Course detail
Additive Technologies
FSI-ZAT-A Acad. year: 2024/2025 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.
