The aerospace industry is characterized by small quantities, the highest safety requirements and, more than almost any other industry, by the need to save weight. Every reduced kilogram of weight saves up to 3 kg of CO2 - and that on a daily basis. Moreover, the short-term supply of spare parts is quite challenging. That is why aerospace industry is ideal for the introduction of components that are topologically optimized and manufactured by 3D printing processes. For more than 10 years, parts have been converted from conventional design and manufacturing to additive processes. The results are clear: components become lighter, smaller and may even integrate more functions.

Nevertheless, the conversion process is progressing slowly. There are several reasons, starting first and foremost with the demand for maximum safety. With existing design and production processes, all necessary qualifications are available for the required safety of components. For 3D printing, unfortunately, we are still at the beginning and, therefore, invest a lot of time and energy in process qualifications. We have to ensure that the internal structures and the surfaces meet all the requirements for permanent, safe operations. In parallel, we are, of course, continuing to work on optimizing the processes, on new material combinations and design processes, because we are certain that 3D printing will be indispensable for the climate-neutral aircraft of the future.

 The EU Medical Device Regulation MDR effects manifoldly additively manufactured products in medical applications. Substantially, most generally applying MDR requirements are clear and unequivocal and for manufacturers of custom-made products and health institutions are allowed to follow special procedures. And yet, especially when looking at the entire production chain of patient-specific medical products, new uncertainties have arisen, which required clarification work, which in some cases is still on-going.

Over the years, the so-called Medical Device Coordination Group (MDCG) has developed publicly available supporting guidance documents for many MDR topics. For additively manufactured medical devices, the MDCG document 2021-3 “Questions and Answers for Custom-Made Products” was published in March 2021, shortly before the MDR came into force, and the MDR legislation was passed at national level.

This presentation gives an overview of these current developments using practical examples and points out the risks and opportunities that have emerged with the new regulations.

3D printing in medicine is experiencing stable growth even in pandemic times. Irrespective of the crisis, the industrial production of implants and instruments is being continuously optimized. Thanks to industrial FDM technology, the additive manufacturing of patient-specific polymer cranial implants has a disruptive character, as investment and material costs can be significantly reduced compared to conventional manufacturing techniques and alternative materials. Individualized polymer cranial plates today are predominantly made of PEEK, a high-performance polymer that is widely used and accepted in medical manufacturing. Currently, the implants are mostly milled. This means low resource efficiency, as only 10% or less of the processed material is used for the implant. In addition, the investment in hardware and maintenance is much higher compared to an industrial FDM printer. Here, the waste of an implant is around 10% of its own weight, primarily due to the support structures that are necessary in FDM printing.In addition to PEEK as an established material for cranial implants, titanium implants are also manufactured additively.  Again, significantly higher investment costs and maintenance costs for the printer contrast with the comparatively low investment in an industrial FDM printer.  In summary, industrial FDM printing of implants is an economically attractive solution for MedTech companies compared to titanium printing or polymer milling.

Practical experiences show possibilities, limits and an exemplary learning curve in dealing with additive manufacturing. On the basis of concrete application examples, solutions are presented whose implementation without 3D printing would be very difficult or impossible.
Introduction

Digital manufacturing has been finding its way into OT for some time now and will manifest itself even more strongly. Besides the daily process acceleration, which is aspired in many places, the innovation potential is a decisive factor to adopt this technology and to increase the quality of supply.
Methodology
Due to the lack of specifications and characteristic values in always individual areas of application, the procedure is strongly determined by personal experience, trial and error as well as test series. Wall thicknesses, surface structures, material selection as well as printing processes offer a multitude of factors which seem to increase the possibilities of application. New technologies, surface structures as well as finishing techniques have therefore always been used in consultation with patients, in consultation with manufacturers and service providers. Current developments in manufacturing technology as well as a lively exchange with technicians as well as manufacturers and producers is a way to success in correctly assessing the potentials.
Conclusion
The use of printed aids goes far beyond cosmetic coverings and mere process optimisation. First and foremost, orthopaedic technicians are given the opportunity to define new fitting standards and to integrate new functions with the help of manufacturing precision that was previously difficult to achieve. In this way, the quality of the aids can be increased not only functionally but also aesthetically.

The Presentation highlights opportunities and challenges of incorporating AM technology on the Boeing 777X Folding Wingtip System Secondary Lock Actuator.

The Case Study shows how Liebherr addressed challenges like thermal stresses in production, pressure drops in operation, surface treatment and wear surfaces of titanium cylinders.
Furthermore, an outlook will be provided regarding the challenges of the technology and the implementation to serial production of highly integrated components.
