Prototyping with 3D Printing – students apply “Learning Lab” know-how for their bachelor thesis

Written by Prof. Dr. Joachim Günther (HM)

Starting March 2020, the COVID-19 pandemic caused extensive restrictions. Even though further Learning Lab POW workshops (‘Print Your Own World’) weren’t held, students kept utilizing their know-how and realizing new products. Figures 1-3 show functional models and prototypes that were the outcome from various bachelor theses.

One important decision upfront is which prototype components should be printed and which ones should be bought. Components such as shafts or steel pins are cheaper and quickly acquired in DIY supply stores.

Figure 1: Cardan joint that is able to transfer rotation and torque from a driveshaft to an output shaft, even if both shafts are positioned angularly.

Below, two mechanical functional models integrating 3D printed components are displayed.

Figure 2: Functional model with two cardan joints that are arranged consecutively. Thus, the torque in between the shafts that have offset can be transferred. One common application is found in machine engineering.
Figure 3: Gear range from a drive shaft and a pulley. These basic gears were used in mediaeval times as powertrain for water-powered mills.

These bachelor theses were super-visioned by Prof. Dr. Joachim Günther (Hochschule München, Faculty 09, Engineering Economics). For further information please contact me.

From the modeled process to a digitized workflow: the new virtual workshop “Process Management Fundamentals” (PMF)

Due to the special Covid19 situation, the latest Learning Lab was developed as a virtual workshop format in the current summer semester 2020: the workshop “Process Management Fundamentals” (PMF).
This allows processes to be made comprehensible, self-directed and experienced collaboratively even in distance learning. In the new workshop by professor Dr. Holger Günzel and Dr. Lars Brehm from Hochschule München University of Applied Sciences, processes are not only modeled. In addition, the execution is checked by simulation and the transfer to automated workflows for the execution of the processes: Forms can be filled out, emails sent or documents generated. By making the results directly visible, the gap that often exists between theory and practice is significantly reduced: The ability to easily understand existing process models is complemented by the ability to create your own models.

Workshop PMF in Action

Initially, the workshop was used in the summer semester 2020 with 20 students in the Bachelor of Business Administration. For this purpose, the proven tools such as Zoom and Breakout Sessions, Nuclino as a collaboration tool and Signavio as a cloud system for process modeling were used.

New stream “HAT – Home Automation with Internet of Things” is now available

In the winter semester 2020/21, the new stream “HAT” (Home Automation with Internet of Things) was already initially executed in the Master of Business Administration “Applied Business Innovation”. The stream shows the technical fundamentals and possibilities of the Internet of Things (IoT). Using the example of Smart Home, sensors and actuators are linked together.

The participants, who mainly started without a technical background, do not learn IoT theoretically, but build a larger case based on the single-board computer Raspberry Pi and various sensors. They read out values, control output devices and graphically create and operate data-based processes using the Node-Red automation tool. Furthermore, the participants learn about and use the MQTT (“Message Queue Telemetry Transport”) protocol.
