A laser consolidates the self-limiting electrosprayed green body allowing for targeting by the spray to create a new layer.
Invention Summary:
Laser direct write is a high precision, maskless laser fabrication technique with wide use in microelectronics, flexible circuits, semiconductor manufacturing, etc. However, material selection is limited, printing multiple materials is extremely difficult, and limited throughput restricts the thickness of materials.
Rutgers researchers have developed a method combining their previously developed electrospray techniques with laser direct write. This advanced manufacturing technique enables the synthesis of multimaterial composites, vastly increases the range of compatible materials, and makes the deposition of multiple layers simple, including conversion to full additive manufacturing of 3D objects. Specific component(s) are added to the laser direct write toner for compatibility with self-limiting electrospray deposition. These materials can then be removed and recycled during the manufacturing process. Self-limiting electrospray also reduces the materials waste by making the layers “on-demand” in the written regions.
