Abstract
Disclosed is a powder build material handling system for a three-dimensional printer. The system comprises a delivery system. The delivery system is to carry powder build material in a flow of gas from a powder build material supply. The delivery system is to filter the flow of gas to separate the powder build material from the flow of gas. The delivery system is to direct the filtered flow of gas to the powder build material supply to form a closed system.
Claims17
A powder build material handling system for a three-dimensional printer, the system comprising:
- a reservoir at a location physically separate from a build area, to store a supply of powder build material;
- and
- a delivery system to carry powder build material in a flow of gas from the reservoir, to filter the flow of gas to separate the powder build material from the flow of gas, to deposit powder build material separated from the flow of gas to a powder deposition zone in the build area, and to direct the filtered flow of gas to the reservoir to form a closed system.
A method for a three-dimensional printer, comprising:
- storing a supply of powder build material in a reservoir at a location physically separate from a build area of the printer;
- transporting, in a flow of gas, powder build material from the reservoir;
- filtering the flow of gas to separate the powder build material from the flow of gas;
- depositing powder build material separated from the flow of gas to a powder deposition zone in the build area;
- and
- returning the flow of gas to the reservoir after the filtering.
