Abstract

This research realized 3D constructs by integrating more than one material with multi fabrication system within a single session. A commercial rapid prototyping system, RepRap MendelTM, is modified so that it enables us to realize microenvironment composed of multi materials namely gelatin hydrogel and polylactic acid. Firstly, the session is preceded by realization of 3D scaffold using polylactic acid (PLA) with porosity and modulus elasticity as characterized. Later, the gelatin extrusion took place to seed the cellular in determined spatial arrangement. The results show that our apparatus able to realized scaffold that using PLA as matrix filled with gelatin that act as cell carrier in future application. The scaffolds have porous around 0.25 mm2 porosity with a modulus of elasticity around 160 MPa.
