	Objectives
	THE COURSE IS AIMED TO PROVIDE THE KNOWLEDGE ABOUT INNOVATIVE ADDITIVE MANUFACTURING PROCESSES AND THEIR INTEGRATION INTO TRADITIONAL MANUFACTURING THESE PROCESSES ARE GAINING INCREASING INTEREST INDEED, IN A NUMBER OF FIELDS, THEREFORE THEY REPRESENT THE FUTURE OF THE INDUSTRY 4.0, AS THEY PROVIDE OPERATIONAL FLEXIBILITY, REDUCTION OF TIME AND WASTE IN THE FRAME OF GREEN MANUFACTURING. IN PARTICULAR, THE COURSE IS AIMED TO PROVIDE KNOWLEDGE REGARDING MANUFACTURING OF COMPLEX MECHANICAL COMPONENTS, PLANNING AND DESIGN OF MANUFACTURING, EVALUATION OF THE MECHANICAL AND STRUCTURAL PROPERTIES RESULTING FROM SUCH INNOVATIVE TECHNOLOGIES. TO THIS PURPOSE, ACTUAL CASE STUDIES ARE PRESENTED AND DISCUSSED. THE COURSE IS AIMED TO PROVIDE KNOWLEDGE REGARDING MANUFACTURING OF COMPLEX MECHANICAL COMPONENTS, PLANNING AND DESIGN OF MANUFACTURING, EVALUATION OF THE MECHANICAL AND STRUCTURAL PROPERTIES RESULTING FROM SUCH INNOVATIVE TECHNOLOGIES. TO THIS PURPOSE, ACTUAL CASE STUDIES ARE PRESENTED AND DISCUSSED. SINCE SUCH PROCESSES ARE TYPICALLY REFERRED AS DISCRETE AND SINCE THEY ARE EXPECTED TO REQUIRE A SERIES OF POST-PROCESSING OPERATIONS, A MORE IN-DEPTH ANALYSIS OF MANUFACTURING SYSTEMS IS ALSO PROVIDED IN THE COURSE, THEREFORE A NUMBER OF APPROACHES TO EVALUATE THE PERFORMANCES ARE PRESENTED, INCLUDING QUEUEING THEORY.

	Teaching Methods
	TEACHING INCLUDES THEORETICAL CLASSES, NUMERICAL EXERCISES AND LABORATORY, WITH THE OPPORTUNITY TO TAKE PART IN JOB PLANNING AND RUNNING OF THE PROCESSES, TO THE PURPOSE OF OBTAINING REAL PARTS. DURING THE COURSE EDUCATIONAL VIDEOS AND SIMULATIONS ARE EVEN PRESENTED TO THE PURPOSE OF EASIER UNDERSTADING OF THE TOPICS. ADDITIONAL MULTIMEDIA AND SHORT OUTLINES OF THE CONTENTS ARE AVAILABLE AT HTTP://ELEARNING.DIMEC.UNISA.IT/.
