Ok... this is NUTS. The H2D is an absolute WEAPON on high temp materials! This is 8" ductwork made of PC-CF that's only 2mm thick. Absolutely PERFECT. This would have been WARP CITY on retail machines a few years ago and prob a total no go for parts this... big and thin.🤯show more

My H2C is similarly top tier on high temp materials - the 65C active heating and general stability/procedures cooked in for printing at that temp, make it easy mode for any material I throw at it - I tried out some 3DXTech CarbonX unblended PCCF last month, no problem at all… I used to have keep a double paned / insulated special-built v0 to print that stuff! The HT little single AMS unit does great high temp drying too, it’s a competent system.

I imagine any of the H series would behave the same. The big ASA parts I've done on it have been great too. Its too bad the nozzle tops out at 350c... im curious how it would do with PEEK or PEKK or the seriously HT stuff.

3D Printers have gotten so good that I believe it will help make the world a better place giving kids and people easy access of bringing their creativity to life

They're not the best tool for every job but they're almost always the FIRST best tool to actually get to work on discovery. Just getting started is more than half the battle and they EXCEL for that.

QIDI i-Fast from 5 years ago says Hi @qiditech

I’ve actually never used a QIDI. If it could do prints like this back then I guess I missed anybody talking about it. Didn't think we had chamber heating on consumer gear that far back due to the patent 🤷‍♂️

Dual extruder with high temp hot-ends and 60°C active chamber heating back in early 2021. You've missed out 😉

Clearly. Why do you suppose it never caught on then? Too early? Material development? Poor marketing?

I'm not sure why. I bought my first QIDI printer in March 2017. I'd built my own printers starting in 2013 and I saw the X-One on Amazon for £360 delivered. It was cheaper than just the Duet board and stepper motors I'd bought for a printer a year or so earlier and I've never built a printer since. I've always bought QIDI printers and had great support from them. However, I need a tool-changer printer and it looks like QIDI aren't going to release one any time soon 🙁 @QIDI_3dprinter

100% dude.

Are you sure that this actually would have warped on an open printer? Carbon does a lot to prevent that. I do large, thin wall stuff all the time with PETG. I know that PC is much more print to warping, but I imagine that the carbon would mitigate that a lot

At this size and wall thickness, yes, it wouldn’t look like this. I've used PCCF on open bedslingers before and even with smaller prints in a temp controlled room I'd get some bed corner lift and layer compression. Yes the carbon does help over plain PC but this thing is DEAD flat and A+ layer finish.

Clean print!

Bambu builds great machines.

The beauty of active heating

Indeed... by MY GAWD is it a power hog. ⚡️

Lol our 500 cubes run 500w rms at 70-80c, insulation go brr

Great machine…great material..but what is current cost? Last time I checked it was $100 a kilo? Obviously the thinness will mitigate this to some degree …

Not too bad compared to the exotics. About $65 a key on the street.

with 2 nozzles, you could use a much cheaper filament for support

What was the need for PCCF? What sort of temps is it gonna deal with? Was it just more stable than using ABS/ASA?

1) Impact strength / strength to mass ratio, 2) Testing ESD effects and if added carbon can help grounding / bonding characteristics with the rest of the vent system or do I need a true ESD safe filament, 3) yes slightly higher persistent air temps, 4) Aesthetic, 5) Because I wanted to

first... I knew you were printing a vase previously!! (or sort of a vase...) It looks great, but I cant fall for the likes of the BL. glad it works for you. now if I can rebuild my old old Modix, then I could print some BIG CF pieces!

I hear you, but no brand / solution is even remotely perfect in all scenarios. There's a right tool for every job and it’s constantly shifting. I think it's important to talk about all of it, good and bad, so manufacturers can improve and customers can be as informed as possible.

Does it sound cool when you hold it with 2 fingers and tap on it (like a clear bell)?

It does have a cool sound to it but not quite the sound of annealed PPS, thats what I want to try next. Need to get an annealing oven first.

Ya that’s beautiful. I love the H2D, it is my love

I've been looking to do my refillable lip balm components in aluminum instead of casting, can this printer produce small components with debossed logo and threading with a competitive price ?

Not sure that's enough information to give a meaningful response. Can it produce small components with a debossed logo... yes, but how small is small? How "competitive" does the price need to be? Competitive at what quantity? What does switching from aluminum to plastic do to public perception of quality even if it meets requirements? TLDR: I think this or many other 3D printers COULD be a temporary / low volume solution for proving the market but it's not going to be your long term fabrication plan AND I would be particularly leery of using it with food / human contact products subject to proper health oversight.

Approx 1.5" dia x 1.25" H. Like a tapered tube. 6g in PP. What is the best way to contact you ? Would be happy to provide more info...

@grok wgat printer he using?

Impressive! 😍

WOW! AMAZING!!!!!

I can't get mine to print right at all. The external filament path keeps "dropping" the CF filament. Real disappointment.

People have been printing this on other printers with regular enclosures since 2017. There isn't anything special about heated chambers either. Heated beds were the chamber heater for years.

Sure, and I'm one of them. Not saying it was impossible before just saying it took a lot more work and heartache to do and even then it still wasn't this clean first try right off the build plate.

The firmware and slicers changed from then till now, as well as the hotends, but people who had the right gear and settings didn't have to struggle. I create new profiles from scratch for every printer because that's what we had to do; otherwise, we would get trash.

I think it fully depends on the hardware we're talking about. Its not just about purely retaining heat its about having precise controls of the thermals throughout the system. Early static enclosures weren't aware of what state the machine was in so just holding heat in or constantly venting it was a balancing act on a per material basis. I had more issues with too much heat than not enough which lead to hotend clogs and premature hardware failures for components that weren't specced to operate at continuous high heat. Much has changed since then but there's still a lot of room for improvement on this front I think. H2D is one of the first systems I've gotten to use that seems to take a lot of this into consideration and respond accordingly. I hope other manufacturers pay attention and follow suit.

Love my H2D, H2C and X2Ds.

X2d does a pretty good job also!

doubt. cf makes the pc easier to print. come back with a pure pc w/o 90c chamber then lets talk

isnt pc-cf one of the easier engineering materials? like 'print it on your unenclosed i3' type stuff?

Not in my experience

3D printing age is very nice, can't wait till the more advanced ones are cheaper or have open source versions.
