BAMBOO JOINT STRUCTURE
TECHNOLOGY 3D Printing technology has been widely used many fields including design, science and industry. It has the advantage of its precision and involves less professional/trade-specific workers. But 3D Printing has rarely been applied in the field of architecture, and almost never in affordable housing projects, due to the greatly increased cost of these larger scale project constructed at a full scale.
APPLICATION TO TRANSFORM THE ARCHITECTURE INDUSTRY In this Bio-Structure project, our concept is to utilize 3D technology in the most efficient way (i.e. to maximize the efficiency and minimize the cost). Thus, in this design, in order to make it much more economical and applicable in architecture, the 3D printed steel joints are the only parts which require high-tech industrial process. All the joints are printed within the dimension of 2”x 2”x 2” with the weight less than 70g. It means that the total weight of the joints needed (46-50 pieces) for building one structure is less than 3.5kg, and they can be packed in a 6” x 6” x 6” box for convenient transportation to anywhere needing affordable housing settlements. Local residents could build their neighborhoods without hiring any professionals, the whole process only needs 3 family members, a bag of concrete, and bamboo sticks .
APPLICATION TO TRANSFORM THE CONSTRUCTION PROCESS The 3D printed joints are the key to a successfully built Bio-Structure, because they are designed to easily locate, orient and connect the bamboo sticks 3 dimensionally in a very precise way. First, the family members fill the bamboo sticks with concrete as both supporting and adhesive material, then attach all the bamboo sticks (all in same length) on every M-joint  to build the structural parts, and finally connect all the structural parts with S-joints  to build the whole Bio-Structure settlement. This whole process could be completed by one family without any professionals or skilled construction workers. In this way, the Joint Design significantly minimizes the labor cost and simplifies the entire construction process.  Bamboo species are found across the global south, in diverse climates. There are two kinds of joint for different function: 1, Modular joins (M-joint): each M-joint will group 2-3 bamboo sticks into individual structure modular. 2, Structure joints (S-joint): the structure joins will group all the structure parts into a final structure for settlement.
