I have a model that needed to be shortened in a few parts, so I cut the model and moved the top portion into the object below it to shorten. Once that was done, I assembled everything, created a union between the two via mesh boolean, and printed.
Upon printing, even though the two objects were “merged”, a small line appears where the object was cut. Does anyone know how to remedy this?
Before union:
After union
Print:
If you look in the slicer for the internals, do you see 2 objects next to each other with a thicker wall at this location or just one object?
There is no easy answer to this. The slicer does not offer a tool that would allow you to align two objects. You really need CAD to do this type of work in order to get two geometries to mesh together around a mating connector.
A “possible” workaround is to use the right-click center tool.
The trick here is to create an alignment set of primitives and lock them into an assembly. This will give you a rectangular framework to use the centering tool.
It’s complicated and if you really are up to it. I can post a tutorial here but it will involve several steps to guarantee alignment.
Here is before cut:
After cut & recenter:
After assembling:
After union:
I just cant figure out why it throws it off
I added images of before & after a cut on this object below if you’d like to see.
I centered both objects to realign them, but after I overlap and create a union, it throws it off.
Just a heads up. The latest version of Bambu Studio does allow this in the assembly environment.
That being said, I haven’t used it yet and don’t know if it works well.
Try slightly overlapping the two parts when you join them.
That would be something to try but it seems the slicer treats the part as if it had a small angle along the length like a taper with an unsignificant angle and so getting the parrallel off. Do you use arachne and/or 0.2 nozzle? If the line width was large enough, it may have no way of rendering that taper, switch arachne off if set and check result in slicer.
Try not using your mouse. Try dialing in the numbers of alignment directly into the positing tool. This will give you much more precision albeit through trial and error.
That’s what I’ve done, but it’s still occuring 
I totally think this worked!! 
Going to print a sample now to confirm!
