New lightweight optimization method applied in parts made by selective laser sintering and polyjet technologies

[EN]The continuous evolution of materials and technologies of Additive Manufacturing (AM) has led to a competitive production process even for functional parts. The capabilities of these technologies for manufacturing complex geometries allow the definition of new designs that cannot be obtained with any other manufacturing processes. An application where this capability can be exploited is the lightening of parts using internal structures. This allows to obtain more efficient parts and, at the same time, reduce the costs of material and manufacturing time. A new lightweight optimization method to optimize the design of these structures and minimize weight while keeping the minimal mechanical properties is presented in this paper.

Materiales didácticos interactivos en Ingeniería de Fabricación

[EN]This work is part of a methodological renovation project from Ingeniería de Fabricación Innovative Education Group, from University of Las Palmas de Gran Canaria. It has developed learning materials for courses in Manufacturing Engineering that can be used in several degrees. The first learning material, it was decided to take a plastic injection mould as a teaching resource. Abundant information generated has been used to develop an interactive electronic publication. This learning material has been chosen by the Publishing and Scientific Diffusion Service from this University, as a new line of work in publications of educational innovation. The group is developing more training materials on other manufacturing processes as well as cross-contents dimensional tolerances in the ISO GPS system. All this work has generated a lot of educational resources for both laboratory practices and interactive multimedia documents.
