Title: Modular system for customized orthodontic appliance
Applicant(s): Top Service Fuer Lingualtechni
Patent number: JP2010042267 (A)
Publication date: 25 February 2010
Problem to be solved: to provide a method for designing and manufacturing an orthodontic bracket customized for a patient with a computer. SOLUTION: a set of customized orthodontic brackets includes slots that are arranged substantially parallel to the tooth surface. An archwire, in an as-manufactured condition, has a region of a substantial arcuate extent, which is canted relative to the occlusal plane. The brackets are designed on a computer as a combination of three-dimensional virtual objects comprising a virtual bracket bonding pad and a separate virtual bracket body retrieved from a library of virtual bracket bodies. The virtual brackets can be represented as a file containing digital shape data and exported to a rapid prototype fabrication device for fabrication of the bracket with wax or other materials and the wax prototype can be used for casting with a suitable alloy. Other manufacturing methods including milling and laser sintering can be considered.

Title: Method and apparatus for rapidly generating tools for manufacturing composite parts
Applicant(s): Boeing Co. (USA)+(The Boeing Company)
Publication date: 22 December 2010
Patent number: GB 2471166 (A)
A method and apparatus for manufacturing comprises forming a shell having a support structure located in a cavity which is filled with a curable filler material to form a tool. The shell and the support structure may be formed using an additive manufacturing system (such as fused deposition modelling, selective laser sintering and stereolithography) from a design of a tool. Preferably the tool is used to lay up and cure a number of composite materials to form a part for an aircraft. The filler may be an epoxy, a thermally conducting epoxy, a polymer or a cement and the shell and support structure may be formed from a plastic, a metal, a thermal plastic, acrylonitrile butadiene styrene, or a polycarbonate. A data processing system may be used to create a design of the tool from an original part in which the design is scaled to take into account changes in dimensions of the shell caused by curing.
Title: Customized implants for bone replacement
Applicant(s): Arkema, Inc. (USA); Defelice Scott F (USA); Decarmine Anthony (USA)+
Publication date: 18 February 2010
Patent number: WO 2010019463 (A1)
The present invention relates to customized implants for bone replacement that are prepared from poly(ether ketone ketone) or PEKK, and to a computer-based imaging and rapid prototyping (RP)-based manufacturing method for the design and manufacture of these customized implants. The PEKK customized implants made using rapid prototyping demonstrate biomechanical properties similar (if not identical) to that of natural bone even when prepared without the use of processing aids such as carbon black and aluminum powder.
Title: Three-dimensional circuit manufacturing process and composite components of laser plastic material and manufacturing method
Applicant(s): Hunan Meina Technology Co., Ltd +(Hunan Meina Technology Co., Ltd)
Publication date: 13 October 2010
Patent number: CN 101859613 (A)
The invention relates to a three-dimensional circuit manufacturing process, matched composite components of a laser plastic material, and a manufacturing method, in particular to a packaged technology which utilizes laser scanning to selectively deposit an accurate and tight conductive circuit and directly welds electronic components on a plastic surface. The method comprises the following steps:
Synthesizing the laser plastic material containing an organic metal compound.
Carrying out injection molding on the laser plastic material to obtain plastic pieces.
Selectively scanning the plastic pieces by laser to form a pattern reducing metal particles.
Carrying out rapid ultrasonic electroless plating to thicken the metal layer on the pattern and form a continuous conductive pattern.
Carrying out plasma chemical polishing (optional).
The invention also fuses a laser layering sintering (SLS) rapid forming technology, provides process and equipment innovation, and becomes a environmental-friendly and flexible intelligent manufacturing core technology for a new generation of electronic, electrical and electromechanical integrated products; and the invention can be applied to electronic industries, aerospace, transportation, industrial control and other fields.
Title: Virtual prototyping and testing for medical device development
Applicant(s): Boston Scient Scimed, Inc. (USA)+(Boston Scientific Scimed, Inc.)
Publication date: 3 February 2011
Patent number: US 2011029297 (A1)
A system and method of developing better-designed medical devices, particularly cardiovascular stents and endovascular grafts. The system comprises a geometry generator, a mesh generator, a stress/strain/deformation analyzer, and a visualization tool. In one embodiment, the geometry generator receives three-dimensional volumetric data of an anatomical feature and generates a geometric model. The mesh generator then receives such geometric model of an anatomical feature or an in vitro model and a geometric model of a candidate medical device. In another embodiment, the mesh generator only receives a geometric model of the candidate medical device. Using the geometric model(s) received, the mesh generator creates or generates a mesh or a finite element model. The stress/strain/deformation analyzer then receives the mesh, and the material models and loads of that mesh. Using analysis, preferably non-linear analysis, the stress/strain/deformation analyzer determines the predicted stresses, strains, and deformations on the candidate medical device. Such stresses, strains, and deformations may optionally be simulated visually using a visualization tool.
