for the next printer i have a idea…
realistically - we definitely need a 6 spool ams and a big 400x400x400 A1 with dual nozzle like the h2d or maybe even votek 
!!
That size of printer might have a hard time fitting through most standard doorways?
A printer with a build volume of 400x400x40p could require external dimensions of 725x640x691mm,.
These are within acceptable constraints for entry into most properties when still packaged.
You refer to
I believe you are referring to an IDEX printer, standing for Independent Dual EXtruders.
An interesting mechanical problem, but achievable.
Unlikely to need that amount of extra space.
These two things are not the same. The P, X and H2 series are Core XY, the A series is not.
Yeah, the A series printers are not enclosed, just stick with the core XY references.
Ideally the straight duplicate mode as well as the mirror, sometimes you need two feet, other times, two left feet.
This part is confusing your overall wish. A multiple toothed printer works by having connection to one material throughout the entire print and the printer grabbing it already primed ready to go at any time.
If you add an AMS, you are removing all the benefits of a tool changer.
But, some good news. Your 400x400 build plate and extra size on the left and right probably allows for 8+ tool heads rather than the 6 you suggested.
The snapmaker U1 has 4 on a build size of 220x220, around 55mm each.
Maybe 8 primary and one extra for support material for those who like the smoothest and most complicated printers. You could use all 9 though…
Definitely not, this is the wrong direction for tool hangers as it only changes the nozzle and we are right back to the delays caused by the AMS request above.
Exactly. In Australia most apartments’ hallways can barely pass through an H2D/C package. I don’t know much about other countries but I can imagine the difficulties.
The minimum hallway width in residential buildings in Australia is generally recommended to be at least 1000mm, with 1200mm being ideal for better movement and accessibility.
Provided it was built during that code requirement, you would be more than fine.
You may need to push from one end rather than grabbing from the sides of course. Just balance it on a couple of skateboards and you are golden.
Same with Canada, H2 series barely fits in the door.
The RatRig IDEX 500mm ships disassembled due to its size. You can buy it fully assembled through their new Disrupt Engineering division. It has to be shipped via a freight company (and not a traditional shipping company) on a pallet, just to give you an idea of whats involved with something that size. Just the shipping can be in the $2000+ range.
This is only for hallway, but the door takes some space. For example, my door has a clearance of 80cm. And it’s not some “really narrow door”, it’s just very common apartment doors that’s probably used in 90% apartments here (if, you’re not rich enough to afford a house).
The only way I can find it to enlarge the printing area without stucking in the user’s door, is to get rid of the side aux fan, by taking over where the H2D laser air pump currently is or other empty chambers in the back. But that only extends the X axis anyway.
Are you telling me you would not consider throwing it up a couple of stories in through a window from outside?
I had far more faith in you!
So, you do not have American visitors then, also, my British mother is definitely not going to visit you.
Sounds like you want a 400mm idex ratrig with dual bondtech extruders and box turtles going to 2 of the nozzles. Give it time.
I just put a Sovol SV08 Max (500x500x500) together and I can’t picture moving it now that it’s assembled. Pretty sure if I ever sell this place I’ll throw it in… does one giant printer count as “furnished”?
Is Bambu selling printers or doorways? Does Ford or Mazda or anyone care if you have a parking spot for your spankin new car? Nah F. that, heres the product, make your room if you want it. What are they even gonna need to babysit people on their interior design now?
You proposed an oversized H3Indx and you closed your proposal with saying a bigger A1 , I dont really thing youve got your vision straight, but you are on a good road.
Yes it does, as it can print all the rest of the furniture as needed.
When my ex-girlfriend needed a pizza oven taken out of the building, we decided that taking it apart and putting it back together was for amateurs, so we just drove a forklift straight through the wall. It should be mentioned that this was an industrial pizza oven and absolutely gigantic. Turns out that when you’re determined enough, even the building becomes a suggestion rather than a rule.
I really like my H2S, its a great printer.
But H2D? No. Nozzle swap time still way too high. Like 10 seconds or so will still slow the print down way too much.
Look at V-Core 4 IDEX, nozzle swap time is like 0.5 seconds. It’s really simple, nozzle rests on metal plate to make sure no oozing happens and pressure is kept, thus no purging, cleaning and primetower needed:
Or that one, should allow similar fast nozzle swaps. But ofcourse in small and lightweight and with only three nozzles and some mechanism that closes the nozzles that are not in use.
First one is cool and can be mucb faster than that video even shows but the 2nd one must weigh a ton. The 2nd one would be great if it were stationary, and the bed was a core xy slinger, but the overall machjne would need to be huge. Something like roetz 4.0 on youtube’s sub one minute benchy machine. Where the toolhead only moves in the z axis
Yeah, 2nd one is just to show the principle, it would need to be a lot lighter, stiffer and more compact. But I have no doubt the Bambu engineering department can do this. That would allow nozzle swap time to be like 0.1s or something like that.
Hey, dont think im trying to argue. I love these conversations and they are rarer and rarer these days. The 2nd one would still requite a cut and therefore require a purge/prime, to get the cut point into the melt zone for retractions. All that to say that the vortek probably does it close to as fast as the 2nd video, if youre only counting the time of the actual nozzle change and not all the supporting movements, purges etc.
With the 2nd video, if the toolhead was stationary, you could justify having the added weight of multiple ptfe tubes and a coupler on the top of it. That would drastically cut down swap times. That requires a different type, size, weight and price point. And also requires the print to be the moving part of the operation. Tall skinny prints will suffer
End game of fdm is (if you refuse to go full toolchanger or nozzle changer) Is an idex like video one, with a material switcher like an ams going to each head. Then allow the parked head to purge filameng into a side mounted bucket, while the other prints. It would require a slightly wider printer than the vcore setup. Would put a cutting arm on the left of the left toolhead and right of the right toolhead. Cutter actuation arm at the very end of the x axis. Tool head 0 finishes printing, taps cutter actuation arm as the next toolhead 1 starts printing. AMS does its thing. Jn the meantime toolhead 0 wipes across the ribbed nozzle blocker section just in front of cutter actuation arm, then moves slightly inward of it to purge into a lower bucket and also cools/rams during this purge to just above softening temp, moves back the ribbed ooze blocker and continues to slowly wipe while cooling to just below softening temp. Rinse and repeat. Then people could choose between print times and print waste as the two tradeoffs between a 2 nozzle machine and the waste savings of the vortek.
Or solve it all by mixing the indx idea and the ams. Save time, waste and still have access to a ton of colors. Think of four toolheads or even just nozzles with ptfe attached. and two of them have ams access. Could fit it in the x or p chassis.
General 3d printing end game is an inkjet resin printer like the stratasys or eufymake that does normal prknt volumes for a good price. Super fast, zero waste etc
What would be fun is that bambu themselves does some polls and find out what we want them to focus on next. I doubt they will want to signal how they want todo things but it would be great to have more input on the direction. For example i am slowly accepting the lower speeds on things. Starting a print at times takes so long but its also checking way more than other printers and that results in less issues and better results fine. Same with i think the prime tower and waste it seems bambu in interviews it seems they want to focus on that next and having input on how the compromis are made would be nice to keep them on track. Its clear in next year we will see a speed-race where many brands will try to proof they are the fastest in 4 or 5 colors and that will be the selling point. If bambu wants to be different and focus less on speed fine but give us something in return again (like hotend management or even better multi material ways like the tpu issues).
There is a surprisingly large number of 3D printing technologies - from laser melting/sintering to HP’s processes. However, for home use, FDM printing is the only viable option due to occupational and environmental safety considerations. Everything else is far too complex and far too expensive for private use, and would never receive approval for home applications in the regulation-heavy EU.
I believe the race has long been decided in favour of FDM printing. And I hope we will continue to see wonderful innovations, both from printer manufacturers and filament producers.
