Journal ArticleDOI
Bone tissue engineering using polycaprolactone scaffolds fabricated via selective laser sintering.
J. M. Williams,Adebisi Adewunmi,Rachel M. Schek,Colleen L. Flanagan,Paul H. Krebsbach,Stephen E. Feinberg,Scott J. Hollister,Suman Das +7 more
TL;DR: The integration of scaffold computational design and free-form fabrication techniques presented here could prove highly useful for the construction of scaffolds that have anatomy specific exterior architecture derived from patient CT or MRI data and an interior porous architecturederived from computational design optimization.
PatentDOI
Direct selective laser sintering of metals
Suman Das,Joseph J. Beaman +1 more
TL;DR: In this paper, a method of fabricating a fully dense, three dimensional object by direct laser sintering is disclosed, in which a degased powder layer is dispensed over a target surface and a beam of directed energy melts metallic powder in order to form a solid layer cross section.
Journal ArticleDOI
Mechanical and microstructural properties of polycaprolactone scaffolds with one-dimensional, two-dimensional, and three-dimensional orthogonally oriented porous architectures produced by selective laser sintering.
Shaun Eshraghi,Suman Das +1 more
TL;DR: Finite element analysis showed good agreement between experimental and computed effective tensile and compressive moduli and the construction of bone tissue engineering scaffolds endowed with oriented porous architectures and with predictable mechanical properties through SLS is demonstrated.
Journal ArticleDOI
Physical Aspects of Process Control in Selective Laser Sintering of Metals
TL;DR: In this paper, a first step is taken towards identifying and understanding some of the important physical mechanisms in direct selective laser sintering (SLS) is discussed, including oxidation, non-equilibrium wetting, epitaxial solidification, metal vaporization, and oxide purification.
Journal ArticleDOI
Engineering craniofacial scaffolds
Scott J. Hollister,Chia-Ying Lin,Eiji Saito,R. D. Schek,Juan M. Taboas,J. M. Williams,Brock Partee,Colleen L. Flanagan,Alisha Diggs,E. N. Wilke,G.H. van Lenthe,Ralph Müller,Tobias Wirtz,Suman Das,S Feinberg,Paul H. Krebsbach +15 more
TL;DR: Integrated image-based design and solid free-form fabrication can create scaffolds that attain desired elasticity and permeability while fitting any 3D craniofacial defect, suggesting that designed scaffolds are clinically applicable for complex cranioFacial reconstruction.
