Alternatives to SelfCAD
Browser-based 3D modeler that combines mesh editing with basic slicing tools. The listings below can replace it for an important use case. Each note says what changes if you switch.
The original
SelfCAD
Browser-based 3D modeler that combines mesh editing with basic slicing tools.
Replacements
Listings that take over the same core job as SelfCAD.
Tinkercad
Create simple 3D designs and explore electronic circuits in a browser.
Tinkercad is a free browser tool with approachable shape-based modeling plus circuit and coding activities, but it has no built-in slicer for print preparation.
SketchUp Free
Browser-based 3D modeler that offers an easy start into 3D design.
SketchUp Free is a beginner-friendly browser 3D modeler, but it has no slicing tools and its desktop apps require a paid plan.
Womp
Browser-based 3D modeler with squishy SDF-style geometry and simple materials.
Womp is a freemium browser modeler using SDF-style geometry for organic blended shapes, with no built-in slicer and less precision for mechanical tolerances.
MatterControl
Open-source desktop app for designing, slicing and controlling 3D prints on Windows, Mac and Linux.
MatterControl is a free, open-source desktop app for Windows, macOS and Linux that combines design, slicing and printer control, though its design tools are simple.
FreeCAD
A parametric 3D modeller for real objects: design by sketching constrained 2D shapes, then change the parameters later.
FreeCAD is a free, open-source parametric desktop modeller for Windows, macOS and Linux aimed at parts for machining or 3D printing, with a longer learning curve.
Blender
The free 3D creation suite: modelling, sculpting, rigging, animation, simulation, rendering, compositing and video editing.
Blender is a free, open-source desktop 3D suite for Windows, macOS and Linux covering modelling through rendering, with no slicer and a much longer learning curve.
Also worth comparing
These listings name SelfCAD as their own alternative, so the relationship runs both ways.
3D Slash
A beginner-friendly 3D modeling tool where you shape models by carving and adding blocks.
SelfCAD moves you to browser-based mesh editing with basic slicing built in, so print preparation happens in the same tool, though performance depends on the device and browser.
Similar software
Related functionality, not a direct replacement.
MeshLab
The standard tool for cleaning up messy 3D scan data: fill holes, remove noise, simplify and convert between mesh formats.
Onshape
Fully browser-based parametric CAD platform with real-time collaboration.
OpenSCAD
A 3D modeller you write rather than draw: a script describes the object, and the program compiles it into a solid.
Meshy
A web-based AI generator that turns text prompts or images into textured 3D models.
Manyfold
Self-hosted web app for organising, previewing and sharing a library of 3D print files.
