Apparatus, system, and method for use in three-dimensional printing

The present invention concerns a reservoir assembly for use in three-dimensional (3D) printing for building a 3D object, which includes a top frame that may be filled with liquid material, and a tensioned film being held underneath the top frame. The tensioned film may be air permeable and elastic at the same time, wherein surfaces of the tensioned film are micro textured so that the tensioned film becomes optically clear when it contacts with the liquid material. The tensioned film minimizes the creation of bubbles between the top and bottom surfaces. This also helps blurring the boundaries thereby enhancing the surface finish of the fabricated parts.

Method and apparatus for creating and sintering fine lines and patterns

The invention aims to provide a contactless method to create small conductive tracks on a substrate.

Additive manufacturing by light-emitting micro devices in photosensitive material

A method, computer program product, and system. The embodiments include a method for three-dimensional printing of an object. The method provides for one or more processors to receive image data of an object to print. The one or more processors receive a position of a light-emitting robot inserted within photosensitive material. The one or more processors initiate movement of the light-emitting robot within the photosensitive material. The one or more processors control navigation of the light-emitting robot through the photosensitive material, based on continual feedback of the position of the light-emitting robot within photosensitive material and the received image data of the object to print, and the one or more processors control activation and deactivation of emitted light of the light-emitting robot, based on the image data of the object to print, wherein the emitted light of the light-emitting robot solidifies the photosensitive material.

Additively manufactured thermoset polymers for metal plating and metal plated parts formed therefrom

A thermoset resin for forming parts to be metal plated includes a vat photopolymerization (VPP) thermoset resin and an etchable phase disposed in the VPP thermoset resin. The etchable phase is etched from a surface of a part formed from the VPP thermoset resin such that a plurality of micro-mechanical locking sites is formed on the surface of the part. The etchable phase is at least one of organic particles, organic resins, inorganic particles, and copolymers of the VPP thermoset resin. For example, the etchable phase can be a polybutadiene phase and/or a mineral such as calcium carbonate.

System and method for selectively post-curing parts printed with stereolithography additive manufacturing techniques

The present subject matter is directed towards a system and a method for selectively post-curing a three-dimensional (3D-printed) object to attain variable properties. The system comprises a selective post-curing chamber coupled to a computer in communication with a database for accessing a digital model or data concerning the 3D-printed object. The chamber comprises a movable light source assembly and a mounting platform for supporting at least one 3D-printed object thereon. The computer includes one or more executable instructions for selectively emitting a curing light onto the 3D-printed object along a predetermined curing toolpath based on the digital model. The curing of the 3D-printed object along the predetermined curing toolpath generates variable properties along different regions of the 3D-printed object.
