Hybrid 3D printing technique produces liquid-filled objects

Harald Rupp Ordinarily, if you want to make a 3D-printed liquid-filled object, you have to inject the liquid after the object has been printed. A new process, however, allows such items to be printed all in one step – and the technology could have some valuable applications. The technique was developed by a team at Germany s Martin Luther University Halle-Wittenberg, led by Prof. Wolfgang Binder and researcher Harald Rupp. It utilizes a unique system that incorporates two 3D printing heads – one builds objects up by extruding successive layers of molten polymer, while the other (an inkjet print head) deposits tiny droplets of liquid.

 E-Mail Credit: Harald Rupp / Uni Halle Chemists at Martin Luther University Halle-Wittenberg (MLU) have developed a way to integrate liquids directly into materials during the 3D printing process. This allows, for example, active medical agents to be incorporated into pharmaceutical products or luminous liquids to be integrated into materials, which allow monitoring of damage. The study was published in Advanced Materials Technologies . 3D printing is now widely used for a range of applications. Generally, however, the method is limited to materials which are liquefied through heat and become solid after printing. If the finished product is to contain liquid components, these are usually added afterwards. This is time-consuming and costly. The future lies in more complex methods that combine several production steps, says Professor Wolfgang Binder from the Institute of Chemistry at MLU. That is why we were looking for a way to integrate liquids directly into the material d
