An adaptive slicing algorithm based on stereo lithography (STL) model was proposed in order to improve the forming precision of product in rapid prototyping. In the algorithm, the topological information of STL
A carefully designed adaptive slicing algorithm for STL models can be found in Ref. [5]. Cormier et al. [6] and Mani et al. [7] also used a region-based variable tolerance for adaptive slicing. All these approaches are based on an STL interface, the de facto standard of the RP ...
Section 2 presents the decomposition of the CAD model into regions and the layer thickness determination for each region. The algorithm for the region-based adaptive slicing scheme is described in Section 3. We present implemented examples in Section 4 and in Section 5 we remark on the ...
This study aims to develop a novel adaptive slicing method based on ameliorative area ratio and accurate cusp height for 3D printing using stereolithography (STL) models. Design/methodology/approach The proposed method consists of two stages. In the first stage, the STL model is sliced with ...
