This paper presents the methods of manufacturing devices used for the fabrication of parts in the automotive and medical industries, manufactured by 3D printing. In industrial drive technology, the automotive industry and other similar industries, it is necessary to use devices for orienting and fixing the parts to be manufactured in order to obtain the finished product.In the final stages of manufacturing and beyond, it is necessary that the devices are very reliable, to present a good condition of their surface so that there is no damage to the parts that will come into contact with them. In this respect, this paper presents devices for orientation and fixing of parts and finished products, devices that have been obtained by 3D printing, from recyclable materials, with low weight and surface condition and high dimensional accuracy. In order to improve the surface of the active part of the devices, after 3D printing, they were finished using CNC milling machines, thus achieving surface finishes of the order of those achieved by grinding operations. These devices were also validated by finite element analysis and then manufactured and introduced into the production line, and have been in use for about 2 years without any problems in use.
