3D printing (3DP) is an emerging technique for direct conversion of 3D computer aided designs into physical objects using a variety of approaches. 3DP technologies are simple and flexible processes that allow for the creation of very complex and customizable 3D objects in just a few process steps. This seminar gives an overview of the particularities in the structural integrity of 3D printed components revealed by state-of-the art structural characterization. You will get to know the differences in mechanical properties of 3DP parts with respect to conventional fabricated ones and explore how they fail. You will learn about the microstructural reasoning for this behaviour and discuss in groups how general design guidelines can be developed. This knowledge is key to leverage opportunities in shape, hierarchical, functional and material complexity amenable to 3DP but also to consider the limitations of what can be accomplished. Basic principles for design for 3D printing will be explained in this course.
Methods
The course is interactive with short lectures and subsequent discussions on the individual topics described in the course content. An introduction to the group project will be given on day one of the course. Indidividual guidance to the group projects will be given on day two and the students will start their individual print jobs themselves giving them hands on experience on 3D printing. Mechanical tests will be conducted together with the entire class on day 3.
Dependent on the number of participants, groups will be divided into 3-6 persons. All groups have to work on a project, where their knwoledge and competence on Design for 3D printing as well as their capabilities in the parts' mechanical characterization will be assessed. The students have to compile a report that is due 1 week after the end of the course. It has to be submitted online on TISS. In addition to the project, the students will have to complete a written test consisting of multiple choice questions.
Not necessary
The studens should have basic knowledge in Mechanics, Materials Science, Thermodynamics and Chemistry. Pre-knowledge in Computer Aided Design (CAD), Finite Element Modelling (FEM) and Programming (Matlab and Python) are of advantage.
