Broke my Bambu Labs H2D to Show You What's inside

Damn ! It's both so cool and intimidating at the same time. Overall, that's quite an impressively engineered thing.
How did the re-assembly go ? Was it as much a PITA as it was during disassembly ?

Feels like the move from mechanical cars to the ICE engines of today; the addition of many sensor single points of failure that will drive many users crazy when the unit randomly fails.

The bed heater is so disappointing for such an expensive printer. Really would have liked to see a kapton heater to get much more even heat distribution.

Muchas gracias por el video!!. Valoré muchísimo ver toda la electrónica. Sorprende como han logrado hacer una excelente impresora con componentes que vemos a diario en otras impresoras… no todas, pero varias piezas las reconocí. Larga vida a Bambulab💪🏻🙌🏻!!

Hmm I thought that you could upgrade the 3d print only version. But your statements do suggest otherwise... a bit of a disappointment... T🤯he printer head is a sort of engineering art work. Amazing.

timelapse for putting it back together would be interesting to see all
still works

I think it's cool that the complexity of the tool head is impressive to you because that is absolutely a statement an engineer would make LOL... But to me I honestly really feel that tool head is extremely over complex to the point of being a bit silly tbh. That amount of complexity teaches us something about the state of the company as it is today. They absolutely are convinced of their superiority to other brands in the space and showing a disregard to customers who may want to repair or keep their printer for a long time. If this was a company who really cared about the long loyal dedication that a company should want to build with their customers more time would have been put into that tool head as well as the way it's constructed thinking about how much pain it might cause someone in the future working on the printer. Complexity would have been reduced with all the same actions and benefits achieved.. That's all well and good though that's why an open and free market like what we have here in the US is the best in the word as it fosters innovation. Something those in China don't have the luxury of experiencing.

can the door be made to open the other way?

Thanks for sharing. Id never think bambu would use such cheap cables in this expensive of a machine, its easier to replace these steppers with no driver boards in them.

Can you assemble it?

I would never know how to put that back together again. I have a feeling that if I tried I'd wind up with a machine that extrudes laser beams.

Thanks for the video!
I changed my mind about upgrading my x1c to n2d, it will be so difficult to service the printer that I am not ready for it.

This was amazong. Watched the wohle video. Did you manage to reassemble it ? I could not imagine how. Well done.

that 'What the FUCK!" when you broke the screwdriver had me rolling

There are lots of little surface level things that I noticed when setting mine up that made me give a nod, like the aft sir screw which is actually sealed inside a rubber pitot keeping it from falling into the printer when you remove it. The instructions even say to be very careful it doesn't fall in, and I feel like they saw that as a pain point in testing and added the pitot.

Hi, what's the name of your ratcheting T-Wrench ? Lock pretty solid
Thanks

First of all ,a big thank you for getting through all that hard trouble of dismantling this printer ,
to show us how it is assembled .
I have dismantled and assembled some printers in my time and is nowhere a newbie
when talking about dismantling or assembling stuff generally ,but the way Bambu
have constructed this is insane .
I am glad that it is not me that have to assemble this printer again ,the amount
of time/hours to get it back together again must be huge .
This reminds me of the time i went for broken paper printers to use for parts
and one day came home with a paper laser printer ,the way that one was
constructed was on another level , no space left for anything ,not like
ordinary ink jet printers that have huge empty spaces :-)

I am impressed by the construction and engineering of this machine. Huge amount of work and testing there. Still not buying one because it is Bambulab... But I have to admit the concurrence has to improve to keep the pace!

Hd2 still isn't worth it or innovative. Just smash together tech that already exists.

how much time did it take to assemble it back again? :)

a production / quality tip: please use manual focus prior to putting your hands in frame. the camera's auto focus constantly changes focus to your hands and ruins the shot many, many times. very jarring to the viewers and frustrating when what you want to look at is constantly going out of focus.

At this point, as a owner of X1C I must say: good luck debugging and repairing H2D when stops working properly and think it would work as new after the repair job.

That thing is complex af and you need either a neurosurgeon degree or another flavor of autism to be able to make it work as a machine out of production line. 😳

Thanks for sharing the findings! You make the internet a better place! 🫡

What a plasticy, proprietary mess

As someone who craves to see the insides of electronics but doesn't have thousands of dollars lying around, thank you for this. Sat down with a Popey's burger and watched the entire thing like watching a TV show

I wonder if it takes more time to assemble the head than the entire printer on the assembly line. I believe in the new quarter bambu will release firmware update that will make all this crazy engineering worth it. It will all be justified. Right now they fixing high volume manufacturing issues. That might actually be 2 different team.

Very nice video to have, but I'm disappointed you didn"t show anything of the heater and filtration assemblies. We didn't see how the second toolhead fan cools the cold end eithers.
Also, the toolhead has 3 motors : one for the extruder, one to move the hotend up and down, but you didn't specify what the third one (second to appear in the vid) does.

This thing is a nightmare to maintain

Overengineered maintenance nightmare... X1\P1 were quite awful, and those ones are even worse.

Can the door hinges be moved from the left side to the right side?

I now see why these things cost so much.

Waiting for the video of you putting everything back together and testing. 😁

too expensive

amazing machine ... but a bad printer for me
im not a fan of the direction bambu is going by chasing the multi head extrusion trends instead of making the best neclosed temp controlling printer around
i want to quickly and acuratly prototype parts for use, i dont want to make colorful plastic waste ;/ also it just seems way too conmlicated now, all this pointless tech for laser addod and multi heads just add to what can break

It's too complex.. how can user even fix it when it malfunction? the printing quality is nice, but maintenance? hell..

An over engineering products. As I did engineering more than 30yrs, engineering prototypes need only one type of material per parts for functional review only. For marketing purpose uses which need color prototypes and doing some overmold tpu soft materials on handle, two or more materials in a prototype may need, but for colors,  painting can achieve the task. At the moment, I won't buy such expensive machine for home use. Moreover, I already have an low price old 3d machine which is twin nozzles type, I can print two materials and is enough

Würdest du den Drucker auch so lieblos zerlegen, wenn du ihn selber mit deinem Geld gekauft hättest?

I despise hex screws. Tend to replace those with torx whenever I need to take them off in any device.

Very sensitive components and many moving parts, I would prefer not to mess with this machine.

(building technician) wtf i just put that together...

It must take factory workers like a solid 3 hours just to assemble that toolhead, damn. That is impressively engineered but so complex, so many cables and connectors. It is almost unbelievable.

Great work and a lot of effort! Thank you for that bro!

Damn its like working on a modern vehical, there's gotta be 1000 sensors and mechanism inside that thing. Starting to make me thing twice about buying one. Looks like a nightmare to work on it anything fails.

Not surprised to see the over torqued screw. They must not use programmable torque/rotation DC tools.

wow that was cool, thankyou.

WOW... thanks for the tear-down. As a QA guy and system's engineer, root cause failures and serviceability are paramount. I fear the design is over complex with connectivity issues and component failures just waiting to rear their ugly heads as all things fail given enough time. It would be interesting if Bambu Labs will take the time to simplify this design.
I wonder if Bambu labs will be issuing an extended warranty program for those folks who want to use this machine in printer farms.

Can't believe how intricate and complex everything is. It makes the asking price an absolute BARGAIN.

Did you take apart the chamber air recirculation assembly? Curious about filtering

This is insane! This is really now a ROCKET SCIENCE! Damn, just look at this toolhead... old Ender 3 looks like a Stone Age tool comparing to this monster.
All components have to be feaking reliable, or it will be a pain in the ass to teardown and repair it. Anyway, BambuLab took it to another level AGAIN. I don't see any other 3d printer company to get even near that level soon.

Bro Hats off to you man.This is the most helpful video I have ever watched,from a long time I am designing my own corexy pen plotter and you help me a lot by reverse engineering
