Todd SumamnoBloom designed by Emerging Objects is a 9 foot tall freestanding tempietto with a footprint that measures approximately 12 feet by 12 feet and is composed of 840 customized 3D printed blocks. The experimental pavilion represents a new paradigm in building construction methods. A pattern derived from traditional Thai flower patterns is mapped onto the surface of the structure that creates a figural pattern and stunning visual effect of light, shade and shadow on the exterior and interior. From the exterior the pattern is most striking from a distance or when viewed through the screen of a digital camera, which creates a surprise upon photographing the structure from up close.
Each block is printed using a farm of 11 powder 3D printers with a special cement composite formulation comprised chiefly of iron oxide-free portland cement. Iron oxide imparts a gray color to cement, and its removal makes this print much lighter. Also, 3D printed cement requires no formwork and produces no waste and the support material can be reused to produce more blocks. Coupled with portland cement is an ecologically derived UV resistant polymer that reduces the greenhouse gas emissions from production of resins by 50% over conventional petroleum based epoxies that uses plant-based materials that do not compete with food sources or displace food-based agriculture. Each 3D printed block is enumerated to designate the blocks position in the overall structure. Rather than a set of blueprints, a spreadsheet that demonstrated the position of a block, was used in constructing Bloom, and each block is assembled and held in place using stainless steel hardware.
