The SIEGENIA technology camp enters its 2nd round – about marble runs and MINT

From July 8 to 11, 2024, the 2nd SIEGENIA Technology Camp took place at the SIEGENIA GRUPPE in Wilnsdorf-Niederdielfen. 8 pupils from Niederdielfen secondary school worked with trainees from the SIEGENIA GROUP, Team Fab Lab from the University of Siegen and FRids e.V. built and 3D-printed marble runs. The low-threshold activity was designed to get children interested in STEM subjects and introduce them to technical professions.

Elon Musk’s laptops, 3D printers and satellite internet were brought from the Fab Lab in Siegen to the training center to provide the necessary infrastructure. This concept proved to be very successful at the 1st SIEGENIA Technology Camp during the Easter vacations. Over four days, the children were taken from 0 to 100 – they became experts in topics relating to additive manufacturing, reverse engineering and design. The whole thing revolved around the construction of marble runs – what to do if parts of the run are suddenly missing? Measurements had to be taken with calipers – accurate to two decimal places. The measurements were then recorded on paper sketches. In the final step, the sketches were converted into digital drawings and printed out using the 3D printer.

FRids e.V. once again provided support with its many years of experience in youth work. Four energetic trainees from the SIEGENIA GROUP looked after the children and provided guidance at the training center. Machines such as the band saw in particular need to be looked after, because it’s not just about 3D printing. The entire training center could be used to solve the tasks. As part of the “EnvironMINT” project funded by the Federal Ministry of Education and Research, the Fab Lab team at the University of Siegen investigated the conditions for the success of good STEM education. “We want to enable cool STEM formats in the region that provide low-threshold access to technical topics and at least do not obviously have to do with “learning”. “Kids are already learning enough at school,” says Marios Mouratidis, Head of the Fab Lab at the University of Siegen. In this format, the partners placed great emphasis on self-determined, problem-solving and creative action on the part of the participants. While the basics were taught after just 1-2 days, the young people were then able to use the remaining time creatively and produce their own components for the marble runs.

On the last day of the technology camp, a closing event was held to which the parents of the participants were invited. Here, the young people had the opportunity to present their results.

The technology camp is organized in cooperation with Nina Herter and Sven Wiechmann from the SIEGENIA GROUP, Marios Mouratidis, head of the Fab Lab at the University of Siegen and Ulrike Monreal from FRids e.V.. The partners plan to continue promoting STEM in Siegen-Wittgenstein in the future.

On Thursday, July 11, the parents of the participants were invited to a presentation of the results.

Train-The-Trainer Workshop for SIEGENIA trainees at the Fab Lab Siegen

From the 25th to the 28th of March, a technology camp will take place at the SIEGENIA Ausbildungszentrum, which we are organising together with the SIEGENIA GROUP and FRids e.V.. The technology camp will give pupils from regional schools the opportunity to learn the basics of 3D-modelling and 3D-printing.

In order to provide the students with the best possible support, seven motivated trainees who work at SIEGENIA in the toolmaking and mechatronics departments were introduced to 3D printing in a train-the-trainer workshop here at the Fab Lab last week. Over the course of two days, our two colleagues, Marios Mouratidis and Jonas Kosiahn, taught the trainees how the technology works and how they can design and print their own models.

At the beginning of the workshop, the trainees were given an introduction to 3D printing and the modelling software TinkerCAD. Based on that, they were able to complete their first task: they independently modelled SIEGENIA key chains in TinkerCAD and then printed them.

The trainees then worked with a ball track system and designed and printed spare parts. The trainees had the task of recreating individual parts of the ball track system in TinkerCAD and then printing them using our 3D printers. Thanks to the practical approach in the workshop, the trainees were able to apply the knowledge they had acquired directly and are now ready for the technology camp!

We are delighted to be able to support STEM education in the region with our collaboration partners, the SIEGENIA GROUP and FRids e.V.. We really enjoyed the workshop and look forward to seeing how the trainees pass on their newly learnt skills to the pupils at the upcoming technology camp!

DRK x Fab Lab Siegen: 3D-Printing and Robotic Workshops for young people!

Fab Lab Siegen is not only a space for creation, but also for knowledge transfer. In our Fab Lab, we want to give everyone access to technology and knowledge. Since mid January 2023, we have been welcoming young refugees from Ukraine once a week (fridays from 4:30 pm to 6:30 pm).

Together we try out different technologies. So far, we were able to get to know 3D printing, laser cutting and robotics as well as programming with the Calliope Mini. We also held a PC-builder workshop where the participants were taught how to dis- and reassemble a computer. Through hands-on activities including play-doh modeling, Tinkercad design sessions and 3D printing projects, participants can bring their ideas to life. The creations span from protective cases for the Calliope mini microcontroller, Batman-themed rings and stylish key chains, all the way to meticulously crafted miniature cars.

Using a digital hangman game, developed by Hina Firdaus, we were able to teach the children fundamental programming skills. These first experiences paved the way to showing them further programming concepts like loops, conditional statements and variables.
With this knowledge we were able to realize exciting projects, e.g., a light sensor-equipped scooter, a functional traffic light simulation and even a miniature piano that responds to its programming inputs.

Thanks to funding from the Bürgerstiftung Siegen, we were able to organize and run this series of workshops in close cooperation with the DRK Kreisverband Siegen-Wittgenstein e.V.. So far, we have held more than 35 sessions, teaching more than 20 enthusiastic participants about the technologies in our Fab Lab.

The workshops are led by our team, especially Hina Firdaus and Marios Mouratidis. In addition, we have dedicated volunteers, including among others the honorary translators Anastasiya Nazarava, Gkiorgki Tataridis and Sonal Seth as well as technical support from Florian Anderes and Mallikarjuna Reddy. All of them support our workshops, ensuring that participants have an enjoyable and inclusive learning experience.

In our Fab Lab, we are committed to creating a safe environment where people can learn and grow together with us.
We’re looking forward to the upcoming weeks! If you are interested in helping, feel free to contact Sara Schneider via E-Mail (). We are still looking for more helpers who would like to shape the program with us.

Exciting Fab-Lab-Workshops at the MINT-Mitmachtage 2023

From the 12th-14th of September 2023, the MINT-Mitmachtage took place, where local pupils had the opportunity to get to know the exciting world of STEM fields (mathematics, computer science, natural sciences and technology). Of course, we wouldn’t miss the opportunity to take part in such an event, because it is very important to us to support STEM education and to show pupils how exciting these fields are and what kind of things you can design and create yourself. We have often had the opportunity to work with schools and make our lab available as an out-of-school educational space. This enables pupils to learn about interesting new technologies and realise their own creative projects.

For the MINT-Mitmachtage we prepared two exciting workshops for the pupils: they had the opportunity to learn microcontroller programming with a Calliope Mini kit or to dive into the world of 3D printing.

The 3D-printing-Workshop started with an introduction explaining, among other things, the structure of a 3D printer and the process of additive manufacturing, which is the process of building a model layer by layer. We then taught the pupils the basics of 3D modelling as well as the printing process and introduced them to the modelling software TinkerCad. It is free and open source, enabling the pupils, e.g., to continue modelling independently at home. After that, they were well prepared to work on their own little projects. They designed their own key chains and then printed them three-dimensionally in the DIGITALUM bus using our Prusa i3 MK3S and MK3S+ printers. They also had the opportunity to take a look at the technologies in the bus, e.g., a virtual reality station, a thermoforming machine, a laser cutter, a plotter and a soldering station.

In the Microcontroller-Programming-Workshop, the pupils learned how to give instructions to microcontrollers using block code. We showed them the importance of programming and what it can be used for, e.g., creating websites and developing operating systems. Electronic devices like mobile phones and washing machines or also traffic lights only work because of their programming. Additionally, the pupils were taught basic algorithms and the science behind programming in a playful manner. In the practical part of the workshop, the children were able to actively program something with the Calliope Mini kit. At first, they connected the microcontrollers and opened the corresponding browser version of the program “Open Roberta Lab”. They were able to choose whether they wanted to program a traffic light or a mini piano, but also had the freedom to contribute and realize their own ideas.

In total, over 1000 children took part in the MINT-Mitmachtage. We would like to sincerely thank the Regionales Bildungsbüro des Kreises Siegen-Wittgenstein for organising the event. We enjoyed giving the workshops and hope that we were able to fill many pupils with enthusiasm for the exciting world of STEM fields!

Project Day with the Gymnasium auf der Morgenröthe

On September 15, there was a lot going on at the Fab Lab: students from the Gymnasium auf der Morgenröthe visited us again. They spent the morning here at the Lab together with their teacher, Stefan Schramm, as part of a project day. The reason for this project day was the upcoming school fair celebrating the 50th anniversary of their school, for which each class had to prepare a stand.

The students had therefore decided to offer a wheel of fortune game with prizes. In order to plan and realize their idea here at the Lab, the students were divided into three groups.

The first group took on the task of designing and printing various prizes for the wheel of fortune game. This is where our 3D printers came into play. Different key chains as well as shopping cart chips were printed with the help of our 3D printer farm.

The second group designed and built the wheel of fortune itself. It was produced on our large CO2 laser cutter. The last group had the equally important task of documenting the entire day. The Lab Tour and the 3D printing process as well as the laser cutting, everything had been documented in the form of a video. You can watch the video here:

Overall, it was a successful project day with amazing results! It was great to see how committed and creative the students were in mastering the tasks and how well they worked together as a team. We are happy to have been able to support the students in their preparations for the school fair celebrating the 50th anniversary of the Gymnasium auf der Morgenröthe. We hope that the fair was a great success!

User-Story: Realization of a Planning and Development Project at the Fab Lab

Four students realized their planning and development project in the Fab Lab as part of their studies. This type of project is offered as a course as part of the Mechanical Engineering Program of Faculty IV at the University of Siegen. In this course, students work in groups on innovative technologies and concepts, which they present in a plenary session and document in a final report.

The goal of this project was to design a test rig for rubber bearing measurements in the chassis that can test all six degrees of freedom, since the current test rig of the Institute of Automotive Lightweight Design at the University of Siegen is not capable of doing so. The students focused on measuring U-bearings and RU-bearings.

In order to be able to realize the concept they developed, they needed bearing supports that would hold the various bearings when subjected to the test forces. To do this, they developed a model for a U-bearing support and an RU-bearing support and then printed them three-dimensionally using one of our Prusa printers in the Fab Lab.

printed support for a RU-bearing

The respective bearings can be attached to the support with the help of four screws. In order to be able to screw the bearing supports to, e.g., a base or adapter, they have eight holes on each side. This allows them to withstand any load, whether translational or rotational. Both bearing supports can be mounted to the required motor – linear lifting cylinder or three-phase motor – depending on the spatial direction to be measured, and can be screwed to necessary aids such as rails, rollers, an adapter or a rotatably mounted table.

On the drawing you can see an exemplary test rig. This shows how the printed bearing supports, developed by the students, can be used in a translational measurement with the linear stroke cylinder and in a rotational measurement with a three-phase motor.

We are happy that the Fab Lab can support students in their studies. So, if you also have a project in mind – whether as part of your studies or personal – just come by during our opening hours!

Fab Lab Siegen visits Porto as part of the ‘Co-Creation Hub’

This year, ATHENA European University has introduced the ‘Co-Creation Hub’. It serves as a platform to connect Fab Labs, Makerspaces and Design Factories and to promote joint projects and collaborations.

ATHENA, a union of medium-sized higher education institutions from nine European countries, including the University of Siegen, aims to provide inclusive, innovative and high-quality international education opportunities that always take the needs of the global market into account.

As part of the ‘Co-Creation Hub’, on June 29-30, 2023, an intensive workshop was held at the Design Factory in Porto, where ATHENA members were able to talk about their current projects and activities, but also challenges they are facing.

The participants of the workshop in Porto

Gloria Yap Basoeki from the Fab Lab Siegen also participated in the workshop and presented our Fab Lab as well as our guiding principles, the main points being our user-focused approach and the fact that the use of our Fab Lab is free of charge. This is because we pursue the goal of democratizing technology and making it accessible to all.

Gloria presenting the Fab Lab Siegen and its guiding principles

Participants also began to design a pilot program that aims to help ATHENA students to solve real-world problems using Fab Labs and Makerspaces (e.g., CNC machines or 3D printing). The pilot program is expected to be operational by the 2024 spring semester.

In addition to the workshop, Gloria visited five partners from three EDIHs (European Digital Innovation Hub) in Portugal with Robert Fischbach, research associate at the University of Siegen, to learn more about their structural organization and explore possibilities for future collaborations.

An evening full of nostalgia – The Fab Lab Game Night Vol. III

It was that time again! The Fab Lab Game Night Vol. III took place in collaboration with Startpunkt57 and the Entrepreneurship Center of the University of Siegen on July 11, 2023 under the theme “Don’t Stop Gaming” and exceeded all our expectations. The Fab Lab opened its doors for an unforgettable evening full of games, music and good vibes.

Four different consoles were ready to make gamers’ hearts beat faster. The Nintendo Switch offered a selection of the latest games, but the nostalgic feeling was not neglected either: with the Sega Mega Drive, the Sega Master System (SMS) and the Nintendo Entertainment System (NES), gamers were able to travel back in time.

But what would a Fab Lab Game Night be without the right music? DJs Pyrenzo and Unicorn Crew created an electrifying atmosphere in the Fab Lab with their infectious beats and melodic sounds.

The party being in full swing

“We have 300 computers in the basement, do you want them?”

Of course we want them: 6-core i5 CPUs, M.2 SSDs and 8 GB DDR4 Ram are a good basis for an office or gaming computer. As you know, we have been getting more and more involved in STEM education since last year. So this calls for a cool format where we can dismantle computers, assemble them back together and then give them to participants for free. Thus, we were happy to accept the offer.

But how do we transport 300 computers to the Fab Lab? That’s not only 1,800 CPU cores, 2,400 GB Ram and 150,000 GB memory in total, but also 2.1t total weight…
The Lions Club Siegen and the SIEGENIA GROUP were kind enough to help us. “We do not have a truck available, but we will rent one for you.”, said Wieland Frank, owner of SIGENIA GROUP. Two employees also came to support. Thanks again!

Now we are planning a new workshop series that (hopefully) launches in October:

“Build your own computer” (just a working title, suggestions are welcome).

The idea: young participants take apart computers with us, we look at the components and how they work and then reassemble them together. Afterwards an operating system will be installed and at the end the participants can take the computers home.

We can use your support:

  • Helpers to support the workshop implementation,
  • 300 mice, keyboards and/or monitors (could be used, but should be working and clean)

Schools are welcome to contact us. We heard that a few computer rooms here and there could be renewed.

We would like to do some research on the workshop as part of our EnvironMINT project to analyze the conditions for success of good STEM education in more detail. How can workshops be designed in an appealing way – especially to get young women and girls interested in STEM topics?

History lesson on STEM activities of the Fab Lab
With FAB:MAKE, we were able to purchase hardware that allows us to carry out workshops with smaller groups. As part of EnvironMINT, we are investigating the conditions for success of good STEM education with our partners (FAU Erlangen-Nuremberg, HS Rhein-Waal). In cooperation with Digitalum Bus, we are able to bring the topics mainly to the more rural areas in the old district of Wittgenstein.

From time to time, school classes also visit us and we carry out project days. But that’s not quite enough for us. We would like to build a strong network in Siegen-Wittgenstein with actors in the region: Schools, associations, companies, MINT partners and many more.

A lot of strong partners are already involved: Fab Lab Siegen, Digitalum-Wittgenstein gGmbH, FRids e.V., DRK Kreisverband Siegen Wittgenstein e.V., Bildungszentrum Wittgenstein, Lions Club Siegen, companies such as SIEGENIA GROUP and Pollrich GmbH, but also some schools as well as the Siegerlandmuseum.

We hope that the network will continue to grow and are excited about what we will achieve together in the future!

Theorie, Schule oder doch lieber Fab Lab? Gelingensbedingungen guter MINT-Bildung

Anfang März sind wir im Rahmen des Projekts EnvironMINT (BMBF: Gelingensbedingungen guter MINT-Bildung) nach Kamp-Lintfort am Niederrhein gereist. Zusammen mit unseren Kollegen der Friedrich-Alexander-Universität Erlangen-Nürnberg und der Hochschule Rhein-Waal haben wir bei einer 3-tägigen Workshopreihe untersucht, was Kinder und Jugendliche zu Fab Labs hinzieht und was sie davon abhält. Die knapp 100 Kinder eines Gymnasiums vor Ort haben uns durch die Teilnahme bei Kreativ-Workshops, Fokusgruppen und Interviews dabei geholfen, ihren Alltag besser zu verstehen. Dabei haben wir sehr viel von den SchülerInnen gelernt.

Was interessiert die Kinder und Jugendlichen eigentlich? Wie sollten man Workshops gestalten, die Spaß machen und lehrreich sind? Was schreckt ab? Wie sieht der Alltag so aus?

Nach einer Führung durch das FabLab Kamp-Lintfort – Hochschule Rhein-Waal und einer kleinen IoT-Demonstration mit unseren Goodies durften sie selbst ran und ausprobieren. Dabei waren unter anderem ein selbstgedrucktes und -gebautes Mikroskop, ein ferngesteuerter Malroboter mit dem Calliope Mini, ein Synthesizer-Kit von littleBits und viele coole andere Sachen.

Wir werden im weiteren Verlauf auch mit LehrerInnen, MakerInnen und Eltern sprechen, um besser zu verstehen, wie coole MINT-Angebote aussehen sollen und was die Hürden für alle Beteiligten sind. Am Ende des Tages gestalten wir die Konzepte ja nicht für uns – sondern die Menschen die es betrifft.
