Hello
I’m printing a ball with some intricate details on the edge. Bambu Cabon with a 0.2 nozzle, Sunlu PLA matte 1.75mm with the print speed to silent. Good adhesion to the plate with glue, calibrating well.
But all my designs have this spaghetti on the edges of the pattern that is printing on the object.
Sending through a couple of examples. I’m printing a ball that has a pattern onto of it.
Assuming the bottom of the ball, as we see it, is what is the one on the bed plate it looks like it is in need of supports. At least that’s what it looks like to me. I’m sure the folks with a lot more experience will chime in shortly.
It is a support / overhang issue. You are printing in mid air basically…
As the slicer will print the outer walls first, your big overhangs are mostly in the air.
You can change this order to inside first, but, I don’t it will solve it, you likely needs supports.
When you preview the model in the slicer, can the view to line type and look at the different line types displayed, you will likely find a lot of overhangs.
You can also use the sliders to review where the filament is printing. Chances are, it is being printed in mid air.
Supports are your friend here as already noted by @N1MIE.
Ask yourself, "What is the layer being deposited on? In the pictures, the trouble is occurring in areas where the filament is being extruded over nothing at all. We can let the plastic overhang the previous layer a little bit, but if the majority of the line width is unsupported, gravity will make it fall.
Thanks. So how do I edit it so that it has more support? Is this an error in the STL file? Or my printer settings?
In BS use the settings panels on the left and look for the support related tab.
Press the checkbox next to enable support.
You can now experiment with the type of support need.
I would recommend turning on the “on build plate only” option.
Try tree and normal supports to see which works best for your models.
Is 3m38 seconds a lot of overhang for a 2day print? Is that what I’m looking out for.
I’m going to change the change the overhang settings as The Oracle suggested!
This also shows why radiused edges can cause trouble depending on orientation. I’ve quit using them on horizontal edges because the changing amount of overlap becomes extreme. A constant layer offset chamfer is much less troublesome — if a model allows it. Some you’re just stuck with support.
