SondaSYS is a company founded by experts and practitioners in the fields of 3D printing, prototyping, and CAD / CAM construction. We have 15 years of experience in the 3D printing industry and we had been one of the first in Poland operating in this field. Over the years, we have been distributing and servicing 3D printers in many technologies: FDM, SLA, SLS, 3SP, DLP, and Polyjet. We have built our experience and knowledge based on cooperation with numerous research centers and technology parks, including: – AGH University of Science and Technology in Kraków; – Rzeszow University of Technology; – The Silesian Technical University; – University of Silesia; Thanks to the knowledge and experience gained over the years, we have created an interdisciplinary team that was guided by one thought: to create a professional SLS 3D printer that will be both reliable and intuitive to use, economical, and optimized for market needs. Thanks to cooperation with many scientists from around the world (including Poland, China, France, Great Britain) we have managed to create an industrial SLS device and optimize it in areas, where nobody has done so far, in ex. equip SLS 3D printer in the option of changing build volume/ build chamber size.
