AI Lithophane Maker

Instantly convert 2D photos into

Watertight 3D Lithophanes

Engineered for Flawless Translucency

Stop struggling with manual height maps and mesh repairs. Powered by the Direct3D-S2 engine, our AI Lithophane Maker processes volumetric depth data in milliseconds, generating mathematically perfect reliefs for SLA and FDM 3D printing.

Direct3D-S2 depth estimation for highly detailed lithophanes

High-Fidelity Depth Estimation

Our advanced AI utilizes a spatial sparse attention (SSA) mechanism to map 2048³ resolution depths, ensuring the finest tonal variations in your 2D photo translate into precise 3D relief layers.

Mathematically watertight 3D mesh ready for additive manufacturing

100% Watertight Geometry

Say goodbye to non-manifold edges. The engine generates a closed, flawless triangulated mesh that your slicer will instantly recognize, guaranteeing a 100% success rate in 3D printing.

Variable Thickness Mapping

Our intelligent thickness algorithm calibrates the optimal min/max depth ratios. This ensures maximum light transmittance and breathtaking contrast when your lithophane is backlit.

How to Create a 3D Lithophane in 3 Steps

Step 1: Upload Reference Image

Drag and drop your high-contrast 2D photo into the Neural4D studio. Images with strong lighting and shadows work best for dramatic relief effects.

Frequently Asked Questions

What makes Neural4D's Lithophane Maker better than traditional software?

Traditional software relies on basic grayscale extrusion, often resulting in jagged edges and non-manifold geometry. Neural4D utilizes the Direct3D-S2 engine to map a 2048³ resolution depth field, guaranteeing smooth gradients and 100% watertight STL files that never fail to slice.

What are the best slicer settings for 3D printing lithophanes?

For FDM printers, print the lithophane vertically (standing up) with 100% infill, 0.1mm to 0.12mm layer height, and print speeds around 40mm/s. Use a brim for bed adhesion. For SLA resin printers, print at an angle with proper supports.

What image formats can I upload?

We support standard formats including JPG, PNG, and WebP. For best results, use high-contrast images where the subject is clearly separated from the background.

Which 3D printing material works best for lithophanes?

White PLA or PETG is universally recommended for FDM printing as it offers the perfect balance of opacity and translucency. For resin, standard white or slightly off-white resins yield the most striking photographic details.

Is the AI Lithophane Maker free to use?

Yes! Free users receive 50 power credits every week, allowing you to generate and download watertight 3D lithophane STL files completely free of charge. Paid tiers offer batch generation and commercial rights.
