摘要： An example system for molding a photocurable material into a planar object includes a first mold structure having a first mold surface, a second mold structure having a second mold surface, and one or more protrusions disposed along at least one of the first mold surface or the second mold surface. During operation, the system is configured to position the first and second mold structures such that the first and second mold surfaces face each other with the one or more protrusions contacting the opposite mold surface, and a volume having a total thickness variation (TTV) of 500 nm or less is defined between the first and second mold surfaces. The system is further configured to receive the photocurable material in the volume, and direct radiation at the one or more wavelengths into the volume.

摘要： A method for manufacturing shaped polymers of surface-active macromolecules, in particular silk, is provided. The method is comprising the steps of: • a) depositing an aqueous solution of the surface-active macromolecules on a surface, wherein the aqueous solution of the surface-active macromolecules is deposited in the form of a droplet, and wherein the surface is a hydrophobic micropatterned surface adapted to prevent the aqueous solution from penetrating into the pattern and to receive the droplet of the aqueous solution of the surface-active macromolecules and retain its droplet state; and • b) forming shaped polymers of the surface-active macromolecules on the surface.

摘要： Embodiments of the present invention relates to an acoustic metamaterial, as well as to a method for manufacturing the same. The acoustic metamaterial includes a plurality of channels or columns each having the same cross-section with a hydraulic radius between 5 and 300 μm, which channels or columns are arranged with a periodic spacing between 2 and 600 μm. This results in a highly dense network that can provide optimal acoustic absorption and/or impedance over a wide frequency range. The method for manufacturing the same includes additive manufacturing with a plurality of consecutive material deposition steps to form, in each step, a layer comprising a plurality of periodically repeated cells separated by walls. The layers deposited in the consecutive material deposition steps are stacked with their respective cells aligned to form channels.

摘要： Methods of forming dental appliances. The methods may include partially curing a prepolymer mixture in a first mold to form a partially cured polymer mixture. The first mold may have an internal cavity that is shaped to provide the partially cured polymer mixture with a first shape having a channel in accordance with a dental arch. The first shape may have a greater thickness at locations corresponding to where a gingival line of the dental appliance will be formed compared to a thickness at occlusal surfaces of the dental appliance. The methods may include modifying the first shape of the partially cured polymer mixture to form a shell having cavities shaped to receive teeth. The methods may also include fully curing the shell by exposing the partially cured polymer mixture to energy until the partially cured polymer mixture thermosets.

摘要： A simulated abdominal wall model that is ideal for practicing laparoscopic first entry surgical techniques is provided. The model includes a simulated abdominal wall portion captured between two frame elements of a support. The support is connectable to a surgical trainer. When connected to the trainer, the model provides a penetrable abdominal tissue portion for accessing an internal cavity of the trainer. The simulated abdominal wall includes a plurality of layers including a skin layer, a fabric posterior rectus sheath layer, a simulated fat layer of low-resilience polyurethane foam and at least two layers that provide distinctive haptic feedback upon penetration of the simulated transversalis fascia and muscle layers. The simulated abdominal wall includes a simulated umbilicus across several layers of simulated tissue.

摘要： A novel cutting-edge structure and method and apparatus for manufacturing the cutting-edge structure is provided. The cutting-edge structure is comprised of naturally derived or renewable material at greater than 50% by volume fraction. In one embodiment, the naturally derived material is a cellulose nanostructure such as a cellulose nanocrystal. The cellulose nanocrystal is processed using a base or mold structure to provide a cutting edge of any shape such as linear or circular edge structures. The process includes dual cure steps to produce an optimal cutting-edge structure without shrinkage. The formed cutting-edge structure can be utilized as a razor blade as it is formed with very sharp tip and edge suitable for cutting hair. The base structure can form one or more cutting-edge structures simultaneously.

摘要： Provided are an anti-wrinkle composition, an anti-wrinkle microneedle patch and a preparation method thereof. The anti-wrinkle microneedle patch comprises a base and multiple needles, the base has an upper surface, and the needles are formed on the upper surface; wherein, a material of each needle comprises a low-molecular hyaluronic acid, a modified hyaluronic acid and a cross-linked hyaluronic acid. A weight ratio of the modified hyaluronic acid to the low-molecular hyaluronic acid is 0.1 to 4, and a weight ratio of the modified hyaluronic acid to the cross-linked hyaluronic acid is less than 30. Accordingly, the anti-wrinkle microneedle patch has effects of moisturizing the skin, elevating the thickness and the strength of the skin, and smoothing and reducing the wrinkles.
