Savio, 3D printing in the design of textile machinery
Savio Textile Machines company leader in textile machinery design with the help of 3D printing
Savio Macchine Tessili S.p.A., today a leading company in the sector of machines for finishing yarns, was founded in 1911, when Marcello Savio founded a small mechanical workshop for the repair of looms. In the forties the first company’s first production machine.
Since then there have been many achievements and today, in addition to the Italian plant, Savio Macchine Tessili has offices in China, India and the Czech Republic, for a total of 780 employees.
In order to combine this history and company tradition with new technologies and to continue to guarantee product excellence, about ten years ago, the company’s interest in 3D printing was born. Given the need to create prototypes of some parts for new projects and the need for greater precision in the production of details, Savio initially turned to the 3DZ printing service.
In this way we have had the opportunity to test the type of printer that best suits our needs. We still refer to 3D printing services for the production of large numbers. The collaboration with 3DZ continued with the purchase of the ProJet 2500 Plus and Form 2 from Formlabs, which uses stereolithography technology and has been awarded the Best TopWorld 2015 3D Printer.
Some prototypes made with the Projet 2500
Gianfranco Caufin, 3DZ’s sales representative, explains:”Unlike many other printers, the Projet 2500 Plus works autonomously, without the need for control or a dedicated PC and is ready for operation 24/7. Thanks to its precision and high productivity, this machine accelerates the production of components and prototypes. And it is precisely because of these characteristics that, even in the case of Savio, the printer is used on a daily basis “.
3D printing has become an integral part of the design phase of Savio machinery. The company confirms:”We use 3D printing every day, mainly during prototyping. But we have not limited ourselves to this area: where the material has allowed us to do so, we have pushed ourselves to produce parts in 3D for some machines to be tested at the end customer’s premises. If there is a possibility of printing with different blends in the future, we believe that, in some cases, 3D printing may even replace the need for some mechanical machining operations or moulds.”

From left to right: suction manifold; lid that, thanks to its transparency, allows you to see the behavior of the wire inside an machine; hinge, a detail that rotates around 8000/9000 revolutions per minute and serves to stretch the cotton fibers.
3D printing in the design of textile machinery: benefits
In the case of Savio, the most appreciated advantages of 3D printing are the possibility to test directly on the machine and quickly the new solutions, the need to not have to take up again and again the moulds necessary for mass production and the possibility to realize the final mould only after the prototype has satisfied the quality and reliability tests. As a result, the lead times for the production of the designed parts have been significantly reduced.
