Abstract: A disposable tank and build platform for a 3D printer are disclosed. The container is pre-filled and sealed with light-cured resin. The build platform is a surface to which the printed part adheres during the printing process. The build platform allows for application-specific containers to minimize resin waste during small print batches. The container further comprises a print screen. The print screen is a surface that allows light to pass through to cure the resin. The container with the light-cured resin is configured to allow operators to go through the print process with minimal resin handling and eliminates the need to measure the amount of resin during setup. Further, the container and build platform may come in a type of cartridge that is used up to build specific components such as dental appliances.

Abstract: A repair system for use in repairing a component includes an elongated repair tool having a first end that supports an electrode and a second end opposite the first end. A camera has a field of view and is fixedly attached to the elongated repair tool such that the electrode is within the field of view. A power supply is coupled to the electrode and is operable to deliver an electrical current to the electrode, the electrical current sufficient to form an arc between the electrode and the component to remove material from the component, where the second end of the elongated repair tool is movable to position the electrode in a desired position.

Abstract: A cartridge including a tank and build platform for a 3D printer is disclosed. The cartridge is pre-filled and sealed with resin. The build platform is a surface to which the printed part adheres during the printing process. The build platform allows for application-specific cartridges to minimize resin waste during small print batches. The cartridge may include surface that allows light to pass through to cure the resin. The container with the light-cured resin is configured to allow operators to go through the print process with minimal resin handling and eliminates the need to measure the amount of resin during setup. Further, the container and build platform may come in a type of cartridge that is used up to build specific components such as dental appliances.

Abstract: A kit for retrofitting an existing three-dimensional (3D) printer and a method of retrofitting an existing a 3D printer are disclosed. The kit includes a kit adapter that comprises a resin reservoir. The reservoir includes a bottom print surface, the kit adapter adapted to register with an existing screen of the 3D printer. The method includes the steps of providing a kit adapter including a kit resin reservoir including a kit bottom print surface, the kit adapter adapted to register with the existing screen; registering the kit adapter with the existing screen thereby covering a second portion of the existing screen with the kit bottom print surface and thereby configuring the kit bottom surface to receive the curing light from the second portion of the existing screen only, wherein the second portion of the existing screen is contained within the first portion of the existing screen.

Abstract: A coil is produced by wrapping a primary winding of the coil onto a core rod of a wrapping machine, arranging a secondary winding of the coil on a winding form and pushing it coaxially over the primary winding, pulling the core rod out of the primary winding, simultaneously inserting an iron core into the primary winding, and moving along a housing which accommodates the iron core onto the ignition coil, and filling the housing with casting resin to form a plastic block which surrounds at least the primary winding.
