A method and system for constructing an architectural component from a three-dimensional form, the system including a movable support table for supporting and moving a three-dimensional form, a multi-task robotic arm having a base end configured for controlled movement along a path proximate the support table and a distal end configured to extend, translate, and/or rotate relative to the base and to include an end effector for applying successive layers of material onto a form on the support table, optionally, a linear rail to which said base is attached, and a computer processor for controlling a sequence of movements of the support table, the base, and the distal end of said multi-task robotic arm, and for controlling application of material to the three-diniensional form to form an architectural component of a predetermined shape and dimension.

A system and method for processing a flexible part comprising holding the flexible part securely in an unconstrained position using a holder; and controlling a positioner to process the flexible part based on a comparison of a shape and/or position of the flexible part in the unconstrained position with design specifications of the part not in the unconstrained position.

One example includes a three-dimensional (3D) printed object including a first lattice structure and a second lattice structure. The first lattice structure includes a first matrix having a first length, a first width, and a first height. The second lattice structure includes a second matrix having a second length, a second width, and a second height. The second length times two is a factor of the first length, the second width times two is a factor of the first width, and the second height times two is a factor of the first height.

A method for forming a press connection between a first component and a second component such that force is transmissible between the first component and the second component. A portion of the first component is oversized relative to a portion of the second component, and the portion of second component is configured to receive the portion of the first component. The method includes applying an adhesive to the portion of the first component and/or to the portion of the second component, the adhesive in an uncured state being configured to reduce a coefficient of friction between the portion of the first component and/or the portion of the second component, pressing the portion of the first component into the portion of the second component to form a press connection, and curing the adhesive or allowing the adhesive to cure.

Provided is a compression molding die. The die can be used for compression molding an I-shaped part without the need for machining. The molding die comprises: an outer mold with an inner diameter of d; an upper pressing disc, a lower pressing disc and a huff mold with the same outer diameter of d and the same inner diameter of f; an upper mold; a lower mold; and a core mold with a diameter of h. The upper pressing disc, the huff mold and the lower pressing disc, which are movable vertically, are arranged in the outer mold in a vertically spaced manner; the vertically movable upper mold extends into the upper pressing disc, and the vertically movable lower mold extends into the lower pressing disc; the outer mold, the upper mold, the upper pressing disc, the huff mold, the lower pressing disc and the lower mold define a cavity.

A method for fabricating a part by selective melting or sintering of powder beds by high energy beam, the method including a) providing a material in the form of powder particles; b) depositing a first powder layer on a support; c) scanning a region of the first layer with the beam to heat the powder locally to a temperature higher than the powder sintering temperature, such that the powder particles as melted or sintered form a first single-piece element; d) depositing a second powder layer on the first powder layer; e) scanning a region of the second layer with the beam to heat the powder to a temperature higher than the powder sintering temperature, so that the particles of powder as sintered or melted form a second single-piece element; and f) repeating d) and e) for each new powder layer laid over a preceding layer until the part is formed.

A method of making a part includes the steps of: securing a build platform to an actuator which is disposed in a build chamber, depositing a powder onto the build platform; directing a beam from a directed energy source to fuse the powder; moving the actuator vertically downward within the build chamber by a layer increment of powder; repeating in a cycle the steps of depositing, directing, and moving to build up the part in a layer-by-layer fashion until the part is complete; lifting the build platform away from the actuator to create an opening therebetween; and evacuating the powder from the build chamber through the opening.

Methods and systems for designing and manufacturing a mathematically fair N-sided die are disclosed. An example method can comprise selecting an irregular polyhedron to serve as a die, and determining a center of mass of the selected irregular polyhedron die. In an aspect, a size of each face of the irregular polyhedron can be selected such that a solid angle subtended by each face from the center of mass of the selected irregular polyhedron can be equal. In an aspect a system comprising an injection molding apparatus can be used to form the die.
