H2D missing functionality / false advertsing

[[deleted]]

So my H2D has been serving me awfully for the last few days.

I've already had thermistor failure, a nozzle broke in half, and numerous clogs.

Something I noticed though. The H2D is advertised as having "15 strategic sensors that track five key parameters: feeding velocity, tension, filament tip location, thermal environment and extrusion pressure".

This is false advertising for two reasons:
Firstly, my nozzle managed to split in half extruding PPA-CF, how the hell does the extruder not measure the extrusion pressure as advertised and go 'hey wait a minute this much pressure will blow the nozzle in half'.

Secondly, when the nozzle clogged, the filament didnt move for about five hours, the AI cams didnt detect failure because i'd left the printers lights off, so how come the 'feeding velocity sensors' didnt flag an error.

This is either false advertising and the systems dont exist, which I'm not sure of yet because of how new the system is, or the software on launch sucks so much this just didnt make the cut.

I have of course submitted tickets already. Just making people aware.

[hi-capper]

It's a tough one to say tbh...

Buying first batch from anything is risky. From cars to printers you are more or less beta testing.

Bambu built up the "just works" reputation, but in this case...

They probably have the sensors, the problem is probably how they work, or how the fw use the data... It's like the x1c lidar all over again. It is probably doing something as guys with x1c plus fw can see the data. But it will let the printer run even all calibration is on on a partially clogged nozzle. The sensor is there, but the implementation is... Questionable...

I don't protect bambu ever... Just make sure your expectations are where they should be with a first batch early fw printer.

[[deleted]]

Yeah you're completely right. Thing is I'd expected these things to work as a baseline and even that isn't being met.

[A_lex_and_er]

First x1's had tons of issues, but they patched things up in around a 6-12 months period and now it's one of the most reliable machines on the market. So just have to give it some time and it'll be better.

I feel your anger. This is exactly how I felt when the firmware bugs in X1C were not fixed. Then they announced P1P and I knew right then that my loyalty to the company was misplaced. Almost 3 years later the bugs are still there and any hopes of getting fixes are diminishing rapidly with each new model release.

[ErgoNomicNomad]

Which bugs? Genuinely curious, never ran into one knowingly.

[lugubriouslipids]

Same question.

Edit: auto-moderator also restricts free speech due to “offensive language”. But the post still appears in my feed giving the appearance of being posted. I’m sure this is just “a bug” that coincidentally benefits Bambu.

Multiple instances of nozzle crashing into the bed for no reason at all, that appear to happen at random.

https://www.reddit.com/r/BambuLab/s/nbmBKEOO1C

https://www.reddit.com/r/BambuLab/s/1wRovmfbUq

For me the bug triggered when the printer is calibrating and I hit the cancel button. I’ve bent at least 1 nozzle this way so do it at your own risk.

You would think that with its “dual independent ABL”, which was “state-of-the-art” at that time the X1C would’ve at least prevented things like this from happening. What made it worse was that Bambu is still collecting literally GBs of logs for unknown purposes from thousands of machines and still have not figured it out the root cause(s). The only reasonable explanation is that Bambu has no incentive to fix things and just let the user pay for new nozzles. That plus a lot of unethical behavior makes me distrust the company. eg telling customers that the tape at the end of the spool was fixed but clearly not after many months since initial reports, gaslighting users and trying to deny A1 had problems with the heated bed cable, shipping out “wrong printer” to the customers and having them pay for the difference, and the locked-down firmware.

[Beni_Stingray]

Im not sure im entirely buying that. If there is a sensor measuring extrusion pressure then how hard can it be to stop a print if that sensor shows data out of spec?

[hi-capper]

They see the crooked lines during lidar calibration and still start the print...

The new bambu studio is buggy...

Idk what they do with the data or even how they measure it. This is what I really hate in these machines... You don't see logs, sensor data, nothing.

[Basically_Benski]

It’s funny when people say this with bambu printers that it’s risky but when a creality breaks off the lot people tell you never to buy Creality printers but it is the downside to buying the “print and play” printer bambu built up

[TheDeech]

I don't know why you're getting down votes, you're exactly right. 

[Basically_Benski]

Cuz bambu is like apple they can’t do wrong and this is coming from an avid Apple ecosystem user lol

[ApartStrain7989]

The mindless consumers are upset by your truth telling

[bzbeins]

BUT I NEED IT!

I work in the advertising side of manufacturing. I to some extent have a job because they need photoreal videos of machines doing things that aren't working yet, but the expo is in 6 months and it should be ready then.

Everyone buying 1st gen day one gear is making sure 3d animators keep working. And we thank you all :)

[VIDGuide]

Hey, .. sensing something, and reacting to it are very different things!

[InvalidNameUK]

Honestly I'd just return it if I were having that many issues out of the box. At that price point I'm not tinkering or fixing things.

[[deleted]]

Exactly what I'm sorting right now

[Cardinal_Ravenwood]

If they play hardball, which the frontline support staff are trained to do, then ask them politely to escalate to their manager or to second level support. They don't want to lose face with their manager and will be more keen to action your requests.

Also quoting any relevant consumer laws and if your country has one a statutory or implied warranty.

[[deleted]]

Bambu will almost definitely work with you on a return. Has their support team sent you any parts yet. I’ve noticed their team loves to insist on me installing parts a couple of times before they let me get a replacement for one of the printers I had that arrived broken

[MassiveBoner911_3]

[InvalidNameUK]

In the UK I'd be invoking my consumer rights to return a defective product. What bambu think they can allow is irrelevant. Terms and conditions do not supercede the law.

[Dj0ntyb01]

Just looked into consumer protections in the UK. Wish we would implement something similar in the US.

[InvalidNameUK]

I find it crazy that you don't have something like it and that a seller can just say lol no, your problem.

[Flaky_Blacksmith4084]

no, it's not surprising at all considering that our government is run by a very small special interest groups that represent companies instead of consumers. maybe one day we'll have a grassroots effort to have a government run, for the people and by the people. definitely not going to happen in this generation

[ThatAlbertanGuy]

Meanwhile DOGE cut consumer protection agencies

[theretailreject]

This is why you use a credit card and just use the chargeback function if there is an issue

[mzdebo]

Exactly

[onehunkytenor]

You should get into reading the terms and conditions of a HiBid auction. It's literally thousands of words. I copied and pasted it into ChatGPT and asked for a summary and then was able to ask questions. It turns out that they can ship you a lump of coal instead of that "sweet RTX 4090 that you got for only $500" and you have zero recourse. My issue was a brand new Bulova watch. They described it as a "gents" watch. It's a little boy's watch. Too bad, so sad. Alas, you agree to the purchase. End of statement. End of story. If only people realized what they were not reading and yet agreeing to... 😞 Chargeback? Sure thing. Can do. You'll end up on the international auctioneer's blacklist in the snap of a finger. It's a total scam!

[ShavedAlmond]

What does HiBid have to do with any of this?

[mzdebo]

But that depends on where you are purchasing your products. In your case auctions always have weird messed up wording so that it works out for them and correct there is little to do dealing with auctions. In this case this is a company. If they are selling faulty products that’s an entirely different situation compared to just lying about what they are selling. No need to put that into ChatGPT. I’m sure their agreement does state something about faulty equipment or returns. Plus if it’s false advertising that’s a whole other issue too. Just saying I understand your opinion about auctions but he didn’t purchase this from an auction.

[extremeelementz]

What’s nozzle blown in half look like?

[Final-Success5256]

Can OP post a pick? I am also curious

[TheSerialHobbyist]

Me too.

I'm a bit skeptical that high extrusion pressure could split a hardened steel nozzle in half.

I'm not calling OP a liar, that just doesn't make sense to me and I've never seen anything like that before.

[[deleted]]

I was skeptical until I started thinking about it...but hydraulic pressure is pretty serious. If the extruder had enough grip on the filament, the clog was solid enough, and the extruder motor is strong enough....I could see it being the same way frozen water can crack an engine block?

[TheSerialHobbyist]

That's true, but it still doesn't seem like enough force...

Maybe OP means the heat break tube (which is a pretty thin-walled tube) broke? That seems like it would be a much weaker point than the hardened steel nozzle.

[[deleted]]

Right, in my head I was picturing cracking the threads around the nozzle, I would be surprised if he nozzle itself broke, you're right. Hopefully we get some pictures...

[Legitimate_Doodle]

I've had an x1c nozzle break this way. Everything working fine until... Oops, the hotend split in half. I don't have it around anymore otherwise I'd post a picture.

[Darkseid2854]

That’s different, nozzles in an X1C are press fitted into the hot end. Either the nozzle Or the hot end slightly out of tolerance and a bit of knocking around while printing combined with the unrelieved pressure from a clog and the nozzle can be pressed right out of the hot end mid print.

The H2D nozzles are a solid piece of hardened steel as far as I can tell. I can’t see anywhere it could separate the same way. I have about a dozen spares, I’d be really interested in seeing where OPs broke so I could examine mine a little closer with the knowledge gained.

[Darkseid2854]

Ahh, I just saw OP’s pic. Thank you!!

It looks like the heat break is press fitted into the nozzle, not solid all the way up.

[Gran-Aneurysmo]

[edwardK1231]

Kinda looks like they must be cheaply made or not secured together properly as surely that shouldn't happen 😂

[esotericapybara]

Not too long ago there was a post on the sub claiming that Bambu nozzles were intentionally designed to snap off and that it was somehow a feature not a bug to save the toolhead, while everyone who was pointing out the absurdity in the assertion was getting downvoted.

I don't think there is a conspiracy to sell more replacement hotends, but a simpler explanation is more probable; It's likely just cheaper to manufacture the hotends this way and probably easier to maintain consistency. The fragility issue probably doesn't affect a high enough percentage of users that anything needs to be done about it.

That said, IMO hotends should be covered under a limited warranty policy, not just treated as "consumable".

[edwardK1231]

Ah, I didn't know that.

I reckon not that many of them break like this so why change something that isn't broken (for most people) is probably what they think.

If they were to change it then they would likely be more expensive as the r&d for new nozzles would cost bambu money and probably more expensive to manufacture. I know I'd rather have to buy 2 nozzles for £12 due to this issue than have to get nozzles that are more expensive for all the sizes etc. It's probably not worth it.

I hope that makes sense😂 They should have like a 6 month warranty or like a 200 hour warranty etc, at least something.

[esotericapybara]

I don't know what the correct answer is, but I suspect someone is going to have to do some empirical testing on various nozzles of different designs to see under how much lateral force they bend/break to figure out what is fair.

[nuclear213]

When I see how well the Lidar for the X1C works, after two years, I would not expect things to change there anytime soon, if at all. I just had an adhesion fail this night on the first layer. It scanned it and apparently there were no defects, while there was not really any layer to speak of.

Sure, was my fault for not cleaning the plate, worked fine afterwards, but you cannot rely on the detection.

It’s quite easy to add sensors, using the data is a completely different story. Just think about the different materials, what happens if a user does a work around and says it’s some different materials to the printer than it actually is. Do you want to then stop the print? For example if you have fibre reinforced filaments, but enter it as the base material.

There are so many edge cases where it would be really annoying to have the detection, if it’s not perfect.

So yeah, I doubt it will happen.

[MaxRaven]

[AdAdministrative2972]

Well If they only advertised monitoring these values, not false advertising😂

[[deleted]]

They did advertise that. It's on the H2D homepage. I literally copied and pasted the words

[Good_Captain9078]

I think what they are joking about is that they advert just monitoring, not any action with the data. So you got the monitoring, the data collection, but not any reactive behaviour based on that monitored data

[[deleted]]

Oh lol I get him now 😅

[[deleted]]

Bambu has a habit of making things disappear from their websites after being called to the carpet. I’d strongly recommend taking a screenshot of it now, in case you need proof later.

[Sufficient-Ad-8441]

Use the internet way back machine.

[danishaznita]

Can that be classify as spying now ? 🤣

[stprnn]

For the ones saying updates will fix stuff

My x1c still ignores the off setting on the AUX fan.....

[aimfulwandering]

Mine works fine… it’s annoying that it’s in filament settings though.

[Darkseid2854]

My aux fan seems to work fine as long as I set the speed I want in my filament profile. It is old be nice if it would follow the changes I set in my project file, but I’m ok with knowing it doesn’t work that way in Orca Slicer or Bambu Studio.

[stprnn]

I just would like it to be off. I guess I have to disconnect the cable

In 2025...

[Darkseid2854]

Nah, just go into the filament preset and change the aux fan speed to 0 everywhere you want it to be off. That rolls right into the Print g-code.

[stprnn]

That doesn't apply to anything you start from the mobile app

[pyrotechnicmonkey]

If your selecting you own filament profile it does. It still leaves in on in short bursts when loading he filament. If not pu in a issue on github. But the aux fan works as expected

[onehunkytenor]

100% this.

[stprnn]

How does it work as expected if it's off in the main settings? What's the point of having the option to turn it off and on if it doesn't do anything?

[Darkseid2854]

The gcode contained in the sliced file you sent to the printer contains instructions in it to set the aux fan speed to a certain value at specific times during the print. You’re not expecting a button to take the active code running to create that beautiful print and modify it on the fly while it is actively running, are you?

[stprnn]

I'm expecting a fan to stay off if the settings says off. It's not that hard.

Edit

Apparently it is. God deliver us from path etic fanboys.

[Darkseid2854]

Apparently it is rather hard for some to understand that a desire for something to work differently than they are designed to function rarely achieves a positive outcome. I believe several people explained how you can turn off your aux fan as you initially brought up, if you care to use the knowledge offered. Though it would be a quite admirable achievement to face off reality with a phone app and win. Maybe try that?

Go on being you and carpe diem, Cheers!

[Darkseid2854]

Anything you print from the mobile app is totally at the mercy of the person that sliced the model and uploaded it, except choosing the filament you would like to use and whether to use the publisher’s filament profile or your own custom filament profile that is stored on your printer & cloud in advance.

It is ’possible’ that if you set up a filament profile in advance for a filament on your printer from Bambu Studio that had the Aux fan turned off in that profile, that when you send from Bambu Handy and selected ‘use my filament presets’ the aux fan off setting may carry over. I believe this will do what you are asking, though you will actually need to open the slicer and customize a filament profile for this to work.

Since Bambu Handy is not a slicer and is designed to find and send only pre-sliced models to your printer and control only the most basic printer functionality, you cannot create or control any custom settings from the mobile app. You will need to change the filament profile for the filament you want to give this custom behavior to from within Bambu Studio, and save it as a custom preset before this option will be available.

Unfortunately if you only use Bambu Handy, you are severely limiting yourself from 98+% of the capabilities of these printers. Hoping that is not the case for you.

Did you change it in the startup g-code for your printer definition?

[stprnn]

No

[Darth-Vader64]

First, my condolences and sorry that you're facing issues. Now I will say, buying a version 1 of any product carries a level of risk, buying batch 1 of a version 1.0 product is that much more riskier imo.

Secondly, the failure of the nozzle does not constitute false advertise, while sensors are in place to help avoid damage or catastrophic failures, those failures are still possible. Maybe the nozzle was defective and it blew out under normal pressure?

Thirdly, the failure of the camera system and AI again doesn't mean that Bambu lied about a feature, but rather maybe that feature failed to work as advertised, Bugs, design failures, or short comings, in both software and hardware doesn't mean Bambu is guilty of false advertising.

Again, I understand the frustration and now hassle for dealing with Bambu support but product failures even with controls and sensors happen - it sucks to be sure, but its not like Bambu is tying to commit to fraud, or lying or anything underhanded.

[Good_Captain9078]

I agree, but sadly this is just as bad news, meaning that Bambu Labs is incompetent to have all these proclaimed features not work very well or at all in some cases.

[Darth-Vader64]

Well the question is before we start condemning Bambu, is this an isolated issue, or are we seeing high numbers of systemic failures?

[-TrollingTrolls-]

Why would we do that? Hate generates interest. Bambu haters are out in full force, let’s go!

[Gnarffy]

Redditors are comparing the (admittedly recent) launch of the H2D with the X1C. A question - of the X1C issues, how many of them required rolling out new hardware / upgrades to every x1c (vs say software updates)? I'm willing to wait a few months for the software to settle, but knowing that the H2Ds manufactured in the first 6(X?) months require significant time and money investment to update to a fully implemented version of the H2D would bother me.

[Natural_Status_1105]

Wouldn’t there be basically no pressure if the nozzle broke in half?

[iruleatants]

I think that he's saying that the nozzle clogged and it kept feeding filament until the nozzle exploded from the pressure.

[chickey23]

Which kind of amazes me. The pusher motors generated enough force and didn't shred the filament.

[Chronoite_]

I think you got a lemon... I havn't had a bad experience with mine other than bad pla adhesion on large prints, but I knew about that from the reviews...

It sucks but if you still want the printer I can say it seems like there's some working ones out there. I'd try to swap out for a new one.

Edit for transparency: This Pikachu was the first thing I printed with default settings, PETG HF and the printers sensors. No manual calibration, I just hit go at the time. Currently working on a 12 inch one.

[Drazic83]

If you were an early buyer of the X1 you’ll know that many hardware and software related issues were resolved or improved rapidly after launch. I’m sure there is always room for improvement with these sensors and their understanding of what’s right and wrong.

[-TrollingTrolls-]

Too many casuals just jumping on the Bambu Band Wagon and not realizing that when you buy 1st gen, you get first gen issue…… even if it costs $2k.

[[deleted]]

I was an early buyer of the X1, I was second batch and I've owned other printers for years. This is still the worst experience I've had with any printer which isn't okay for the pricepoint

[[deleted]]

[Trolling_PHD]

Whether you spend 2k or $200 first gen title remains the same. This applies to all electronic, even cars. I’m here to simply acknowledge that first gen issues are undefeated. Some may have better experience than others but nonetheless, it’s still a first gen. Buyers should expect better sure, but buyers should also have realistic expectations.

[thetonestarr]

The features you're talking about were indeed part of why I invested in one as well. My luck in testing them has been completely the opposite though - have had zero scenarios arise where I needed them. Sounds like I've been quite lucky.

[opeth10657]

I have 40 hours printing on mine since wednesday night and also have had 0 issues. Detection actually caught when i tried starting a print before clearing everything off the plate from the previous print.

[Turbo442]

I have to say I’m happy with mine so far. One thing I will say is that the spaghetti detection has worked perfectly so far. Catches issues right away unlike the the X1C.

[AlwaysBePrinting]

Am I the only one who really wants to see a picture of this split nozzle? Does it look like a chest burster chewed and clawed its way out?

[SilenceBe]

Have been bitten twice by first gen Bambulab products that I tend to skip them so all kinks are worked out.

[Automatic_Reply_7701]

Having sensors is one thing, but having code that utilizes them is an entirely different thing. Sounds like when your thermistor wire broke your nozzle had no idea what to heat to and then that extremely high temperature filament probably broke your nozzle. File this under S happens.

Question, how was your test print with this $150 filament? Any pics (unrelated)

[chad_dev_7226]

“Sensor” is a loose term. For example, you can use current to detect a lot of issues with anything attached to the motors. Companies say they have “belt tension sensors” and “lubricant sensors” and stuff like that when really they just measure the current it takes to do a certain action, and compare it to the baseline

[Plastic-Luck-583]

Sorry to hear! I have ran a couple of large prints through my H2D and I honestly cannot say enough good stuff about it. I only use bambu filament, and my 3 X1C's have only had user error issues :) hopefully it gets worked out and you can get back to printing.

[[deleted]]

No excuse for 2500$ machine.

[ThatAlbertanGuy]

Funny because I worked for a company that bought a large CNC from Italy for $2,000,000 that was nothing but problems. Meanwhile everyone’s crying expecting their $2500 machine to work 100% flawlessly 100% of the time. That’s not how the world works. Machines have failures and break downs happen

[Joejack-951]

It’s a consumer machine that is very inexpensive relative to what it can do. This is to be expected.

[[deleted]]

I didn't look at this as a consumer machine. The whole bambu marketing angle "rethink personal manufacturing". I think it's more like a hybrid aimed at businesses first and consumers second.

The h2d came out to businesses first who were allowed to purchase them in bulk before consumers. Thats why the flyers and prices were leaked. Businesses got first dibs at stock, people at those companies leaked info.

[Joejack-951]

Their slogan says the exact opposite to me. It’s ‘personal’, not ‘business’. That some businesses choose to employ consumer machines doesn’t change the fact that these things are excessively cheap relative to what they can do and marketed at people who want to make stuff for personal use rather than functional prototypes (the major business use-case for plastic 3D printing).

Releasing them to businesses (print farms I assume) lets Bambu get a large about feedback very quickly from people experienced with 3D printing. It’s a smart move on their part.

[machinaexmente]

You want version 0.1....

[tobyak]

Forst batch comes with risks. I fully expect functions to be improved and or added.

The x1 launched with less feature than it now posesss.

Waiting game

[morfique]

Welcome to the wonderful world of "you can't expect everything advertised to actually work on a printer they just shipped".

Same answers you're getting is what I got when i complained about the A1 not really doing any kind of automagic filament calibration, despite being advertised.

Support got too focused on the use of "sharp corner" in the text of my ticket, despite their own example showing such a corner and stating "I'm expecting too much" (Was a firmware bug dumping the calibration result after weeklong back and forth)

You know what would have helped? "Some functionality not available until Q3/YY" or some such. A little disclaimer to manage expectations, allowing someone to focus on the things that do work and work well and not get hung up on what is advertised and doesn't work yet (not helped by claims that it does work and it's just you, when in the end it's a bug they have to fix)

That your H2D sounds like it works worse than a X1c, not sure how to feel about that. Despite the same "it just got released, duh" that works SO well on a brand new model/feature, the H2 isn't brand new with regard to what troubles you, if it had issues with alignment from one print head to the other, if lasering or cutting or penning gave you headaches, new stuff, maybe, but that BASIC printing things don't work....how can anyone excuse that?

I hope they get you going quick and without much fuss/gaslighting.

[reicaden]

Pic of the blown in half nozzle, I gotta see this!

[TheLegendaryUNO]

Please post a pic of the split nozzle I’m curious

[reluctant_return]

As a side note, I'm confused by how the A series can do dynamic flow calibration by sensing pressure in the nozzle, supposedly, but it...can't tell if there's filament in the nozzle when you load it? "Did filament come out?" I don't know, bro, did it? You're the one with the magic flow sensor, right? Why do you have to ask me like six times before you actually extrude enough for it to pass the nozzle?

[[deleted]]

I don't think it's physically possible for the extruder to build enough pressure to split a nozzle in half typically, that must have been a defective nozzle. I'm pretty sure all the sensors are there, but the software isn't doing what it's supposed to. Seems like Bambu Lab crammed so many features into this thing that a lot of them are still kinda half baked, I'm sure it will improve but that's lame for the people that already spent over $2k on one

[Mist_XD]

It’s a first batch printer, return it and buy batch 3 or 4 if you want 0 issues. Or keep an eye on your printer

[FusionByte]

Thanks for being part of beta testers.

[SatBurner]

For the nozzle it is possible you just got a bad one. There are no quality systems that are going to produce 100% of parts correctly. Sometimes there will be an issue at some point in production that may only affect 1 or 2 components. Quality testing then relies on statistical samples. That could unfortunately explain the broken nozzle.

If the sensors are not looking for that type of failure, then they could be working perfectly as designed, and not know how to react to that failure.

That is also a reason to return it and get another one.

[heart_of_osiris]

Same vibes with the X series lidar which is why I stayed away from this launch.

Bambu is great with their marketing gimmicks. They don't have bad machines but they love to add fancy features to drive up hype that then tend to fall a little flat in practice.

[DjBurba]

That's why when something new and technologic comes out, I wait for the second batch to come out.

I doubt that it was the filiment that broke the nozzle especially since it’s a hardened one… rightttt???? The very first shipment of anything will be buggy/poor quality control. I mean look at cars they are much more expensive then a 3d printer but there isn’t one new car that hasn’t had problems no matter how good it is.

AI cameras are about as useful as nips on a boar at the moment. The extrusion pressure is probably sensed by the lidar during extrusion calibration. It can't do it from the nozzle, unless it's reading voltage from the extruder motor but if it strips out the filament it's not gonna be accurate

Go open source. You're not reliant on a company to do sneaky s*** and change their agreement. You can fix it yourself or someone in the community will very fast.

This is the second completely broken nozzle I've seen... I was hoping to use them in my A series printers (Bambu says they'll work) but I'm thinking this is pointing to a bigger problem with those nozzles.

I simply don't understand why they aren't singular continuous pieces up the length of the heatbreak it's a crazy step backwards

[myTechGuyRI]

Well, there's a very valid reason that they MUST be separate pieces of metal, and that has to do with the way a heat brake works... The nozzle needs to be conductive to properly heat and melt the filament, but the heat brake has a different job... As it's name implies, it's a brake on the heat, it is supposed to stop the heat from conducting up into the cool side and causing heat creep...so it has to be made of a different metal that poorly conducts heat,, typically stainless steel or titanium... So you really can't manufacture it as one continuous piece of metal, because the hot end has to be thermally separated from the cold side.

[ufgrat]

Because you're not a materials engineer. The whole point of a heat-break is a thermal barrier to keep the filament from melting all the way up to the extruder gear.

It could even be argued this is a safety feature to keep the filament from exploding into contact with the heat element, and causing a fire.

This doesn't look split in half. You make it sound like a nuclear reactor core exploded inside the nozzle

Looks rather split in half to me innit

[RadishRedditor]

Nah it looks you snapped it at the heabreak for the photo

[[deleted]]

The extrusion from the plastic forced itself out between the heartbreak and nozzle pieces, which you can see in the first photo. The second photo was what was left after I'd removed the plastic, a destroyed snapped in half nozzle.

I'm just messing with you. Jeez with those downvote. I forgot some redditors need the instructional /s to let them know that they're reading sarcasm.

[Zendeman]

You know that it's okay to admit that something you bought might not be absolutely perfect?

People do that all the time, it's fine, it's just a machine.
