Anton Barinov, a leading engineer of the foundry Technology Center of Samara State Technical University, a member of the world-class scientific and educational center "Engineering of the Future", together with Ivan Ermakov, who was still a master's student at that time, decided to develop author's filaments.
Now in the laboratory of additive technologies there are four coils of wax filaments (one type of thread was made even from recycled wax), differing in melting point. Over the last two months of observations, there are no visible violations. During the tests currently being conducted, scientists plan to confirm the required technological properties of this material (low shrinkage, low coefficient of thermal linear expansion, drop-off temperature in the range of 89-97 ° C). As a result, a wax filament of our own polytechnic production, competitive in price and quality, will be obtained.
By the way, not so long ago scientists of the Faculty of Engineering and Technology of Samara Polytechnic University created thermoplastic materials in the form of threads for 3D printing. However, the chemists and technologists of the Polytechnic expect to find application for them in the field of geophysics.
By the way, in July of this year, the Russian government approved a strategy for the development of additive technologies for the period up to 2030. It is expected that this will increase the volume of the Russian market of additive technologies by more than three times and will become an additional incentive for the innovative development of the domestic economy.
