    • A process and apparatus for free form fabrication of a three-dimensional work piece comprising (a) feeding raw materia! in a sold state to a first predetermined location; (b) depositing the raw material onto a substrate as a molten poof deposit under a first processing condition; (c) monitoring the molten pool deposit for a preselected condition; (ύ) comparing information about the preselected condition of the monitored molten pooi deposit with a predetermined desired value for the preselected condition of the monitored molten poo! deposit; (e) solidifying the molten poo! deposit; (f) automatically altering the first processing condition to a different processing condition based upon information obtained from the comparing step (d); and repeating steps (a) through (f) at one or more second locations for building up layer by layer a three-dimensional work piece. The apparatus is characterized by a detector that monitors a preselected condition of the deposited material and a closed loop electronic control device for controlling operation of one or more components of the apparatus in response to a detected condition by the detector.
    • 一种用于自由形成三维工件的方法和装置,包括(a)原材料的供给! 处于销售状态到第一预定位置; (b)在第一处理条件下将原料沉积在基底上作为熔融沉积物; (c)监测熔池沉积物的预选条件; (?)将关于所监测的熔融沉积物的预选条件的信息与所监测的熔融气泡的预选条件的预定期望值进行比较! 存款; (e)凝固熔融的poo! 存款; (f)基于从比较步骤(d)获得的信息,自动地将第一处理条件改变到不同的处理条件; 以及在一个或多个第二位置重复步骤(a)至(f),以逐层建立三维工件。 该装置的特征在于监测沉积材料的预选状态的检测器和用于响应于检测器检测到的条件来控制装置的一个或多个部件的操作的闭环电子控制装置。
