SelfCad

SelfCAD is a browser-based and downloadable 3D design program that brings modelling, sculpting, rendering and 3D-print slicing together in a single application. Most 3D workflows require stitching together separate tools — one for precise modelling, another for organic sculpting, a third for preparing files to print — each with its own interface and file conversion steps. SelfCAD collapses that chain into one program, which is its central selling point and the reason it has found a following in education and among hobbyist and prosumer makers. The modelling toolset covers the standard operations: primitives, extrusion, bevelling, boolean operations, lofting, revolving, mirroring and deformations, along with sketching and drawing tools for building profiles from scratch. A freehand sculpting mode with brushes for pushing, pulling, smoothing and inflating geometry sits alongside the precise tools, so users can move between engineering-style accuracy and organic shaping as a project requires.

Because it runs in a web browser, SelfCAD requires no installation and works across operating systems and on relatively modest hardware, with a desktop version available for those who prefer it. Projects are saved in the cloud and accessible from any machine, which suits classroom settings where students move between computers. The built-in renderer produces presentation images without exporting to a separate visualisation package, and the integrated slicer generates G-code for 3D printers directly from the model, removing the usual round trip through Cura or PrusaSlicer. Interactive tutorials and a step-by-step learning system are built into the interface, and the company has invested heavily in curriculum material, making the tool a common choice for schools, STEM programmes and self-taught beginners. Export formats cover the common standards including STL, OBJ and others needed for printing and downstream use. SelfCAD is positioned as an affordable alternative to professional CAD suites, with paid plans starting from around USD 14.99, a free version available for basic use, and a free trial for the paid tiers. It is best suited to education, hobbyists, makers and light commercial modelling rather than production engineering.
