About ColorStack
ColorStack is a free, browser-based tool designed to transform ordinary 2D images into stunning, color-layered 3D printable files. As a modern, accessible alternative to HueForge, our platform enables creators of all skill levels to generate physical, photorealistic prints directly from their photos.
How It Works
Our engine analyzes your uploaded image and mathematically computes a topographical mesh based on luminance and color mapping. By assigning specific layer heights to different physical filament colors, the resulting 3D object utilizes optical blending—a process where thin layers of plastic transmit light from the layers beneath them—to create a wide gamut of perceived colors.
