Powder Removal from 3D Structures
One of the limiting factors for the use of EBM in manufacturing is the difficulty in removing the "cake" powder in small passages of produced pieces.
I don't recall seeing this patent that was issued last September. http://www.flintbox.com/public/filedownload/6740/U.S.%20Patent%208,828,311
I came upon this today. UTEP will license the process.
Powder Removal from 3D Structures
Short Description
The University of Texas at El Paso seeks a partner for licensing on a metal powder removal method from three dimensional structures.
Abstract
Dry sonication is utilized to remove unmelted powder following electron and laser beam melting processes using additive manufacturing.
Advantages
Easily removing non-melted metal powder from hard-to-reach locations in three dimensional structures
Prevents faulty orthopedic implants and revision surgery
Potential Applications
Biomedical - orthopedic implants
Additive manufacturing
Three dimensional printed structures
I believe that there will be numerous commercial/aerospace applications as well.
