Facetra is an AI-powered jewellery design workflow platform for Indian ateliers. It converts hand sketches into photorealistic renders, multi-view technical sheets, live-gold-rate Bill of Materials, and downloadable 3D meshes (GLB/STL/OBJ/FBX). Built for Jadau, Polki, Kundan, Meenakari, Temple and Rajwadi styles.

Does Facetra replace CAD software like Rhino or MatrixGold?

No. Facetra is a workflow layer that produces the reference material (renders, multi-view sheets, BOM, 3D mesh) a CAD operator uses. Your CAD bench continues to use Rhino, MatrixGold or JewelCAD to retopologize the mesh into a cast-ready model.

What jewellery styles does Facetra support?

Traditional Indian styles: Jadau, Polki, Kundan, Meenakari, Temple, Rajwadi. Modern styles: solitaire, halo, cluster, tennis, cocktail. The rendering vocabulary understands craft terms like chaton, bezel, prong, jaali, nakashi and meena work.

What 3D formats does Facetra export?

GLB (default), STL, OBJ, FBX, USDZ, GLTF and 3MF. Two quality tiers: Standard (25 credits, 4K PBR) and HD (35 credits, native 8K PBR).

How much does Facetra cost?

Credit-based pricing. Studio render 1 credit, multi-view sheet 4 credits, CAD-ready 1 credit, 3D mesh 25-35 credits. Credit packs: Starter ₹1,500 for 100 credits (₹15/credit), Studio ₹7,000 for 500 credits (₹14/credit), Atelier ₹15,600 for 1,300 credits (₹12/credit). New signups get 10 free credits.

Is my design confidential on Facetra?

Yes. Every design lives in a private per-user storage bucket. Nothing is public, nothing is shared with other users, nothing is used to train shared AI models.

Workflow Pillar

Jewellery Sketch to 3D — Production-Ready Mesh, Same Day

Sketch on one side, wax-printable 3D mesh on the other. Facetra bridges 2D → 3D for jewellery in one submission — manifold, symmetric, wall-thickness-aware. Standard or HD tier, both ready for the CAD bench or a direct-to-wax printer.

Start rendering — 10 free credits How it works

Modelling jewellery in 3D is the highest-value, highest-cost step in an atelier's design pipeline. A single custom piece — a Kundan aad, a diamond halo ring, a temple vanki — takes a CAD operator 8-16 hours in Rhino or MatrixGold, at ₹5,000-15,000 per outsourced model. For a five-piece bridal set: ₹40,000-75,000 and 2-3 weeks turnaround.

Facetra's sketch-to-3D pipeline collapses that to ₹180-300 per mesh and 3-5 minutes per generation. Upload a sketch, choose quality tier (Standard 15 credits or HD 25 credits), and Facetra outputs a manifold, wall-thickness-aware, symmetric 3D mesh in every format your CAD bench or 3D printer needs — STL / GLB / OBJ / FBX / USDZ / 3MF.

What is AI sketch-to-3D for jewellery?

AI sketch-to-3D for jewellery is a mesh-generation workflow that reads a 2D image (sketch, render or photo) and produces a full 3D mesh with correct volume, wall thickness safe for lost-wax casting (0.6-0.8mm) or DMLS printing (1-2mm), and manifold geometry (no floating faces, no non-orientable surfaces, no open edges). Unlike photogrammetry (which needs 30-100 photos) or NeRF (which produces a point cloud, not a mesh), Facetra works from a single image and outputs immediately-usable production geometry.

What Facetra's sketch-to-3D pipeline delivers

One image in — sketch, render, photo, competitor reference. No multi-view shooting required.
Six export formats — STL, GLB, OBJ, FBX, USDZ, 3MF — every retopology, print or web-viewer target
Manifold, wall-thickness-aware output — safe for lost-wax casting or DMLS 3D printing
Symmetry lock — bilateral symmetry (necklaces, earring pairs) preserved so the mesh doesn't drift
Two quality tiers — Standard (15 credits) for review, HD (25 credits) with ~4× polygon density for direct-to-print
Style-aware volume — Kundan chatons, Polki foil layers, temple nakashi relief, prong / bezel geometry all modelled correctly
Instant WebGL preview — share a link to the client to rotate the piece in-browser before manufacture

The Facetra workflow (six steps, one afternoon)

Upload a sketch (paper, tablet, or competitor reference photo).
Optional: pick style so the volume-modeller uses the right anatomy — Kundan / Diamond / Temple / …
Pick tier — Standard (15 credits) for client preview, HD (25 credits) for direct-to-wax printing.
Facetra generates in 3-5 minutes.
Preview in the browser (rotate, zoom, orbit) and download STL / GLB / OBJ / FBX / USDZ / 3MF.
Send to your CAD bench for retopology or to a wax printer for direct output.

Sample prompts to copy

Paste any of these prompts into Facetra Studio to see the style in action. Adjust weights (heavy / light), stone colours and motifs freely.

Prompt 1Sketch of a Chandbali earring pair — HD tier, Kundan style, preserve foil-backed Polki chaton depth, gold wall thickness 0.7mm for lost-wax casting, STL and 3MF export

Prompt 2Rough thumbnail of a diamond solitaire ring, cathedral setting — Standard tier, preserve prong count, knife-edge shank, GLB export for web preview and STL for wax print

Prompt 3Reference photo of a temple Lakshmi vanki — HD tier, preserve high-relief nakashi depth and uncut ruby chaton cavities, 3MF export for DMLS metal print

How much does it cost?

Credit-based pricing. Studio render 1 credit per variant, multi-view sheet 4 credits, CAD-ready view 1 credit, 3D mesh 15 credits (Standard) or 25 credits (HD). Credit packs start at ₹1,500 (Starter, 100 credits, ₹15/cr) and go down to ₹12/credit on the Atelier pack (1,300 credits at ₹15,600). New signups get 10 free credits.

Frequently asked questions

Is the 3D mesh directly castable, or does it need retopology?

Facetra's mesh is manifold, symmetric and wall-thickness-aware — usable directly for 3D-printed wax and client-approval prototypes. For high-volume commercial casting, most ateliers still run a retopology pass in Rhino or MatrixGold to optimise for their specific pipeline. The mesh saves 90% of the CAD operator's time regardless.

Which tier — Standard or HD?

Standard (15 credits, ~₹180) for client-approval preview and WebGL sharing. HD (25 credits, ~₹300) for direct-to-wax / DMLS printing where fine detail (granulation beads, jaali openwork, meenakari inlay depth) matters. HD has ~4× the polygon density.

How is this different from photogrammetry or NeRF or Meshy AI?

Photogrammetry needs 30-100 photos and produces a mesh with baked photo texture (unusable for casting). NeRF outputs a point cloud, not a mesh. Meshy AI is generic — no jewellery-native vocabulary, no wall-thickness awareness, no symmetry lock. Facetra is jewellery-specific with all three guarantees.

Does it handle articulated pieces (snake bodies, orchid stems)?

For articulated pieces, pair sketch-to-3D with Auto-Split component detection first. Each articulation segment becomes its own STL, and your CAD bench joins them with jump rings, ball chains or ball-and-socket links in Rhino / MatrixGold.

Can I generate 3D for a complete bridal set in one submission?

Yes — upload up to 6 sketches or reference images per submission. For a full 5-piece Kanjivaram temple set (vanki + oddiyanam + jhumka + kaasu malai + nethichutti), one submission at HD tier ≈ 175 credits ≈ ₹2,100. Traditional route: ₹40,000+.
