21 Sep prototype drop analyzer
The development of ideas, visions and strategies is an integral part of our Think Tank. The picture above of a three-dimensional Lego model is not the result of the LEGO® SERIOUS PLAY® innovation method. It is however, the development and test environment of our peptech drop analyzer. We characterize with it our Flexink in terms of printability. Primarily the main focus of the experimental platform is the tear-off behavior and threading of a falling drop of ink from the needle. In addition, an integrated high-speed camera documents the process with a resolution of up to 1000 FPS.
As a result we are able to gain from the data for our further research and development conclusions on viscosity and internal, elastic structures of the ink, interactions between the ingredients of the recipe and even properties of the usedpolymeric binder. In the future, our aim is to also reduce the surface tension of our inks using the method of the hanging drop and the surface tension of the substrate according to the method of the lying drop. That way the wetting of the substrate by ink can be observed and measured directly.
