The rapid tooling testbed: a distributed design‐for‐manufacturing system

David W. Rosen, Yong Chen, Shiva Sambu, Janet K. Allen, Farrokh Mistree

A new design‐for‐manufacturing method, called the geometric tailoring (GT), and the associated digital interface concept have been developed that enable the design activities to…

A 3D surface offset method for STL‐format models

Xiuzhi Qu, Brent Stucker

This paper presents a new 3D offset method for modifying CAD model data in the STL format. In this method, vertices, instead of facets, are offset. The magnitude and direction of…

Biomaterial forming research using RP technology

Yongnian Yan, Rendong Wu, Renji Zhang, Zhuo Xiong, Feng Lin

This paper introduces a new subject called bio‐manufacturing. Bio‐manufacturing combines life science with manufacturing science, and uses manufacturing method to form materials…

Stereo‐thermal‐lithography: a new principle for rapid prototyping

P.J. Bartolo, G. Mitchell

A new fabrication process for rapid prototyping is proposed in this paper. Optical and thermal effects are simultaneously used in this process to locally induce a phase change in…

Improved surface finish in 3D printing using bimodal powder distribution

Michele Lanzetta, Emanuel Sachs

The use of bimodal powders has been shown to offer the possibility of dramatically improved surface finish in 3D printing. This work focused on individual lines, the primitive…

The customized mandible substitute based on rapid prototyping

Liu Yaxiong, Li Dichen, Lu Bingheng, He Sanhu, Li Gang

Traditional standard bone substitutes cannot realize the individualized matching for the bones of different patients. In order to make a bone substitute match the shape of a…

Design for medical rapid prototyping of cranioplasty implants

L.C. Hieu, E. Bohez, J. Vander Sloten, H.N. Phien, E. Vatcharaporn, P.H. Binh, P.V. An, P. Oris

Design methods for medical rapid prototyping (RP) of personalized cranioplasty implants are presented in this paper. These methods are applicable to model cranioplasty implants…
