Abstract: A stereolithography system comprises an emitting device and a tank disposed above the emitting device. The tank has a first optically transparent bottom wall and a second optically transparent bottom wall with a space disposed therebetween. There is a linear stage that extends away from the tank and a carrier platform is moveable along the linear stage away from the tank. There is also a wettable material at a bottom wall of the tank within the tank. A fluid cooling system is in fluid communication the space disposed between the first optically transparent bottom wall of the tank and the second optically transparent bottom wall of the tank.

Abstract: A system for three-dimensional printing by selective sintering comprises a first laser, a second laser, and a tank disposed between the first laser and the second laser. The system may further include hoppers in communication with the tank. The first laser, the second laser, and the tank may be aligned either horizontally or vertically.

Abstract: An atmospheric water generator includes a refrigeration system. The evaporators may be roll-bond evaporators. Fans cooperate with a radiator and the evaporators to induce an in-flow stream of air from ambient air into and through, firstly, the condenser, and secondly, the radiator. The in-flow stream of air is cooled by the evaporator as the in-flow stream passes through the evaporator. The cooled stream of air then passes through a heated dissipating section of the radiator. The airways between the evaporators in the array are sufficiently long so that the streams of air become turbulently mixed. The evaporators may be planar. Opposed facing surfaces of adjacent evaporators may include turbulent flow trippers to change laminar flow in the airways to turbulent flow. The turbulent flow trippers may include protrusions formed on the opposed facing surfaces or metallic mesh interleaved in the airways between the evaporators.
