Rosswag Engineering, a leading supplier of special metal powders, high-quality components, and qualification services in metal 3D printing, has been certified by TÜV SÜD for the additive manufacturing of components made of 1.4404 (316L), according to the Pressure Equipment Directive (PED).

3D printing offers manufacturers of pressure equipment the opportunity to overcome the limitations of traditional manufacturing processes, implement complex geometric shapes, and produce devices in small quantities – economically. However, manufacturers face the challenge of proving the compliance of their additively manufactured products with the applicable legal requirements. To this end, TÜV SÜD has developed a certification program that considers the general safety requirements of the European PED 2014/68/EU.

Rosswag Engineering was one of the first manufacturers in the world to be certified by TÜV SÜD – in accordance with the PED – for the manufacture of AM components made of 1.4404 (316L). For this, the company completed the extensive testing and certification program in accordance with DIN 17026:2020. Essentially, the quality of the entire process is certified – from the consistency of the manufacturing processes to the internal processes for quality assurance and quality controls to the reproducibility of the mechanical-technological properties, considering the PED requirements. To meet the high quality demands of additively manufactured pressure equipment, more than 100 specimens were produced on the SLM 280 2.0 LPBF machine, and subsequently tested.

“We want to offer solutions to transfer more functional, optimized, and additive manufactured components into industrial applications. But to be able to apply innovative heat exchangers, for example, there was no alternative to certification according to the Pressure Equipment Directive,” said Gregor Graf, Head of Engineering at Rosswag GmbH.

“With our certification according to the Pressure Equipment Directive, we can also confirm the high quality, reliability, and safety of Rosswag GmbH’s additive manufactured products for the end user,” said Gunther Kuhn, Head of Product Management at TÜV SÜD Industrie Service GmbH.
