Abstract: Clean chamber technology for 3D printers and bioprinters is described. An airtight chamber or enclosure is provided so that positive pressure can be created inside the chamber. Unfiltered air is sucked in from outside into the chamber through a high efficiency filter such as a HEPA filter, using an electrically powered fan or blower, filtering out at least about 99% of particles and contaminants. The filtered air is then pushed into a 3D printing area inside the chamber and out through vents within the frame of the chamber. The technology provides a clean environment for 3D bioprinting of human tissue models and organs and 3D cell culturing without requiring clean room facilities.

Abstract: The present invention and its variations provide a method of Fused Deposition Modeling (FDM) 3D Printing at a high rate of speed, much higher than that of a conventional 3d printer (e.g. 5 meters per second travel, depositing 3 cubic centimeters of material per second). The invention uses a closed loop brushless motor control system to rapidly move a carriage to a precise position. This carriage contains on itself a high-flow-rate hot end, which is a device which can liquify material at a high flow rate, which in turn is used to deposit material onto a heated bed. The printer contains a high-flow-rate extruder, which is a device designed to maximize the friction between a belt and a pulley in order to drive a large amount of material filament through the high-flow-rate hot end onto a bed without slipping.

A first of the automated constructors may include a 3-D printer to print at least a portion of a component and to transfer the component to a second one of the automated constructors for installation during the assembly of the transport structure. The automated constructors may also be adapted to perform a variety of different tasks utilizing sensors for enabling machine-learning.

Abstract: The invention relates to the field of the additive manufacturing of components, which are formed by the direct deposition of a substance, in the form of granules of a metal or non-metal, which passes from a reservoir into a melt bath, produced by the thermal energy of a laser or electron beam, and subsequently crystallizes. The granules enter the melt bath without the intervention of a gas stream, the path and rate of travel of said granules changing while they are in flight under the effect of an electromagnetic field. The granules travel within a chamber, falling into the melt bath from above from a reservoir, from which they are fed at a set speed by the rotation of an adjustable screw feed, and passing through a system of electromagnetic devices, which control the path of the granules by means of electromagnetic fields.

Abstract: Techniques for illuminating a photocurable material within a build area of an additive fabrication device are described. According to some aspects, a light source is provided that can be moved alongside a build area, allowing light to be directed to any desired position within the build area by moving the light source.

The described approach may allow for fabrication of larger parts in an additive fabrication device by expanding or eliminating the practical upper limit on the area of the build volume that can be imposed by use of a laser light source in such a device.
