WASP- World’s Advanced Saving Project is a company born in 2012 in Massa Lombarda (Ravenna- Italy) that designs, produces and sells 3D printers Made in Italy all over the world. The wide range of WASP 3D printers has been developed to answer human needs: food, housing, health, energy, work, art and culture. Inspired by the Potter Wasp, which builds its own nest with material recovered from the surrounding environment, WASP was born with the aim of developing large-scale 3D printers, to build houses with natural materials and available on the territory. The main company target is to provide effective benefits to humans through technological innovation and research. In 2012 WASP presented its first printer, the Power WASP, but soon after the company characterized its range with the Delta line of small and large dimensions up to the generation of the Delta WASP Industrial line WASP 3MT, WASP 4070, and WASP 2040. Today the Delta WASP Clay line is the market leader thanks also to the experience gained in the architectural field. These new 3D printers Clay optimize the LDM system by 3D printing fluid-dense materials and industrial clays continuously and in large dimensions. In 2021, WASP has presented more technological advancements in the large 3D printers of the Industrial line and Clay line that meet the market demands for the extrusion of bio-polymers, super-technopolymers, recycled materials, pellets, natural material, and raw earth, and industrial clay.
