To reach the objectives of the project, 2 different research grants were activated through the University of Padua. he first one, headed by Desamanera, concerned the development of a smaller 3D printer. The fellow Engineer Matteo Bergonzoni, worked under the supervision of the Machine Design Professor Giovanni Meneghetti of the Department of Industrial Engineering. The other research grant, headed by Desamanera and Palladio Concept, focuses on the study of the reference market and the development of related communication activities. The fellow Dr. (PhD) Mauro Capestro worked under the supervision of Eleonora Di Maria, Professor of Economics and Business Management of the Department of Economics and Management “M. Fanno”, either Professor of the University of Padua. The project also included the activation of a third grant, with Mykra as lead company and the Department of Information Engineering as institutional partner, concerning the development of a software for the management of the 3D design. This grant was not activate, and Mykra handled the development of the software.
Engineer Matteo Bergonzoni designed a powder bed 3D printer with a smaller printing area than the first version. The designed printer – Desa 1 60.60 – presents an innovative print head, with a reduced minimal voxel dimension (unit of volume measurement, three-dimensional counterpart of the two-dimensional pixel and index of greater definition), moving from 5,7 mm to 3 mm, with evident increase of printing precision. Thanks to the greater definition achieved, it will be possible to significantly reduce post-production work and, as consequence, costs.
In conclusion, through this research grant, Desamanera s.r.l. has been able to build the first 3D printer for sale, acquiring further know-how in the design, construction and subsequent CE certification processes.
