Lifecasting:

Blender - mods

If you model your part in blender, you should start with a cube 49.3333 m x 44 m x 18.5 m in size.

Hmm....I was just about to document the blender - mods - workflow when this happened: If the roughing doesn't enter in a hole and the finishing is 5 mm deeper, the tool breaks.

Let's use Fusion 😒

Fusion

Extrude a box 49,3333 m x 44 m x 18,5
Create a cavity 2mm from the edge, 15,5 mm deep. If you give the sidewalls a 10° draft angle, you won't be able to hit it with the 1mm mill.

Place your svg (imported with the right scale factor of 3,77957518)

and extrude it.

In the Manufacturing workbench we create a setup, with a stock of 0-offset and the origin bottom-left at the upper corner:

For the roughing I use "Adaptive Clearing" with the following settings:

For the finishing I use Parallel:

Total time is 23:27
