A consumable filament for use in an extrusion-based additive manufacturing system, where the consumable filament comprises a core portion of a first thermoplastic material, and a shell portion of a second thermoplastic material that is compositionally different from the first thermoplastic material, where the consumable filament is configured to be melted and extruded to form roads of a plurality of solidified layers of a three-dimensional object, and where the roads at least partially retain cross-sectional profiles corresponding to the core portion and the shell portion of the consumable filament.

A multi-component micro-pellet useful as a consumable material for making objects by powder based additive manufacturing is disclosed. A method of making said micro-pellet is also disclosed. An object made by using said micro-pellets is also disclosed.

Materials for powder-based additive manufacturing processes

A consumable polymeric based powder mixture may include a plurality of polymeric based particles that have a unitary construction. At least about 80% of the plurality of polymeric based particles may further have a generally cylindrical shape. The plurality of polymeric based particles may further have a particle length distribution span (PLDS) of not greater than about 1.2, where PLDS is equal to (L80&#x2212;L20)/L50.

A chip (12) counter (10) employs an ultrasonic distance measuring system (40) to determine the number of chips in a stack (54, 56) in a chip tray (16) channel (14). A computer (32) initially stores an average chip thickness (T) and receives distance data from the ultrasonic distance measuring system indicative of a first distance (D.sub.1) to the bottom of an empty channel. To count chips, the computer repeatedly receives data from the ultrasonic distance measuring system indicative of a second distance (D.sub.2) to the top of the stack of chips in the channel. The computer subtracts the second distance from the first distance to determine a height of the stack of chips and then divides the height by the average chip thickness to provide a continuous count of the number of chips in the channel. In a multichannel chip tray, each channel has a distance measuring transducer, and a multiplexer (28) scans all the transducers to provide the computer with second distance data for all channels in the chip tray.
