Università Roma Tre

COURSE PURPOSE: The Special Technologies Course provides students with the basic knowledge to navigate unconventional manufacturing processes. Specifically, the course allows students to acquire knowledge of transformation processes with advanced technologies, such as laser, electron and ion beam processes, electro-erosion, chemical and electrochemical processes. It is, therefore, a complementary course to Mechanical Technology which, on the other hand, teaches about the traditional transformation processes of metallic materials only. The Special Technologies Course also includes elements relating to powder metallurgy processes. It also provides the knowledge base on rapid prototyping technologies. Finally, it provides the rudiments of so-called "green" technologies and initial indications on the aspects concerning safety in production processes.

COURSE PURPOSE: The Course in Plastics Processing Technologies provides students with the basic knowledge to navigate the plastics processing processes. Specifically, the course allows the acquisition of knowledge on the processing technologies of polymeric and composite materials, materials that occupy an increasingly significant weight in modern manufacturing processes. It is, therefore, a complementary course to Mechanical Technology which, on the other hand, teaches only about the conventional transformation processes of metals. The Plastic Materials Processing Technologies Course therefore includes elements relating to the extrusion and molding processes of the main plastic materials, as well as the forming processes of composite materials.
