快速成型(RP)技術有哪些特點

2011-07-07 關注次數:
快速成型(RP)技術將一個實體的復雜的三維加工離散成一系列層片的加工,大大降低了加工難度,具有如下特點:  
 
(1)成型全過程的快速性,適合現代激烈的產品市場;  
 
(2)可以制造任意復雜形狀的三維實體;
  
(3)用CAD模型直接驅動,實現設計與制造高度一體化,其直觀性和易改性為產品的不錯設計提供了優良的設計環境;
  
(4)成型過程無需專用夾具、模具、刀具,既節省了費用,又縮短了制作周期。
  
(5)技術的高度集成性,既是現代科學技術發展的必然產物,也是對它們的綜合應用,帶有鮮明的技術特征。   
以上特點決定了RP技術主要適合于新產品開發,快速單件及小批量零件制造,復雜形狀零件的制造,模具與模型設計與制造,也適合于難加工材料的制造,外形設計檢查,裝配檢驗和快速反求工程等。
