I am trying to print this phone mount for my bike. When the part is printed at an angle the corners are not 90deg anymore. the rectangular becomes a parallelogram. The other parts are at an angle as well and have the same issue. As seen in the pictures attached.
printed in petg hf with he default settings of bambu
Does anyone know how to solve this problem?
I already re tightened the belts x,y and z
Printed with more supports
Top opened of my p2s to keep the camber temperature at max 38deg C
Is there a reason why you’re printing it at such orientation - which, of course, can make the problem even worse - instead of printing it the way the designer intended?
In the orientation intended by the designer, the problem shouldn’t actually occur at all, but your orientation is completely tilted, why? Why don’t you start the actual print not from the print plate?
Because an FDM printer can only produce straight walls when they’re positioned upright. If you tilt the wall at an angle, the issue becomes much more pronounced.
Since a slicer works layer by layer, it simply can’t interpret slanted walls perfectly. That always leads to some degree of trouble - sometimes more, sometimes less. On top of that, you have the physical behavior of the filament, vibrations, and other factors. The designer definitely had a good reason for choosing that orientation.
I really don’t think so, because the designer must’ve had a good reason for putting the layer lines right along the line of force. It is positioned exactly so that the most critical point in the alignment - as intended by the designer - is maximally reinforced.
Understandable, but for now the question remains whether this is a problem with your printer or simply some odd orientations and settings. What does a regular cube look like when you print it using the default settings?
Do us a favor, save your 3mf and post it here please so we can take a look at it.
I have a couple theories I’d like to dig into.
Once you do that, you can try starting a new project in Studio, right click on the plate, add primitive, select cube, and do the same process to rotate it 45 degrees and add supports.
Then right click the cube, clone it, and then rotate the clone 90 degrees on the Z axis - we want to see if this is happening in both directions.
Yes, I posted that video in this forum. You left a comment under it and I suggested that you start a new thread about your problem, which is what you have done now.
However, the video isn’t about printing everything at a 45° angle - quite the opposite.
I think you’re mixing a lot of things up right now. Please try following CarbonForge’s recommendation.
Elevating the part off the plate and adding even more support would seem to make the problem worse, not better.
If supports do not break away cleanly, fix the supports.
Calibrate the filament, change Top Z distance, change the interface, whatever is needed. ____________________________________________________________
Printing on an angle doesn’t magically make the print “stronger”; it makes it weaker in one direction and stronger in another.
This original orientation is the strongest for the portion that clamps the handlebar; forces on that part are perpendicular to the long, continuous layer lines.
Rotating the part 45° creates shorter layer lines and weakens the bar clamp. It will break with less force, and split at an angle between layers. Layer adhesion in the phone clamp area is already reinforced by the screws clamping the phone. ____________________________________________________________
If you still want to rotate the part, leave one corner on the plate. The part will print with a brim and support only in the bolt holes, and I suspect that if slightly ragged holes were acceptable, it could be done with no support at all.
The out-of-square issue is very strange. I would have expected that much skew to also alter the height of the channels for the side clamps, but apparently they still fit.
Seeing the .3mf with your settings that produced the error would be very helpful, as would the results of @CarbonForge’s suggestion to print a tilted cube.
