Learning objectives
Knowledge and ability to understand (I Dublin Descriptor):
By the end of the course, the student will have integrated his or her basic knowledge of metallic and polymeric materials suitable for component fabrication using additive manufacturing technology. He/she will have gained awareness of issues related to additive manufacturing technologies. In particular, by the end of the course the student will be able to select appropriate materials and design and manufacture components by additive manufacturing.
Skills (II Descriptor: Ability to apply knowledge and understanding):
Through in-class exercises related to all program topics, the student will learn how to apply the knowledge gained in a design context. In particular, the student will practice additive manufacturing and the use of the simplest 3D printers.
Autonomy of judgment (III Dublin descriptor):
The student should be able to critically understand the characteristics and behavior of matter by evaluating its properties and suitability in relation to the intended applications. He/she will also have to process the relevant data to verify the required performance.
Communication skills: (IV Dublin descriptor)
At the end of the course the student should have acquired sufficient language skills, at least as regards the specific technological terminology of the teachings.
Learning ability (V Dublin descriptor):
The students who have attended the course will be able to deepen their knowledge of materials for additive manufacturing, through the autonomous consultation of specialized texts, scientific or popular magazines, even outside of the topics dealt with strictly in class. The laboratory experience gained will have the aim of introducing the student to the most recent developments in terms of research in the field of polymeric materials applied to additive manufacturing: the student should have acquired the basic knowledge and skills of the discipline to face, in the future, an autonomous deepening of these aspects.
Prerequisites
Basic knowledge of chemistry and materials science and technology
Course unit content
The module aims to provide the student with i) basic knowledge of Additive Manufacturing technology for metal alloys, ii) knowledge to evaluate the microstructure and mechanical properties of alloys produced by AM in as-built and post-heat treatment conditions. The first part of the course will be based on Additive Manufacturing technology for metal alloys, with a particular focus on powder bed processes and the microstructural effects induced by these processes on non-ferrous alloys. The second part of the course will focus on optimizing mechanical properties through heat treatments and basic characterization of metallic materials through laboratory activities.
Full programme
The module will focus on the following topics:
1) Definition of the Additive Manufacturing process (ISO/ASTM 52900) and description of the powder-based processes (process parameters and general characteristics)
2) Strengthening mechanisms of the metallic materials
3) Heat treatments
4) Metal alloys for biomedical, aerospace, and automotive applications: microstructure and mechanical properties (Al-Si-Mg, Al-Sc-Zr, Ti6Al4V)
5) Tensile test and hardness test
6) Metallographic preparation and optical microscopy
Bibliography
The slides presented during the course will be made available in PDF format on the Elly platform. Notes provided by the instructor and parts of articles suggested during the course.

Teaching methods
The knowledge and skills are acquired by the students, for each training area, through:
(i) Frontal lessons in the classroom using the projection of slides. The teaching material will be provided on the “Elly” platform (http://elly.scvsa.unipr.it);
(ii) Exercises and demonstration in the laboratory.
(iii) Educational visits and/or seminars.
The details in terms of CFU of the division of this structure are reported in the Syllabus of each module of the Laboratory.
Assessment methods and criteria
The evaluation of learning takes place through an assessment of knowledge structured as follows:
1) Written assessment of skill learning: a written examination will be conducted that corresponds to the assessment of skills acquired within each module pertaining to teaching. This will be a written examination with 6 open-ended questions in numbers proportional to the CFUs of the individual modules. The assessment will be made on a scale of 0 to 30. The grade will be considered sufficient if a grade of at least 9/30 is achieved for each module.
2) Oral assessment: those with a written assessment between 18 and 21 will have to take an oral examination. All others, provided they have at least a sufficient evaluation, may request to take the oral examination.
The vote of each laboratory will be unique and will represent the summary of the individual votes.
Other information
Class attendance is strongly recommended. Registration of attendance at teaching workshops will be made.
