I knew that as one of the early adopters, there will be glitches, probably software issues, errors etc. I did not expect the print quality to be this bad comparing to my previous P1S which was close to flawless, after 1000+ hours.
Z banding is a topic on its own, and probably my biggest concern, but it’s not just that. Layer visibility on conical objects is so annoying.
I’ve tried all calibrations, automatic and the usual combo I am used to do from Orca slicer - Flow, Pressure Advance (Flow Dynamics), of course temperature.
I’ve read the post about cooling and adjusted printer/filament profile accordingly.
Today I printed one object on my old P1S that I sold and when I look at it, at the difference in print quality using exactly the same PLA, layer height etc, it’s making me seriously consider selling H2D with all the financial losses and in fact considering a different brand at all, given this experience.
I did print quite a few hundred hours with Prusa MK4 and XL, they were not bad but by far as not as awesome as the P1S.
I’m really thinking what else should I try on the H2D to get the print quality up. Latest beta firmware, I even bought the $100 precise calibration plate. no help.
Was the same for me. I returned the H2D and kept the P1S. I think it still needs time to reach its full potential. I will have a look again in about 5 months.
Was it difficult to return? Must have been a real pain to pack up. I just ordered the h2d and already having delivery problems right after it left the warehouse tracking showed a delivery failure. Live chat said the label was unreadable and a new one was put on but I need to contact support via a general ticket. Which i did put in. I’m in Massachusetts. The printer is still in California 3000 miles away.
If I get it and it doesn’t print as well as my P1S with 2000h I’m going to return it. $2500 after tax is nothing to play around with.
Certainly there are some flaws, which was to be expected. But there is no technical reason, that the H2D is generally worse in print quality.
I also have recognized some parts to be worse than on my X1C. But extrusion lines are actually better on the H2D, less artefacts etc. You only notice that with direct comparison.
I will certainly not go back to my X1C. Compared to the H2D, the X1C feels like a toy. I would expect that the print quality of the H2D will improve with software and will be above the previous models. If anybody says the opposite, please provide a detailed technical explanation why the H2D should be worse!
I can’t say that I have noticed any big differences in print quality between my X1C and the H2D other than less pronounced VFA’s on the H2D.
It is however interesting to see people in the community who begged for a huge printer finally come to terms that a larger printer isn’t always better in all areas. There are compromises in both speed and quality that need to be made when scaling up in size. I personally feel that the H2D does a great job mitigating these short falls but I don’t think it will ever be leaps ahead of the current X/P series printers in terms of print quality and speed. I am however loving the heated chamber. This seems to make a big difference in print success.
Head weight + high acceleration = excessive smoothing needed for input shaper. This should only affect small details like lettering though(like the lettering on the rear of a benchy). This is the only thing I can think of that would make h2d quality lower vs x1c.
I received my printer yesterday, ran all the calibrations and there is nothing wrong with it.
Been printing PLA, PETG-HF and ASA-CF and they all come out perfectly.
No Z-banding, adhesion problems and it’s super fast.
i can imagine that when you have a bad one (either due to poor shipping or poor assembly at the factory), I believe it is still a great printer.
If there are serious issues, a support ticket is the least you should create to give Bambulabs the chance to resolve the issue and see if you can get it resolved.
I don’t really underwhy people in general are obsessed with printing speed. All my prints are set to 150mm , lower for inner and outer walls, and no more than 2000 acceleration and 300 for travel time. Sure it takes longer, but if I get a print now or 3 hours later, so what.
Also, the slower you can print, the better it is for printer wear and tear anyway. Massive acceleration is hard on the health and longevity of the core xy system
Post a picture of the bad print quality. I’m curious if it is a problem or expectations. I understand suggesting your expectations are too high is a little rude, sorry. Not the intention. But people have different expectations when handing over $2,000+, so, I’d like to know where your expectations lie.
For the downsides, all I noticed is significantly heavier shrinkage layer line (benchy hull line) due to not that ideally tuned profile. A little bit more work to fix but not unfixable. Oh and probably the loss of lidar, which is pretty reliable now on the X1C for both flow dynamics and flow rate calibrations.
But think of colour changes. With H2D you get much faster color changes if you’re just using 2 colors and that is great for reducing layer inconsistency. I get wonderful quality multi color prints.
Also you get way less VFA (though it was never too much of an issue on my X1C as well), never clogging extruder, active chamber heater that reaches 65C that absolutely conquers ASA… As a printer, it’s literally all I ever wanted (except for the loss of lidar again
Seriously?
I’ve been printing for close to 10 years with home built printers and purchased printers.
This printer is as good as it gets for a hobby use printer.
Show us a photo of what you are griping about or I don’t believe you!
Would still be interesting study to see any similarities. I’m sure most of us have a similar spool of filament or several if you like to hoard filament.
no, was not difficult. It takes a moment to re-package, but the wiki offers a good guide for doing that. They also returned the money quickly but there was some back and forth because bambu did not refund the whole amount because of some calculation error on their end. Took three messages with screenshots etc. to explain their mistake until i finally got the whole amount.
What’s your location? I’ve got 1500 smackeroos with your name on them. I’ll save you the trouble of making sure you still have all the parts and accessories and packaging it all back up
