  1. But the standard mc has some shortcomings : firstly, the standard mc picks up isosurfaces by threshold, however, threshold segmentation is invalid for picking up tissues or organs from some medical images ; secondly, the standard mc pocesses cubes one by one, that is to say, all the cubes will be checked, and the algorithm spents 30 % - 70 % of time to check the null units, so we need a reasonable data structure to travel the space data and accelerate the checking or filting of null units ; thirdly, the standard mc has a large scale of triangles, normally, the tissue or organ reconstructed includes hundreds of thousands so much as millions of triangles, this means it hardly to execute real - time rendering or interaction ; lastly, the standard mc can not get the very smoothly surface mesh, and there will be some unexpected accidented cases, especially in the case of big errors in oringinal data

    但是mc演算法存在較大的問題:mc演算法實質上是通過閾值分割來提取等值面,閾值分割對某些醫學圖像的組織或器官的提取難以得到較好的效果;mc演算法是逐個移動立方體來進行處理,就是說對所有的立方體都要進行一次檢,演算法執行中30 % ~ 70 %的時間用在對空單元的檢上,因此需要有一合理的數據結構對空間數據進行有效的遍歷,以加速對空單元的檢和過濾;mc演算法產生了大量的三角面片,一般重建的組織或器官包含數十萬甚至上百萬的三角面片,難以實現實時的繪制和互操作;mc演算法得到的表面網格並不光滑,會有一些不期望的凹凸,特別是在始數據有較大誤差的情況下尤其突出。
  2. The main process parameters influencing fdm prototype quality are determined. by taguchi experiment, various features data of the 27 prototyped standard test part are measured and treated, the effects of fdm process parameters on the quality of prototype are investigated, and fdm process parameters are optimized, thus, a set of fdm prototyping process rules based on parameter optimization is presented

    針對fdm快速成型工藝,確定出影響型件質量的主要工藝參數,通過正試驗,對加工出的27個試件的各特徵進行量與數據處理,研究了fdm工藝參數對型件質量的影響規律,進而優化fdm工藝參數,並形成了一套完整的基於參數優化設置的fdm成型工藝規程。
