Claim 5:
6. A printer heater comprising:
a lamp extended along a longitudinal filament axis to emit radiant energy;
a reflector comprising a reflective surface positioned to direct radiant energy from the lamp toward a receiving surface to heat a build material on the receiving surface, the reflector extended parallel with the longitudinal filament axis; and
a radiant energy absorbing baffle comprising a plurality of lateral baffles disposed between the lamp and the reflector, wherein individual lateral baffles of the plurality of lateral baffles comprise a radiant energy absorbing plate that extends laterally through the reflective surface and is positioned to absorb at least a portion of a reflection of the radiant energy reflected from the receiving surface to limit re-reflection of the portion of the reflection of the radiant energy by the reflecting surface back to the receiving surface; and
wherein the plurality of lateral baffles extend around a portion of the lamp in a circumferential direction.
