Algorithms for accurate rapid prototyping replication of cancellous bone voxel maps

G. Sisias, R. Phillips, C.A. Dobson, M.J. Fagan, C.M. Langton

A set of algorithms has been developed and evaluated for 3D and 21/2D rapid prototyping replication of 3D reconstructions of cancellous bone samples. The algorithms replicate a…

Bone structure models using stereolithography: a technical note

R. Bibb, G. Sisias

The development of a physical model of cancellous bone whose structure could be controlled would provide significant advantages over the study of in vitro samples, making…

Equidistant path generation for improving scanning efficiency in layered manufacturing

Y. Yang, H.T. Loh, J.Y.H. Fuh, Y.G. Wang

Path generation is an important factor that affects the quality and efficiency of most laminated manufacturing processes such as SLS, SLA and FDM. This paper introduces an…

Void eliminating toolpath for extrusion‐based multi‐material layered manufacturing

Dan Qiu, Noshir A. Langrana

For extrusion based multi‐material layered manufacturing (LM) processes, a CAD system has been developed which generates high quality toolpath for part fabrication. This closed…

3‐D photonic bandgap structures in the microwave regime by fused deposition of multimaterials

Mauricio E. Pilleux, Ahmad Safari, Mehdi Allahverdi, Youren Chen, Yicheng Lu, Mohsen A. Jafari

Three‐dimensional photonic bandgap (PBG) structures using alumina (Al₂O₃) as the high permittivity material were modeled and then the structures were fabricated by Fused…

Prosthetic sockets fabrication using rapid prototyping technology

P. Ng, P.S.V. Lee, J.C.H. Goh

The traditional way of making a prosthetic socket is by draping a heated thermoplastic sheet over the positive mould, or by applying layers of woven materials together with…
