Circuit printers: Voltera and Voxel8

Back in 2009 at a conference (ISMRM) I saw a talk where a group “printed” radio frequency probes (essentially tuned magnetic field loop antennas) for MRI using a silver based ink in a very expensive inkjet printer. Once printed the substrate (FR4, kapton, PTFE for example) was baked in an oven which solidified the ink into a contiguous conductive surface. The results looked good, the probes performed as well as a regular copper trace coil, where low resistance is crucial. However this baking process was important. Unless a high temperature 3d printing material is available then this will not be possible, and these printed electronics will be only possible for very basic circuits where low resistance lines are not necessary. Maybe they have cracked it though, but I’ll believe it when my multimeter sees it. Also a hacker friendly circuit needs to be able to withstand re-sold...
