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.

A set including a plug connectable LED and a packaged photocurable composition. It relates also to methods for applying that article. The photocurable composition includes cyanoacrylate monomers and/or acrylate monomers, and a visible light photoinitiator system. The plug connectable LED, when connected to a host mobile device including a rechargeable battery, allows energisation of the LED so that it can be used as a convenient light source to cure the photocurable composition. The set itself does not comprise a battery or, batteries. The set is a versatile consumer product in the field of adhesives, fillers, sealants and coatings.

A post-exposure unit for post-exposure of a body manufactured using an additive manufacturing method from a substance curable by radiation, the post-exposure unit comprising at least one radiation source configured for post-exposure, the post-exposure unit including at least one radiation sensor, the radiation sensor being adapted to capture radiation emitted by the radiation source. The post-exposure unit has a receiving space for receiving a body to be post-exposed. The radiation sensor is adapted to capture radiation emitted by the radiation source and traverses at least a part of the receiving space at least once.

Continuous additive manufacturing apparatuses are provided. An apparatus includes an actinic radiation-transparent substrate having a major surface and an irradiation source configured to direct actinic radiation through the actinic radiation-transparent substrate at predetermined dosages at predetermined locations. The apparatus further includes a means for depositing a composition onto the major surface of the actinic radiation-transparent substrate and a means for conveying the actinic radiation-transparent substrate or the irradiation source with respect to each other.

A functional polymeric cutting edge structure and methods for manufacturing cutting edge structures using polymeric materials are provided. A razor blade for use in a razor cartridge or a blade box for assembly in a razor cartridge frame may be formed using the present invention.

The present disclosure relates generally to curable resins, in particular latent cure resins, and related methods for use in an additive fabrication (e.g., 3-dimensional printing) device.

A method of activating a surface of a plastics substrate formed from: (a) polyaryletherketone such as polyether ether ketone (PEEK) polyether ketone ketone (PEKK), polyether ketone (PEK); polyether ether ketone ketone (PEEKK); or polyether ketone ether ketone ketone (PEKEKK); (b) a polymer containing a phenyl group directly attached to a carbonyl group, optionally wherein the carbonyl group is part of an amide group, such as polyarylamide (PARA); (c) polyphenylene sulfide (PPS); or (d) polyetherimide (PEI); for subsequent bonding,
the method comprising the step of exposing the surface to actinic radiation wherein the actinic radiation: includes radiation with wavelength in the range from about 10 nm to about 1000 nm; the energy of the actinic radiation to which the surface is exposed is in the range from about 0.5 J/cm.sup.2 to about 300 J/cm.sup.2. Hard to bond substrates are then more easily subsequently bonded for example using acrylic, epoxy or anaerobic adhesive.

A curing apparatus for curing a coating composition disposed on an optical fiber, the curing apparatus including a first light source and a second light source such that the second light source is spaced from the first light with a gap. The curing apparatus further including a first reflector and a second reflector such that the second reflector is spaced from the first reflector with the gap. Furthermore, a spacer is disposed within the gap, the spacer being formed of a material configured to reflect at least about 90% of light emitted from the first light source and from the second light source, and incident on the spacer, to an optical fiber such that the reflected light has sufficient intensity to cure a coating on the optical fiber.

Provided herein according to some embodiments is a method of forming a three-dimensional intermediate object with a polymerizable liquid, said polymerizable liquid comprising a mixture of (i) a microwave absorbing material, (ii) a light polymerizable liquid first component, and (iii) a second solidifiable component that is different from said first component. Optionally, but in some embodiments preferably, the method includes supporting the three-dimensional intermediate with a separate support media prior to solidifying and/or curing the second solidifiable component in the three-dimensional intermediate to form the three-dimensional object; and then optionally separating said support media when present from said three-dimensional object.

Methods of using and repairing seal caps as well as constructions comprising seal caps, including in some embodiments seal caps which may be useful in sealing fasteners that protrude into fuel storage cells in aircraft. In some embodiments, methods include the use of optically translucent seal cap and application of a second quantity of sealant to fill voids observed within the interior of the seal cap after cure of a first quantity of sealant.
