An artificial structure for promoting microalgae growth includes a 3D-printed structure formed by positioning a printing surface on a movable stage of a 3D bioprinter in contact with a bio-ink that includes a mixture of a pre-polymer material with one or more of cellulose-derived nanocrystals (CNC), and microalgae cells. By projecting modulated light onto the printing surface while moving the stage, the bio-ink is progressively polymerized to define layers of an artificial coral structure with microalgae cells disposed thereon, where the artificial coral structure is configured to scatter light within the structure.

A method for fabricating a wildlife reproduction includes placing a reference device relative to a wildlife subject. The reference device pertains to scale and chromaticity coordinates to provide an accurate size and color reference for fabricating the wildlife reproduction of the wildlife subject. The wildlife subject is photographed in combination with the reference device at one or more predefined locations to produce two dimensional photographic image data. The two dimensional image data is converted to a three dimensional image file using photogrammetry. A value of the principal dimension of the wildlife subject is determined using the reference device. Dimensions of at least one other feature of the wildlife subject are calculated from the principal dimension to modify a three-dimensional image file of a selected wildlife subject to correspond to the wildlife subject. A three dimensional wildlife reproduction is fabricated from the modified three-dimensional image file of the selected wildlife subject.

Implementations of an artificial nail measurement system and method (artificial nail measurement) are provided. In some implementations, the artificial nail measurement may comprise a mold casting kit. In some implementations, the artificial nail measurement may further comprise a mold extraction kit. In some implementations, a method for the artificial nail measurement comprises a user receiving and using a mold casting kit to form a mold of the user's fingernails, shipping the mold to a nail technician to form a cast or replica of the user's fingernails, and the nail technician using the cast to measure the user's fingernails to select from pre-made artificial nails that then designed and shipped to the user for use.
