A plasma etching method using a Faraday cage which is capable of inhibiting the formation of a needle-like structure and forming a pattern portion having a depth gradient on an etching base.

A process of 3D scanning lactating women's breasts to generate an AutoCAD model of the maternal nipple is disclosed. The 3D scanning and generation of a plurality of maternal nipple shapes for creation of breastfeeding accessories and molds is intended to closely mimic a specific mother's unique nipple shape, which can vary widely from one woman to another. The embodiments eliminate nipple confusion in infants being introduced to a bottle nipple and pacifier, in order to promote prolonged breastfeeding. Mimicking a mother's unique nipple shape helps create accessories that better fit a mother's unique nipple size and shape and decrease pain (i.e. pump flange and nipple shield).

An example mandrel for processing a part is described including a plurality of elastomeric components aligned end to end and spaced apart linearly to form a segmented mandrel body, and compressible interconnections positioned within spacing between adjacent elastomeric components and abutting the adjacent elastomeric components. The compressible interconnections allow the plurality of elastomeric components to expand axially due to thermal expansion resulting in a distribution of pressure. An example method for fabricating a composite part is also described including placing a base composite layer into a cavity of a tooling surface, inserting a mandrel into the cavity of the tooling surface such that the base composite layer is between the mandrel and the tooling surface, applying a skin to the mandrel and the base composite layer forming a package, enclosing the package in a vacuum bag and curing, and removing the mandrel from the cavity of the tooling surface.

Process and mold embodiments are described herein for creating polyurethane molds that allow for the production of manhole bases.

Thermoset ceramic compositions and a method of preparation of such compositions. The compositions are advanced organic/inorganic hybrid composite polymer ceramic alloys. The material combines strength, hardness and high temperature performance of technical ceramics with the strength, ductility, thermal shock resistance, density, and easy processing of the polymer. Consisting of a branched backbone of silicon, and alumina, with highly coordinated Si—O—Si or Al—O—Al bonds, the material undergoes sintering at 7 to 300 centigrade for 2 to 94 hours from water at a pH between 0 to 14, humidity of 0 to 100%, with or without vaporous solvents.

A molded pot is provided with imperfections manufactured by manufacturing mold tooling with imperfections by obtaining a handmade pot. The handmade pot is scanned to obtain geometric data. The geometric data is converted to mold tooling geometric data. Mold tooling is manufactured from the mold tooling geometric data. The handmade pot is obtained with imperfections. The handmade pot is scanned to obtain the geometric data of the handmade pot with the imperfections. The geometric data is converted to mold tooling geometric data with the imperfections. The mold tooling is manufactured with imperfections. A pot is molded with imperfections from the mold tooling.

A formed article producing method, includes a first step of shaping a shaping body by ejecting a shaping material including a thermoplastic resin and of forming a first formed article by cutting the shaping body with a first rotating tool; a second step of generating recycling material by cutting the first formed article with a second rotating tool; and a third step of forming a second formed article by ejecting the recycling material that was plasticized, wherein in the second step, the first formed article is cut under at least one condition of a condition that a moving speed of the second rotating tool is faster than a moving speed of the first rotating tool in the first step or a condition that a rotating speed of the second rotating tool is slower than a rotating speed of the first rotating tool in the first step.

A prismatic mold having a molding surface having a floor and opposing sidewalls and at least one indentation in a three-dimensional shape of a distinguishing device, is described.

Embodiments of the present disclosure are drawn to additive manufacturing apparatus and methods. An exemplary additive manufacturing method may include forming a part using additive manufacturing. The method may also include bringing the part to a first temperature, measuring the part along at least three axes at the first temperature, bringing the part to a second temperature, different than the first temperature, and measuring the part along the at least three axes at the second temperature. The method may further include comparing the size of the part at the first and second temperatures to calculate a coefficient of thermal expansion, generating a tool path that compensates for the coefficient of thermal expansion, bringing the part to the first temperature, and trimming the part while the part is at the first temperature using the tool path.
