Equipment imported from the United States will meet the demands of several Centre projects; companies may contract the service<\/em><\/strong><\/p>\n

The FAPESP Shell Research Centre for Gas Innovation (RCGI) began the purchase process of a 3D printer for metal parts that will serve the demands of several projects of the Research Centre headquartered at the University of S\u00e3o Paulo (USP). About two months after the equipment acquisition is finalized, which is imported from the United States, it is expected to arrive in S\u00e3o Paulo.<\/p>\n

\u201cThe advantage of this printer is that it can manufacture parts, directly in metal, that have complex formats, that is, things that cannot be made with conventional manufacturing methods,\u201d states mechanical engineer Em\u00edlio Carlos Nelli Silva, Professor in USP\u2019s Polytechnic School and Director of the RCGI\u2019s Engineering Program. \u201cWe\u2019re talking about parts that have many curves and have specific finishing specifications; there are no geometric limitations,\u201d he says, and cites, as an example, the projects that attempt to develop labyrinth sealing joints, to avoid leaking of gases such as methane, in pipes, and supersonic separators, which are devices in tubular formats that aid in separating CO2<\/sub> and CH4<\/sub> gases.<\/p>\n

Besides serving the RCGI\u2019s researchers and professors and the academic community, the device \u2013 called Studio System\u2122, developed and produced by U.S. company Desktop Metal \u2013 will become a part of a multi-user laboratory in the research center. \u201cWith this philosophy, the equipment can be rented, that is, contracted, by companies at market prices; with this income, we hope to keep up the maintenance of the printer,\u201d Silva states.<\/p>\n

According to the Director of the RCGI\u2019s Engineering Program, the idea of the Centre acquiring a 3D metal printer, like this one, dates back to 2015, when the RCGI was founded, but it is materializing only now, after dealing with economic issues and the bureaucratic phases for acquiring high-priced equipment. \u201cThis process has gone back and forth, with the ups and downs of the dollar and all the rest, and finally came together.\u201d<\/p>\n

Consisting of basically three pieces of equipment \u2013 the printer itself, a tank for chemically processing the parts (debinder), and an oven producing temperatures as high as 1,400 degrees Celsius \u2013 the system, according to the researchers, is relatively compact (it requires a 50 square-meter space in the laboratory) and is lightweight, facilitating the installation and moving of the machines in a research laboratory. \u201cWith this technology, you don\u2019t need much space. It is even smaller than another printer we have here using polymers,\u201d states Francisco Oliveira, researcher of the Multiphysical Systems Optimization Laboratory (MSOL) of Poli-USP.<\/p>\n

Silva says that another advantage of the system is that the printer uses cartridges with solid bound metal rods mixed with polymers, thus avoiding the risks of working with powdered metal in the lab. The produced parts can have a maximum size of 15 centimeters (cm) high, by 25 cm wide, and 15 cm deep. Furthermore, a prototype can be readied within one to three days, whereas a complex part made from a mold can take weeks or months to be ready via the conventional method.<\/p>\n

To the present time, the RCGI\u2019s researchers on projects, such as labyrinth sealing joints, used polymer printers. \u201cThe metal printer shows how feasible it is to make a metal part,\u201d Silva says.<\/p>\n

\u201cThis equipment will assist with the RCGI\u2019s and the University\u2019s internal projects and it also fits into the academic concept of spreading this technology \u2013 called additive manufacturing \u2013 which is growing not only in Brazil, but around the world. It is a game changing technology, aptly called disruptive, of traditional manufacturing processes,\u201d Oliveira says. \u201cSo, the students and researchers who have had contact with this type of technology also help spreading this knowledge not only through the RCGI, but also among the players taking part in this process.\u201d<\/p>\n

According to the researchers, the new RCGI equipment and the laboratory where it will be installed will support the Brazil Additive Manufacturing Hub, which is an initiative of the Institute for Technological Research (IPT), created to spread the knowledge of this technology that is currently used more in the medical, aerospace, and automotive areas.<\/p>\n
