Abstract

Micro-needles are known as a mean that can minimize pains while it gets through the human skin. And it will be safer if it can be made of biodegradable material. Microstereolithography (MSL) forms a part by the photo-polynerization of liquid resin. And it has production resolution in the range of several tens of micrometers. So it can be used to fabricate precise micro-needle. Actually the MSL technology is frequently applied to various areas such as bioengineering and MEMS devices. This paper shows the framework of a micro-stereolithography apparatus which can fabricate micro-needle by using multiple materials including photocurable biodegradable material like PPF (poly propylene fumarate). And will introduce process parameters for the precise micro-needle fabrication. Finally, verifies the system by showing some examples of the micro-needle with multiple materials including PPF.
