Abstract: A system and method for continuous additive manufacturing of objects is provided. The system includes a container configured to receive a photopolymer and a print bed disposed within the container. An first end effector is movably disposed within the container. A light source is operably coupled to the first end effector, the light source being configured to emit and electromagnetic radiation. Wherein at least one of the print bed or first end effector is movable relative to the other to perform continuous separation curing of the photopolymer on the print bed with the electromagnetic radiation.

Abstract: Systems, apparatus, and methods are described for additive manufacturing or three dimensional (3D) printing of objects using a set of physical masks. An additive manufacturing device can include one or more light sources, a vessel containing a volume of print material and a transparent base through which light can enter the vessel to cure a portion of the volume of print material, and a set of masks defining a series of patterns associated with layers of a 3D object that are each positionable between the light source and the transparent base to control a pattern of the light that is received through the transparent base and therefore the pattern of the cured portion of print material.

Abstract: An apparatus and a method of additive manufacturing is provided. The apparatus includes a light source configured to emit light between 0 and 500 nm in wavelength. At least one vessel is provided that includes a chamber and a transparent base. The chamber contains a volume of liquid print material. The transparent base being made of Fluorinated ethylene propylene (FEP) or Polydimethylsiloxane (PDMS) through which the relevant wavelength can be received into the chamber to cure a portion of the volume of print material through at least one mask, the at least one mask being made of paper, polymer, glass, metal, composites, or laminated substrates, the at least one mask defining a series of patterns associated with layers of a three-dimensional (3D) object, the at least one mask being position-able between the light source and the transparent base, via a mechanism, wherein the at least one mask defines the pattern of the light that is received through the transparent base and into the print material.

Abstract: An additive manufacturing device and a method of fabricating a 3D object is provided. The device includes a vessel configured to rotate about an axis and a membrane disposed to form a floor of the vessel. A build plate is movable between a first position and a second position, the build plate being positioned a predetermined distance apart from the membrane in the first position. A light source is arranged to direct electromagnetic radiation through the membrane towards the build plate. A processor is provided that is responsive to executable computer instructions for rotating on a periodic, aperiodic, or continuous basis, the vessel to oxygenate the membrane.

Abstract: An additive manufacturing system is provided including a light source configured to emit light, a vessel configured to contain a photopolymer, and a bed having a surface disposed at least partially within the vessel. The surface is movable in a first direction relative to the light source. A membrane is fixed to the vessel and is positioned between the light source and the photopolymer. A movable carrier is disposed between the light source and the membrane. The light source is operably coupled to the movable carrier.
