So far, you’ve learned how to create and refine your 3D models in Blender. But design is only half the journey — the real magic happens when your digital model becomes a physical object through 3D printing.

This lesson will take you behind the scenes of that transformation. You’ll discover how a slicer software converts your design into machine-readable instructions (G-code) and how printers build the model layer by layer.

You’ll learn to adjust print settings like layer height, infill density, and supports — which determine the strength, finish, and speed of your print.
