Revolution in 3D printing: Bochum start-up brings micro-laser technology!

The need for precise components is growing rapidly in various industries, particularly in electrical engineering and medical technology. In view of these increasing requirements, a team at the Ruhr University Bochum is developing an innovative system for micro 3D printers based on a diode laser. This new solution could revolutionize the way microstructures are manufactured. According to the information from news.rub.de is the PicoShape development team, consisting of Dr. Nils Surkamp, ​​Felix Behlau, Dr. Benedikt Hofmeister and Jasper Helle, ready to bring the technology to market.

Micro 3D printing has the ability to create three-dimensional structures in the micrometer range. The PicoShape system uses two-photon polymerization (2PP), a process that enables a resolution of less than 100 nanometers. This technology is not only precise but also efficient. Diode lasers are smaller and more energy efficient than traditional lasers, which promotes a faster printing process. Given the high cost of conventional micro 3D printers, which cost at least half a million euros, PicoShape represents a flexible and more cost-effective alternative.

Technological innovations in tune with the times

The development of 2PP technology is the result of 15 years of fundamental research at the University of Grenoble Alpes. The first scientific publications about the method date back to 2002, and it has since established itself as a key technology for 3D printing in the micro and nano ranges. Loud microlight3d.com Highly reproducible voxels can be created through precise manipulation of laser pulses and nonlinear laser-polymer interaction. These are crucial for producing high-resolution 3D objects.

In two-photon polymerization, the resin hardens through the simultaneous absorption of two photons. This enables the production of complex structures in the micro and nanometer range. This technology is particularly groundbreaking in application areas such as micro-optics, micromechanics and medical applications, for example for scaffolding structures for cell growth or implants.

Support and perspectives

As part of the EXIST funding, PicoShape received around 1.1 million euros from the Federal Ministry of Economics and Climate Protection to develop a marketable product and build a sustainable business model. The funding began on April 1, 2025 and includes individual coaching and access to a support network. The support from the WORLDFACTORY at the Ruhr University Bochum plays a crucial role in this.

The team focuses on developing prototypes and providing feedback from practice. Other planned measures include increasing visibility through public appearances and collaborations to open up sales opportunities and offer a printing service that facilitates access to the technology. This innovative strength was also recognized by PicoShape being named one of the top three startups at the Ruhr University last year.

In an increasingly competitive market, it is crucial for companies to stand out through innovative technologies. The advances made possible by the combination of diode laser technology and 2PP show the great potential of micro 3D printing, especially in the production of highly specialized and complex components.
