Quick Tip: How to easily hollow a model with Pepr3D

Pepr3D is free software that is intended to turn a single-colour object into a multi-colour object using face painting.

But you can use it also to hollow a model for SLA printing:

• first import your object
• you can add drain holes with the "Brush" tool (optional):
• select the bush tool and the second colour
• double click or drag the "Size" option to adjust the size of the holes
• paint the holes on the bottom of your object

• go to the "Export Assistant" tool

• in most cases, we need the "relative to SDF" option for clean results
• deselect the second colour
• Set the wall thickness by the "Depth" option
• "Update extrusion preview!" and readjust if necessary
• "Export files" if you are happy with the result

It is easier to use than Meshmixer but also a bit buggy and needs a lot of time for complex objects. But it doesn't crash (unlike Meshmixer).
