Samara Polytech has developed original filaments
Today, polymeric filaments (filaments or rods for printing on 3D printers) are widespread and available. Wax patterns, on the other hand, are still very expensive, with only a few companies in the world producing them. Anton Barinov, a leading engineer of the Centre for Foundry Technology of Samara Polytech, together with Ivan Ermakov, who was still a master's student at the time, decided to develop the author's filaments.
There are now four rolls of wax filaments (one type of filament was even made from recycled wax) in the additive technology laboratory, with different melting temperatures. Over the past two months of observation, there have been no visible irregularities. During tests now under the supervision of Konstantin Nikitin, dean of the Faculty of Mechanical Engineering, Metallurgy and Transport of Samara Polytech, scientists plan to confirm the required technological properties of this material (low shrinkage, low coefficient of thermal linear expansion, dropping point within 89-97 °C). As a result, a wax filament of Politech own production will be competitive in price and quality.
Special equipment for filament development was supplied by Polymet, an industrial partner of Samara Polytech. The company also provided a number of raw materials for the experiments.
By the way, not so long ago scientists of the Faculty of Engineering and Technology of Samara Polytech created thermoplastic materials in the form of filaments for 3D-printing. However, the chemists-technologists expect to find applications for them in the field of geophysics.
