Accurate 3D - Aumento de precisão e caraterização mecânica de peças funcionais impressas por 3D para apoio à produção

In component production industries, such as aeronautics, a large number of tools are needed to support production, which end up being single. Its production by conventional processes takes an average of about 5 weeks, resulting in high costs and interference in the series production process. 3D printing, which has been increasingly asserting itself as the production technology of the future, is currently extremely competitive for highly complex unitary parts, however it still has some limitations for more demanding applications due to the warping that the parts suffer during printing and inferior mechanical properties. In this project, it is proposed the development of methodologies to increase the geometric precision of printed pieces in polymeric materials by the FFF technique, through computational simulations, in order to compensate the predicted warpage. It is also intended to characterize the properties of various printed materials, depending on printing parameters, including mechanical resistance, fatigue and wear, analyzing in detail the way the material is deposited. This project, between the IPS and companies in the region with whom the IPS has a solid relationship, intends to take a significant step towards the serial printing of functional parts in final applications, also paving the way so that in the near future we can evolve to the printing of metallic materials.
