A method for continuously forming a three-dimensional body from a mixture, the mixture comprising at least 15 vol % solid particles and a radiation curable material. The method allows the continuous production of three-dimensional bodies comprising to a high content ceramic particles at a forming speed of at least 25 mm/hour.

Method for forming a three dimensional body from a mixture with a high content of solid particles

Systems and methods are disclosed that include an additive manufacturing assembly having a printing area, a first nozzle comprising a first nozzle having a first aperture diameter and configured to dispense a first material in the printing area, and a second nozzle comprising a second nozzle having a second aperture diameter that is larger than the first aperture diameter and configured to dispense a second material in the printing area.

Additive manufacturing assemblies and methods

A method of forming a three-dimensional body from a mixture, wherein the mixture can comprise dispersed solid polymeric particles and a curable binder. In a particular embodiment the solid polymeric particles can be fluoropolymeric particles. The method can include at least partial removal of the cured binder and sintering, to obtain a sintered polymeric three-dimensional body. In one embodiment, the sintered three-dimensional body can be PTFE.
