Cutting your print

[XieDuke 0]

I'm new to 3D printing. I'm trying to cut the top portion of an item off before slicing. Is there a way to do that?

You can try but it may have side-effects that you don't want.

Select your model and then:

• On the left toolbar (the bottom button if you have no plugins running) is the Support Blocker tool.  Click on that and then click somewhere on your model to leave a blocker in the scene.
• With the blocker selected use the Scale and Move tools to make the block the size you want and in the location you want.
• Back on the left toolbar, the button above the Support Blocker button has the Per Model settings.  Click on it.
  • The second button from the right is "Modify Settings for Overlaps" and that's the one you want.
• Now the Support Blocker is a Mesh Modifier and by setting it to act as either a "Cutting Mesh" or an "Infill Mesh" it can do different things dependent on the settings you pick for it.

Keep in mind that you are not altering the model, you are changing what happens in the over-lapped portion of the model.  That is not the same thing.

Using Support Blocks as Mesh Modifiers takes some practice (that's my official under-statement of the day).
