Open the downloaded Moldboxer DMG.
Setup
First Mold
Settings stay in the right sidebar, while the header updates with the actions available at each stage.
Start a clean project with New and choose the mold type. Moldboxer opens the file browser automatically, so select your model file to import it; then adjust the mold settings in the right sidebar.
After import, the header action changes to Generate Mold. The first time you generate, Moldboxer asks you to sign in; finish login and continue from the same project.
When the mold system is generated, the Export button appears. Use it to export every generated object as an STL, ready to import into your slicer and print.
Mold systems
Press New to compare six workflows: Adapted Box, Tray Box, 2-Part Silicone, Inner Cavity, Direct-Mold Open Base, and Direct-Mold Top Funnel. Choose the system that matches how your part will be cast and released.
Settings
The right sidebar groups wall thickness, detail, safe processing, box splits, channels, base, funnel, clamps, and casting options. These controls stay visible while you work with the model.
Advanced mode
Enable Advanced Mode in General settings to split mold generation into two deliberate steps. Build Box creates editable mold components; adjust their placement and settings in the viewport, then Confirm to generate the finished mold system.
Creates the initial mold components so you can inspect and customize their placement before final generation.
Finalizes the customized components into the complete mold system. When processing finishes, Export appears in the header.
