ShapeCraft is for making real things: a part for your 3D printer, a box for your electronics, the bracket you've been meaning to design for months. You don't need to be an engineer, and you don't need to sign up for anything.




The best 3D Printing alternative to Autodesk Fusion is SketchUp. It's not free, so if you're looking for a free alternative, you could try OwlCAD or Shapr3D. If that doesn't suit you, our users have ranked more than 50 alternatives to Autodesk Fusion and many of them are 3D Printing Tools so hopefully you can find a suitable replacement. Other interesting 3D Printing Tool alternatives to Autodesk Fusion are Autodesk Tinkercad, meshmixer, Microsoft 3D Builder and FreeShape.

FormaCAD is a free, open-source (GPL-3.0) parametric CAD application for the desktop. Models keep named parameters, bodies and a feature history with suppression and rollback, and geometry is built with the OpenCascade kernel.




Free browser-based 3D editor with a Blender-style interface — model, sculpt, animate, rig, render and export, with nothing to install.



Web app for transforming SVG vector designs into STL and DXF files, enabling efficient fabrication of 3D printed LED channel letters with acrylic fronts, PVC bases, nesting features, project export, and a visual 3D preview for streamlined sign production.

Local-first parametric CAD for Windows with an AI design assistant. Free basic tier, $10/month full. Your files stay on your machine.



Designing your own 3D models no longer has to feel complicated or time-consuming. With our online creation platform, anyone can design, personalize, and export 3D printable files directly in the browser.


3D mesh editor for iPad and iPhone — built for makers, 3D printing enthusiasts, and anyone who needs to fix or modify 3D models on the go.




Rig Cad is browser-based parametric CAD for building, configuring, and exporting editable 3D models. It combines several geometry kernels in one readable project tree: solid CSG, NURBS surfaces, meshes, and implicit signed distance fields, so smooth blends and hard boolean...




StlFixTool converts and repairs 3D and CAD files in the browser — STEP to STL, STL to STEP, OBJ and 3MF in both directions, and GLB/GLTF to STL, plus mesh repair for holes, non-manifold edges, duplicate faces and inconsistent normals.



Browser-based parametric 3D model generators for makers. Turn any STL into a printable mold, or make cutters, nameplates and stamps — no CAD, no signup.



Open-source tool that turns STL, OBJ and PLY meshes into editable CAD: STEP files with real planes, cylinders, cones, spheres and fillets, plus CadQuery, OpenSCAD and FreeCAD scripts with named parameters. CLI and MCP server.
