Additive Manufacturing of Drug Delivery Systems

New Drug Delivery Devices are produced using Selective Laser Micro Melting (SL mu M). In a first approach, hollow micro needles with an inner diameter of 160 mu m were manufactured from 316L stainless steel powder. Afterwards, the hollow micro needles were successfully filled with a test liquid. In a second approach, fully dense micro needles with an outer diameter of 200 mu m were produced. A femtosecond laser setup was used to create discrete drug depots in fully dense micro needles.
