Manufacturers are using 3D printing technology to print full automobiles faster than traditional factory assembly methods

Researchers at Wake Forest Institute for Regenerative Medicine have printed "human-scale" 3D scaffolds that are able to be filled with human cells. According to Anthony Atala, who led the study, these printed tissues could one day be used to replace injured tissue in humans.

Custom jigs, fixtures, and other tooling once required for a single car component, especially when high-performance machines, necessitated an array of bespoke tools, increasing expenditures while making the process as a whole more difficult. Now, the automobile industry is increasingly using 3D printing to significantly shorten design times and lead times on new car models.

A group of scientists in Amsterdam enabled the creation of chocolate - including fillings and outer shells with 3D printing. Replica cakes can even be printed using machines that deposit layers upon layers of chocolate in any kind of design you like.

Instead of incurring exorbitant repair costs or throwing away a mostly working device because of the loss or breakage of parts, one manufacturer has turned to the 3D printing of spare parts to reduce costs and productivity. They are spending less today making the spare parts and the machines are back in use faster.
