摘要： An additive manufacturing method. The method includes mixing a reflective material including fibers with a photopolymer resin to form a resin mixture having a loading of the reflective material of at least 3 wt. %. The method further includes curing the resin mixture using a light source to form first and second individually cured layers and a bridge of a portion of the fibers between the two layers.

摘要： A thermoset resin for forming parts to be metal plated includes a vat photopolymerization (VPP) thermoset resin and an etchable phase disposed in the VPP thermoset resin. The etchable phase is etched from a surface of a part formed from the VPP thermoset resin such that a plurality of micro-mechanical locking sites is formed on the surface of the part. The etchable phase is at least one of organic particles, organic resins, inorganic particles, and copolymers of the VPP thermoset resin. For example, the etchable phase can be a polybutadiene phase and/or a mineral such as calcium carbonate.

摘要： A bio-based polyol-containing polymer foam material, which includes a bio-based polyol-containing polymer foam present in a bulk concentration of the bio-based polymer foam material of 99% by weight or greater; and a graphite material present in a bulk concentration of the bio-based polyol-containing polymer foam material of 1% by weight or less. The bio-based polyol-containing polymer foam material is especially suitable for automotive components having deadening and vibration management features.

摘要： Articles, methods of making an article, and resin compositions are disclosed. An article is disclosed that includes a cured light-curable resin having dispersed therein a reflective material that reflects at least 85% of the visible light spectrum. A loading of reflective material may be at least 3 wt. % of the article and the reflective material may comprise over 50 vol. % of a total filler composition of the article. The reflective material may be a white or near-white material, such as cellulose fibers, talc powder, or soy flour. A method is disclosed that includes mixing a reflective material that reflects at least 85% of the visible light spectrum with a photopolymer resin at a loading of at least 3 wt. % to form a resin mixture and curing the resin mixture using a light source in an additive manufacturing process. The disclosed resins may reduce the curing time of additive manufacturing processes.

摘要： A method of forming an etched part includes forming a substrate including a thermoset resin and etching a surface of the substrate. The thermoset resin includes a vat photopolymerization (VPP) thermoset resin and at least one of an etchable phase and etchable particles disposed within the VPP thermoset resin. The etching removes the etchable phase from the VPP thermoset resin at the surface of the substrate such that a plurality of micro-mechanical bonding sites are formed on an etched surface of the substrate.

摘要： A method of additive manufacturing a part via vat photopolymerization (VPP) includes irradiating a first material through a first transparent wall of a first material tank and forming a first section of an nth layer of the part on a platform, positioning the platform with the first section of the nth layer in a second material tank with a distance between the first section of the nth layer and a second transparent wall, and irradiating a second material such that a second section of the nth layer of the part is formed on the platform adjacent to the first section of the nth layer. The method repeats forming first and second sections of additional layer until a predetermined number of total layers are formed. Positioning the first and second sections with a distance between the second and first transparent walls, respectively, inhibits crashing during forming of the part.

摘要： A method of forming a part includes 3D printing a photopolymerizable resin and forming a preformed part and subsequently post-curing the preformed part with electron beams. The preformed part may be cured via UV curing. A section of the preformed part post-cured with electron beams may have a thickness of at least 1.0 centimeter, for example, at least 2.0 centimeters or at least 3.0 centimeters. An electron beam dosage to post-cure the preformed part may be between 10 kilogray (kGy) and 100 kGy. The preformed part may be 3D printed using stereolithography (SLA), digital light processing (DLP) or material jetting (MJ) and the photopolymerizable resin may include at least one of an acrylate functional polymer and a methacrylate functional polymer. In the alternative, or in addition to, the photopolymerizable resin may include at least one of a urethane, a polyester, and a polyether.
