3D printing, a technology of the future: the future began a long time ago in Bavaria

When it comes to cross-industry innovation, 3D printing plays a crucial part. Additive manufacturing can save materials and time and it’s possible to produce more precise components that are stronger. Thanks to networking the process chain using the Industry 4.0 approach, it also manages to manufacture customised elements in small numbers as required.

More and more materials can already be printed today and in ever faster and better quality. While 3D printing once began with plastics, the use of metals has also been successful for a long time. Whether it’s turbine blades, hip joints, soles of shoes or spare parts, additive manufacturing processes are present in all application areas and industries today. As a result, more and more products from 3D printing are being used in mechanical engineering, the aerospace industry and medical technology today.

What is 3D printing?


In contrast to traditional manufacturing process where a material is worn down by turning, milling or boring, 3D printing is a generative process. A workpiece is built up layer by payer by adding materials, which is why it is called additive manufacturing. While at the start it was mainly about the simple manufacturing of prototypes, it has long succeeded in making the jump to be a recognised manufacturing method. The following advantages smoothed the way for the process:

  • Production in no time at all
  • More complex geometries possible compared to classic manufacturing (milling, welding)
  • Less material consumption
  • Considerably lighter weights for components
  • Functional integration of lines

Promoting technology in Bavaria


The potential of this technology was recognised in Bavaria a long time ago. Which is why the state is placing great importance on promoting research and development projects in the field of “Additive Manufacturing / 3D Printing” as part of the Bayern Digital II master plan and the Bavarian ”New Materials” research programme. Research is mainly to be conducted into collaborations between companies, involving research institutes as necessary. There are currently research projects, for example, at the Universities of Würzburg, Erlangen-Nuremberg and Bayreuth where there is even a newly created Master’s course in “Biofabrication”. In addition, the first BayernLab was also opened in Traunstein in 2016 where anyone interested can test 3D printers themselves.

 

Leading providers in Bavaria


Concept Laser
Concept Laser GmbH, founded in Lichtenfels, Upper Franconia in 2000, is one of the leading providers of 3D printing for metal components for mechanical and plant engineering. Since December 2016, Concept Laser has been part of GE Additive, a division of the global industrial company General Electric. At least EUR 100 million is going to be invested and 500 new jobs are going to be created at the company head office in Lichtenfels.

Application areas and industries

 

  • Fuel systems, moving and stationary blades, heat protection components, drive and turbine parts, rocket elements and high-quality components for the cabin and cockpit equipment, among other things, are made using 3D printing processes in the aerospace industry.
  • Car manufacturers and suppliers use additive manufacturers, for example, for engine components, bodywork and structural parts and direct components for interiors. It is also suitable for direct components in pre-series development and small parts production.
  • Medical technology is building manufacturer-specific modifications with small batch sizes and customised implants up to batch size 1 on 3D printing. But also with the series production of standard implants.
  • A variety of dental products like crowns, caps, model casts and secondary constructions, such as mouth guards are being produced in the dental industry.
  • 3D printing is being used for customised pieces of jewellery, one-offs, small series or display models in watch and jewellery making.
  • There are various applications in tool and mould making, e.g. measuring devices, injection moulding, stapling devices and clamping fixtures for production, cooling channels, etc.


Besides the leading players in 3D printing in Lichtenfels and Munich, a cluster for additive manufacturing has mainly developed in the greater area of Augsburg. Several hidden champions are active in Swabia and sell their highly specialised products worldwide. The Experience Additive Manufacturing multi-location event also took place in Augsburg for the first time this year. Thanks to the involvement of locally based companies and research, a new trade fair concept was developed where accompanying events are also held, for example, in cooperation with the Fraunhofer Institute.
