Abstract: A 3D printing system includes a tank including an optically transparent window through which light is configured to pass. A polymer layer is disposed on the optically transparent window. The polymer layer is optically transparent such that light is configured to pass therethrough. A plurality of pillars extend upwardly from an upper surface of the polymer layer to define a textured substrate. Each of the plurality of pillars includes a magnetic material. A layer of an inert material is disposed on the polymer layer. A liquid photopolymer resin is disposed on the layer of the inert material.

Abstract: A three-dimensional printing system includes a tank containing a liquid photopolymer resin. An arm is configured to be movable relative to the tank. A rigid base is connected to the arm. A light source is configured to emit light to the tank to form an object on the rigid base. An actuator is connected to at least one of the build plate and the tank. The actuator is configured to deform when power is supplied to the actuator.

Abstract: A three-dimensional printing system includes a tank containing a liquid photopolymer resin, a rigid base on which an object is configured to be printed, and an arm connected to the rigid base to move the rigid base relative to the tank. A first light source is configured to emit light to the tank to form the object on the rigid base. A first pair of rollers are configured to receive the object therebetween. The first pair of rollers are configured to pull the object in a direction out of the tank. A first post-processing station is configured to receive a first end of the object while a second end of the object is being formed in the tank.

Abstract: It is described a foldable articulated arm comprising a first rod-shaped element, a second rod-shaped element and a third rod-shaped element foldable one another and at least three stretching element of the rod-shaped elements, arranged to form a system of four-bar linkages, further comprising a plurality of joint elements of the rod-shaped elements and the stretching elements and having, at the opposite ends, a retaining mechanism for a respective combining with a tube and an umbrella sheet, wherein the rod-shaped elements, the joint elements, the stretching elements and the retaining mechanism are all made integral in a single piece of plastic material constituting the foldable articulated arm.
