in an insulating sock.

Patents put a lot of power in the hands of the patent holder and are more often used for market control than the protection of ideas.

Even for situations where the printer has some headroom before hitting extrusion limits, according to the charts these nozzles help keep performance consistent over a wider operating range. I wouldn't be surprised if these could help print quality even at medium-fast settings. Even with my prusa mk3, I get very close to extrusion limits on a 0.6mm nozzle when printing infill, as I usually tune infill to print as fast as possible. I have noticed with petg the infill can stop printing correctly, so perhaps these nozzles would help.

It doesn’t restrain flow because its hot and it splits up the material using a tri blade wedge. This actually prevents clogging by breaking down the filament faster and having an anti clogging effect thats similar to a log splitter. When a log splitter presses a log through one half goes each way juts like a tri blade splits it in 1/3rds, or a 4 blade into 1/4’s. This process takes less effort and in turn less likely to have clogs or filament jamming. This assumes that your equipment is also complimentary but it doesn’t disregard some of the quirks of a 3 inlet design that are overcome by a 4 core design. Length of nozzle also matters. Some designs are not welcome for all printer extruders without further engineering. I designed my own nozzles several years ago with a unique extruder design I machined on my CNC and it uses a quad core design with a different core material and this allows finer tip nozzles to be used at higher speeds for greater flow and print detail. This also allows filaments like ninja flex to work in a Bowden.

In fact I have worse outcome than on regular nozzle that costs me 1/10 of CHT, even on max-tighten screw for extruder spring. To be ohnest - bi-metal heatbreak didn't improve flowrate that much as I was expecting either.

I got a 1mm one in the post :). Combined with a Dragon high flow that should be good fun printing vases. I just read trough the patent a think they omitted an important part: you can make this same structure in the bottom part of an all metal heat break and achieve the same. For instance a high flow Dragon or Mosquito Magnum could get it and up their flow capability to super volcano levels. The standard flow Dragon or Mosquito probably can reach volcano performance this way. And when combining the CHT nozzle with "CHT Dragon" or "CHT Mosquito" maybe even a standard all metal hotend gets near to super volcano capabilities. Another advantage I see is that the heater block can be run at lower temperature as the plastic is anyway molten better/more homogeneously. This will deliver more consistent extrusion and I would not be surprised stronger parts too as the infill bits that are typically printed faster will be molten better and thus give better layer bonding - Do I see a future CNC Kitchen review? :) -

While the core might not directly conduct heat into the plastic, they increase flow rate near the walls of the heat transferring outside surfaces. Liquid cooling radiators try to increase shear rate near the walls to accelerate heat transfer, which is the closest engineering example I can think of. Very clever design and I want to get my hands on one! $20 is pretty reasonable. I wonder if a copper version will be released.

Wow, I usually respect CNC Kitchens work most for the discipline he shows. I think the material tests are outstanding and the go-to address if research for materials for FDM printers is needed. This time I really liked the reverse engineering of the concept, which went into the design. However, I wondered how splitting the material works as well, if it might be relatively hard at that point. Does it mean, that getting it to soften is easy, but getting it hot enough to squeeze through a tiny hole is the hard part? Then, the concept should have an even bigger advantage for smaller nozzles, shouldn't it? P.S.: Sometimes I really like some of his innovations, too. However, it always seems, that solid engineering is his strong point.

My idea: I thought that one would not need a Volcano nozzle for a Volcano hotend, if one would make an insert into the heater block, which covers the half of the length, then you could use just regular V6 nozzles for Volcano. The plastic wouldn't care whether the insert part or the nozzle part heats it up, the nozzle is just required because of the precision orifice at it's tip. Improving it even further, based on this nozzle, one could make a cloverleaf insert for a Volcano hotend, the still use the standard V6 nozzle. Benefits: - no need to manufacture cloverleaf into a nozzle you throw away when the orifice is worn out, and the internal cloverleaf insert would last longer. - one could use any existing V6 style nozzle, with special coatings, Ruby tip, etc, while benefiting from better performance.

It's routinely used on the heatbreak (COLD SIDE ONLY). I specifically contacted Artic (who makes thermal paste for CPU's) and one of their engineers told me to use MX-4 but suggested that breakdown would occur if used on the HOT parts (although specs show it's breakdown point above 'normal' 3D print temps, but not high temp stuff like PC). It's generally not recommended to use on nozzles or the hot part of the the heatbreaks, it could cause galling of the threads and prevent removal. That said, I'd LOVE to see this researched more!!
@duediligence791 Жыл бұрын
It doesn’t restrain flow because its hot and it splits up the material using a tri blade wedge. This actually prevents clogging by breaking the down the filament faster and having an anti clogging effect thats similar to a log splitter. When a log splitter presses a log through one half goes each way juts like a tri blade splits it in 1/3rds, or a 4 blade into 1/4’s. This process takes less effort and in turn less likely to have clogs or filament jamming. This assumes that the teat of your equipment is also complimentary.

In other words: 1. If you already have a Volcano, the CHT nozzle won't help. 2. If you don't have a 40W heater, the CHT nozzle won't help. 3. If you DON'T have a Volcano, and DO have a 40W heater, the CHT nozzle will let you use MUCH higher extrusion rates! But clearing the nozzle could be a problem.

After seeing your review here, I was so intrigued I ordered it immediately. I saw it in early Januar this year and received it late January. Today, I just installed it and wow... you say: "Will this become the new standard for how 3D printing nozzles will look? I'm quite sure, no..." -- I don't disagree with your reasoning, but I will say that it SHOULD be. I have a fairly fast delta printer with a crappy E3D V6 clone hotend, which due to the delta bed, isn't easy to change with something larger such as the Volcano hotend. With E3D Nozzle X, my printer can actually only deliver 9 mm2/s. Which is a sad and low number, and it does become an issue in print jobs with no traveling, i.e. continous extrusion - such as in vase mode. My printer can easily go 120 mm/s reliably with 5500 mm/s acceleration and 25 mm/s jerk. But with either the standard brass nozzles or the E3D nozzle X, I need to go down to 70 mm/s in vase mode (continous extrusion). Today I've begun testing the CHT nozzle (0.4mm) - fitted on my delta printer without any modifications. Just a nozzle swap. At 15 mm/s2 volumetric speed, I go at around 130 mm/s and I can probably go even higher. That's amazing - because now I can print my vases with 0.58mm width and 0.2mm layer height at 130-140 mm/s, without the walls getting thinner or having holes in them. I could of course also try the 0.6mm CHT nozzle and see if I can still go that fast, but I print a lot of different things, so the 0.4mm is a nice size for me; I can do fairly detailed stuff with high surface quality at around 100-120 mm/s, or I can ramp up the print speed to 130-140 mm/s and have fast drafts. Well, actually the CHT delivers quite high quality in my vase mode tests at 130 mm/s so yeah, I'm a VERY happy camper. Even slower printers would benefit with the higher output, because eventually, people will want to print faster and modern printers are more likely to come with solid movement systems and solid frames that can withstand speeds at over 100 mm/s easily, even cartesian printers can go this high now - and with CoreXY becoming more used, much faster prints are possible. I don't mind paying the premium price for this nozzle; it's not worn down easily according to specs, so it's not like I need to change it as often as brass nozzles. Now I just have to hope that my extruder stepper motor won't overheat, because it's obviously working overtime ^_^
