Is there any know procedure to increase the dimensional accuracy of the Bambulab printers? What possibilities do you have with Bambulab Studio?
The dimensional accuracy is not bad. But I found out that there is a deviation between X and Y axis on my device. Further, all holes tend to be too small (approximately 0.3mm for D<10mm). The latter can be corrected in CAD, sure. But it would be much more conveniant to compensate that with the printer SW.
Since there are various errors I was wandering, if there is a known procedure to identify the error first, so that you can counteract.
I only entered the X1C word two weeks ago, yet printing 24h a day.
I mostly use it for functional and using engineering-grade materials, for which tolerances and dimensional accuracy are critical. While waiting for the older delivery, I took some time planning calibration procedures, e. Nevertheless, I still use Bambu Studio and default profiles since they work flawlessly.
The only failures I experience are related to the filament moisture; it is pretty noticeable that the filament requirements are high and cannot be ignored. My issue was with one spool of ABS, for which the prints were slightly smaller than sliced. I solved this by drying the filament.
If I were getting those values, I would mostly look for mechanical or filament issues.
Is it a constant issue or specific to a filament material or brand?
What filament material and brand are you using? Are you using the slicer default settings?
Sorry for so many questions, but it is needed to understand better and help.
Does anybody else have issues trying to print multiple parts at once? (Same part duplicated). I’ve attempted well over 20 times and can’t seem to get a finished successful print by any stretch of the imagination even using the same exact print settings as used for printing just a single part. Doesn’t seem to make a difference if I use glue or not. X1 Carbon doesn’t seem to deliver on multiple part printing. Slowing down the first layer seems like an obvious option, but that has not even helped. Spaghetti central over here.
Ive had success printing multiple parts at once, but have noticed that first layer adhesion issues can occur near the outside edges of the build surface. I increased bed temp for first layer to solve that issue. Otherwise no other problems.
I also had success with multiple parts with any sequence.
If the multiple parts occupy a large area of the printer bed or/and entail complex geometries, I usually have a couple of failed start-ups before it works… one of the main issues is the lack of options to exclude the failed parts. I already got a clog because of this.
In case of failure, I recheck the bed sheet cleanliness or homogeneous spread glue (on which I fail), as this tends to be a critical factor.
If that is not a problem, I move to the slicer and start the tedious process of improving the printability of the multiple parts, e.g. changing parts’ location, increasing or changing infill pattern, or even reducing layer height in critical regions. In most of the cases, it is my error of not paying attention to the print process.
Is it with a specific print file or filament, or does it happen to all?
I increase bed temp to 50 degrees celcius for PLA. I don‘t use any gluestick. I have issues with bed warping but never had problems with printing multiple parts at once.
I’ll try raising the bed temp to 60c and see if that works. One thing that has helped in general is slowing the first layer print down to 15mm/s2.
I do have the same issue though with just certain areas failing repeatedly. I’m coming from a raise 3D printer that was marvelous at printing multiple parts at once right out of the gate. The more I tweak the settings to the raise default slice settings, the better Bambu is getting. I’ll say the quality is definitely great on the bambu if everything works out on a print.
And why did you downgrade from a 5k raise to a 1.2k bambulab?
I have never printed as slow as 15 mm/s. I use default values. The only value I had to change was bed temp, but this might be because I just don‘t use any glue.
My raise printers are a little long in the tooth. They are Gen 1. Still having issues with Bambu, but printing one at a time at 15mm/s2 at least keeps them sticking to the bed.
On my old creality printer there was a setting in cura where I could choose middle outer or inner for walls. Here it helped with accuracy if I chose inner. Default was middle
