The main goal of our research is to find prospective powder compositions for the fabrication of functional parts by the SLS/M and 3D laser cladding processes (DMD, LENS), and to study their properties and synthesis conditions. The results are expected to be utilized in medicine (orthopedic implants), the oil, gas, and chemistry industries (filter elements, catalytic membranes), in electrical engineering (piezo elements) and in auto, aerospace and other branches of precision engineering. In other words, the applications encompass any industry where there are problems of modeling and RP&M, which utilize powdered materials. The list includes: a) shapes cast from a sintered master pattern; b) functional customized parts and tools with unique physical characteristics.

The current studies at Prof. Shishkovsky group are directing on the combinatory approach had been realized for the first time into our researches on graded metal matrix composites (MMC) based on titanium, nickel and/or cobalt matrix, with the layerwise increasing content of Al₂O₃, TiC, TiB₂, WC nanoceramics. In certain cases, we recommend additional thermal heating of the initial mix and/or substrate for temperature gradient reduction in the volume of the 3D part to decrease residual stresses and propensity to delamination. Developed us a combinatory method is an effective tool for detection and design of new alloys for additive manufacturing (AM), studying of phase-structural transformations in non-equilibrium conditions of 3D laser synthesis, and prediction of other perspective MMC and heat resisting alloys (Genome of Material for Combinatorial Design and Prototyping of Alloys ) for aircraft & nuclear industries.

Course MA06243 – Fundamentals of Additive Technologies

Additive manufacturing (AM), also called 3D printing, has become an extremely promising technology nowadays. Unlike traditional manufacturing processes such as welding, milling and melting that involve multi-stage processing and treatments, AM allows to create products with the new level of performance and shapes. Moreover, this technique allows to produce prototypes rapidly and leads to reducing costs and risks. Another crucial advantage of the technology is the unprecedented design flexibility that let us create the samples of high quality based on different materials such as metals, alloys, ceramics, polymers, composite materials etc.

The main goal of this course is to represent the fundamental basis of different additive technologies to the students. In this course, a wide range of questions will be addressed, beginning from the process of chain and designing the structures up to various 3D printing technologies, materials and process parameters, benefits and drawbacks of AM approaches will be considered. During laboratory class, we will get acquainted with the additive technologies on various printing machines. Students will be able to create their own models, print them in metals, ceramics and polymers, and also analyze the properties of the final samples. During this course, a complete cycle of production of samples using various 3D printing techniques will be explored both theoretically and practically.

Planning Course – 3D Bioprinting: Processes, Materials and Applications

Additive manufacturing technology offers significant advantages for biomedical devices and tissue engineering due to its ability to manufacture low-volume or one-of-a-kind parts on-demand based on patient-specific needs, at no additional cost for different designs that can vary from patient to patient, while also offering flexibility in the starting materials.

The course starts with the introduction of tissue engineering (TE) and the scaffold-based TE approaches. A big part of course will be devoted to the main processes of 3D biofabrication. We will describe the key stages in 3D bioprinting, which are the material choice (biomaterials and cell source), pre-processing (CAD and topological optimization), processing (the 3D bioprinting systems and processes) and post-processing (cell culture). The application areas of bioprinting, including tissue engineering and regenerative medicine, clinics and transplantation, pharmaceutics, and the future trends in bioprinting that will revolutionize the organ transplantation technology in the next decades will be discussed.
