Disappointed in your comments about Bambu

[Lee David]

Good day,

I have listen to your podcast for a few years and I will keep listening.  You guys have a lot of experience and I have learned from your podcast.   I am in machine tool industry, primarily milling and have customers running state of the art 3d printing for Aerospace and Defense.  

I was disappointed in your comments about Bambu.

What you all have said over and over, Core XY, 3 point leveling, direct drive, etc... and most importantly, Quality, is what to look for in a printer.  This is exactly what Bambu built.  

I understand your dislike for closed systems.  You do not like all the sensors, Bambu P1P for $699 is everything you said is best in a printer except closed system.  Bambu had to close the loop so customers were getting good prints out of the box and I can see and understand why they did.

3d party parts are important, I am already finding some 3rd party parts on Aliexpress, and as sales increase 3rd party items will as well.

What really urged me to write in was your comment on the last podcast comparing a MK4 to a Bambu...  I did not understand why you would compare a bed slinger with a CoreXY with all the features you recommend.  

I have a small group of printers I use for prototyping and custom items.  I own Creality, Anycubic, Flashforge, Sovol and Bambu, by far Bambu is further advanced with greater quality than anything else I have run.  I have tweaked and upgraded my Creality Ender 6 core XY to the point it is no longer Creality and still cannot achieve the through put and quality I can with Bambu P1P or X1C.

For me, the quality and speed of Bambu has been second only to Voron (I may build someday) but with support.  The Bambu team have built detailed instructions on just about every scenario you can think of in their Wiki section.  For users that are not mechanically inclined Bambu has a real support system that has worked for me every time.  Is Bambu perfect, no, do they seem to be addressing customer issues, yes, or at least for me they have. 

I think you are missing out on a great printer and company.

Thanks for the comments. We really cannot say anything bad about the Bambu beyond that it is a closed system. I read the posts in the Bambu forums and I don't see universal praise. Should we just buy one so we can speak on it? Not feeling positive about doing that right now. Why? Listen to the show tomorrow... particularly the first segment. I do not expect to buy another single extruder system again. I no longer get underside marring from perpendicular break-away supports. I can finally print at home the way I used to with the SSYS Fortus at the factory on the hill... Ten years later. Finally.

Yes! For me, the wasted filament from the poop chute (and wasted time in color swapping) is naturally the biggest downside to this printer. However, that said, I love this machine. Soooo fast. Soooo accurate, hot swapping full nozzle assemblies is about 2 screws and 2 minutes. Full color printing without having to load up has spoiled me (16 bays). I do love that the prices on all their parts are really low cost relatively speaking.

My Bamboo almost never sleeps. Eventually I will run out of things to print for friends and family, but this thing is a workhorse.

If ya’ll purchased one, I suspect your segment and sentiments would only change slightly. I predict you would be impressed with the build, speed and performance. Closed system would still be a bummer and you for sure would rail on the amount of poop (however may give some insights on your method for tweaking the poop multiplier. Tower would also be another bummer for you.

Perhaps you could share some insights on how to optimize printing on the Bamboo and reduce waste—it would be fascinating to learn from your experience.

Let us know if we all need to bump up our Patreon subscriptions to help fund an X1 purchase!

Love the show! Carry on!

Ross

I just finished a print on the Bambu X1 using orange PLA+ and black PETG.  I set the supports to 0mm Z from the print and had the supports print solid tops.  Worked great.  No underside marring.  Timelapse video of the print is here: https://youtu.be/bQ_fDHtOHUU   Bambu slicer lets you minimize the filament changes by only printing the interface layers in a different filament.  So most of the support is printed in PLA, only the part of the support that contacts the final print is in PETG.  This was 19 filament changes over 128 layers.  I attached the Bambu 3mf if you want to see all the print settings.

By the way, this  worked way better than using the PLA Support filament Bambu ships with the X1 Carbon combination.  I think I will throw that filament away.

So go buy a Bambu X1 and play with it!  It will do exactly what you want it to do.

Well… it won’t print at 300x300mm print. It’s build area is too small.

I find myself constantly having to work around the purge lines, only to forget the P1P doesn't need them only my X1. Print area is small but just a compromise for now. I had to redesign a few projects to gain a few mm here and there.

I did redo most of my print profiles on other brand machines to get the same speed, I had not tried in a number of years to run quickly. Aside from 5C temperature difference they are all hitting the same print times.

I cut nearly 24-hrs off some prints across my fleet. Print quality is fine, some a bit worse but nothing a customer will be likely to spot. Had to work on retractions to avoid any issues or webs.

Is Bambu contributing their improvements to the slicer (which is required due to open source?)

They are not required to "contribute" them under the license (GNU Affero
General Public License v3.0). Bambu Labs is required to make available
the complete source code of their modified version. (Which they appear
to be doing, https://github.com/bambulab/BambuStudio.) Whether or not
the copyright holders want to then use those changes -- pull them back
into their original work -- is up to the copyright holders. Bambu Labs
is under no obligation to "contribute" back their changes.
