Abstract

Apparatus and methods for removing and/or destroying support structures associated with objects fabricated using additive manufacturing techniques are presented herein. Structural supports may be used during an additive manufacturing process to prevent deformation of a build piece (e.g., three dimensional (3D) printed structure). In some examples, a build piece may be manufactured such that the structural supports are internal to the completed build piece. However, removing the structural supports may reduce the weight of the build piece and reduce the amount of debris trapped within the build piece. Thus, certain aspects of the disclosure are directed to a hose including a bendable and elongated tube member as well as a fracturing member configured to fracture an internal support structure within an additively manufactured part.

Abstract

In various aspects, 3D printers, and sensor systems coupled to or integrated with the 3D printers are disclosed. The sensor systems may include image and second sensors for detecting potential defects or print artifacts. During printing, an energy beam source forms a weld pool by melting selected regions of print material, which solidifies to produce the build piece. The image sensor may image an area including the weld pool to determine a landing location of matter ejected during the heating of print material to form the weld pool. The second sensor may detect a defect in the build piece based on the determination of the landing location. Print operation may be suspended while the sensor data is used to repair the defect, after which 3D printing resumes. In this way, for example, high quality build pieces can be produced with reduced post-processing times, and hence a higher manufacturing throughput.

Abstract

Techniques for dehumidifying powder used as print material in a powder bed fusion (PBF) three-dimensional (3-D) system are disclosed. A hopper includes one or more ultrasonic transducers (UTs) positioned at strategic locations. When activated, the UTs use sound pressure at ultrasonic frequencies to agitate the powder particles held in the hopper.

In various embodiments, the desiccants may be supported by desiccators suspended in the powder, such as via the casing of the hopper. In other embodiments, the desiccants may be desiccant bags provided in a desiccant insert. The moisture accumulates in the desiccants. Among other advantages, no separate thermal source is needed to dry the powder, which can be provided directly to the PBF 3-D system via the re-coater for depositing layers to form a build piece.

Abstract

Self-supporting 3-D printed chassis structures are disclosed. Self-supporting ribs are selectively printed to walls of the structure to meet desired dynamic stiffness targets while maintaining a reduced mass. The self-supporting ribs can be used as both support structures (e.g., for outer walls) during 3-D printing and as stiffening structures when the chassis structure is in operation. In an embodiment, the chassis structure is printed such that no support structures are needed. Topology optimization can enable remaining unneeded internal ribs or supports to be removed, and a high inner spatial volume between ribs can be maintained to make maximum use of the part. In various embodiments, wall thicknesses can be maintained at or below 1-2 millimeters, which further reduces mass.

Abstract

Techniques for pre-heating the powders of layer deposited on the powder bed during a 3-D print process conducted by a 3-D printer are disclosed. A re-coater includes a heat source that pre-heats the deposited layer as a leveling member of the re-coater smooths the layer onto the powder bed. In some embodiments, the re-coater reheats the powder bed following the selective fusing of a layer by an energy beam source. The consistent pre-heating and re-heating of the powder directly on the surface of the powder bed maximally reduces damage, cracks, dimensional flaws, and other artifacts created by excessive thermal gradients in the case where heat is not used.

Abstract

3-D build jobs having surrogate supports, 3-D printers using surrogate supports, and techniques to support vulnerable regions of build pieces using surrogate supports are disclosed. The surrogate supports are generated in a first material configuration and are offset via a gap from the vulnerable regions. The gap comprises a second material configuration, such as loose or partially fused powder on which the build piece can be supported during 3-D printing. In alternative embodiments, the gap instead includes thin manual ties or a solid body using material that is stronger but more amenable to breaking off without damaging the build piece. Post-processing steps are dramatically reduced as the surrogate supports and gaps facilitate virtually error-free separation from the build piece. In an embodiment, the surrogate supports include a support structure extending to a fixed base underneath, the fixed base being a build plate or a global surrogate.

Abstract

A node to panel interface structure for use in a transport structure such as a vehicle is disclosed. In an aspect, the node includes a base, first and second sides protruding from the base to form a recess for receiving a panel, ports for adhesive injection and/or vacuum generation, one or more adhesive regions disposed on a surface of each side adjacent the panel, and at least one channel coupled between the first and second ports and configured to fill the adhesive regions with an adhesive, the adhesive being cured to form a node-panel interface. The node may be additively manufactured. In an exemplary embodiment, the node may use sealant features for including sealants that border and define the adhesive regions, and that may hermetically seal the region before and after adhesive injection. In another embodiment, the node may include isolation features for including isolators for inhibiting galvanic corrosion. In another aspect, adhesive may be filled serially on the adhesive regions on the first side and then on the adhesive regions on the second side. Adhesive may alternatively may be filled in parallel, or concurrently, on the adhesive regions of both sides.

Abstract

A dual-mode suspension system using hydraulic dampers is disclosed. One or more dampers on each side of the four-wheel suspension system are coupled to a respective damper on the other side via a damper valve. One or more leaf springs may be arranged between the leading links coupled to some of the dampers, and trailing links coupled to other of the dampers. The suspension system may advantageously engage, lock, or partially disengage the respective dampers connected by the valve on each side of the system. Manipulating the valve to control engagement of the dampers, which may depend on the speed and related issues, provides control over whether heave motions should be separated from roll. In another embodiment, one or more single or double acting hydraulic cylinders may be used to engage dampers.

Abstract

A high precision Interface Node is disclosed. The Interface Node includes an integrated structure including one or more complex or sophisticated features and functions. The Interface Node may connect with another component or a Linking Node. The Interface Node is manufactured to achieve high precision functionality while enabling volume production. Current additive manufacturing technologies allow for the printing of high precision features to be manufactured, but generally this is performed at a slower rate. Consequently, in one aspect, the size of the Interface Nodes is reduced in order to overcome at least part of the slower production volume caused by creating the high precision Interface Nodes. The components and Linking Nodes to which the Interface Node is connected may only have basic features and functions. Accordingly, this latter category of components may use a high print rate and thus high production volume. In other embodiments, these low precision components may also be produced using a non-print manufacturing technology, such as casting, forging, etc., that may provide the requisite high throughput, or to high precision machined parts that lack the geometric flexibility of the Interface Node. In an embodiment, the Interface Nodes may be connected to other components via a Linking Node.
