Prototyping is a major application of 3D printing in the automotive industry [1]. 3D printing is an effective design tool due to the ability to perform several stages of structure production in a short period of time . Today, 3D technology can be used to create functional prototypes using high-performance materials such as ULTEM and PEEK. This technology is actively used by 3DGence .

The benefits of the technology for automakers are that it overcomes product design limitations, shortens product development time, and reduces research costs with synchronous development to improve the reliability of new products.
UnionTech 3D printers are widely used in the automotive industry. With their help, you can quickly evaluate the design of the model and check the part for assembly.

They represent a significant part of the total costs for many car manufacturers and suppliers. Mass production of spare parts is common in traditional manufacturing . However, this often leads to long lead times and high parts costs[4].
Additive manufacturing is changing the concept. Spare parts are produced on site when needed. Thus, coordinating supply and demand can not only significantly reduce inventory costs, but also shorten delivery times to the final consumer.
The German car manufacturer Porsche uses additive technologies in the production of spare parts. For Porsche collectors, the Classic has high value. However, due to the lack of the required part, the machine cannot run. But because of the low demand for these machines, it is not profitable to buy spare parts for them in bulk. This is where 3D printing comes in.
At the beginning of 2018, the company announced the use of 3D printing in the production of parts for rare and classic cars. By introducing selective laser melting (SLM) for metal components and selective laser sintering for plastics, Porsche offered its customers a wide range of high-quality unique parts at affordable prices.
One of the main barriers to using 3D technologies in manufacturing is the high volumes (more than 100,000 parts per year) typically required by the automotive industry. Today, however, industrial printers are larger, print speeds are faster, and print media are more affordable.
As a result, 3D printing is becoming the main method for certain mass production. We are talking about areas such as motorsport and luxury cars, where production figures are below average.
With more than 1 million 3D-printed parts over the past decade, BMW is well positioned in the additive manufacturing industry. The company used 3D printing to produce metal parts for its i8 Roadster model. Engineers have created an optimized roof bracket ( a device that helps fold and unfold the soft top of the car ) that weighs 44% less than previous versions [2-3].
Today, BMW can print up to 238 of these parts per platform, making the roof rack the first mass-produced additive manufacturing automotive component.
