Claim 9:
10. An apparatus for printing a manufacturing object by additive manufacturing using solvent melding, said apparatus comprising:
a build box;
a build material reservoir holding granulized build material;
a recoater connected to said build material reservoir;
a solvent reservoir holding at least one solvent configured to meld the build material;
a printhead configured for at least two-dimensional movement within the build box and in fluid connection with the solvent reservoir;
a melding control subsystem comprising:
a control device fluidly interposed between the solvent reservoir and the printhead;
one or more sensors comprising a temperature sensor, a humidity sensor, and a barometer;
one or more databases comprising data regarding optimal deposit concentrations for various solvents at various conditions, said conditions comprising temperature, humidity, and air pressure; and

one or more controllers in electronic communication with said a melding control subsystem and comprising software instructions stored at one or more electronic storage devices, which when executed, configure one or more processors to:
receive uploaded build data for said manufacturing object;
command said recoater to individually deposit multiple layers of said granulized build material within the build box;
determine a type of the build material utilized and a type of the at least one solvent utilized by extraction from the build data;
determine said conditions by way of said melding control subsystem;
query the one or more databases to determine an optimal deposit concentration for said at least one solvent based on said conditions; and
command said printhead to, individually and after each of said multiple layers of said granulized build material are deposited by said recoater, deposit said at least one solvent at areas of each respective one of said multiple layers of said granulized build material in accordance with said build data while also operating said control device to provide said deposit of said at least one solvent at the optimal deposit concentration within said build box.
