A selection of sustainable materials are also used to introduce students to sustainable design. The built skis/board will be mechanically tested in the lab as well as together out in the field on a ski day and evaluated from various perspectives. Students can keep their personal built skis/boards after the course.
Content	This practical ski/board design and building workshop consists of planning, designing, engineering and building your own alpine ski or snowboard. Students learn and execute all the needed steps in the process, such as engineering design, CAD, material selection, analysis of the mechanical properties of a composite layup, fabrication, routing wood cores, 3D printing of plastic protectors, milling side walls from wood or ABS plastic, laying up the fibers from carbon, glas, basalt or flax, laminating with resins, sanding and finishing, as well as laser engraving and veneer wood inlays.

Abstract	This course attempts to prepare the student for a job as a materials engineer in industry. The gap between fundamental materials science and the materials engineering of products should be bridged. The focus lies on the practical application of fundamental knowledge allowing the students to experience application related materials concepts with a strong emphasis on case-study mediated learning.
Learning objective	Teaching goals: to learn how materials are selected for a specific application to understand how materials around us are produced and manufactured to understand the value chain from raw material to application to be exposed to state of the art technologies for processing, joining and shaping to be exposed to industry related materials issues and the corresponding language (terminology) and skills to create an impression of how a job in industry "works", to improve the perception of the demands of a job in industry
Content	This course is designed as a two semester class and the topics reflect the contents covered in both semesters. Lectures and case studies encompass the following topics: Strategic Materials (where do raw materials come from, who owns them, who owns the IP and can they be substituted) Materials Selection (what is the optimal material (class) for a specific application) Materials systems (subdivisions include all classical materials classes) Processing Joining (assembly) Shaping Materials and process scaling (from nm to m and vice versa, from mg to tons) Sustainable materials manufacturing (cradle to cradle) Recycling (Energy recovery) After a general part of materials selection, critical materials and materials and design four parts consisting of polymers, metals, ceramics and coatings will be addressed. In the fall semester the focus is on the general part, polymers and alloy case studies in metals. The course is accompanied by hands-on analysis projects on everyday materials.
