An organic glass includes an acrylic plate, a methyl methacrylate layer, and a fluorescent bubble layer that are sequentially stacked; and the fluorescent bubble layer is prepared from fluorescent polymethyl methacrylate beads, a first methyl methacrylate prepolymer and a second methyl methacrylate prepolymer. The fluorescent polymethyl methacrylate beads added into the raw material of the organic glass have an expandable characteristic, and can generate bubbles according to a design pattern to achieve the purpose of controllable bubbles, and the added fluorescent polymethyl methacrylate beads show fluorescent green under ultraviolet irradiation, giving bubbles a fluorescent color, and enabling the organic glass to have extremely artistic and decorative effects.

An approach to improving optical scanning increases the strength of optical reflection from the build material during fabrication. In some examples, the approach makes use of an additive (or a combination of multiple additives) that increases the received signal strength and/or improves the received signal-to-noise ratio in optical scanning for industrial metrology. Elements not naturally present in the material are introduced in the additives in order to increase fluorescence, scattering or luminescence. Such additives may include one or more of: small molecules, polymers, peptides, proteins, metal or semiconductive nanoparticles, and silicate nanoparticles.

A method of manufacturing a radiation detector includes adding a fluorescing medium to an additive manufacturing consumable to form a consumable mixture; additively manufacturing a plastic scintillator from the consumable mixture; and coupling the plastic scintillator to a light-to-current device, thereby forming an additively manufactured plastic scintillation detector.

The invention pertains to the use of sophisticated chemical formulation and spectroscopic design methods to select taggants compatible with the 3D print medium that are easily detected spectroscopically but otherwise compatible with the product, structural integrity and stability, and aesthetics. A spectral pattern employs a different chemical or combination of chemicals to alter the formulation of all or some portion of the printed object so that its authenticity can be monitored later using a spectrometer.

Phosphor elements comprising phosphors in a host material having a phosphorescence-emitting surface with surface nanostructures are disclosed. Phosphor wheels having such phosphor elements, methods of making such phosphor elements, and methods of using such phosphor elements are also disclosed.

A method of forming a seatbelt buckle assembly comprises forming a housing by injection molding with a first mold cavity, allowing the injection molded housing to cool and cure, placing the housing into a second mold cavity, forming a debris shield by over-molding the debris shield directly onto portions of an outer surface of the housing within the second mold cavity, allowing the over-molded debris shield to cool and cure, and removing the housing with the over-molded debris shield from the second mold cavity.

Some examples include a computer-readable medium storing executable instructions which, when executed by a processor, are to cause the processor to receive electronic data describing a part to be manufactured in a three-dimensional additive manufacturing process; develop instructions using the electronic data for creating an outer layer on a surface of the part in the additive manufacturing process, where the outer layer having a physical property that differs from that of the surface of the part; and manufacture the part using the instructions.
