CPC Class B33Y

An orthopedic surgical instrument includes from about 40 wt % to about 85 wt % of a base thermoplastic and from about 15 wt % to about 60 wt % of a filler material. The base thermoplastic includes polyetherimide, polycarbonate, modified polyphenylene ether, polyamide, copolymers of these thermoplastics, and combinations thereof. In some aspects all materials in the orthopedic surgical instrument are biocompatible. An orthopedic surgical kit includes an orthopedic surgical instrument and a container suitable for sealing the orthopedic surgical instrument therein. The orthopedic surgical instrument in the kit includes from about 50 wt % to about 90 wt % of a base thermoplastic selected from the group consisting of polyetherimide, polycarbonate, modified polyphenylene ether, polyamide, copolymers of these thermoplastics, and combinations thereof, and from about 10 wt % to about 50 wt % of a filler material.

A bionic apparatus is provided. The bionic apparatus includes a flexible portion having a plurality of pores, a rigid portion connected with the flexible portion, and a supporting element disposed in the flexible portion. The pore size of each pore is between 50 μm to 500 μm. The flexible portion, the rigid portion and the supporting element are one-piece formed by a additive manufacturing process.

There is disclosed a method for manufacturing a denture comprising an artificial gingiva surface, a seating surface facing at least a part of the gingiva surface when placed in the mouth of a patient, at least one tooth receiving hole provided in the artificial gingiva surface and extending through to the seating surface and an artificial tooth arranged in the tooth receiving hole, The method comprises printing an intermediate denture base comprising the artificial gingiva surface, the at least one tooth receiving hole for receiving the artificial tooth, arranging the artificial tooth in the at least one tooth receiving hole, fixing the intermediate denture base in a milling machine, and milling the denture comprising providing the seating surface by removing at least a part of the tooth extending through the tooth receiving hole. This provides an improved manufacturing process of denture.

A composition includes a light-curable viscous mixture that includes: 0-50% by weight of a poly(methyl methacrylate)/methyl methacrylate solution; 5-20% by weight of at least one kind of multifunctional aliphatic (meth)acrylate; 5-40% by weight of at least one kind of aliphatic urethane (meth)acrylate oligomer; 25-65% by weight of at least one kind of difunctional bisphenol-A dimethacrylate; 0.1 to 5% by weight of at least one kind of a photoinitiator; 0.05 to 2% by weight of at least one kind of light stabilizer; and 0.1 to 3% by weight of color pigment based on the total weight of the composition.

The invention relates to a method for producing a cast component which has cavity structures, using a 3D pattern of digital geometrical coordinates of the cast component by means of a ceramic mold, said method comprising the use of CNC technology.

A method and apparatus for printing on an article are disclosed. An embodiment of a method may include the generation of a virtual mask that can designate areas for printing and/or designate areas to exclude from printing. A method may include utilization of the virtual mask during either 2D or 3D printing such that a print design is printed in areas designated for printing by the virtual mask.
