1. A method of additive manufacturing, the method comprising:
obtaining a feedstock comprising at least 70% by weight of a metal organic framework adsorbent based on a total weight of the feedstock, and a solid binder;
a) forming a first feedstock layer on a surface, the first feedstock layer comprising the feedstock;
b) applying radiation to a portion of the first feedstock layer to form a first layer of a multilayer composite;
c) forming a second feedstock layer over at least the first layer of the multilayer composite, the second feedstock layer comprising the feedstock; and
d) applying radiation to a portion of the second feedstock layer to form a second layer of the multilayer composite; and
repeating steps a)-d) to form a multilayer metal organic framework composite,
wherein the multilayer metal organic framework composite comprises a non-denatured metal-organic framework adsorbent,
wherein the multilayer metal organic framework composite has a density of at least 0.65 grams metal organic framework adsorbent per cubic centimeter of the multi-layer metal organic framework composite, and
wherein the multilayer metal organic framework composite adsorbs and desorbs gas.
