Need to edit an STL without CAD? SliceFoundry’s conversational refine flow lets you change dimensions, thicken walls, add mounting holes, and remix printable solids with plain-language prompts — building on the previous version instead of regenerating from scratch.
Most AI generators start over every time. SliceFoundry keeps context so “make the hole 6mm” and “add two M3 countersinks” update the part you already have.
A great STL is only the start. Refine wall thickness, mounting holes, and fit with plain-language follow-ups — "make the hole 6mm", "thicken the walls", "add a cable pass-through". Every iteration builds on the last until the part prints exactly right.

When you'd rather design a part precisely by hand than generate it from a prompt, Draftr is a desktop CAD application for Windows and macOS that combines AI with organic parametric CAD in an IDE-like workspace. It pairs a full parametric toolset — sketches, pads, pockets, fillets, chamfers, patterns, and threads — with natural-language AI commands, then exports print-ready STL files (and supports STEP-oriented CAD workflows). It's the natural next step once you outgrow prompt-based generation and want precise, editable, parametric models. Learn more at draftrcad.com.
