More robust, more efficient and more sustainable - that is our mission with the development, production and application of components in plastic and fibre composite technology. How can we support you on the way to innovative products?
We at the Technology Campus Hutthurm of DIT see ourselves as a research service provider for innovative solutions in plastics technology. In association with the Technology and Study Center Weissenburg, we represent the approach "Resource efficiency through process development, lightweight construction and materials research" at the Kunststoffcampus Bayern (kunststoffcampus-bayern.de).
Simulation is the attempt to capture and recreate reality, i.e. to find the right models as a reflection of it. The core is the identification of the relevant physical phenomena, their description with corresponding mathematical formulas, which are usually solved numerically in order to gain new insights into a given technical system or to invent new systems.
Our 3D scanner is equipped with two lenses and can optically recognise finest structures by capturing 16 million measuring points. By generating a three-dimensional view, comparative measurements and wall thickness measurements can be performed.
With our fully automatic and highly precise horizontal single-sample dilatometer, a sample can be measured over a temperature range from -90°C to 450°C in a defined atmosphere. The results from the temperature-dependent dimensional changes can be used for quality assurance and basic research for process simulation.
Dynamic mechanical analysis (DMA) can be used to assess the mechanical properties of materials as a function of temperature, time or humidity. By measuring the elastic and viscous properties, complex materials such as polymers and composites can be described for process simulation and, for example, the glass transition temperature of polymers can be determined.
DSC (Differential Scanning Calorimetry) is used to determine the amount of heat generated or released by a sample during heating or cooling. This enables the determination of characteristic material values (e.g. phase transitions, specific hear capacity), especially for filled and unfilled polymers, technical high-performance polymers and fibre-reinforced plastics according to DIN EN ISO 11357-1 to -7. These determined results form the basis for process simulations.
The rheometer is used to investigate material-specific deformation and flow behaviour and serves as a basis for process simulation. Flow tests, time-dependent measurements to determine creep behaviour and stress relaxation, but also vibration tests can be carried out. The viscosity and yield point are determined in order to gain a better understanding of the processability of plastics.
The Dynamic Materials Testing Machine is used to determine characteristic material values, in particular of filled and unfilled polymers and technical high-performance polymers as well as fibre composite plastics. These obtained values are required both as a basis for construction and design tasks (e.g. of lightweight structures and generally as input for simulations) and for the relative evaluation of different materials in the context of material selection.
Our 3D printer uses the Fused Filament Fabrication (FFF) process. Through integration of sensor technology during the printing process, the functionalisation of 3D printed components can be advanced. Thus, it is possible to derive material-process-property relationships in order to increase the overall performance of additively manufactured components.
Simulation is the tool of choice for designing tools for plastic injection moulding "first right", for example. Here, the mold filling with various materials and under variable process conditions can be evaluated in advance in order to robustly and economically realize the desired product. This saves expensive trials and the production of prototype tools. It also supports the search for innovative solutions for tool design and process control.
Wherever masses have to be moved, energy is consumed - this is where the lightweight construction aspect comes into play. Weight reduction can be achieved through alternative construction methods such as sandwich, ribs or bionic structures as well as the use of high-performance materials such as carbon fiber composites or a combination of these. In addition, completely new fields of application are possible, for example in the combination of fibre composites with metals.
In order to make manufacturing processes more transparent and robust, data acquisition systems and automated evaluation methods are increasingly being used. The latter require large amounts of data in order to "get to know" the process status and draw conclusions. Our goal is to use simulation to make manufacturing processes more robust and achieve zero rejects. To this end, data from virtual processing, for example, can be used as a basis for data analysis even before the first real component has been manufactured.
Equally great challenge and responsibility is the further use and reuse of plastic products at the end of their life cycle: recycling. We participate in the initiation of joint projects to make the processing of plastic waste more efficient and return it to valuable, technically sophisticated products.
The clever combination of process simulation and data analysis offers completely new possibilities for increasing the efficiency of manufacturing processes for plastic products. For example, ongoing activities are aimed at reducing the reject rate for 3D printed high-performance structures from 50% to 5% by using process simulation and artificial intelligence methods.
We are working on initiating projects to create a holistic understanding of materials, processes and structures in production and operation - the keyword being "digital twin". In connection with the digitalization of production, material flow simulation is another essential component for planning and ensuring stable and efficient production processes.

We offer students of the Deggendorf Institute of Technology to do research for their final thesis at the Technology Campus Hutthurm and to work on it within the scope of a project. In addition, advertised bachelor and master theses can also be carried out as internships.
You are also welcome to contact us if you are still looking for a company in the region for your industrial internship in the field of plastics technology.
No matter what topic you are interested in - scientific staff is at your disposal.
Current openings (in German):
With the still valid hygiene measures in place, but a lot of motivation, the first lecture at the Technology Campus in Hutthurm started on Monday, June 8, 2020.
As a university of applied sciences, DIT's research work is always rooted in real-life cases. Since 2009, DIT has successively established 11 Technology Campuses in the neighbouring districts around Deggendorf where staff and students develop innovative solutions or products. All projects have the financial backing of businesses who aim to immediately integrate research results into their company structures or production lines to improve their products or manufacturing efficiency.
Nine students from different universities were able to attend the lecture of the scientific campus director Prof. Dr. Mathias Hartmann. With sufficient safety distance and hygiene measures in place, nothing stood in the way of the long-awaited attendance event.
The Technology Campus (TC) Hutthurm focuses on innovative solutions in plastics technologies and establishes efficiency through process development, lightweight construction and materials research.
The whole team at the TC is happy that the event could take place despite the current situation.
Wir starten mit dem erweiterten Team und sind für Sie mit neuer Schlagkraft in allen Fragen rund um die Themen Simulation, Leichtbau und Nachhaltigkeit in der Kunststofftechnik da.
