So I am in the need of making a simple IP camera adapter. I modeled it up in Fusion and sent to Bambu Labs software (latest version, printer and slicer) and it is telling me 13 hours.
It is a 7" x 7" x .25" flat plate with a 2" hole in the center. WTF?
I have had this issue on other prints and if I export again from Fusion it goes down to something like 30 minutes.
BL PLA default settings (I think). Should I reset the filament defaults? If so I will figure that out. I guess that is my next step?
There are a number of factors that will influence print speed. The biggest of which is how many head movements are generated when the slicer tries to import the file.
This is sort of a pet interest of mine since I do most of my work out of CAD and if you find a solution that worked for you, please share it here.
You didn’t mention it, but I’ll assume you’re exporting the file as an STL, as most tutorials recommend. However, try exporting the file from Fusion360 into a STEP file and see if that helps.
BTW: It’s worth noting that STL is considered the least favorable file format. You’re actually better off using a STEP file, especially when dealing with complex features and geometries. Unlike STL, which represents a mesh of triangles, a STEP file consists of geometric commands that can convert into Gcode much more efficiently, depending on your model’s complexity. In some cases, when a model has too many features, simplification might not be possible, and you’ll have to rely on the slicer’s algorithm which can often be a ■■■■ shoot.
But I will be candid. I’ve had some geometries whereby I had a simple object like the one you described and the slicer just loses it’s mind trying to figure out how to place simple hole.
If you only need to add a basic hole to a flat design, consider using a cylinder primitive in Bambu Studio as a negative part and rely on the slicing software to determine the toolpath for creating the hole. This method has yielded positive results for me. However, it does sacrifice the precision of manually placing the hole that you achieve with CAD. Instead, you might need to experiment with its placement through trial and error. On a positive note, the dimensional accuracy of the hole tends to be improved using this approach.
