Most 3D-printed objects are prototypes or one-off creations, in large part because 3D printing is more finicky than traditional manufacturing. Because the process works by adding layers of material atop each other, subtle changes in temperatures or material quality can result in imperfections and hours of lost work. Inkbit, a Boston-area 3D printing company, is using machine vision and artificial intelligence to help its equipment course correct. Javier Ramos, co-founder and director of hardware at Inkbit, said Inkbit's machine vision technology instantly scans the objects it prints, relying on AI to correct for any mistakes made. He imagines a future where Inkbit's tech is used on every factory floor, printing out millions of products more cheaply -- and faster -- than traditional manufacturing processes ever could.

Objects made with 3D printing can be lighter, stronger, and more complex than those produced through traditional manufacturing methods. But several technical challenges must be overcome before 3D printing transforms the production of most devices. Commercially available printers generally offer only high-speed, high-precision, or high-quality materials. Rarely do they offer all three, limiting their usefulness as a manufacturing tool. Today, 3D printing is used mainly for prototyping and low-volume production of specialized parts.
