Stuttgart, Deutschland Fraunhofer-Gesellschaft Vollzeit

**_Thesis | Find the limits of an inkjet print head - formulation of test inks and determination of optimal process parameters_**

In cooperation with the print head manufacturer Seiko Instruments, we want to explore the limits of one of their print heads:
The motivation: Shorten the process development - Give fast statement whether and with which parameter set a process development can be started. Use just a mínimal set of rheological measurement data/properties of an ink for this. A set of initial, well defined set of basic inks is needed for this.

We are looking for your support in this field

**What you will do**

Develop a set of basic inks that covers the desired property spectra of typical inks including the rheological characterisation afterwards.
- Selection, formulation, and characterisation of components for base inks (viscosity | surface tension | visco-elastic properties | particle size |...).
- Determine optimal printing parameters for these base inks by means of drop-watching (waveform | voltage | frequency | temperature |..)

**What you bring to the table**
- Basic knowledge in the field of rheology
- Basic knowledge in the field of (polymer) chemistry
- Basic knowledge of digital printing
- Experience in designing, carrying out and evaluating experiments
- Independent and creative working style
- Careful and structured way of working
- Languages: German & English
- Thesis language: English

**What you can expect**

The work supervision is to be done in close cooperation with Seiko Instruments, for this also test days at Seiko Instruments on site are planned.

If you have experience in polymer chemistry and rheology, this would be an advantage. You are expected to work on the topic in a structured, careful and independent manner. At the same time, employees from the specialist departments will always be available to help you with in-depth questions and problems.

With its focus on developing key technologies that are vital for the future and enabling the commercial utilization of this work by business and industry, Fraunhofer plays a central role in the innovation process. As a pioneer and catalyst for groundbreaking developments and scientific excellence, Fraunhofer helps shape society now and in the future.
