A method of making a capsule comprising a plurality of compartments, the method comprising: initiating extrusion of a filament solution through a filament extruder； laying the filament solution to form a base of the capsule； forming a first compartment in the plurality of compartments, wherein the forming creates a first barrier wall having a first predetermined release time； forming a second compartment in the plurality of compartments, wherein the forming creates a second barrier wall having a second predetermined release time； filling the first compartment with a first material； filling the second compartment with a second material； and sealing the plurality of compartments thereby forming the capsule with a first sealed compartment and a second sealed compartment.
