dissemination & sustainability

TecHUB 4.0
research agenda

Intellectual Outputs will be disseminated through scientific conference presentations, live demonstrations, professional workshops, industry reviews and state of the art articles.

Conference and Journal publications are targeted for sustainability of the intellectual outputs and project results.  The role of 3D Printing in in the educational process and the development of entrepreneurial skills will be investigated.

Other subjects like blended learning and creative thinking will also be addressed.

ABSTRACT

Since its introduction in the early 1990s Material Extrusion (MEX) has become the most popular additive manufacturing technology for a variety of applications. One of the reasons of its popularity amongst users is the affordability of the equipment, materials and the open source software. Given the large variety of combinations optimisation of MEX process parameters can be quite elaborate. The paper provides a method for optimisation of mass calculation using  multivariable regression analysis. Layer thickness, printing temperature and printing speed were considered the independent variables for a two level factorial experimental program. DOE was used to plan 12 sets of programs, out of which four were found to have  significant models. The four models were validated through measured and calculated responses.

ABSTRACT

Additive manufacturing is a worldwide trend and has been successfully adopted in a wide variety of domains. With applications ranging from automotive, aerospace, military, consumer goods  bioprinting and even wearable electronics, the need for trained workforce in additive manufacturing is in high demand. Academia all around the world is adapting to this new trend trying to develop new strategies in delivering suitable competences to their undergraduate, masters’ and PhD students. Such an initiative is the Erasmus+ project TecHUB 4.0 which brings together four complementary universities from Romania, United Kingdom and Poland. The main goal of the project is to bring together professors, industry specialists, researchers, managers, and entrepreneurs to deliver, using methods based on modern teaching technologies, especially on the use of web-based platforms and digital technologies – e-learning and interactive platforms, their knowledge to the young students wishing to become entrepreneurs in the additive manufacturing area. An Open Interactive Platform will be designed to be used equally by companies, by universities and by students, which will aggregate the demand and offer for internships developed in the scope of developing projects anchored in the day-to-day additive manufacturing business activity to solve concrete problems, but at the same time respecting all the economic constraints imposed on a business at beginning of its life.
