Dr. Wojciech Jastrzebski named finalist for 2023 Hackaday Prize

Dr. Wojciech Jastrzebski named finalist for 2023 Hackaday Prize

We are pleased to announce that Dr. Wojciech Jastrzębski from SWPS University’s Faculty of Law and Communication in Wrocław has received a prestigious award in the Hackaday Prize 2023 competition for his revolutionary project enabling a new printing technique using photosensitive ink.

The next generation of print

Dr. Wojciech Jastrzębski's project was submitted in the "Gearing Up" category, in which participants showcased projects aimed at improving workshop and manufacturing techniques with new tools. His project stood out as one of the ten awarded entries that advanced to the finals.

The list of finalists

Originally, this tool was intended for printing masks used in the process of etching electronic circuit boards, which involves removing unwanted metal components from their surfaces. Surprisingly, this printing technique can be successfully applied to various materials that do not absorb liquids, such as metal, ceramics, and plastics. Furthermore, it enables printing on curved or irregular surfaces as the image is projected without direct contact with the object.

At the current stage of the project, there is already a prototype that includes a 3D printed case with a magnetic frame that can be covered with a transparent film. Inside there is an LED that glows with ultraviolet light, along with a cooling system. There is also a concept for a more advanced form of the device, with the ability to project graphics directly from the LCD screen.

It all started with experiments involving UV-cured ink, commonly used in services for repairing the protective coating of electronic circuit boards. What I found appealing was the ability to apply the ink directly to an object, selectively expose it to UV light, and then wash away the unexposed excess without the need for any specialized chemicals. There is no need for screens or stencils. The only thing you need to prepare is a printed pattern on a film.
