Formsmith releases SketchForge, an open-source browser CAD tool for 3D printing

Formsmith has released SketchForge, a free, open-source browser-based 3D design tool aimed at creating simple parts for 3D printing. The tool is positioned as an alternative to Autodesk Tinkercad rather than a replacement for broader CAD platforms such as FreeCAD or Fusion. SketchForge lets users create and edit shapes, add holes, group solid bodies and cutouts, and export models without requiring an account or cloud connection. It supports STEP import and export alongside STL and OBJ, saves projects locally and automatically, and offers Docker-based self-hosting for FabLabs and other local deployments.

The release addresses a practical gap between beginner-friendly modeling and the more demanding workflows of full CAD systems, particularly for FDM/FFF maker use where fast iteration on simple functional parts matters. Its editable chamfers and fillets, plus planned improvements to boolean operations, precision tools and measurement functions, are relevant because these are the features that determine whether a simple modeler remains useful beyond first-time users. Open source and local storage may appeal to schools, makerspaces and users who want a lightweight tool without account administration or cloud dependence. The practical test is whether Formsmith can turn early feedback from Tinkercad, slicer and maker users into a reliable workflow for printable-part design.
