Editorial interest 82/100 Selection signal · not a rating of the site

A browser-based CAD workspace for repairing meshes, checking printability, creating lattices, and preparing additive-manufacturing builds.

Landing page captured for the 2026-10-05 issue.

For: Engineers and teams preparing parts for additive manufacturing
Worth noticing: Its wall check reports sampled thickness, explicitly not an exact minimum; build nesting uses bounding-box layouts.

Field notes

The feature list separates free, sign-in, and PRO tools, with TPMS lattices and variable-density struts among the PRO items. Its stated scope excludes parametric modeling, slicing or G-code, finite-element simulation, and support generation, which helps set expectations for a specialized preparation workspace. The site also distinguishes geometry results from ANN unit-cell estimates in its lattice example.
