Computer Vision Detects 3D Printing Defects in Real-Time
One of the biggest drawbacks of 3D printing is that you often don't know whether a part was made correctly until the job is finished. By that point, hours of printing time and expensive material may already have been wasted. Researchers at Lawrence Livermore National Laboratory are trying to change that with a new AI-powered inspection system that watches a print as it is being built, measuring every layer in real-time instead of waiting until the end.
The system was developed for direct ink writing, an additive manufacturing process that extrudes soft materials through a fine nozzle to create intricate lattice structures. These lattices are made from thin strands that must be deposited with high precision. Even small changes in filament diameter or broken sections can alter the mechanical properties of the finished part, but detecting those defects has traditionally required removing the completed print from the machine and inspecting...
