Do you already have a printer, or are you in the market for one to integrate with our extruder?
As long as the printer you are using is compatible with the Discov3ry paste extruder, the quality of the prints will be more affected by the quality of the printer itself.
Therefore, a printer that prints better plastic prints will most likely print better paste (and chocolate) prints.
As for the question of compatibility, you can evaluate different printers by asking the following questions of the manufacturer, or reviewing their technical specifications if available.
1) Are your electronics based off the RAMPs architecture? Are they accessible?
2) Does your printer work with open-sourced software?
3) Are you nema17 stepper motor based?
4) Do you have dual extrusion capabilities with a second motor driver? (This is optional, but nice to have).
There is no discount for purchasing two units, though if you are outside Canada, you will only need to pay the shipping once, saving you $25.
Very happy to answer any more questions you might have.
