Course detail
Additive Technologies in Foundries
FSI-PTS Acad. year: 2023/2024 Summer semester
The course introduces students to basic approaches to data processing for models produced by the rapid prototyping (RP) method. They acquire basic knowledge of RP principles, including an overview of additive manufacturing (AM) methods applicable in foundry technology. They gain hands-on experience using AM for prototyping. The subject includes hybrid technologies, computer support for the production of molds and models, including quality control methodology and the economics of producing prototype castings.

Aims
In this subject, students will get acquainted with the preparation and use of data needed for 3D scanning of models and castings, for numerical simulations and virtual engineering. Students will learn about the basic methods and principles of the RAPID PROTOTYPING (RP) technology, including reverse engineering procedures (RE). They will get familiar with the selected modern technologies for manufacturing castings and process management methods with the application of the industry 4.0 principles. They will also learn model surfacing and smoothing procedures and methods for RP, molds and castings and they will get acquainted with the dimension and shape accuracy testing methods and metallographic and phase casting material assessment methods. Part of the subject will also be to obtain knowledge of the composition of production costs and the foundry production economy.
Students will acquire the knowledge and skills of 3D modelling (designing and making), rapid prototyping methods (RP), using computer technology for 3D measuring (scanning), numerical simulations of foundry procedures etc. Process management in selected foundry technologies including quality control and composition and production cost management in prototype production.
