3D printing for Bioelectronics and Biomedical Applications
After participation in this course, the student is able to: 1. describe the different approaches for state-of-the-art 3D-printing 2. develop and design a 3D model for stereolithographic printing applications 3. Perform a stereolithographic 3D-printing process including post-processing and verification of design parameters 4. Apply the printed structure in a biomedical or bioelectronics experiment.
The block course will start by introducing the field of 3D-printing including the biomedical and bioelectronic drivers for important applications. We will cover basic principles of different micro- and nanoscale 3D-printing strategies with a focus on stereolithographic methods. We will then give an in-depth introduction into the operation of state-of-the art 3D printers that are available for the lab course. The students will apply their knowledge for a given project involving the design, printing process and the use of the printed devices in a laboratory experiment. The actual project will be related to the fields of bioelectronics or biomedical engineering including cellular or robotics applications. Thus, the interdisciplinary course will combine aspects of engineering design, electronics, and biology.
Teaching and learning methods
The module will comprise an introduction into the 3D printing process with a lab application from the field of bioelectronics or biomedical engineering. During the lab course, the students will design, print, and characterize a 3-dimensional structure for a given application. Thereby the students will achieve a thorough understanding of the printing process and learn how to fulfill a given set of conditions for a specific application. In the subsequent experiments, the students will then learn to apply 3D-printed structures within a research environment. In combination, this will help the students to acquire the teaching goals, which are listed above.
Written lab report: 60% Lab performance and discussion: 40% The examination consists of a written report containing the content and results of the practical class (60%), as well as regular discussions with the assigned tutor (research assistant) about the progress of the experiments and resulting next steps (40%). The written report demonstrates the student’s ability to summarize the theoretical background of 3D-printing experiments for biomedical applications and to analyze and evaluate the results. The regular discussions with the tutor measure the student’s ability to follow an experimental concept within a given timeframe and identify challenges in 3D printing for biomedical and bioelectronics applications.
