Abstract: In some examples, a printer includes a feed mechanism to distribute a build material on a platform and a heater. The heater includes a lamp, a reflector, and a radiant energy absorbing baffle located between the lamp and the reflector. The lamp and the reflector are to direct radiant energy toward the platform, and the radiant energy is to heat the build material.
