I was thinking about what Bambu could come out with in the future, and my first thought of wants was better quality and speed. Do you think they could make a printer that printed with two print heads simultaneously, which would increase speed and also let you print thinner layers at the same speed? Do you think quality can still be improved on these machines to approach resin printers?
I would jump all over higher quality printers, Bambu. Take my money! 
You set your question in the H2 Series category rather than âOther-Topicsâ. People may get confused and think your question is directly related to the H2 series printers.
You may wish to edit the topic to correct this.
To your actual question, the H2D & upcoming H2C shows their interests align with fixed nozzle printers rather than IDEX or tool changers.
While this may change in the future it seems unlikely within the next year.
They released high flow nozzles without high flow profiles. I mean i was dumb enough to buy it.
I think thereâs still some smart mathematician out there who will provide the next generational leap, with slicer [and maybe firmware], no hardware.
Thereâs so many interesting techniques to use in a motion system like modern printers have.
Bringing hardware into the fold, thereâs an opportunity for additive AND subtractive tools, or additional utility tools. Imagine a prusa XL or snapmaker U1 that prints a big fat rough 0.8 nozzled draft quickly, switches to the milling tool, carves a sheer-walled dimensionally accurate profile, switches to its laser, and engraves the part number on it. Ding print is done. Itâd be messy as hell, and maybe the mill part of that is really out of the picture, but toolheads do not need to be limited to squirting plastic. They need to be positioned to a place and told to âgoâ. This is an enormous amount of flexibility
No offense, but isnât it actually quite straightforward to create your own high-flow profiles?
Probably, but it takes time and testing to do.
If i buy an OEM nozzle and OEM filament, and use it in a currently sold machine i would expect at least a basic profile for materials like pla and petg.
How would that matter?
Filament batches are never identical, and achieving consistent extrusion requires using the exact same settings that were used when the manufacturerâs profile was created. At best, those profiles serve as a starting point.
I calibrated my new batch of ASA Aero in under 20 minutes, so the process isnât particularly time-consuming.
The claim that Bambu Lab filament should always work perfectly with an OEM nozzle and printer without any calibration is unrealistic. Even within the same brand, batch-to-batch variation, storage conditions, humidity absorption, and material tolerances will affect flow characteristics. Calibration exists precisely because these factors vary in practice.
If i buy the more expensive part claiming to be up to 30% faster then the standard one i expect it to be faster out of the box. Iâm not making parts for an airplane and i donât care if the filament is perfectly calibrated.
What i did get was a nozzle that was more prone to clogging using stock settings. I went back to the regular hotends.
If you are inferring it is up to the consumer to get any benefit with these nozzles over the base ones i disagree.
Iâve never clogged any of my HF nozzles using the default settings, so I canât confirm that issue. However, if the print temperature isnât increased, youâre trying to melt a larger volume of material at the same temperature used for a standard nozzle, and basic physics suggests that this can cause problems.
Bambu Lab uses conservative safety limits for nozzle temperatures, and these limits are often too restrictive to achieve the flow increase youâre expecting. On my X1C, I use a high-flow nozzle (not from Bambu Lab) that is rated for a 60% flow increase. With ASA, the performance is close to that figure, but with other materials the actual gain depends heavily on the filament itself.
Yes I agree that multiple print heads working together is the answer for faster production of larger prints.
It would also help with smaller multi coloured prints as one print head could be printing while the next one is getting ready for the next colour (including priming).
Making colour changes almost instant.
Iâm working on a prototype multi head parallel printer which I am hoping will demonstrate the potential benefits.
I will try playing with the temps. Thank you for the tip.
When you increase the MVS and print speed on a high-flow nozzle, you push more material through the hotend per second. The heater and melt zone have fixed thermal capacity, so the filament spends less time absorbing heat. Even if the temperature setting looks correct on paper, the material may not fully melt because its residence time in the melt zone is shorter.
Raising the nozzle temperature compensates for this by delivering more thermal energy per unit of time, ensuring the filament reaches a proper melt state at higher flow rates. This behavior is normal for all high-flow nozzles.
Itâs also important to follow the filament manufacturerâs recommendations when adjusting MVS, speed, or temperature. Just because the nozzle can handle a higher flow rate doesnât mean the filament can. TPU, carbon-fiber-reinforced materials, and many other specialty filaments can degrade, print poorly, or simply clog the nozzle if pushed beyond their intended limits.
What I want to see next is the automatic removal of prints from the build plate after printing is finished.
This will allow users to do multiple prints remotely.
Since the plate doesnât have to be pulled out (by hand), it can also help to keep the plate stay free of finger oils longer.
