The two-dimension hollowing algorithm for rapid prototyping technology

摘要

The hollowing process plays an important role in some rapid prototyping technologies such as stereo lithography apparatus (SLA), fused deposition modelling (FDM) and select laser sintering (SLS). This paper introduces an efficient two-dimensional hollowing algorithm. The principles of algorithm and implementation are presented. In addition, a detailed analysis is used to study the effect of the scanning path and online character in the actual fabricating process.
