Hi3D adds one-click part splitting for printable AI models

The gap between a flashy AI render and a file that survives the slicer is where a lot of maker time disappears. Hi3D pushed straight at that pain point with a new Maker toolkit update centered on Print by Parts, a one-click workflow that splits a character model into printable pieces and adds connectors for assembly.

The expansion went public on June 11, 2026, and Hi3D’s own product pages now frame the feature as a print-prep tool rather than a pure image-to-mesh demo. The platform says the split happens automatically so models can fit inside build volume, avoid unprintable overhangs, and reduce the support scars that often wreck a finished figurine. That matters because the usual frustration is not generating a cool shape, but getting it into a form that can actually be sliced, printed, and assembled without a separate CAD cleanup pass.

Hi3D also added Auto Connectors, which generate alignment joints at split points so users do not have to build pegs or sockets by hand. The company says the system aims for cleaner, watertight meshes, a detail that should cut down on the repair work many print files need before they ever reach a slicer. Hi3D supports downloads in .glb, .obj, and .stl formats, keeping the output pointed toward the tools and slicers hobby users already know.

Behind the scenes, Hi3D says the platform is powered by Math Magic’s in-house Sparc3D and Ultra3D models. Its docs describe the service as an AI image-to-3D tool that can generate high-precision models from uploaded 2D images, and the company says the workflow is built for 3D printing, among other uses. Hi3D’s use-case page says it is trusted by more than 1,000 makers, small business owners, and 3D printing enthusiasts, which signals a push beyond novelty output and toward repeatable production work.

The commercial side is just as telling. Hi3D says free work is publicly accessible under CC BY 4.0, while private licensing is available for private storage and protection around commercial use. Its pricing documentation lists segmentation as a paid API capability and shows example generation tiers at $0.50 and $0.40, underscoring that the company sees printability cleanup as part of the product stack, not an afterthought. With its June 10 Split-to-Print Guide and Connector Setup Full Tutorial, Hi3D is clearly trying to make the hardest part of AI printing less about fixing broken geometry and more about getting from screen to build plate in one pass.
