lead-free piezo electric materials for 3D printing

Offentlig prosjektsammendrag

The 3DPIEZO project will develop a manufacturing chain for lead (Pb)free piezoelectric devices for ultrasonics and other applications. 3D printing and multilayer lamination will be the principal manufacturing methods, applying high performance leadfree piezoelectric ceramics. All critical steps of the manufacturing chain will be developed and demonstrated at TRL 6. Optimised versions of at least two different materials systems will be applied: bismuth sodium titanate (BNT) and potassium sodium niobate (KNN). The consortium consists of two SMEs and one research organisation: Ceramic Powder Technology AS is a Norwegian producer of advanced ceramics powder by spray pyrolysis, CERHUM S.A. in Wallonia is a specialist in 3D printing of ceramics, and SINTEF is the largest research organisation in Norway. To guide the project and provide component designs, 3DPIEZO will have an Industrial Advisory Board (IAB) with representatives from companies that use piezoelectric components in their products or services.
