Claim 17:
18. A method for selectively patterning a dense sinterable additive manufactured feedstock structure into a 3D part with a 3D printing system, the method comprising:
a) forwarding a web sheet having a layer of dense feedstock in a process direction with a transfer subsystem of a printing system, the feedstock being a dense sinterable material and binder composite with porosity below 20% volume, the layer of dense feedstock being a dense feedstock 3D slice having imaging areas thereon;
b) selectively depositing a sintering ink according to a 3D pattern onto the imaging areas of the dense feedstock 3D slice, the sintering ink infiltrating into the dense feedstock 3D slice to form a patterned dense feedstock slice in accordance with the 3D pattern;
c) winding the patterned dense feedstock slice over a previously formed patterned dense feedstock slice section to form a build monolith;
d) removing at least some of the binder composite from the build monolith; and
e) sintering the build monolith into the 3D part shaped based on the 3D pattern.
