METHODS FOR PRODUCING ADDITIVELY MANUFACTURED OBJECTS WITH HETEROGENEOUS PROPERTIES
Methods for manufacturing objects are provided herein. In some embodiments, a method includes receiving a digital data set representing an object, and applying energy to a curable material based on the digital data set to form the object. The object can include at least two object portions formed from the curable material using different energy application parameters. The method can further include removing residual curable material from the object. A different amount of the residual curable material can be removed from each of the at least two object portions. After the residual curable material is removed, the at least two object portions can each have different material properties.
METHODS FOR SELECTIVE POST-CURING OF ADDITIVELY MANUFACTURED OBJECTS
Methods for manufacturing objects are provided herein. In some embodiments, a method includes receiving a dental appliance formed using an additive manufacturing process, the dental appliance including a plurality of appliance portions. The method can include identifying, based on sensor data, a location of a subset of the appliance portions on the dental appliance. The method can further include applying energy to a subset of the appliance portions to selectively modify one or more material properties of the subset of the appliance portions.
Curing-device
According to an embodiment, disclosed is a curing-device comprising: a stage; a light emitting module including a substrate disposed on the stage and a plurality of light emitting elements disposed on the substrate; and a plurality of transparent blocks disposed between the light emitting module and the stage, wherein the substrate includes a plurality of first sections and a plurality of second sections which are disposed in a first direction, the intervals in the first direction between the light emitting elements disposed in the first sections is smaller than the intervals in the first direction between the light emitting elements disposed in the second sections, and the plurality of transparent blocks are disposed on the first sections.
System for manufacturing thermoplastic parts
A system for manufacturing a thermoplastic part from a blank part having a first moulding member and a second moulding member which are configured to cooperate together. A first heating body configured to heat the first moulding member and conductively heat the blank part. Two thermal insulation members are configured to cooperatively define a closed cavity in which at least the moulding members and the first heating body are arranged. A casing defining an internal volume in which at least the moulding members, the first heating body and the thermal insulation members are arranged, and a suction member is configured to lower the internal pressure in the internal volume to compress the preform part between the moulding members.
MANUFACTURING METHOD OF RESIN ARTICLES
A manufacturing method of a resin article having a plurality of filamentous projections that are formed in a contact surface of a resin article body may include a thrusting step to thrust acute-angled leading edges of plate-shaped metal parts into the contact surface of the resin article body, a heating step to heat the plate-shaped metal parts before or during the thrusting step, and a pulling out step to pull out the plate-shaped metal parts in a condition in which portions of the resin material of the resin article body is melted around the leading edges of the plate-shaped metal parts and in which melted resin portions are formed on unmelted portions of the resin material of the resin article body.
Thermal curing of cell-based structural arrays
Cells of a composite cell array are cured by placing tool blocks in the cells and inserting thermally conductive elements in each of the tool blocks. The thermally conductive elements are convectively heated by a flow of hot air. The heated conductive elements conduct heat to the tooling blocks, which then conduct heat to the cells to cure the composite and adhesive.
PULSED LIGHT SYSTEM
An apparatus for manufacturing a composite article from a composite material. The apparatus comprising: a pulsed broadband radiation source comprising a flashlamp and a light guide adapted to guide light emitted by the pulsed broadband radiation source to a target area. The light guide comprises at least a portion ahead of the pulsed broadband radiation source, relative to the target area, comprising a light transmitting material.
THERMALLY EXPANDABLE SHEET
A thermally expandable sheet includes a base, a thermally expansive layer, and a color adjustment layer. The thermally expansive layer is provided on a first side of the base and includes a thermally expandable material that distends in accordance with an amount of heat absorbed, the heat being generated from a thermal conversion layer that includes a thermal conversion material that converts electromagnetic waves to heat. The color adjustment layer is provided on at least one of the thermally expansive layer and a second side of the base and includes a color adjusting agent. When the thermal conversion layer is provided on the color adjustment layer, the color adjustment layer reduces a visual difference in color between a first region where the thermal conversion layer is provided and a second region where the thermal conversion layer is not provided.
Three-dimensional article and method of making the same
Three-dimensional polymeric article (100) having first (101) and second (102) opposed major surfaces, a first dimension perpendicular to a second dimension, a thickness orthogonal to the first and second dimensions, and a plurality of alternating first (107) and second (109) polymeric regions along the first or second dimensions, wherein the first (107) and second (108) regions extend at least partially across the second dimension, wherein the first regions (107) are in a common plane (115) and wherein some of the second regions (108) project outwardly from the plane (115) in a first direction (generally perpendicular from the plane), and some of the second regions (108) project outwardly from the plane (115) in a second direction that is generally 180 degrees from the first direction, where the first regions (107) have a first crosslink density, wherein the second regions (108) have a second crosslink density, and wherein the second crosslink density of the second regions (108) are less than the first crosslink density of the first regions (107). Embodiments of the articles are useful for example, for providing a dual-sided, textured wrapping film such that greater grip is realized both on an item wrapped by the film and the wrapped item itself.
MOLD WITH THERMALLY CONDUCTIVE FLANGES
A mold for forming a flange of a wind turbine blade comprising a first flange portion including a plurality of lamina and having a generally planar shape and a second perpendicular flange including a plurality of lamina. A plurality of copper wires are disposed within the lamina for conducting heat delivered from a base portion through the first and second flange portions. The mold is free of fluid conduits with the flange portions moveable relative to the base portion.
