Inside DepthGen Pro
Not one model. The right one for the image.
A coin, a portrait and a logo need different depth models. DepthGen Pro reads the image, routes it, then puts the detail back. Hover a step to follow the path.
Built for work people pay for.
Every piece below starts as an ordinary image and ends as a file a machine can cut, carve or print.
Scenes are illustrations of typical projects.

Pet portraits on wood
A pet portrait starts as a phone photo. DepthGen Pro turns it into a relief a diode laser can carve.

CNC relief panels
Height maps for Aspire, VCarve and Carbide Create, or a watertight STL straight into CAM.

Lithophanes
Photo to backlit panel, sized in millimetres and exported as a clean STL.

Filament paintings
HueForge-style color reliefs planned around the filament on your shelf.

Coins and medals
The photometric relief engine rebuilds height from shading, where generic AI sees a flat disc.
How the relief engine works
Pay once. Stop renting your depth maps.
Cloud depth tools cost about $15 to $30 a month past the free tier. DepthGen Pro is $49.99, one time, with every update included.
- Lifetime licence. No renewal date, no credits, no tier that locks features later.
- Commercial use included. Sell every engraving, carving and print you make.
Your client's photo never leaves the machine.
Memorial portraits, commissioned pieces, unreleased designs. Cloud tools need them on someone else's server first. DepthGen Pro, VoxelPrime and the free tools process everything on your own computer. Depthue Studio works locally too, and uploads only when you run a cloud job or share a proof.
Offline by design
DepthGen Pro needs the internet once, to activate. Then never again.
No upload in the browser
The free tools run the AI model and file conversion on your device.
Your files stay yours
The desktop apps and free tools need no account and add no watermarks or usage caps.
Free tools
Free tools that run in your browser.
No signup, no email wall, no upload. Bookmark the ones you use at the bench.

Questions, answered straight.
What is Depthue?
Depthue makes software for turning images into physical relief. DepthGen Pro is an offline AI depth map generator for laser engraving, CNC carving and 3D printing on Windows and macOS. VoxelPrime turns images into HueForge-style color prints. Depthue Studio is a browser workspace for custom relief coins and plaques with customer proofs. The free browser tools cover depth maps, lithophanes, STL viewing, 3MF conversion and laser setup.
Is there a free depth map generator?
Yes. The Depthue depth map generator runs the Depth Anything V2 model in your browser for free, with no signup and no upload, and exports PNG and STL. DepthGen Free Edition is also a free offline download for Windows.
Do the free tools upload my images?
No. Every Depthue tool processes files on your own device. The AI model downloads to your browser once and runs locally, so photos, STL and 3MF files never reach a server.
Is DepthGen Pro a subscription?
No. DepthGen Pro is a single payment with a lifetime licence and free updates. The Windows and macOS editions are sold separately, each with its own licence.
Does Depthue sell a subscription?
No. Depthue Studio, the browser 3D workspace, starts free with 50 credits a month for cloud AI and no card. DepthGen Pro and VoxelPrime are one-time purchases.
Which file should I export for LightBurn?
An 8-bit grayscale PNG covers LightBurn 3D Sliced jobs up to 256 passes. Use a true 16-bit PNG only when the job runs more than 256 passes on LightBurn 2.1 or newer.
What is the difference between DepthGen Pro and VoxelPrime?
DepthGen Pro makes depth maps and relief meshes for lasers, CNC routers and single-color prints. VoxelPrime plans multicolor filament prints, HueForge style, with color swap heights for any FDM printer.
Make your first depth map in under a minute.
Drop a photo into the free generator. If it earns its place on your bench, DepthGen Pro takes it the rest of the way.
