APPARATUS, SYSTEM AND METHOD OF HEAT FILTERING FOR ADDITIVE MANUFACTURING
An apparatus, system and method for additive manufacturing. The apparatus, system and method include at least a print bed having thereon powdered print material; a dispersing head suitable to disperse one or more heat-actuated agents onto the powdered print material as indicated by a print plan; a broadband infrared energy source suitable to pass over the print bed so as to actuate the dispersed agent; and a heat energy filter interfaced to the broadband energy source so as to filter the actuating energy to one or a range of wavelengths of the infrared energy source that is less than the available broadband.
1 . An apparatus for additive manufacturing, comprising:
a print bed having thereon powdered print material;
a dispersing head suitable to disperse one or more heat-actuated agents onto the powdered print material as indicated by a print plan;
a broadband infrared energy source suitable to pass over the print bed so as to actuate the dispersed agent; and
a heat energy filter interfaced to the broadband energy source so as to filter the actuating energy to one or a range of wavelengths of the infrared energy source that is less than the available broadband.
2 . The apparatus of claim 1 , wherein the filter is automated.
3 . The apparatus of claim 2 , wherein the automated filtering corresponds to a type of the powdered print material.
4 . The apparatus of claim 1 , wherein the heat energy filter comprises a first filter in a plurality of stacked filters.
5 . The apparatus of claim 4 , wherein the plurality of stack filters comprises filters actuated by electromagnetic energy.
