A three-dimensional printing system includes a build platform comprising a build surface. The printing system also includes an enclosure system having a side portion extending entirely around the build surface, a top plate portion that abuts the side portion, and a bottom portion. The side portion, the top plate portion and the bottom portion form an enclosed space surrounding the build surface. The top plate portion is moveable so as to adjust a volume of the enclosed space. A 3D printer printhead is disposed adjacent to the enclosure system for depositing a print material onto the build surface. The printing system also includes a heating system for heating the enclosed space.
