Built for the process

Adjust stiffness and add practical features like handles to create masks suited to real production workflows.

The challenge

Masking parts for shot peening, blasting, or coating by hand is time-consuming and inconsistent. Off-the-shelf masks rarely fit complex geometries, leaving gaps that expose surfaces that should be protected.    

Design automation

Design automation reads your workpiece geometry and generates a mask body that conforms precisely to every surface, hole, and thread you need to protect. Alignment keys and retention features are built in automatically, so the mask stays exactly in position during treatment. Pull tabs and handling features can be added in a single click, making removal fast and safe without damaging the part.

The result

The Masking App in the Additive App Suite is a fast, browser-based tool that turns your workpiece geometry into a precise, reusable mask — with automatic surface conforming, built-in retention, and easy removal features ready for 3D printing in minutes.
