Abstract
A method of manufacturing an ordered cellular structure including a series of interconnected unit cells. Each unit cell includes at least one straight wall segment. The method includes irradiating a volume of photo-monomer in a reservoir with at least one light beam from at least one light source to form the ordered cellular structure. Irradiating the volume of photo-monomer includes directing the at least one light beam though a series of interconnected apertures defined in a photo-mask covering the reservoir.
Claims19
A method of manufacturing an ordered cellular structure comprising a plurality of interconnected unit cells, each unit cell of the plurality of interconnected unit cells comprising a plurality of interconnected solid, straight wall segments extending in a same direction from a first end of the unit cell to a second end of the unit cell opposite the first end, the method comprising:
- irradiating a volume of photo-monomer in a reservoir with at least one light beam from at least one light source to form the ordered cellular structure;
- wherein the irradiating the volume of photo-monomer comprises directing the at least one light beam though a plurality of interconnected apertures defined in a photo-mask covering the reservoir,
- wherein the plurality of interconnected solid, straight wall segments of each unit cell are arranged in a closed loop,
- wherein each unit cell of the plurality of interconnected unit cells is open at the first end and the second end, and wherein each unit cell comprises a pre-ceramic polymer.
