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).

Embodiments relate to an aligner breakage solution. A method includes obtaining a digital design of a polymeric aligner for a dental arch of a patient. The polymeric aligner is shaped to apply forces to teeth of the dental arch. The method also includes performing an analysis on the digital design of the polymeric aligner using at least one of a) a trained machine learning model, b) a numerical simulation, c) a geometry evaluator or d) a rules engine. The method may also include determining, based on the analysis, whether the digital design of the polymeric aligner includes probable points of damage, wherein for a probable point of damage there is a threshold probability that breakage, deformation, or warpage will occur. The method may also include, responsive to determining that the digital design of the polymeric aligner comprises probable points of damage, performing corrective actions based on the probable points of damage.

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.

The present disclosure provides a method of adjusting a dimension of a molded product. The method includes generating a plurality of adjusted molding conditions comprising an adjusted velocity profile and an adjusted packing pressure profile; conducting, via an injection-molding apparatus, an actual molding to produce a molded product using the adjusted molding conditions if the adjusted molding condition is qualified; determining whether a dimension of the molded product needs to be adjusted; and updating at least one of the adjusted molding conditions if the dimension of the molded product needs to be adjusted.

Systems and methods for manufacturing a wavefront-customized contact lens. The systems include: (1) an optical instrument for measuring ocular imperfections of a patient's eye; (2) a computer for designing a mold and pin design used for manufacturing a wavefront-customized contact lens that corrects the ocular imperfections; (3) a fabrication machine for fabricating a wavefront-customized mold that includes corrections for the ocular imperfections; and (4) a manufacturing equipment for manufacturing a wavefront-customized contact lenses that uses the wavefront-customized mold; wherein the wavefront-customized mold design and wavefront-guided contact lens manufacturing are uniquely customized for each patient's eye. The optical means can be a wavefront aberrometer with, or without, a profilometer and/or an Optical Coherence Tomography (OCT) module. The wavefront-customized contact lens can be a soft contact lens or a rigid, gas permeable contact lens.

Creating a replica of an anatomical structure. In one embodiments a method includes: accepting pictures of the anatomical structure of a subject; creating an object file that contains an initial model of an outside surface of the anatomical structure; cutting the initial model to a predetermined exterior shape circumscribing the anatomical structure to create a positive model; creating a negative model from the positive model; placing a stem tool object on an outside surface of the negative model in relationship to an orifice, thereby creating a final negative model; placing a zeroing and angling object to align the negative model to a predetermined angle; placing a base tool object by coupling the base tool object to the outside surface; printing, by way of a three-dimensional printer, the final negative model to create a negative mold; and casting the replica of the anatomical structure using the negative mold.

A method for making dies for die casting, and relative die, includes designing moulding parts of the die as plurality of sub-inserts. Each sub-insert of the plurality is bordered by boundary lines defined on the basis of a simulation of thermo mechanical behaviour of the die in operation. The simulation is performed by a processor of a computer and the behaviour is the behaviour of the die if the die were a single piece. The method also includes producing the plurality of sub-inserts and assembling the sub-inserts of the plurality with attachment means, so as to form the die.

The invention relates to a method for computationally designing re-usable silicone molds for the reproduction of an object, wherein the silicone mold is fillable with casting material, for example, but not limited to, resin, to form the object.

The present invention relates to a method of manufacturing a dental component, in particular a dental prosthesis or a partial dental prosthesis, by means of a dental furnace, comprising the following steps: (i) additively manufacturing, in particular by means of 3D printing, a model of the dental component from a model material on the basis of a virtual 3D model of the dental component; (ii) embedding the model in an investment material; (iii) removing the model from the investment material, in particular by heating or burning out, to obtain a negative mold of the model; (iv) inserting a raw material required for manufacturing the dental component into the negative mold; (v) producing the dental component in the negative mold; and (vi) removing the negative mold.

A method employs a first polymeric material to deposit first and second pattern layers laterally shifted from each other such that laterally shifted pattern layers form between them an empty volume with a variable cross-section that varies along with the first and second pattern layers. A second polymeric material is cast in the empty volume between the first and second pattern layers to cast a complex-shaped 3D object identical in shape to the empty volume between the first and second pattern layers. Radiation is applied to cure the first and second polymeric materials. The first polymeric material is a water breakable material composition including acrylamide, methacrylamide, acrylate, acrylic acids, and acrylic acid salts, hydroxy(meth)acrylate, carboxy(meth)acrylate, acrylonitrile, carbohydrate monomers, methacrylate and polyfunctional acrylics.
