Embodiment Construction

[0012] figure 1 is an example additive deposition process 100 according to an embodiment of the invention. The process exploits the charge potential difference between the aerosol droplets and selected portions of the surface of the substrate layer to selectively deposit an atomized liquid additive material onto a substrate. Additive materials can be liquid or liquid materials, such as solid materials that melt into a liquid state. The additive material can be any number of materials, including polymers such as thermoplastics. The material is first fabricated into an aerosol that can be formed in a selective deposition process. The selective deposition of additive material on the surface of the substrate layer results in an efficient process, since undeposited additive material can be recycled and recycled back into the process 100, any excess deposition of additive material is substantially limited. Furthermore, by choosing the surface charge density and controlling the ch...

Abstract

An additive deposition system and method, the system including generating an aerosol of additive material that is charged and deposited onto a selectively charged substrate. Selectively charging the substrate includes uniformly charging a surface of the substrate, selectively removing charged from the substrate to create charged and neutral regions of the substrate surface. The charged regions of the substrate having a polarity opposite a polarity of the charged aerosol. The charged aerosol of additive material deposited onto the selectively charged portions of the substrate surface due to the potential difference between the charged substrate and charged aerosol. The system and method further including repeating the additive deposition process to create a multi-layer matrix of additive material.

Description

Background technique [0001] Custom manufacturing of parts is a growing industry and has a wide range of applications. Traditionally, injection molding machines and other processing techniques are used to form models of objects or to form the objects themselves. More specifically, heated materials like glass, metals, thermoplastics, and other polymers are injected into injection molds that are specifically shaped into the shape of the desired object. The material is allowed to cool in the mold and take the shape of the mold to form an object. Forming injection molds is expensive and time consuming, making it difficult to accommodate changes in the shape of an object without further increasing the time and expense of forming the object. [0002] The additive manufacturing industry emerged in response to the expense, time and difficulty of altering injection molding to form models or objects themselves. Known additive manufacturing techniques include, inter alia, fused deposit...
