Abstract

ASTM Task Force F04.42.06 was formed with the objective of developing reference scaffolds, with the initial thrust focused on porosity.Three dimensional test-scaffolds were fabricated by two 3-Dimensional rapid prototyping methods. Visual examinations and micro-Computerized-Tomography (micro-CT) showed cubic scaffolds with 300 m pores having a lack of uniformity and numerous defects that consisted of either large empty spaces or occluded connections whereas cubic scaffolds with 600 m pores were moremm uniform. Both methods appear to be capable of producing useful scaffolds for evaluation of measurement technologies for porosity determinations prior to fabrication of reference scaffolds. X-ray micro-CT appears indispensable for revealing details of internal structure. Scaffolds from rapid prototyping systems need careful assessments to ensure integrity.
