| Research Abstract |
A laser sintering apparatus equipped with an optic system that can focus its beam in a spot one third diameter as small as typical commercially available. As a result, a vertical wall of 180μm in thickness and a slit of 300μm in gap were successfully built. Relationship between the beam diameter and fineness of obtained structure is investigated. The minimum wall thickness that maintains sufficient mechanical strength was obtained as 0. 6mm. To improve the resolution of tissue engineering scaffold, plastic sacrificial filler was tested.
