An idea, spoken. A jewel, ready to make.
Not just another image generator. From conversation to specification-backed designs: printable 3D files same-day for physical validation, followed by casting-ready files straight to production.
Limited first partner intake · Priority for designers, brands, and workshops
Three steps from idea to production
Idea to sketch
Speak the idea; receive a sketch, complete with its production specification.
Sketch to preview
One click turns the sketch into renders and on-model previews.
Preview to 3D file
Confirm the preview, and export a production-ready 3D file for the workshop.
One specification, uniting three stakeholders
Jewelry Designers
Delegate intricate organic forms and pavé distribution to the engine; keep structural limits and gem dimensions in the spec. Revisions adjust parameters, not starting from blank canvases.
Bespoke Boutiques & Brands
Swap center stone cuts or resize shanks directly in front of the client. Photorealistic renders, on-model previews, and geometry-derived gold quotes update on the fly, locking in deposits.
Casting Workshops & CAD Modelers
Receive files that carry verified dimension chains: exact metal volume, prong diameters, and wall thickness noted. Pre-validate with fast 3D prints before committing to expensive rubber molds.
One engine. Every piece producible.
Every design carries its production spec
A mulapis design is more than an image. Metal, stones, dimensions and quotation are generated alongside it, so every piece is ready to be made.

Generation is not production
AI can draw an intricate jewel in minutes, but casting metal and setting stones securely requires manufacturing checks. mulapis reviews every piece item by item, automatically regenerating anything off-spec.
- 01
Prong integrity
Prong cross-sections stay above casting minimums, with a secure load path from stone to mount.
- 02
Dimension chain
Center stone, seats, and ring size constrain one another, checked item by item to ensure fit.
- 03
Mold release
No sealed cavities or deep undercuts, with openwork designed to leave room for finishing tools.
- 04
Wall thickness
Every wall exceeds casting minimums, keeping gold weight and material cost under control.
- 05
Setting match
Pavé spacing, halo seats, and prong counts match the stone specification exactly.
Approved, then straight into physical reality
Image generation is easy; manufacturing delivery is the moat. mulapis enforces a rigorous two-stage workflow: print physical prototypes immediately to confirm fit and ergonomics, then hand over casting-ready CAD masters with volume-derived gold weight.
Export watertight, manifold mesh files the same day a design is confirmed. Print in resin to check ring size, prong posture, and gemstone proportions on the finger before cutting metal.
Foundry-grade geometry with calculated metal shrinkage tolerances, prong offsets, and geometric gold weight. Opens seamlessly in Rhino and MatrixGold with zero remodeling from scratch.
Why generic AI art models fail in jewelry manufacturing
Midjourney generates pretty pixels with zero physical awareness; traditional CAD requires steep learning curves. mulapis embeds foundry engineering rules directly into generation.
| Comparison Dimension | Generic Image AI (Midjourney/Flux) | Traditional CAD (MatrixGold/Rhino) | mulapis Atelier Engine |
|---|---|---|---|
| Nature of Output | 2D flat illusion, zero physical depth | Manual point-by-point surface modeling | Generative form bound to engineering spec |
| 3D Print Validation | Cannot export, or meshes are full of non-manifold holes | Requires days of drafting before first print | Same-day watertight STL/OBJ ready to print |
| Casting File Delivery | Completely impossible for investment casting | Requires senior CAD technician hours | Direct 3DM/STEP foundry-ready masters |
| Gold Weight & Pricing | No geometric volume, pure guesswork | Calculated only after complete 3D model | Real-time weight & quote calculated from geometry |
| Revision Flexibility | Re-rolling prompt scrambles all design details | Changing one stone size breaks the entire shank | Localized parametric lock (resize ring, stone stays) |
Based on World Gold Council trends and atelier interviews: physical print validation cuts mold-making trial-and-error costs by over 60%.
The image is half the work: production is the finish line
Why general-purpose image models stop at the picture, and how an orchestrated engine carries a design through specification, verification and 3D output.

Muses and lapis
The name mulapis joins the Muses, goddesses of art and creation, with lapis, the Latin word for stone. Every jewel begins with a conversation.
