Abstract: Systems and methods for providing a component to and/or removing a component from a printer enclosure of an additive manufacturing system. A chamber may be configured to removably receive and hold a component such as a build volume having a build surface on which a manufactured part is to be formed. One or more portions of the chamber may interact with the component to define a sealed internal space that may be isolated from an external environment and/or purged with inert gas. The chamber and component may be moved independent of a printer enclosure while the sealed internal space is isolated, and the chamber and printer enclosure may sealingly engage for transfer of the component from the chamber into and/or out of the printer enclosure.

Abstract: System and method for dispensing powder material for an additive manufacturing system. A hopper can include a spline configured for rotation to dispense powder material from an exit opening of the hopper. A shield can be provided for one or both ends of the spline to help control powder movement at an interface with the spline, e.g., so powder that passes the interface is trapped in a space. An auger can be provided in a hopper and configured for moving powder in the hopper in two opposed directions in response to rotation of the auger in a single direction. A common drive can be used to move both an auger and spline. One or more load cells can be provided to determine a mass of powder delivered to and/or dispensed from the hopper.

Abstract: System and method for dispensing powder material for an additive manufacturing system. A preload container can be configured to hold a predetermined amount of powder material, and move the powder material from a powder supply to a powder recoater. The preload container may be configured to hold an amount of powder suitable for forming multiple powder layers on a build surface and may be configured to rapidly deliver the powder material to a powder recoater, e.g., in less than 10 seconds. The powder material in the preload container and/or the powder supply may be maintained in an isolated environment, e.g., during transfer of powder material from the powder supply to the preload container. A seal may have a movable portion configured to interface between the powder supply and a recoater hopper.

Abstract: Disclosed embodiments are generally related to recoater assemblies for additive manufacturing systems. In some embodiments, a recoater blade may include a plurality of flexible portions that are configured to deflect relative to one another when moved over and past a defect on a build surface. In other embodiments, a recoater assembly may include compliant attachments that exhibit compliances that increase in an outward direction relative to a central portion of a body of the recoater assembly. In still other embodiments, a pair of scoops may be disposed on opposing end portions of a recoater blade and/or recoater assembly to help guide and collect excess powder dispensed onto a build surface.

Abstract: A hopper for dispensing powder material for an additive manufacturing system includes a gate that is movable along a first direction to open and close a discharge slot and which is pivotable about a pivot axis transverse to the first direction. The first direction can be a horizontal direction and the pivot axis can be parallel to a vertical direction. The gate can have a portion that contacts the hopper, e.g., at a surface including the discharge slot, and is elastically deformed with movement from the open to the closed position.

Abstract: An electrostatic recoater having an electrode and dielectric shield mounted to a lower surface of the electrode. The dielectric shield and electrode can be movable relative to each other at an interface and/or the dielectric shield may be removably mounted to the electrode.

Abstract: A support for a build table for use with an additive manufacturing system. Two or more actuators may be coupled to the build table and configured to move the build table in a Z direction, e.g., for deposition of multiple precursor material layers, and rotate the build table about axes parallel to a build surface, e.g., to level the build surface. Couplings for one or more actuator may provide pivotal movement about at least two orthogonal axes and linear movement along only one direction parallel to the build surface.

Abstract: In various embodiments of an analytics system, a spike-in including synthetic constructs of nucleic acid is added to soil samples for processing. The analytics system determines sequence reads classified to a microbe in the soil sample. The analytics system determines one or more measures of soil texture of the soil sample, for example, indicating percentages of sand, silt, and clay. The analytics system determines a measure of the microbe as a function of at least the classified sequence reads, the one or more measures of soil texture, and a mass of the spike-in. The analytics system can transmit the measure of the microbe to a client device for display on a user interface. A field where the soil sample was obtained can be treated according to the measure of the microbe.

Abstract: A drop seeder apparatus includes a frame and a bottom plate having a plurality of through holes. A top plate has a plurality of through holes. The top plate is secured in the frame and positioned in a sliding relationship with respect to the bottom plate. A system of legs is configured to adjust a length thereof to accommodate seed trays of varying heights. A slide actuation system is configured to allow a user to slide the top plate across the bottom plate and cause the top plate to automatically return to a default trap position.

The analytics system determines a measure of an agronomic attribute of the soil at the geographical location as a function of the first, second, and third sets of measures.

Abstract: An analytics system uses metagenomics to generate predictions indicating performance of biological or physical samples. In an embodiment, a method includes determining sequence data of a soil sample. The method further includes determining a plurality of features of the soil sample using the sequence data. The plurality of features is determined based at least in part on a measure of a first microbe detected in the soil sample and a different measure of a second microbe detected in the soil sample. The method further includes inputting the plurality of features to a model trained using measures of the first microbe and the second microbe detected in a plurality of soil samples. The method further includes generating, by the model using the plurality of features, a prediction of physical attribute of a plant grown in the soil sample.

Abstract: Provided herein are systems and methods for printing a 3D object on a pliable substrate. In some aspects, the pliable substrate is moved through a vat of polymeric precursor while a mechanism (e.g., having opposing belts) maintains contact with the peripheral edges of the substrate. The systems and methods described herein can have certain advantages, such as precise control over the pliable substrate, allowing for precision printing of 3D articles.
