Boeing whats to 3-d print intricate metal parts in mass production with the help of HRL laboratories. Airbus installed a 3d printed bracket to its wings. Strong alloy 3D printing of parts is now possible. Citrine Informatics ML software combines knowledge of chemistry with alloys to figure out what materials should be used for strong alloys. Citrine engineers had over 10 million possible powder combinations for strong alloy. Citrine used machine learning predict successful combinations to test. The software was given parameters of the wanted material. The neural network was taught rules of physics and chemistry. Cintrine software predicted what atoms to add to their alloy to improve weldability. 100 powder compositions results from running the software. Each involved the powder being welded by a laser, layer upon layer, into a 3D part was produced.

New neural network hard is here allowing for contineous learning code name "ordinary differential equations". neural networks can now move from discrete steps to continueous.
