Three-Dimensional Printing System with Multi-Fluid Servicing Module

A method of manufacturing a three-dimensional object comprising:

• (a) receiving a new print job;
• (b) activating a movement mechanism to position a printhead ejection face having a plurality of nozzles over a purge platform, a space is defined vertically between the ejection face and the purge platform;
• (c) activating a fluid supply to force printing fluid out of the printhead and into the space;
• (d) activating the movement mechanism to translate the ejection face over a wiper to remove residual printing fluid from the ejection face;
• (e) activating the movement mechanism to position the ejection face over a spittoon;
• and
• (f) activating the ejection nozzles to eject drops into the spittoon until any purged fluid received by the nozzles is removed.

A computer-readable storage medium for manufacturing a three-dimensional article, the computer-readable storage medium being non-transitory and having computer-readable code portions stored therein that in response to execution by a processor cause an apparatus to perform steps comprising:

• (a) receive a new print job;
• (b) activate a movement mechanism to position a printhead ejection face having a plurality of nozzles over a purge platform, a space is defined vertically between the ejection face and the purge platform;
• (c) activate a fluid supply to force printing fluid out of the printhead and into the space;
• (d) activate the movement mechanism to translate the ejection face over a wiper to remove residual printing fluid from the ejection face;
• (e) activate the movement mechanism to position the ejection face over a spittoon;
• and
• (f) activate the ejection nozzles to eject drops into the spittoon until any purged fluid received by the nozzles is removed.
