Is there any way to quickly print a part of my model?
I have a challenging over-hang section and want to dial in the print settings I need for this first.
I know I can use negative parts to exclude parts but it is not quick to exclude all parts except the part I want, Ideally I would like to just have a rectangle and only the things in the rectangle get printed TIA
The quickest way is to trim the model in your CAD software. I don’t know of a “quick way” in Bambu Studio but there are a couple options. Lower the part into the bed to the point you want the print to start at. Use the “Cut” feature to slice up the model and remove the sections you don’t want to print. The other option as you mentioned is to add negative squares to the model.
As Jon mentioned, you can just lower the model below the build plate, use a single exlusion block for xy exlusion and pause/abort the print (slice, then right click on layer where you want to pause, insert pause, slice again) above the volume to be tested. Should be 1-2 minutes in the slicer.
Use the Cut tool in Bambu Studio. It may take some minutes to figure out the interface, but you got it once, you got it. It’s my go-to tool during prototyping.
I know this is an old thread, but I would love to be able to use modifiers as a “print this area only” feature as it would be much faster to use during prototyping than using the cut tool.
The cut tool is great, but if you have several joints in your model that you would like to test it’s a bit more tedious than placing modifiers.
Does anyone know if this feature is available or if there is a way to use modifiers in this way? Cheers,
Add negative part is a feature that removes the portion that intersects with the added shape from the model when slicing. I haved used it only a couple of times so far when needed to skip sprinting some middle portion of the model.
For printing the portion in the center of the model while skip printing the outside portion, maybe one can try the Add negative part feature and choose the Torus shape. One would have to scale up the torus to just the right size to skip slicing for the outside portion while printing the center portion. But it’s not going to be a one or two-click operation. So using the cut tool may still be easier.
Another way is to load a custom shape as the negative part. But then one would have to design that shape first in CAD.
This is great advice! Thank you so much.
This is great, silly to complain about the cut tool, but it is a bit clunky when prototyping and I just want a small part to test. Negative shapes, might even make a custom C bracket, but cubes are probably fast enough. Thanks!
I made a quick ~20" rectangle in Fusion with an empty 1x1" square in the middle, extruded up to 1 inch height- then import to Bambu and set that as a negative shape you can drag the “empty” square around your plate to only slice the 1x1" area you want. scale up or down as needed.
Yeah this is pretty much what I was thinking of and poorly described as a “c” bracket. Glad to know it works.
I literally just did this. I needed to test the top of a model to make sure Thor’s hammer will sit in the alligator’s head stably. As one is wont to do.
This is how I did it:
Go to the Prepare tab at the top of Bambu Studio.
Add a primitive cube to the build plate with the thing you want to partially print.
Hold [ctrl] and click on the new primitive and your object.
Right click on either object and select “merge.”
You’ll now have an assembly containing the two objects.
On the left side of the app, under the process section, change it to Objects if it’s set to Global.
You can now see each of the object in your newly created kludge.
In that list of objects select your object (not the cube).
You can now move it below the build plate level so you can start the build at the level you want.
To also chop off the top, so it doesn’t print, slice the plate and then under the preview tab select the top of slice marker. Move it down to where you want the top of your print to finish. Now right click on that position on the slice stack and pick “Add Pause.” When you print it your printer will stop at this spot.
You might be able instead add a G-Code call to BASE_CANCEL_PRINT but I’m brand new to this so have no idea if that’s even a good idea. The pause worked perfectly for me to do a quick test.
