Glossary
Layer Lines
The horizontal lines formed by the deposition of material in each layer during the 3D printing process.
Diagonal Printing
A 3D printing technique where the model is rotated on an angle, changing the orientation of layer lines from horizontal or vertical to diagonal.
Adhesion
The ability of the 3D printed layers to stick to each other and to the print bed.
Overhangs
Parts of a 3D model that extend horizontally without direct support from the layer below, requiring careful printing settings.
Support Blocker
A feature in slicer software like Cura that allows users to prevent supports from being generated in specific areas of the model.

Frequently Asked Questions
Printing vertically looks good but is weak, while printing horizontally is strong but may not look as good due to support structures or orientation.
Diagonal printing shifts layer lines to an angle, combining the aesthetic benefits of vertical printing with the strength closer to horizontal printing.
Create a small flat edge on the model by rotating it in slicer software or by pushing it slightly through the build plate to increase surface area contact.
Use a 100% cooling fan speed to ensure quick cooling of overhangs and a smaller layer height (e.g., 0.16mm) to make overhangs less aggressive.
A larger print angle generally results in a stronger part, but it also makes the print more challenging to execute successfully.
