Opel uses 3D printers to create assembly tools for its models

The arrival of 3D printers has been a real revolution for many sectors. The automotive industry has not been left out and has begun to actively use them in car manufacturing. No, for now printed elements are not used in the final finishes, but tools are printed that are indeed used in the manufacturing of cars.

The production of these parts used for marking logos, fitting chrome elements to the bodywork or helping with the fitting of the windscreen. These are parts whose cost has been reduced thanks to 3D printing, and which are also easier to use, thanks to their lower weight.

In total, 40 parts between templates, guides and other types of auxiliary tools are used, which emerged during the development of the Opel ADAM ROCKS, which will soon be available at Spanish dealerships.

With the help of these 3D printers, the brand’s engineers can manufacture any part they need at any moment and if it does not fit what they require, they can make whatever modifications they want with just a few clicks on the computer. The new part is ready for use in a few hours, compared to the costly previous process, which required waiting several days after each modification.

The printing process uses layers of molten plastic, which accumulate in layers of 0.25 mm until they take the desired shape. The gaps and protrusions are filled with a filler material by the printer and then removed in a later process. If a part is taller than normal, it needs to be supported, so those support pieces can be removed once the plastic hardens.

Previously, guides and moldings made of plaster and ground resin were used. With the use of 3D printers, the parts are ready in just 8 hours and are 90% cheaper and up to 70% lighter.
