Sculpt · scale · cast
Use less gold.
Use less silver.
Cast the same design.
Send the finished sculpt. SculptScale empties it from the inside to the wall your caster asks for, keeps your surface exactly as it was, and tells you what the piece will weigh in metal before you cast it.
Your first production file is free — no card. We set your studio up by hand, usually the same working day.
One real job. Every number measured, not estimated.
453.6 g of silver became 127.0 g — at a wall you can actually cast.
Same piece in gold: 779.3 g of 22k became 218.2 g. Every figure above is lifted from that job's own report — the one-page PDF you can read below before you send us anything.
Do it on your own piece
See what your file is costing you in metal
Drop in the STL, OBJ or GLB your sculptor gave you. You get its size, its solid weight in every metal we cost, and what it would weigh hollow. The file never leaves your computer — this runs inside your browser, and this page is not allowed to send it anywhere.
| Metal | Solid, as sent | Hollow at 0.8 mm |
|---|---|---|
| Sterling silver | — | — |
| 14k gold | — | — |
| 18k gold | — | — |
| 22k gold | — | — |
| 24k gold | — | — |
| Platinum 950 | — | — |
| Casting wax | — | — |
This is an estimate from the outside of your model, not a job. It assumes the whole outer surface takes a 0.8 mm wall. Your real piece has a base that opens, places too thin to hollow, and a wall we measure on the finished shell rather than assume — which is exactly what the free first file gives you.
Why not a free hollowing tool
Making a model hollow is the easy half
Plenty of tools will empty a model for nothing, and for a plastic print that is fine. None of them can tell you what the piece will weigh in 22k, whether your chasing survived, or whether the wall they left behind is castable. You are not buying a hollow model. You are buying the certainty to cast it.

Why this exists
The metal is the cost. Everything else is rounding.
A solid silver idol prices itself before a single hour of labour: weight times today's rate. Studios know this, which is why paper cores and hand-built hollows exist at all.
Take two-thirds of that weight out and the quote drops by thousands on every piece — while the idol in your client's hands looks exactly the same, because it is exactly the same.
What no hand method can promise is that the surface you sold is the surface you cast. Most hollowing methods rebuild the whole skin in the process. Detail softens. And nobody can tell you by how much, because nothing measured it.
SculptScale carves the cavity and leaves the skin alone. Then it proves it left the skin alone.
Do the arithmetic
What would your last piece have saved?
Put in the solid weight and today's rate. The measured job above saved 72% of the metal; your piece will have its own number.
An estimate, not a quote — your piece decides the real number. Send one file on the free trial and its report gives you the exact figure for that piece, in your metal, before you commit to anything.
Pillar one
The wall you asked for — and proof you got it
Ask for 0.8 mm and you get about 0.8 mm. The wall lands where you set it, not wherever the build happens to finish.
Then it is measured on the finished piece, and the report gives you both the usual wall and its thinnest points — because the thinnest point is what fails in the kiln. An average has never saved a casting.
It measures what it made. It does not inspect your design. SculptScale will not tell you where the file you sent is already thin — checking the design itself belongs with your designer, before it reaches here.
Weights in seven materials, every time
Solid, hollow, and the percentage saved — all together, so you are not re-running anything to price an alternative. Metal only: no stones, no findings, no sprue. The hollow volume is printed too, so an alloy we do not list is that number times your own density.
Where the wall should sit
SculptScale does not pick this for you. It holds the number you give it, and tells you what it actually achieved.
The part with no workaround
Your design comes back exactly as your sculptor made it
The piece is emptied from the inside. The face, the ornament, the chasing, every mark your sculptor spent weeks on — none of it is touched, softened or redrawn.
And you do not have to take our word for it. Every piece is checked against the design you sent, and the result is printed on the report in plain words. This happens on every job, on every plan. There is nothing to switch on and nothing to pay extra for.
Anyone can promise your detail survived. The report is where we prove it.
The caster's first question
An open underside, not a decorative hole
Where the piece has a base worth opening, the underside opens along the wall's own edge — wax and resin drain and vent through an opening the shell already has, with nothing drilled through the sculpt.
Where there is no such base, it closes the shell and bores drain holes instead. Each bore is checked to confirm it actually broke through before the report is allowed to claim it. A hole that is drawn but not open is worse than no hole.
Pillar one, continued
Cut to fit the printer you own
A 300 mm idol on a 100 mm build plate is not a problem you solve by buying a bigger printer. SculptScale cuts the hollow shell into printer-sized parts with locating pins and matching sockets — casting clearance included — so the parts print, cast, and solder up in register instead of by eye.
Cuts are steered onto smooth areas and kept away from ornate bands. Before the parts are handed over, every one is checked to fit your machine, to be sealed and ready to print, and to add up to the whole piece with nothing missing between them. Joints are all-or-nothing: it places a pin and its socket, or neither.
One warning, and it is a real one. Cut placement favors smooth areas of the surface. A smooth cabochon bezel or a flat stone seat looks exactly like the kind of surface the planner prefers to cut through. SculptScale has no concept of a setting. If your piece's value is in its stones, read Fit and limits before you upload.
Pillar two
Your model can scale. Your manufacturing intent should not.
“Why can’t I just scale this in Rhino?”
You can. Every package can. That is not the hard part.
The hard part is that scaling a hollow shell scales the wall along with it. Take a 0.8 mm shell to 130% and you are casting 1.04 mm and paying for the extra metal on every piece. Take it to 70% and you are casting 0.56 mm and finding out at the kiln. A scale factor is a ratio. A wall thickness is an absolute manufacturing decision. They do not belong in the same operation, and no uniform transform can keep both.
So SculptScale refuses. In these words:
The correct order is a sequence, not a transform
Scale the solid master
To the size you need.
Hollow again
At the wall your caster wants.
Read the measured wall
On the new report, not the old one.
Re-section
Because the parts changed size too. Everybody forgets this one.
Four ways to set the size
The trade usually works between 1.5% and 3% shrinkage, and we will not guess yours. Ring sizing exists too, but it is the least developed part of the tool — read its limits before you rely on it.
Refusals
It would rather stop than guess
A tool that quietly does something reasonable when it cannot do the right thing is more dangerous than a tool that stops. Five of the stops you may meet, in the words the product actually uses.
Bigger than the machine
If a file is too heavy for the machine to work on, the job stops before touching anything, says “Nothing was changed”, and names both the numbers and the fix — in terms your designer will recognise straight away.
The current limit is published, always, on the app's live status page. Working with a very large file? Check it before you upload.
ZBrush's own format
Cut pieces cannot be capped
Two different answers
Below 0.20 mm it refuses outright. Between 0.20 and 0.50 mm it proceeds and warns, in print on the report, that the output is a reference for dies and electroforming rather than something to cast.
Most casters want 0.6–0.8 mm; Formlabs recommends 0.7 mm for castable wax shells.
Fair share, not a punishment
Every refusal is transactional
A rejected job leaves no half-finished state behind: no partial file, no consumed export, no version you have to go and delete. The message names the fix, and your previous version is exactly where you left it.
Every message above is the product's own text, checked 13 August 2026.
Records
Nothing destructive happens without a name on it
Scaling, hollowing and ring-sizing each require a named human approval before they run. Every step becomes its own immutable version with its lineage recorded, so “which file did we actually cast” still has an answer six months later.
There is no per-seat licence to buy — a studio gets one shared access code, created by us. But approvals are still signed by the person who gave them.
The proof travels without you
Every piece we process comes with its report
One page. One PDF. Forward it to a client or a caster who has no account, no code and no interest in learning your software — it is understood in a minute.
It opens with what matters to the quote: the weight before, the weight after, and what you saved. Then the wall it measured, the verdict on your detail, and the parts if the piece was divided. At the bottom is Notes, where anything the job flagged is printed in full.
Notes cannot be switched off. The report covers the piece that was processed, and it carries what the job actually found — including anything that went wrong. Hiding the honest part of the output would be the wrong business to be in.
Fit
Who this is for, plainly
Built for
- Silver and gold idol and murti studios casting solid metal
- Sculptural and relief jewellery — pendants, plaques, signets, temple work
- ZBrush and Blender sculptors who hand meshes to a caster
- Studios on a small build plate who need pieces that do not fit on it
- Medallions, trophies, plaques and commemorative pieces in precious metal
Not built for
Set-stone CAD jewellery. SculptScale does not know what a stone is. It does not find a prong, a bezel, a pavé field or a girdle; it will not protect a seat; its weights are metal only; and its cut planner treats a smooth bezel or a flat seat as a good place to cut. If the value of the piece is in its settings, that piece belongs in your CAD package.
Rhino and MatrixGold files. The engine is mesh-only —
there is no CAD kernel in it at all — so .3dm,
.step and .iges are not read. Export STL or OBJ
first and the rest works normally.
Pricing
One cast-ready file can pay for a year of this.
A cast-ready file is one finished, manufacturing-ready set you take away. If your sculpture comes back divided into six printable parts, that whole set is still one file, not six. Downloading it again later is free forever, a refused job never costs you one, and looking, checking, scaling and previewing never count.
Put it against the metal. That one Ganesha kept 326.6 g of sterling out of the crucible — and had it been 22k gold, 561 g. One file, one piece. If it will not pay for itself on your first piece this is not the tool for your work, and your free file will show you that before you have spent anything.

Ways to pay
Card and UPI through Razorpay, or an invoice from us directly. You are billed in rupees by Magnitude Intelligence, our Indian entity. If checkout is not switched on for your workspace yet, the app says so plainly rather than failing — and we will raise an invoice the same day. Prices exclude GST; GST is added at checkout once registration is active, and until then you are invoiced at the price shown.
Card through Stripe, or an invoice from us directly. You are billed in US dollars by Intellectz LLC, our US entity. If checkout is not switched on for your workspace yet, the app says so plainly rather than failing — and we will raise an invoice the same day. Prices exclude any sales tax or VAT, which is added at checkout where it applies.
Every file you have paid for stays yours, including after you stop paying. That is in the terms, in the same words.
Test before you pay. Your first cast-ready file is free. And if a paid file does not pass SculptScale's own stated checks, we replace it or refund it — see Refunds.
Getting started
Send us one file and see the report
There is no self-signup, and that is deliberate for now. We create each studio's access code by hand, usually the same working day, so that someone has actually looked at what you are trying to make before you spend money on it.
One code per studio — not per person. Your first production export is free, and it comes with the full report for that piece.
What happens next: we read it, we create the code, and we email it with a two-minute note on where to start. If your work is mostly set-stone jewellery we will tell you honestly that SculptScale is not built for it, rather than take the money. What you send us is covered by our privacy notice.
Questions
Before you ask
Does this replace ZBrush?
No, and it is not trying to. SculptScale takes a finished sculpt and prepares it for manufacture. The sculpting stays where it belongs. There is an OBJ round-trip precisely so you can go back to ZBrush and return.
Which files can I upload?
STL, OBJ or GLB for meshes; PNG, JPG or WEBP for sketches. Not ZTL —
run Decimation Master and export STL or OBJ. Not .3dm,
.step or .iges: the engine is mesh-only. Note that
everything is converted to STL on ingest, so keep your master.
What happens to my design's surface?
Nothing. It comes back exactly as it came in — only emptied from the inside. Every piece is checked against the design you sent, and the report says plainly whether anything changed.
How much metal will I actually save?
On real jobs it has run between 70% and 87% of the metal inside the piece — the exact figure depends on the piece and the wall your caster wants. Nobody has to take that on faith: your free trial piece comes with its report, so you see the real number for your own work first.
I work in gold, not silver.
Every job prints the weight in sterling silver, 14k, 18k, 22k and 24k gold, platinum and casting wax — solid and hollow, side by side. So the saving is in your metal at your rate, not converted from someone else's.
How big a piece can it handle?
It depends on the machine's memory, so rather than guess we publish the live figure on the app's status page. If a file is too heavy, the job stops before touching anything and tells you exactly what to ask your designer to send instead.
Does the report cost an export?
No. The report belongs to the piece that was processed and comes with it. Previewing, validating and scaling do not cost an export either. You are charged when you take away a manufacturing file.
Is there a trial?
Yes — one production export, free, with the full report for that piece. Ask for a code and it is on your workspace when you sign in.
What this does not replace. SculptScale runs manufacturing-aware checks on geometry. It is not a substitute for your studio's final CAD review, your caster's judgement, or your own inspection of a piece before it reaches a client. It measures what it built and reports what it found, including what went wrong. The decision to cast stays with you.
