Scientific Tutorials (Wednesday)
Cora Lüders-Theuerkauf (Germany): Introduction into Medical 3D Printing - Promises and Limitations
Tutorial 1: Introduction into Medical 3D Printing - Promises and Limitations
Dr. Cora Lüders-Theuerkauf, Mobility goes Additive e.V. (MGA)
Additive manufacturing (AM) has long been established in many industrial sectors. One particularly exciting field is medicine / medical technology. AM enables the production of patient-specific, individual implants, prostheses, orthoses, tissues, precision tools and much more. A variety of different technologies and materials are used to provide the best possible patient care. Regulatory requirements are high, but quality management is improving, especially in hospitals with point of care manufacturing. This presentation will give an overview of the many various use cases and show the latest developments with respect to needs, materials and manufacturing processes. AM is not only an important component in personalized medicine, but also helps to reduce costs and risks.
Lecturer

Dr. Cora Lüders-Theuerkauf studied biology in Göttingen, Hannover and Boston and holds a PhD in natural sciences. She has extensive experience in project management and coordination of research projects during her almost 20-year career in clinical research in the field of tissue engineering. Since 2013 she focused on 3D printing in medicine. In 2019 Cora established MGA Medical and is the network manager of this unit within the Network Mobility goes Additive e.V. (MGA) where she manages currently six medical working groups and is responsible for the development and representation of the MGA Medical division. With her outgoing nature she pushes AM topics in medicine.

Marc Wachenhausen & Thorsten Haslinde (Germany): IP Protection in Medical 3D Printing
Tutorial 3: IP Protection in Medical 3D Printing
Marc Wachenhausen & Thorsten Haslinde, WBH Wachenhausen Patentanwälte PartG mbB, München, Germany
Patents are exclusive rights that can only be granted for technologies that are new, inventive and industrially applicable. Patents are assets which can help attract investment, secure licensing deals and provide market exclusivity. A patent can be maintained for a maximum of twenty years. Additive manufacturing (AM) patent applications at the European Patent Office (EPO) grew on average at a two-digit rate in the last years, much faster than the average yearly growth of patent applications at the EPO in the same period. A large share of the AM patent applications is directed to inventions in the medical and health sectors. Due to the nature of many AM inventions, there is a risk that traditional patent protection strategies do not ensure a thorough and enforceable protection of the AM invention. Recent landmark decisions of different Patent Offices and Patent Courts have acknowledged the new nature of AM inventions and provide new opportunities for effective protection of AM inventions through patents.

Scientific Keynotes (Thursday / Friday)
Olena Sych (Ukraine): Advancing Regenerative Medicine: Biogenic Hydroxyapatite and Glass Ceramics Based on it for Medical 3D Printing
Keynote: Advancing Regenerative Medicine: Biogenic Hydroxyapatite and Glass Ceramics Based on it for Medical 3D Printing
Dr. Olena Sych, Head of Department of Functional Materials for Medical Application, Frantsevich Institute for Problems of Materials Science, National Academy of Sciences, Ukraine
Hydroxyapatite (synthetic and biogenic) and based materials are widely used for treating bone fractures in orthopedics, traumatology, and dentistry due to their exceptional in properties and similarity in chemical composition to the mineral component of natural bone. Biogenic hydroxyapatite has higher bioactivity than synthetic hydroxyapatite due to its native chemical composition and porosity. Moreover, it can be efficiently and cost-effectively produced from natural sources. Biogenic hydroxyapatite from cattle bones and glass ceramics based on it created in Frantsevich Institute for Problems of Materials Science of NAS of Ukraine have been successfully used in practice by leading Ukrainian surgeons in the form of powder, granules, blocks, porous and dense ceramics, and bioadditives in orthopedics, traumatology, purulent-bone surgery, dentistry, for bone tissue in plastic surgery, and treatment of osteoporosis.
Currently, the structure and properties of biogenic hydroxyapatite and glass ceramics have been modified by microwave sintering, foam replication method, and different additives like silicon, copper, iron, magnetite, etc. That allows for changing mechanical properties and resorption rate. However, using traditional methods of producing bioceramic implants requires additional technological operations to obtain specimens of the required shape and size. Additive manufacturing technology will allow the production of customized implants for each patient. Biogenic hydroxyapatite and glass ceramics based on it can be promising and low-cost materials for medical applications of 3D printing.

Dr. Olena Sych is Head of Department of Functional Materials for Medical Application at Frantsevich Institute for Problems of Materials Science (IPMS) of the National Academy of Sciences of Ukraine and researcher at Laboratory of Nanostructures of Institute of High Pressure Physics of the Polish Academy of Sciences. She is PhD in Materials Science. She teaches lectures for post-graduate students in IPMS about bioceramics and biomaterials. Her research work connected with creation and investigation of materials for bone tissue engineering based on hydroxyapatite. She is the leader of 15 grants and projects as well as the author of 140 scientific publications, including 3 patents. She believes that scientific work is impossible without interdisciplinary cooperation.
Anton du Plessis (South Africa): X-ray Computed Tomography for Additive Manufacturing: Improved Non-Destructive Evaluation Using Deep Learning
Keynote: X-ray Computed Tomography for Additive Manufacturing: Improved Non-Destructive Evaluation Using Deep Learning
Prof. Dr. Anton du Plessis, Object Research Systems, South Africa / Montreal
X-ray computed tomography is a popular non-destructive evaluation method for additive manufacturing, to provide confidence in part quality and to quantify the defects in critical parts, for example to ensure they are smaller than some size limit or less than some maximum volume fraction, or below the detection limit in critical areas. The method is key to process optimization, quality control and is undisputed as one of the best tools for evaluating AM parts.
In recent times, deep learning methods have become popular in various fields, and in the context of CT for additive manufacturing, there are some advancements that are highly valuable for this application. In this talk, two methods are discussed in some detail. The first is image enhancement using deep learning. This can be achieved by different methods, one of which is called “super-resolution”. In this approach, a poor resolution and high resolution scan of the same object is used to train a model to improve the quality of poor resolution scans of similar parts. This allows enhanced contrast on poor resolution scans, which allows the user to save time in scanning or scan at larger voxel size while getting more reliable results similar to a high resolution or longer scan time. This will be demonstrated using a lattice structure sample, which is often used in AM medical implants, but often cannot be scanned at high resolution due to size limitations on the object size vs the lattice feature size.
A second method involves teaching a deep learning model to segment AM porosity. The challenge with AM pores are that they are small and often near the voxel size of the scan, making their contrast insufficient for a good manual segmentation. There is also often a challenge with image artifacts due to material density or scan quality issues. These issues make the quantification of porosity challenging, especially when high throughput is required. Deep learning segmentation models can be developed to perform this task despite poor contrast and despite image artifacts, providing superior results in comparison to traditional “thresholding” methods. Results will be demonstrated on using such a model “out of the box” as a pre-trained model, as well as using this model as a starting point for adding training to make a stronger model.
Overall these techniques can assist in improving the use of CT for AM in terms of reliability and ease of use, and has great potential for automation of the image analysis workflows involved in using CT (since deep learning models, once trained, do not require any human input).
