Basics

A Modular Print Farm Utilizing the D3D Pro (for precision, small nozzle parts), A Large D3D For Large Parts, and perhaps a D3D Belt Printer for long parts
These then eject their parts using the Open Source Automated Printed Part Remover (may need better name)
They are then rearranged by either some sort of D3D Pick and Place Machine , or something like Delta X to "fit properly" on the feed conveyor belt
This then leads to the "main conveyor belt" which can feed to automated post processing, assembly, packaging, or simply a bin for non-automated use
Can be expanded overtime by adding extra "feed belts", "Main Belt" modules
The gap between feed belts acts as maitnence access, allowing for easy troubleshooting, and replacement of printers etc
With Octoprint this can essentially make a click to print process possible (assuming no print falures etc)
Computer Vision could perhaps be implemented to monitor this

Basic Design

Note That this is asuming 2-3 feed belts with 10 printers each, this system could even work with 1 or 100 printers
10x D3D Pro with 0.2mm nozzle
10x Large D3D With Largest Nozzle Possible
?x D3D Belt Printers (if even used)
2-3x "Feed" (ie shorter) Open Source Conveyor Belts
1x (perhaps multiple smaller belts with small gaps in between if need be) "Main" Open Source Conveyor Belt
Open Source Overhead Camera for Computer vision on belts
3 Pick and Place Devices (Either Delta X or D3D Pick and Place Machines )
3-4 "waste" bins or something similar (by each pick and place, for automaticc removal of failed parts etc
20-30x Open Source Automated Printed Part Removers

A YouTube Video by the YouTube Channel "Ali Aburaia" Titled "3D Printer Farm - Robot-based Automation" (Seems to utilize a 3x3 Grid of Prusa MK3s-es (or some similar model), an X+Z Gantry (is that the right term?) that moves the print surface to the part separator, a part separator with a "bender" using flexible grippers for separating parts via a Removable Flex Steel Print Surface , and an integrated "pusher". Also has bins for storage of produced parts (and the real amazing part is all the software/firmware that keeps the thing going probably, but good example setup even if just considering hardware)
