An MIT team presents VisiPrint, a system that solves a common problem in 3D printing. Current software focuses on geometry but leaves the final appearance to chance. This causes unpleasant surprises when unmounting the piece, with unwanted colors or shines, leading to reprints and waste. This tool generates a photorealistic preview before printing.
How the neural network behind VisiPrint works 🤖
The system uses a neural network trained with thousands of data pairs. Each pair consists of a 3D model and a photograph of the already printed and finished piece. The AI learns to correlate the geometry of the digital file with the real physical result, considering how light interacts with the layers, surface texture, and color effects. This way, it can predict and render a very accurate image.
Goodbye to the surface finish lottery 🎲
We can finally say goodbye to the excitement of not knowing what we'll get. That grainy texture you didn't expect, or that ghostly shine in a weird spot, stopped being a surprise and became a disappointment. Now, instead of relying on faith and luck, we will be able to see the future clearly. An advance that might take a bit of the fun out of the process, but will save us kilograms of filament and hours of reprocessing.
