Embodiment Construction

[0016] For a general understanding of the context of the devices disclosed herein, as well as details of the devices, reference is made to the accompanying drawings. In the drawings, like reference numerals denote like elements.

[0017] figure 1 The arrangement of components in the printer 100 that produces the three-dimensional object part 10 is shown. Printer 100 includes support material container 14 , build material container 18 , a pair of inkjet printheads 22 , 26 , build substrate 30 , planar support member 34 , columnar support member 38 , actuator 42 , and controller 46 . Tubing 50 connects printhead 22 to support material container 14 and tubing 54 connects printer 26 to build material container 18 . The two inkjet printheads are operated by the controller 46 with reference to the three-dimensional image data in memory operatively connected to the controller to eject the support and build material supplied to each respective printhead. When building the part, the...

Abstract

A printer uses closed loop control to keep material drops ejected by a printhead within a predetermined range. The printer forms at least two objects on a support member and then operates a specular sensor array to obtain image data of the two objects on the support member. The two objects have different predetermined heights to enable a controller in the printer to identify the mass or volume of the material drops forming the objects to adjust operational parameters of the printer to maintain the mass or volume of the material drops in the predetermined range.

Description

technical field [0001] The apparatus disclosed herein relates to printers that produce three-dimensional objects, and more particularly to accurate detection of the mass of a drop of material used to produce three-dimensional objects in such a printer. Background technique [0002] Digital 3D manufacturing, also known as digital additive manufacturing, is the process of manufacturing three-dimensional solid objects of virtually any shape from digital models. 3D printing is an additive process in which successive layers of material are formed in different shapes on a substrate. Three-dimensional printing is distinguishable from traditional object forming techniques, such as cutting or drilling, which rely primarily on removing material from a workpiece through a subtractive process. [0003] Some printers that produce three-dimensional objects use a flat platform area onto which one or more printheads eject ink droplets that build layers of material to form the object. The ...
