The present disclosure relates generally to curable resins, in particular latent cure resins, and related methods for use in an additive fabrication (e.g., 3-dimensional printing) device.

According to one example, there is provided an apparatus to process volume of particulate build material. The apparatus comprises a sealable chamber to house a volume of particulate build material, a gas supply to supply the chamber with a predetermined gas, a gas circulator to circulate the gas within the volume of build material, a temperature controller to heat the circulated gas to a predetermined heating temperature to heat the volume of build material to the heating temperature and then to cool the circulated gas to a predetermined cooling temperature to cool the volume of build material to the cooling temperature.
