Abstract: Described is a system for producing a three-dimensional (3D) printed radio frequency (RF) absorber. The system includes a computer configured to produce a computer model and a 3D printer. The 3D printer has an extruder controlled by a motor directed by the computer to deposit melted plastic filament loaded with a RF absorber material in computer controlled patterns according to the computer model to produce a RF absorber having a custom profile of desired RF absorption properties and desired dielectric properties.

Abstract: Described is a method for manufacturing a radio frequency (RF) absorber. The method includes first determining a set of desired RF absorption properties for a RF absorber. A computer model for the RF absorber having the determined set of desired RF absorption properties is then produced. Using a three-dimensional (3D) printing process, melted plastic filament loaded with a RF absorber material is deposited in in computer controlled patterns according to the computer model, thereby producing the RF absorber having the set of desired RF absorption properties.

Abstract: Described is a method and system for producing a three-dimensional (3D) structure using 3D printing. A 3D structure, having multiple regions, is produced using a 3D printer having at least one extruder formed to receive a printer filament. The printer filament has at least one type of material having radio frequency (RF) absorption properties. The RF absorption properties are varied at different regions of the 3D structure by varying the extrusion of the at least one type of material at different regions of the 3D structure.
