3D Printing in Crisis Operations

The novel coronavirus severely limits societies and puts us all to the test. Over the past weeks, strong solidarity between people and initiatives could be observed in Germany and around the world. In this country, the “Maker vs. Virus” network has formed virtually overnight. Thousands of people organize there to produce makeshift equipment to solve various problems: Face visors, ear protectors for mouth-nose masks, and much more. There is communication, collaboration, data exchange, printing, laser cutting, sewing and experimentation. Even the industry is advised. This discourse is very multifaceted and there are many topics that can be addressed: How exactly does the organization and coordination of such loose structures/initiatives work? What happens there interpersonally? 3D printers are not very efficient for mass production, but very helpful when it comes to fast, agile response. The Fab Lab itself produces face visors – but we see this only as a first aid until the demand for certified equipment can be met on the market. Injection molding plants have to “start up” first, production facilities and products have to be certified – that takes time. Meanwhile, tech-savvy people are providing equipment to doctors, schools and clinics. But there were also other innovations: Ventilators based on CPAP ventilators, splitter valves for ventilating several people with one machine emerged very quickly.

The aim is to obtain an overview of technological innovations in the field of digital fabrication or to examine individual innovations in more detail. Work in this area has a pure research focus.

Large Format 3D Printing with a Collaborative Robotic Arm

Additive manufacturing enables the production of parts that are not possible with more widely used subtractive processes such as machining. 3D printers can also be used to produce haptic and evaluable prototypes quickly and cost-effectively. Costly setup and tooling costs that would be incurred with processes such as machining or injection molding can be avoided. The initial cost of 3D printers has plummeted and the technology is affordable, but the working ranges of such machines are limited. Therefore, an industrial robot from Universal Robotics (model: UR10e) is to be converted into a large-format printer. The core of this work is to build a 3D printer, think about the design for making a large format printer and evaluate the usability of such a system.

Core activities could be: programming with RoboDK, Polyscope, Python, 3D modeling, IoT, and many more.

Data Visualization: Infrastructures of Cooperation

Everyone is talking about Industry 4.0, and many are talking about the benefits of digitization. In the context of distributed laboratories and workplaces, the question arises as to how collaboration between people and machines can be supported. What data needs to be collected and evaluated? What are the specific requirements of the users? Can maintenance be automated? How can interdisciplinary communication (engineer vs. designer vs. ….) be promoted? How can collaboration be enabled? Core activities may include either a technical or research focus:

Programming in Python (Django), C, Front-End-Development, IoT, HTML5/CSS/JS, MqTT, Zigbee. General hacking of existing 3D printers in the Fab Lab.

An ethnographic and participatory research approach can be applied to find design implications and conceptualize a system.

Development and Evaluation of a Fab Lab Management Systems

A Fab Lab is an open workshop with machines that can be dangerous if used improperly. An open workshop means that a large number of people with different backgrounds and levels of knowledge can work on different machines and work areas. Occupational safety and health are important to protect users and machines. Users must be instructed in the various work areas in order to use them. But how can you ensure that users only work on machines for which they have been instructed?

The devices must be maintained at regular intervals – predictive maintance is a buzzword here. IoT and advanced technologies can enable machines to communicate and exchange data. To explore how an infrastructure that makes workshops (such as fab labs, makerspaces, hackerspaces, etc.) “smart” might look.

Core activities may include either a technical or a research focus:

Programming in Python (Django), C, Front-End-Development, IoT, HTML5/CSS/JS, MqTT, Zigbee.

An ethnographic and participatory research approach can be applied to find design implications and conceptualize a system.

Robotics: Human Machine Interface (HMI) for Controlling a Robot

Collaborative robots have found their way into industry and manufacturing. They are designed to work with people and are advertised as being easy to program and use. The machines can be programmed through direct physical human interaction. They can also be programmed on the screen via an IDE. But how intuitive is the handling of the robot? Can the interaction be done in a more natural way? What role can AR and VR applications play?

The core of the work is to directly control and program an industrial robot via an AR/VR application.

Smart City: Open Network – Open Data with LoRaWAN

The Low Range Wide Area Network (LoRaWAN) enables the transmission of small amounts of data over relatively long distances. It also enables, for example, battery or solar-powered systems to be operated in a regional, national or even global network. LoRaWAN it thus enables the Internet of Things in almost any place – due to the high range – even where there is no Internet coverage. The relatively open design of the standard results in a wealth of application examples and areas. The aim of this work is to conduct initial studies on the basis of self-developed projects, prototypes, which can serve as a basis for a larger pilot project within the framework of Smart City. The network and the data should be open for use by: Citizen groups, individuals, schools, industry, universities, cities, etc.

Additive Manufacturing: Sustainability, Waste & Reclycing

Part labelling through automated GCode modification during slicing.

3D printing has become very popular over the past decade. Expiring patents have enable a strong push in innovation around this topic, leading to a plethora of open-source machines (cf. While enthusiasts have opened up the floor for wider audience, a few businesses took up the idea and created out-of-the-box usable machines, enabling a wider spread adoption of the technology in businesses but also homes.
Those machines use different polymers to produce parts. Users buy materials ranging from ABS, PET, PLA to photopolymer resins to use in their machines at home. With a growing community, misprints and other waste is produced as well. How can reclycling 3D printed plastics be supported? Usually platics are labeled with a specific identifer, so they can be properly recycled (cf.

Recycling codes on consumer products and packaging.

However, 3D printed objects are not labeled and therefore cannot be led into recycling cycles at the end of their lifetime.
There has been some research in the past on labeling 3D printed parts during the print preparation process (i.e. within a slicer), however the proposed solution is not very usable and requires a high amount of technological expertise.

This research should evaluate a modular option in popular slicers (PrusaSlicer, Cura) that enables automated process to label printed parts and the acceptability by users.

Sustainability and Environmental Awareness in Desktop SLA Printing

Tags: user-research ethnography participatory-action-research field-research

Stereolithography printing (SLA) is getting more attention, especially as machines and materials have become more affordable for consumers and business. SLA printers offer a great surface finish on objects and high degree of detail.

The SLA workflow is however not as trivial as the wider spread FDM workflow. The material is liquid, sticky and dangerous to humans, animals and especially the aquatic environment. Moreover, objects printed need post-processing: they have be washed and cured with UV light. This leaves users with byproducts containing solved resin, which needs special means of disposal.

This research should investigate the SLA workflow in desktop SLA printing of home users. A study should be performed in various online communities. This includes how awareness is raised on the dangers and how users implement the workflow at home or in businesses. Interviews with users should be conducted.
