    Abstract: Techniques for illuminating an interior of an enclosure in an additive fabrication device are described. According to some aspects, an additive fabrication device includes a build region into which source material may be disposed and at least one source of electromagnetic radiation configured to direct radiation onto the source material in the build region to thereby form a layer of solid material from the source material. A first heater may be included that is configured to heat at least a portion of the source material in the build region. In some embodiments, an enclosure surrounds the build region and comprises a refractive aperture. In some embodiments, at least one light source is arranged to direct light into the enclosure through the refractive aperture.
