Either fast or precise – both are not possible in the production of the finest polymer structures with lasers. Or is it?
The combination of stereolithography and multiphoton polymerization should make it possible: Scientists at the Fraunhofer Institute for Laser Technology ILT are developing a machine for high-precision, economical 3D assembly techniques that uses both methods.
On November 1, 2018, the project partners ILT Fraunhofer, Bartels Mikrotechnik GmbH, Miltenyi Biotec and LightFab GmbH launched the project “High productivity and attention to detail in additive manufacturing through the combination of UV polymerization and multiphoton polymerization – HoPro-3D”, which is funded by the European Union and the state of North Rhine-Westphalia.
Cardiovascular diseases are the leading cause of death in industrialised countries today.
The most important indicator of the health status of this system is blood pressure. If it is too high, countermeasures are necessary to prevent possible damage to health.
Today, it is not possible to measure blood pressure continuously in the home environment. With today’s methods, 24-hour monitoring is a great burden for patients, as it consists of individual measurements at regular intervals, distributed over day and night.
The aim of the project is to develop a microsystem including the necessary sensor-actuator components for permanent, non-invasive blood pressure monitoring in the ear.
The aim of the SeQuLas project is to develop a novel process technology for the absorber-free laser welding of thermoplastics.
In this case, not only the segmentation of the seam contour should be done by means of a continuously updating temperature field during the welding process.
The irradiation order and parameters should also be adapted in order to ultimately realise a defined energy input. SeQuLas intends to increase the flexibility and efficiency of industrial production in NRW.

Space missions are extremely expensive high-tech projects where the technology has to ensure maximum reliability. If a component fails in space, tens of millions are lost, sometimes this is in the billions.
Also for this reason, the student small satellite group of the University of Stuttgart e.V. (KSat) has worked on a practice project with a maintenance-friendly Bartel pump, which operates without mechanical parts: the mp6.
This micro-pump will now make its way to the ISS where it will pump a ferrofluidic fluid to test a NASA experiment for an alternative rocket propulsion in weightlessness.
