Most of models require support structures in order to be printed properly. In Luban, you can either use Auto Support feature to auto-generate the supports or use Manual Support feature to manually add or delete the support.
¶ Auto Support
-
Enter a proper value for overhang angle, then click Generate Auto Support.
The overhang angle in 3D printing refers to the maximum angle at which a part of the model extends outward at an angle from the vertical axis of the object being printed. The 45° rule serves as a practical guideline when dealing with overhangs in 3D printing, and it is not recommended to set the angle bigger than 50°.
The overhang angle influences how much support material is added and where. A smaller angle leads to more support. For example, at a value of 10° most of overhangs are supported, while at 90° no support material is added.
¶ Manual Support
- Click Edit > Add or Delete to manually add or delete supports. Click wherever you want the supports added or deleted, then click Done.
The purple surfaces represent the overhang area that Luban recommends to add supports.
Click Clear, all added supports will be cleared.
