Additive manufacturing is deeply modifying several industrial activities promoting new technological opportunities. In this background, the teaching “Polymers for Additive Manufacturing” provides the basics for a scientific approach to 3D printing. The students will study the chemico-physical processes involved in the additive manufacturing technologies, the use of software and FDM and DLP 3D printers.

The teaching faces different processes involved in additive manufacturing and provides the basics of:
a) fundamentals of CAD and slicing software;
b) the main properties or polymers employed in 3D printing technologies;
c) the use of DLP and FDM printers;
d) the properties of manufacts printed with FDM and DLP techniques.
The teaching Polymer for Additive Manufacturing aims to providing practical and theoretical knowledge on 3D printing (focusing on FDM and DLP technologies). After the course the students will know the working principles and applications of the main 3D printing technologies and will acquire practical experience with both software and hardware employed for polymer additive manufacturing. In details, the students will study the materials employed in filament deposition (thermoplastic polymers and their properties) and photopolymerization (radical mechanisms and issues related) and in powder sintering 3D printing. They will also acquire detailed knowledge on the different printing technologies and will learn to define pros and cons as well as uses of the technologies for different applications. The students will finally be able to correlate the properties of printed manufacts with the printing conditions and the material.
The students must possess knowledge related to polymeric materials. For this reason it is required to have undertaken the exam of the teaching “Scienza e tecnologia dei materiali polimerici” (for student of the University of Genova) or analogous (for students from other universities).
The teaching consists of both lectures in classroom (24 h) and laboratory activities (13 h). The lectures will present basics on the chemico-physical properties and processability of thermoplastics and thermoset polymers and will focus on the detailed description of additive manufacturing technologies (FDM, DLP, SLA, SLS). 4 laboratories will then allow the student to put in practice knowledge acquired during the lectures, employing 3D printer and related software to explore the effect of operational parameters on the quality and properties of the printed manufact. During the laboratory activities, depending on their number, the students may work in small groups.

second semester: last week of February / first week of March. For more details / updates check https://corsi.unige.it/9020
The student will discuss an original power-point presentation on a topic related to the teaching and will be asked to describe the theoretical aspects of the related 3D printing technique. The student will select the topic with the help of the teacher among those reported in the scientific literature. The presentation should have an approximate length of 15 to 20 minutes. The student must demonstrate comprehension of the physical/chemical/technological fundamentals related to the topic selected and to use appropriate technical vocabulary. The clarity of presentation and ability to answer questions will be also evaluated.
The purpose of the exam is the verification by the commission of the achievement of the educational objectives of the teaching. Otherwise, the student will be invited to deepen the study and to make use of further explanations by the teacher before taking the exam again. To ensure correspondence between the topics of the exam and the educational objectives of the teaching, the detailed course program is uploaded to AulaWeb and/or on Microsoft Teams and illustrated at the beginning of the lessons, so that students can verify compliance. During the assistance to the laboratory exercises, the teacher will evaluate the effective involvement of the individual students in the experience and the ability to carefully carry out the experimental measurements. The individual oral exam will allow to ascertain in detail the achievement of an adequate level of knowledge in the field of 3D printing of polymeric materials, and in general the ability to deduce relationships between printing conditions and properties obtained, also on the basis of knowledge acquired in previous polymeric courses.
For students with disabilities or with DSA, the exam methods are aligned with the University regulations for carrying out profit exams (https://unige.it/disabilita-dsa).
