Technology & Products
Key Products
print3dgs platform — full-color 3DGS (3D Gaussian Splatting) volumetric reconstruction and physical 3D printing service; transparent resin cube keepsakes containing reconstructed 3D scenes/objects
Technological Advantage
Proprietary 3DGS-to-physical-printing pipeline; DreamPrinting voxel printing primitive technology (SIGGRAPH 2025 Best Paper); Poxel framework for RGB-to-CMYKWCl color space conversion for full-color 3D printing; deep expertise in NeRF/volumetric reconstruction from academic research
Differentiation
Value Proposition
End-to-end full-color 3D scanning and printing service using smartphone photos/videos, AI-powered 3D Gaussian Splatting reconstruction, and full-color UV resin 3D printing to transform memories into tangible physical objects.
How They Differentiate
Combines cutting-edge 3D Gaussian Splatting (3DGS) volumetric reconstruction with full-color UV resin 3D printing in a consumer-friendly pipeline; requires only smartphone photos/videos as input; CEO's SIGGRAPH 2025 Best Paper-winning research (DreamPrinting) on voxel printing primitives underpins the technology
