Modular 3D printing using a robot arm

A three-dimensional printer system comprising:

• a base plate;
• a plurality of resin containers comprising at least a first resin container and a second resin container;
• a plurality of light sources, wherein at least one light source is arranged below each resin container;
• a robotic device having the base plate attached thereto, wherein the robotic device is operable to move the base plate between the plurality of resin containers such that the base plate is positionable above each of the resin containers while a layer of resin is being formed on the base plate, and wherein the robotic device is operable to move the base plate with at least two degrees of freedom such that a build volume of the three-dimensional printer system extends beyond the edges of the resin container and has a horizontal cross section that is larger than the horizontal cross section of the resin container;
• and
• a control system that is operable to:
• (a) receive data specifying a three-dimensional structure;
• and
• (b) based at least in part on the specified structure, generate control signals that coordinate movement of the base plate by the robotic device and operation of the plurality of light sources to form the three-dimensional structure from layers of resin, wherein at least a first layer of resin is formed by exposure of resin in the first resin container to electromagnetic radiation from the at least one light source under the first resin container, and at least a second layer of resin is formed by exposure of resin in the second resin container to electromagnetic radiation from the at least one light source under the second resin container.
