Abstract: A continuous method of manufacturing adhesives is provided. The method includes obtaining an actinic radiation-polymerizable adhesive precursor composition disposed on a major surface of an actinic radiation-transparent substrate and irradiating a first portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate for a first irradiation dosage. The method further includes moving the actinic radiation-transparent substrate and irradiating a second portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate for a second irradiation dosage. Optionally, the method also includes irradiating a third portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate prior to moving the substrate. The first irradiation dosage and the third irradiation dosage are often not the same, thereby forming an integral adhesive having a variable thickness in an axis normal to the actinic radiation-transparent substrate.

Abstract: The present disclosure provides methods of making a vitreous bond abrasive article and a metal bond abrasive article. An abrasive article preform is produced by an additive manufacturing sub-process comprising the deposition of a layer of loose powder particles in a confined region and selective heating via conduction or irradiation to heat treat an area of the layer of loose powder particles. The loose powder particles include abrasive particles and organic compound particles, as well as vitreous bond precursor particles or metal particles. The abrasive article preform produced by additive manufacturing is subsequently heated to provide the vitreous bond abrasive article comprising the abrasive particles retained in a vitreous bond material, or to provide the metal bond abrasive article. Also, the methods include receiving, by an additive manufacturing device having a processor, a digital object specifying data for an abrasive article, and generating the abrasive article with the manufacturing device.

Abstract: The method of making a three-dimensional article includes heating a composition comprising a polymer and hollow ceramic microspheres, extruding the composition in molten form from an extrusion head to provide at least a portion of a first layer of the three-dimensional article, and extruding at least a second layer of the composition in molten form from the extrusion head onto at least the portion of the first layer to make at least a portion of the three-dimensional article. Three-dimensional articles are also described. A composition including a polymer and hollow ceramic microspheres is also described. The composition may be a filament. The polymer is at least one of a low-surface-energy polymer or polyolefin. The composition can be useful, for example, in melt extrusion additive manufacturing, for example, fused filament fabrication.

Abstract: The present disclosure provides a method for building a three-dimensional object using a printable composition including high viscosity polymerizable components. The method includes the steps of a) providing a printable composition comprising a high viscosity polymerizable component and a temporary solvent; b) selectively curing the printable composition to form an article representing the shape of the three-dimensional object; and c) removing a substantial amount of the temporary solvent from the article. The method is particularly well suited to making an orthodontic clear tray aligner. Also disclosed are a variety of printable compositions including high viscosity polymerizable components, such as polyurethane methacrylates, and temporary solvents.

Abstract: The present disclosure provides methods of making a vitreous bond abrasive article and a metal bond abrasive article. The methods include sequential steps. Step a) includes a subprocess including sequentially: i) depositing a layer of loose powder particles in a confined region; and ii) selectively applying heat via conduction or irradiation, to heat treat an area of the layer of loose powder particles. The loose powder particles include abrasive particles and organic compound particles, as well as vitreous bond precursor particles or metal particles. The layer of loose powder particles has substantially uniform thickness. Step b) includes independently carrying out step a) a number of times to generate an abrasive article preform comprising the bonded powder particles and remaining loose powder particles. Step c) includes separating remaining loose powder particles from the abrasive article preform. Step d) includes heating the abrasive article preform to provide the vitreous bond abrasive article comprising the abrasive particles retained in a vitreous bond material, or to provide the metal bond abrasive article. A method of making a metal bond abrasive optionally includes infusing an abrasive article preform with a molten lower melting metal and solidifying the molten lower melting metal to provide the metal bond abrasive article. The present disclosure further provides a vitreous bond abrasive article precursor and a metal bond abrasive article precursor.

Abstract: A method of making an adhesive is provided, including obtaining an actinic radiation-polymerizable adhesive precursor composition disposed against a surface of an actinic radiation-transparent substrate and irradiating a first portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate for a first irradiation dosage. The method further includes irradiating a second portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate for a second irradiation dosage. The first portion and the second portion are adjacent to or overlapping with each other and the first irradiation dosage and the second irradiation dosage are not the same. The method forms an integral adhesive having a variable thickness in an axis normal to the surface of the actinic radiation-transparent substrate. Also, an adhesive article is provided, including a substrate having a major surface and an integral adhesive disposed on the major surface of the substrate. Further, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying an article; and generating, with the manufacturing device by an additive manufacturing process, the article based on the digital object. A system is provided, including a display that displays a 3D model of an article; and one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of an article.
