Question

binder jetting technologies (bj)
use the information below to answer the questions to the right.
binder jetting requires no polymers. you can use sand or metal as your building agent. it also requires no direct heat.
the process of binder jet printing includes distributing a fine layer of powder onto the print bed. as each layer is spread, the print bed will lower until the final layer is distributed.
a binding agent is a liquid that takes powder and glues it together to make it stick together, and that is how you get the first layer and so on.
the print head knows where the binding agent is to be applied.
the binding agent will need to cure and harden, there is no laser or heat involved in this process.
by not using any heat you are eliminating any opportunity for any internal stress on your print.
what is sprayed in between each layer of powder after it is spread out when using binder jetting?
the colored dye is sprayed
water is sprayed
a binding agent
