3D printing is now one of the technologies that is developing for all fields, especially in the automotive sector, the existence of 3D printing is very helpful for making the desired designs and 3D printing has a big role to meet the needs of several workshops, because with this technology The concept created can be influential to support the neatness of the workshop, especially in storing tools. One of the benefits that can be generated from this technology is to make parts that can help tidy up the tools in the workshop. Of course, the concept and design that is made must be thought of beforehand, its usability and function so that it can function properly for the workshop itself. Therefore, this technology has become an opportunity for solutions to solve problems so that the manufacture of products that will be used for workshops is greatly helped by the existence of a 3D printer. The results achieved are the difference in dimensions on the key chain prototype which may be due to the difference in the depreciation value of the material used when the material becomes solid. 3D Printing machine is very helpful in making prototypes when the product will be made in bulk quantities. And can also be used to make parts that have complex shapes.
