Patent Images
1. A system for printing a three-dimensional object, the system comprising:
- an energy source configured to generate an energy beam for transforming a pre-transformed material to a transformed material as at least a portion of the three-dimensional object;
a platform configured to support the three-dimensional object during printing; and
an enclosure configured to enclose at least a portion the platform, which enclosure comprises;
(i) a first wall;
(ii) at least one window configured to allow the energy beam to pass through;
(iii) a region recessed in the first wall, which region comprises the at least one window; and
(iv) a second wall that at least partially separates the region from the first wall, which at least one window and second wall at least partially define a volume of the region.
