Benefits of technology

This patent describes a method of additive manufacturing using cold spray and laser energy application to create smooth layers of powder. The method allows for inspection of the powder layer to detect any defects and removal of the smooth layer if necessary. The system includes a build area, a cold spray powder deposition system, and an energy applicator, which can fuse the powder layers to create a product. The method and system have the technical effects of improving the quality and efficiency of additive manufacturing processes.

Problems solved by technology

However, the processes are slow due to the time spent spreading or rolling a new layer of powder after each layer is joined through laser welding.

Embodiment Construction

[0017]Reference will now be made to the drawings wherein like reference numerals identify similar structural features or aspects of the subject disclosure. For purposes of explanation and illustration, and not limitation, an illustrative view of an embodiment of a system in accordance with the disclosure is shown in FIG. 1 and is designated generally by reference character 100.

[0018]Other embodiments and / or aspects of this disclosure are shown in FIG. 2. The systems and methods described herein can be used to improve build quality and reduce time consumed in additive manufacturing.

[0019]Referring to FIG. 1, an additive manufacturing system 100 can include a build area 101 and a cold spray powder deposition system 103 configured to cold spray powder onto the build area 101 to create successive densified powder layer. While the build area 101 is shown as a moveable build platform (e.g., similar to those used in a roller bed system), any suitable build area is contemplated herein (e.g....

Abstract

An additive manufacturing method includes cold spraying a powder onto a build area to create a densified powder layer. The method can include high speed machining the densified powder layer after cold spraying to create a smooth layer.

Description

BACKGROUND1. Field[0001]The present disclosure relates to additive manufacturing, more specifically to powder deposition for additive manufacturing.2. Description of Related Art[0002]Current commercial powder bed laser fusion systems can create consolidated parts or structures through metallurgical bonding of powder feed stock. However, the processes are slow due to the time spent spreading or rolling a new layer of powder after each layer is joined through laser welding.[0003]Such conventional methods and systems have generally been considered satisfactory for their intended purpose. However, there is still a need in the art for powder deposition for additive manufacturing. The present disclosure provides a solution for this need.SUMMARY[0004]An additive manufacturing method includes cold spraying a powder onto a build area to create a densified powder layer. The method can include high speed machining the densified powder layer after cold spraying to create a smooth layer.[0005]Th...
