Why 3D Print Car Prototypes?
Producing prototypes was one of the first applications of 3D printing technology and the automotive industry pioneered this development. 3D Printing allows businesses to produce parts faster than with conventional methods. Today, the technology is cost-efficient and offers highly accurate parts and a wide range of high-quality finishing options, leading to an incredible resemblance to reality.
The benefits are obvious. How about the challenges? Tata Motors, Engineering Research Centre-Prototype Manufacturing (ERC), experienced that a large part of their prototype volume was caused by support structures. Finding the optimal configuration for the supports required trial runs. In addition, insufficient data preparation led to build failures. Fortunately, our 3D printing software suite could help them to fix these issues.

The Benefits of Smart Software
Tata Motors ERC currently uses Materialise Magics for their data preparation. They use it to convert CAD files to STL, fix all errors and cut, merge, hollow, label, and rescale parts – and much more. For their Laser Sintering production, they use the Magics Sinter module to automatically nest all parts at the nesting density and height of their choice. This software module speeds up data preparation, reduces powder consumption and offers many ways to control the Laser Sintering process.
For their Stereolithography production, ERC uses Materialise e-Stage, a software program which automatically generates support structures. This automation wipes out human errors and only places support where it is indispensable. The toothed connection points make support removal a lot easier, resulting in a higher surface quality. In case texturing is needed, Materialise 3-matic software helps to create aesthetic and functional textures, patterns and perforations.

Smooth 3D Printing Operations
“Materialise Magics, which is a part of the Materialise Magics 3D Print Suite, is very helpful software in that it provides advanced STL repair tools for fixing our files. It also gives us more confidence to 3D print parts without any defects or deviations, leading to innovative, high-quality products for our customers.”
- Yeole Hemkant, Senior Manager – ERC Prototype Manufacturing, Tata Motors
Backed by Materialise software, Tata Motors ERC-Prototype Manufacturing, now produces 3D-printed prototypes that consume less material and are of higher quality. The support structures occupy around 30% of a part’s weight, whereas they weighed double or even triple before. Their data preparation process is sped up and generates less build failures.
