A 3D‑printed glucose biosensor for use in wearable monitors has been created by Washington State University researchers. The researchers used a method called direct-ink-writing (DIW), that involves printing “inks” out of nozzles to create intricate and precise designs at tiny scales. 3D printing can enable manufacturing of biosensors tailored specifically to individual patients.
Because the 3D printing uses only the amount of material needed, there is also less waste in the process than traditional manufacturing methods. This can potentially bring down the cost.
