Constructor AI is now live as a free public test version, running directly in the browser with no CAD software install required. Founder Michael Bender’s pitch: describe the part you need, give dimensions and requirements, and the tool walks you through construction, generates a 3D model, and exports an STL, skipping the step where a beginner has to learn a parametric CAD interface first.
The current build does more than generate from scratch. It imports and edits existing STL files, in both ASCII and binary format, and lets users extend or modify a model before re-exporting it. It handles multiple workpieces at once, with positioning and rotation controls, hole and geometry edits, and functions for connections and guides between parts. Image, logo and lithophane processing is listed as still in testing.
The tool also goes past modeling into print prep: it takes printing parameters and material into account to generate G-code, with extra print functions for what TCT describes as “supported printers,” though the article does not name which machines or slicers are covered.
Bender is explicit that this is not a finished product. The goal is to surface real-world use cases and weak spots through built-in live support feedback, with lessons from earlier public tests already folded into the current version. The long-term aim, per the announcement, is letting anyone with a printable-part idea skip CAD training entirely.
No pricing for a future paid tier, file format limits beyond STL, supported printer or slicer list, output accuracy figures, or company backing details are given in the source. Whether G-code output has been validated against real prints, and on what hardware, is also unstated.
