Adaptive layer approximation of free‐form models using marching point surface error calculation for rapid prototyping

Bahattin Koc

A new surface error calculation method for layered manufacturing processes is proposed in this paper. The developed method is used to generate the layers by adaptively varying the…

Manufacturing sacrificial patterns for casting by salt powder lamination

Yoji Marutani, Takayuki Kamitani

The increasing use of rapid prototyping (RP) which fabricates complicated models easily, has highlighted the desire for making metal models also with RP technology. However…

CAD model decomposition for WirePATHTM

James Brink, Alex Lee, David Anderson, Karthik Ramani

This paper describes algorithms and software for decomposing CAD models for a new mold manufacturing process called WirePATH™, which uses wire electrical discharge machining (EDM…

Process build‐time estimator algorithm for laminated object manufacturing

John Kechagias, Stergios Maropoulos, Stefanos Karagiannis

A method for estimating the build‐time required by the laminated object manufacturing (LOM) process is presented in this paper. The proposed algorithm – taking into account the…

Effects of electroplating on the mechanical properties of stereolithography and laser sintered parts

N. Saleh, N. Hopkinson, R.J.M. Hague, S. Wise

This paper provides a quantitative and qualitative assessment of the effects of electroplating on polymer parts made by stereolithography (SL) and laser sintering. A series of…

A processing algorithm for freeform fabrication of heterogeneous structures

Wei Sun, Tao Jiang, Feng Lin

A processing algorithm for freeform fabrication of heterogeneous structures is presented. The algorithm was developed based on the heterogeneous fabrication structural model…

Fabrication of artificial bioactive bone using rapid prototyping

Zhongzhong Chen, Dichen Li, Bingheng Lu, Yiping Tang, Minglin Sun, Zhen Wang

A new technique based on rapid prototyping (RP) is proposed to fabricate the mould of artificial bone composed of a nontoxic soluble material. The mould has both an external…
