How does it work and what are the different 3D printers available? At its core, 3D printing works on the basis of additive manufacturing. Apart from rapid prototyping, 3D printing has produced custom prosthetics, jewellery, film props and art. Let’s find an answer to the question “How does 3D printing work?”. Speed and accuracy are low compared to other 3D printing technologies. Unlike the processes discussed so far, powder bed fusion does not involve the deposition of a heated material or adhesive to form the print. Because the metal isn’t melted but bonded at specific points, these printers use significantly less energy than other types of 3D printer.
