For example, new technologies – in line with the Gartner Hype Cycle – usually pass through five stages of public attention. A technological trigger seizes people’s imagination, and generates exaggerated expectations, which rapidly give way to disillusionment. Only then will realistic assessments come to the fore, enabling the technology concerned to be productively used.
A productive plateau of this kind has been achieved in the 30-year history of technology by rapid prototyping, for example, by layer-by-layer construction of single pieces and sample components from CAD data, and by 3D printing of hearing aids. Applications in the fields of dental technology and automaking have left the disillusionment phase behind and have long since been evolving into successful models. Other processes like 3D printing of consumable materials, surgical implants or bioprinting of human tissue still have a long way to go.
What business models for additive manufacturing might look like is exemplified by Protiq GmbH, a subsidiary of Phoenix Contact GmbH & Co. KG and represented at Inside 3D Printing by Johannes Lohn. Industrial customers upload the data of their 3D models to Protiq’s website, select the material they want, and place a printing order. The models will then be printed within a few days, and dispatched worldwide. “The quality is in some processes so high that intensive reworking is not needed. It suffices to polish the workpieces at certain points, and they can be used directly,” emphasises Stefan de Groot, Additive Manufacturing Technologist at the METAV’s Press Forum in Blomberg. He sees the advantages in significant cost reductions, particularly for small batch sizes, but also in greater functional depth. Close-to-contour cooling and weight reductions based on topological optimisation, for example, are reflected in simpler handling.
“As an international meet-up for the sector, Inside 3D Printing provides an opportunity to talk with top-ranking speakers and companies,” explains Prof. Dr.-Ing. Franz-Josef Villmer from Ostwestfalen-Lippe University, who will be acting as the host for this conference. “In the shape of Dr. Phil Reeves and Prof. Thierry Rayna, for example, we have brought on board true pioneers and visionaries of additive manufacturing, whose keynotes are definitely something for visitors to look forward to. That their introductory thoughts will be followed by consistently excellent panels and specialist sessions is not something we should take for granted, and makes us just a little bit proud.”
Visitors to the METAV will thus perceive Inside 3D Printing as an ideal supplement to the fair’s other attractions. While at the exhibitors’ stands they will experience the latest state of the art, the conference at the fair will provide them with insights into what companies have in the pipeline for the future. But trade visitors who travel to Düsseldorf only for the Inside 3D Printing event will also find it definitely worthwhile. To quote Prof. Villmer: “Because we are moving away from frontal lectures and giving preference to meaningful interaction between speakers and conferees, a visit is well worthwhile for all stakeholders in 3D printing. They will meet experts with huge funds of specialised knowledge, able to provide a crucial boost for their own work. This creates a genuine added value.”
