Abstract

Atomic layer deposition in a fluidized bed is utilised for the coating of polyamide powders with thin films of silicon dioxide. By varying the number of exposure cycles the amount of deposited material can be precisely controlled, allowing for tailoring wetting, flowing, and melting behaviour of the powder. The favourable process operation characteristics enable a facile envisioning of scalable production in volumes complying with the demands of 3D printing applications.
