Course detail
Additive Technologies
FSI-ZAT Acad. year: 2020/2021 Winter semester
The course introduces students to the progressive area of additive manufacturing of metal, plastic and construction products. Students will obtain practical experience with production simulation and data preparation for 3D printing. Attention is paid to understanding of design rules, technological limits and production chain of additive manufacturing. Course integrates the knowledge acquired in courses focused on materials science, CAD modeling, FEA and simulation and design of machines and mechanisms.

Knowledge of CAD systems (CATIA, Creo Parametric, Rhinoceros, Inventor).
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures and software tools. Teaching is supplemented by laboratory work oriented to practical tests, measurement and data evaluation.
Assesment methods and criteria linked to learning outcomes
Course-unit credit is awarded on the following conditions: presentation of results achieved in laboratory exercises (max. 30 points).
Examination conditions:
<p>- passing the theoretical test (max. 70 points),</p>
<p>- a total of up to 100 points can be earned,</p>
<p>- the resulting classification is determined by the ECTS scale.</p>
Aims
Graduates will be able to design, process and produce parts using additive manufacturing. They will understand design rules, production limits and use of non-traditional design elements such as lattice structures.
Specification of controlled education, way of implementation and compensation for absences
Attendance at lectures is recommended; attendance at practicals and laboratory practicals is obligatory and checked by the lecturer. Compensation of missed lessons depends on the instructions of course supervisor.
