In the product development process, both virtual methods and modern prototyping are important tools for making the properties of the resulting product tangible early on in the development / design phase and, if necessary, optimizing them in this early phase. 
In line with modern, agile methods of product development, the development time is shortened. The targeted access to the resulting data, the networking of digital product models and the linking to current manufacturing technologies such as 3D printing, laser sintering, laser cutting or fiber-reinforced FDM enable the creation of initial prototypes almost parallel to the digital design.

The total workload for the module is 135 hours (see also "ECTS credit points and grading").

The term "laboratory activity" is also understood to mean the lecturer-led practical approach to learning and the testing of selected production processes. 

• Homework / Assignment

 As part of the term paper, the result of a self-developed prototype is documented and presented. The developed product is also created as a "real prototype" using suitable production processes that are available in the laboratory.

Completed bachelor's degree in mechanical engineering, automotive engineering or similar.
Basic knowledge of common CAD and CAE tools is required. 

Students at Osnabrück University of Applied Sciences who have successfully completed this module

have an in-depth understanding of the benefits of modeling real requirements such as assembly and manufacturing inaccuracies and other deviations from nominal dimensions
know further possible uses of CAE tools such as kinematics simulation, qualitative determination of loads in the design stage

Students at Osnabrück University of Applied Sciences who have successfully completed this module

know how to prepare virtual prototypes for real prototyping
know selected innovative processes for real prototyping
have experienced the differences between digital and real prototypes by means of an application example.

Students have an in-depth understanding of the abstraction for virtual prototypes and the adapted, production- and load-oriented design for selected manufacturing processes that are suitable for the rapid creation of prototypes.

The students, "i.e. all gender of students", can independently create suitable models for virtual prototypes and make targeted decisions about suitable processes for real prototypes. 

The introduction of agile product development methods and the simultaneous professional use of virtual and real prototypes accelerates the development process: these innovations therefore shorten the "time to market". 

Students can critically reflect on decision-making situations and the associated issues with regard to the economic efficiency of using virtual or real prototyping methods.

Students will be able to independently carry out existing and future challenges of transferring findings from the production and testing of virtual and real prototypes to finished products.
