Data aggregation and analytics for digital manufacturing

A method for collecting data from 3-D printers, using a message queuing system coupled in communication over a network with a plurality of 3-D printers via aggregator software to one or more subgroups of respective individual 3-D printers, the method including:

• the message queuing system providing, for group administration, at least one party-line queue and using the party-line queue to broadcast messages to the 3-D printers, as a group;
• the message queuing system further providing, for individual administration, a plurality of private-line queues and using the private-line queues to exchange messages with respective 3-D printers, individually and privately;
• and
• wherein using the private-line queues further includes the message queuing system sending the respective printers in response to pull requests and receiving data from the respective printers without imposing flow control and without dropping parts of the data.

A non-transitory computer readable medium impressed with instructions for collecting data from 3-D printers, using a message queuing system coupled in communication over a network with a plurality of 3-D printers via aggregator software to one or more subgroups of respective individual 3-D printers, that, when executed on hardware, cause the hardware to take actions including:

• the message queuing system providing, for group administration, at least one party-line queue and using the party-line queue to broadcast messages to the 3-D printers, as a group;
• the message queuing system further providing, for individual administration, a plurality of private-line queues and using the private-line queues to exchange messages with respective 3-D printers, individually and privately;
• and
• wherein using the private-line queues further includes the message queuing system sending the respective printers in response to pull requests and receiving data from the respective printers without imposing flow control and without dropping parts of the data.
