Claim 17:
18. The microthruster of claim 12, wherein
the first layer and the second layer define an array of nozzle throats positioned between the first layer and the second layer, the array of nozzle throats being bounded on one side by the first layer or the second layer,
each of the nozzle throats of the array of nozzle throats defining an ejection direction along which propellant is expelled,
each of the nozzle throats of the array of nozzle throats being in fluid communication with the propellant reservoir,
the propellant reservoir being further defined by pairs of side walls, each pair of side walls being adjacent to a nozzle throat of the array of nozzle throats, and
the pairs of side walls form a saw tooth pattern, wherein each side wall of each pair of side walls is angled with respect to the nozzle throat to which each side wall is adjacent by at least 120 degrees and at most 165 degrees.
