Generative Assembly is SliceFoundry's workspace for multi-part 3D print projects. Instead of generating one isolated model, you organize a project into parts, describe each piece in plain language, and iterate until the set fits together — with live previews as generation progresses.
It's built for makers who need more than a single STL: enclosures with lids, bracket kits, fixtures with mating pieces, or any project where several parts belong in one design session. First-time assembly users also get welcome tokens so you can try the editor without buying credits up front.
A great STL still needs good print settings. SliceFoundry also generates slicer profiles for your specific printer and filament, so you don't lose the AI advantage at the slicer step. If your first print struggles, the Fix My Print assistant diagnoses the failure and suggests corrections.

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.
