Apparatus and method for making three-dimensional articles using bursts of droplets |
摘要 |
An apparatus includes a processor for controlling a build material dispenser and a dispenser positioner to construct a three-dimensional article in successive layers based upon article defining data, and wherein the processor operates the dispenser to dispense a series of bursts of build material at a series of respective target positions as the dispenser is advanced along a predetermined path of travel. Each burst is defined by a plurality of droplets dispensed in relatively rapid succession so that the build material thereof combines at a respective target position. The build material dispenser is preferably a jet including a piezoelectric actuator for ejecting a droplet of build material responsive to a corresponding firing signal. Accordingly, the processor generates a predetermined number of firing signals for the piezoelectric actuator corresponding to a desired number of droplets in each burst. Method aspects of the invention are also disclosed.
