We are looking for ambitious and hardworking graduated students for Master/PhD projects aimed to help

Directions of our current researches include but not restricted to :

1. Our approach by laser powder bed fusion (LPBF) fabrication of 3D parts from metal matrix composites (MMC) we implemented based on nickel-chrome heat resistant alloy with WC ceramic reinforcing additives. The possibility of functional graded structures (FGS) from these MMC for the account of increasing the alloying element concentration from 5% to 15%vol of the tungsten carbide in NiCrSiB self-fluxing alloy was shown. We strongly recommend additional heating of the initially powdered mixture and/or substrate for temperature gradient reduction in the volume of the 3D part, homogenization of structure and decreasing residual stresses and propensity to delamination. // Shishkovsky et al (2019). Layerwise fabrication refractory NiCrSiB composite with gradient grow of tungsten carbide additives by selective laser melting. Optics and Laser Technology, 120, 105723. doi: 10.1016/j.optlastec.2019.105723 (IF=4.94; Q1)

2. The effect of laser thermocycling and tempering on structural heterogeneity and electro-structural properties of 2D layers and 3D multilayers of nickel-titanium intermetallide during the laser powder bed fusion (LPBF) process has been studied. Necessity of the laser melting and solidification parameters tuning, implementation of preliminary and subsequent laser tempering was proved by the final state of the shape memory alloy (SMA). It is shown that specific electrical resistivity of the studied phases (austenite, R-phase, martensite) abnormally varies with temperature. Varying structural heterogeneity by changing the laser influence parameters and/or heat treatment allows us to get a material with different functional properties. It can be used both in medicine for approximating SMA to the human body temperature, and also in high-temperature applications, as dampers. // Shishkovsky et al (2020). Influence of laser cycling on electro-structural features of nickel-titanium SMA fabricated by LPBF process. // Applied Surface Science, 508, 145278. doi: 10.1016/j.apsusc.2020.145278 (IF=7.39; Q1)

3. Metamaterials are able to demonstrate extremely high rigidity in one direction and extremely high compliance in other directions. Pentamode metamaterials can, therefore, be considered as building blocks of exotic objects with any arbitrarily selected thermodynamically admissible elasticity tensor. In this study, several anisotropic individual and hybrid pentamode lattice structures were produced by the Multi Jet AM, mechanically tested under compression and compared with Comsol FEM simulation. It is concluded that the elastic E, shear G, and bulk moduli B of the hybrid structure are the superposition of the corresponding moduli of the individual lattice structures. Poisson’s ratio ν of the hybrid pentamode structure equals that of individual structure with higher Poisson’s ratio. The yield stress σy of the hybrid pentamode lattice structure depends on the elastic moduli of the constructing lattice structures, as well as the yield stress of the weaker lattice structure. // Mohammadi et al (2020). Hybrid anisotropic pentamode mechanical metamaterial produced by additive manufacturing technique. // Applied Physics Letters, 117, 061901; doi: 10.1063/5.0014167 (IF=3.97; Q1)

4. This is a first review, which discusses the development prospects of additive technologies for the manufacturing of complex technological items on the surface of the Moon under scarce resource availability and low-gravity conditions. One of the expected materials for 3D printing as part of a prospective lunar research program is the lunar regolith. It is easily accessible on the Moon in a few forms, depending on geographical location. Due to the limited availability of the lunar regolith on Earth, several attempts to use geological simulants of the regolith were made by research groups worldwide to analyze the applicability of additive manufacturing (AM) technologies for lunar 3D printing. All available experiments with 3D printing for in-situ fabrication with lunar regolith were analyzed, systematized, and generalized. Finally, the basic requirements and approaches for adapting additive manufacturing methods to lunar surface conditions were formulated. // Isachenkov et al (2021). Regolith-based Additive Manufacturing for Sustainable Development of Lunar Infrastructure – an Overview.  Acta Astronautica, 180, 650-678. Doi: 10.1016/j.actaastro.2021.01.005 (IF=2.95; Q1)

5. Piezoceramic materials provide the foundation for essential components of modern engineering applications in the fields of acoustics, sensorics, biomedical devices, and microelectronics. With device miniaturization, the industrial requirements for piezoceramics with complex geometries and improved efficiencies has grown tremendously. Additive manufacturing (AM) technologies applied to traditional piezoelectric materials has many obstacles to overcome, since typical piezoceramic products require complex and intricate shapes, and often consist of composite materials. This review intends to outline the current state of the art of AM technologies applied to the manufacture of piezoceramic materials. The properties of piezoceramics and their composites are compared for traditionally and additively manufactured devices. The pros and cons of AM technologies are discussed, and the problems to be addressed in our following studies work are highlighted. // Smirnov et al (2021). Progress and challenges of 3D-printing technologies in the manufacturing of piezoceramics.  Ceramics International, 47(8), 10478–10511. Doi: 10.1016/j.ceramint.2020.12.243 (IF=5.53; Q1)

6. Lunar regolith is the most critical material for the in-situ resource utilization (ISRU) in the crewed Moon exploration missions. This natural material can be utilized for the additive manufacturing of concrete or ceramic parts on the Moon’s surface to support permanent human presence on the surface of Earth’s natural satellite. The present study describes the characterization of the LHS-1 and LMS-1 simulants using XRF, XRD, SEM, EDX, DTA, TGA, UV/Vis/NIR spectroscopy, and laser diffractometry methods to provide data on their mineral, chemical, and fractional composition, as well as, on their morphology and optical properties. It was found that LHS-1 and LMS-1 simulants well mimic the primary properties of the original lunar regolith and can be potentially used for ISRU research tasks. // Isachenkov et al (2022). Characterization of novel lunar highland and mare simulants for ISRU research applications.  Icarus, 376, 114873. Doi: 10.1016/j.icarus.2021.114873 (IF=3.66; Q1)

7. Potential application of the additive manufactured (AM) parts is still inhibited by poor fatigue properties. In this work, we applied laser polishing to simultaneously reduce factors that affected the fatigue properties, such as surface roughness and sub-surface porosity. Our findings show that significant porosity reduction in sub-surface area can be achieved with one scan pass without major deterioration of surface quality. The surface quality, sub-surface layer porosity and mechanical properties of the laser polished with pore removing pass and conventionally laser polished samples are compared with as-built samples. // Panov et al (2022). Pore healing effect of laser polishing and its influence on fatigue properties of selective laser melted SS316L parts.  Optics and Laser Technology, 156, 108535. doi: 10.1016/j.optlastec.2022.108535 (IF=4.94; Q1)

8. Additive manufacturing (AM) with lunar regolith is a promising in-situ fabrication and repair (ISFR) method that can be used for sustainable local production of engineering tools and components. The evolution of properties of highland and mare lunar regolith simulants concerning grinding-based pre-processing was studied in this work, relevant to stereolithography-based AM. Particle size distribution, mean particle size, UV–Vis, XRD and XRF spectra were acquainted from the samples, ground in a ball mill at various grinding times (to different fraction sizes). The photopolymerization efficiency was assessed for lunar simulant-infilled resins prepared from lunar regolith simulants ground with different parameters. It was found that the grinding time of lunar regolith simulants strongly influences their optical properties – the light absorption in the far UV increased by 5.5 times. Based on the measured photo-polymerization depth, the optimal grinding procedure for mare and highland lunar regolith simulants was determined. // Isachenkov et al (2022). The effect of particle size of highland and lunar regolith simulants on their printability in vat polymerisation additive manufacturing. Ceramics International, 48(23), 34713-19. doi: 10.1016/j.ceramint.2022.08.060 (IF=5.53; Q1)

9. The direct energy deposition approach implements a unique opportunity for controlling the fabrication of functionally graded (FG) and sandwich structures from different metal powders for artificial physical properties management. Our study revealed the promising FGS into Fe-Cu system based of SS316L with bronze and for the first time prediction of mechanical properties in those sandwich systems. // Makarenko et al (2022). Mechanical characteristics of laser-deposited sandwich structures and quasi-homogeneous alloys of Fe-Cu system. Materials and Design, 224, 111313. Doi: 10.1016/j.matdes.2022.111313. (IF=9.42; Q1)

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 creating products with a new level of performance and shapes. Moreover, this technique allows to the production of prototypes rapidly and leads to reducing costs and risks. Another crucial advantage of the technology is the unprecedented design flexibility that lets us create 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.

Course MA03354 – 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 scaffold-based TE approaches. A big part of the course will be devoted to the main processes of 3D bio-fabrication. We will describe the key stages in 3D bioprinting, which are the material choice (bio-materials 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 bio-printing, 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.
