Objectives
THE COURSE IS AIMED AT PROVIDING THE KNOWLEDGE ABOUT INNOVATIVE ADDITIVE MANUFACTURING PROCESSES. 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. THEREFORE, THE KNOWLEDGE IS THOUGHT TO BE CRUCIAL IN THE ENGINEERING FIELD.
EXPECTED LEARNING OUTCOMES
KNOWLEDGE AND UNDERSTANDING.
KNOWLEDGE REGARDING THE CURRENT AVAILABLE PROCESSES OF ADDITIVE MANUFACTURING, THE MATERIALS FOR EACH TECHNOLOGY AND ANNEXED ADVANTAGES AND DISADVANTAGES; INTEGRATION OF THE THE ADDITIVE MANUFACTURING PROCESSES IN TRADITIONAL MANUFACTURING SYSTEMS; KNOWLEDGE OF THE OPTIMIZATION STRATEGIES FOR THE MECHANICAL PROPERTIES AND THE SELECTION OF ADEQUATE TECHNOLOGIES AND MATERIALS, DEPENDING ON THE FINAL COMPONENT; KNOWLEDGE OF POST-PROCESSES TREATING; KNOWLEDGE OF THE PROPERTIES OF THE MATERIALS UPON ADDITIVE MANUFACTURING.
APPLIED KNOWLEDGE AND UNDERSTANDING:
IDENTIFY THE PROPER ADDITIVE MANUFACTURING TECHNOLOGY TO BENEFIT A REDUCTION OF TIME AND COST, BASED ON THE FINAL PRODUCT. BE ABLE TO APPLY 3D PRINTING TECHNOLOGIES BY DESIGNING AND CREATING A COMPONENT WITH THE FUSED FILAMENT FABRICATION TECHNOLOGY; PLAN AND DESIGN THE MANUFACTURING JOB, EVALUATE THE MECHANICAL AND STRUCTURAL CHARACTERISTICS RESULTING FROM INNOVATIVE TECHNOLOGIES.
JUDGMENT AUTONOMY
DEVELOP NEW IDEAS AND SOLUTIONS USING THE ADVANTAGES OF ADDITIVE MANUFACTURE.
COMMUNICATION SKILLS
BEING ABLE TO ORALLY EXPOSE THE CONTENTS OF THE COURSE WITH PROPER LANGUAGE AND PREPARE AN ADEQUATE TECHNICAL REPORT ON DESIGNING A PART FOR ADDITIVE MANUFACTURING.
Prerequisites

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.UNISA.IT/.
Verification of learning
THE EXAMINATION CONSISTS OF A DISCUSSION WITH VALUTATION OF THE TECHNICAL REPORT AND A MANDATORY ORAL TEST. THE TECHNICAL REPORT IS AIMED AT ASSESSING THE KNOWLEDGE IN TEAM WORKING FOR THE TOPOLOGICAL OPTIMIZATION AND THE APPLICATION OF THE GUIDELINES OF DESIGN FOR ADDITIVE MANUFACTURING (DFAM), TO DESIGN AND PRODUCE A COMPONENT.
THE ORAL EXAM IS AIMED AT ASSESSING THE STUDENT'S KNOWLEDGE OF: 1) AM SYSTEMS AVAILABLE ON THE MARKET AND THE ADVANTAGES AND DISADVANTAGES OF EACH TECHNIQUE; 2) SPECIFIC PROPERTIES OF MATERIALS PRODUCED BY ADDITIVE MANUFACTURING TECHNOLOGIES; 3) BASIC PRINCIPLES FOR OPTIMIZING THE DESIGN OF MATERIALS IN ADDITIVE MANUFACTURING PROCESSES; 4) CONTROL OF POST-PROCESS TREATMENTS; 5) THE INTEGRATION OF AM TECHNOLOGIES WITH CONVENTIONAL ONES; 6) THE DEFINITION OF THE PERFORMANCE INDICES OF MANUFACTURING SYSTEMS IN STATIONARY OR VARIABLE CONDITIONS.
THE MAXIMUM SCORE AT THE DISCUSSION OF THE TECHNICAL REPORT IS 30/30. THE MAXIMUM SCORE FOR THE ORAL EXAM IS 30/30. THE FINAL MARK IS DETERMINED AS THE AVERAGE BETWEEN THE DISCUSSION OF THE TECHNICAL REPORT AND THE ORAL TEST; HONORS ARE AWARDED IF THE STUDENT SHOWS AUTONOMOUS PROCESSING SKILLS AND LOGICAL CONNECTION BETWEEN THE COURSE TOPICS. SUFFICIENCY IS ACHIEVED IF THE STUDENT SHOWS TO KNOW THE PRINCIPLES OF ADDITIVE TECHNOLOGIES
