Abstract
An embodiment of a method for operating a direct write device includes operating a first pump to deliver a first fluid feedstock to a first inlet of a multiaxial needle and operating a second pump to deliver a second feedstock to a second inlet of the multiaxial needle. At least the first and second feedstocks are simultaneously drawn or injected through respective first and second axial passages in the multiaxial needle. At least the first and second feedstocks are combining to a common outlet of the multiaxial needle, forming a single multicomponent deposition material having multiple discrete phases without applying external heat to the first or second feedstocks within the needle. The multicomponent deposition material is deposited from the common outlet onto a substrate.
