Abstract
Official abstract text for this publication.
Techniques for controlling moisture content of build material in a three-dimensional printer are provided. The system includes a vessel to supply the build material into a build material conveying system. The vessel includes an air inlet to receive a flow of air to fluidize the build material. The system also includes an air conditioner to control the humidity of the air and provide a controlled level of moisture content to the build material.
First claim
Opening claim text (preview).
What is claimed is: 1 . A system for controlling moisture content of build material in a three dimensional printer, comprising: a vessel to supply the build material into a build material conveying system, wherein the vessel comprises an air inlet to receive a flow of air to fluidize the build material; and an air conditioner to control the humidity of the air and provide a controlled level of moisture content to the build material. 2 . The system of claim 1 , wherein the vessel comprises a porous membrane to distribute the flow of air throughout the build material contained in the vessel. 3 . The system of claim 1 , wherein the humidity of the air is controlled to increase the moisture content of the build material. 4 . The system of claim 1 , wherein the humidity of the air is controlled to reduce the moisture content of the build material. 5 . The system of claim 1 , wherein the controlled level of moisture content is based on the build material type. 6 . A method for manufacturing three dimensional objects comprising: passing a flow of air through a vessel to fluidize a build material contained in the vessel; controlling humidity of the air to provide a controlled level of moisture content to the build material; and introducing the build material from the vessel into a build material conveying system. 7 . The method of claim 6 , wherein the humidity of the air is controlled to increase the moisture content of the build material. 8 . The method of claim 6 , wherein the humidity of the air is controlled to reduce the moisture content of the build material. 9 . The method of claim 6 , wherein the humidity of the air is controlled to prevent condensation of water in the build material and the build material conveying system. 10 . The method of claim 6 , comprising transporting the build material through the conveying system to a build enclosure and generating a three-dimensional object from the build material. 11 . A three-dimensional printer, comprising: a vessel to supply the build material into a build material conveying system, wherein the vessel comprises an air inlet to receive a flow of air to fluidize the build material; an air conditioner to control the humidity of the air and provide a controlled level of moisture content to the build material; and a build enclosure to receive the build material from the build material conveying system, wherein the three-dimensional printer forms a three-dimensional object within the build enclosure. 12 . The three-dimensional printer of claim 11 , wherein the vessel comprises a porous membrane to distribute the flow of air throughout the build material contained in the vessel. 13 . The three-dimensional printer of claim 11 , comprising a second build material conveying system to transport excess build material from the build enclosure to a recovered material vessel. 14 . The three-dimensional printer of claim 11 , wherein the humidity of the air is controlled to reduce the moisture content of the build material. 15 . The three-dimensional printer of claim 11 , wherein the humidity of the air is controlled to increase the moisture content of the build material.
