Additive manufacturing has the ability to layer itself with a multitude of different technologies – one mode of developing an intelligent product is to imbed the technology onto the surface. In this project, developed in close collaboration with VTT (Technical Research Centre of Finland), ADD was presented with three different printing technologies that vary in industrial application and testing. The first was a plasma gun attached to the end of a robotic arm that prints conductive material – in this case copper. The second, a smaller and more precise printing technology, uses a syringe printhead at the end of a robotic arm to apply insulating or silver material. The third is and the most industrial, a UV ink-jet printing tool at the end of a robotic arm.

To understand how the three different printing technologies in this case work, the technologies were tested with a catalogue of substrate materials.

A catalogue of substrate materials was developed to test possible and viable application technologies – the materials tested were laser-sintered nylon, alumide, gypsum based powder, abs, paper and ceramic. Each surface had its own distinct “pattern” generated from an agent-based script. The variability of the patterns coupled with the material quickly revealed the limitation of each technology when honing the tool path. The second phase of the project is in process.
