Title: System and methods for increasing efficiency in rapid prototyping processesApplicant: Spiridonov Anton; Sambu Shiva P; Borovinskih Artem; Dhagat Maneesh; Ivanov VasiliyPatent number: US2009037011Publication date: 5 February 2009
A system and methods for batch sorting objects and mapping the objects on a tray having a fixed dimension along an x-axis and a fixed dimension along a y-axis. Certain aspects of the present embodiments include: (a) storing the objects in a queue; (b) sorting the objects in the queue according to a dimension of the objects; (c) mapping the objects sequentially into a first column of a plurality of columns on the tray until the first column is filled; (d) mapping the objects into a subsequent column until the subsequent column is filled; (e) repeating step; (d) until only a last column in the plurality of columns remains to be filled, or until no more objects remain in the queue; and (f) mapping the objects into the last column in accordance with a column organization plan. In certain embodiments, at least one of the columns, and not necessarily the last column, includes objects mapped in accordance with a column organization plan.
Title: Process for producing an object having at least two moving partsApplicant: Fraunhofer Ges ForschungPatent number: US2008282527Publication date: 20 November 2008
A process for producing an object having at least two component parts which can move relative to one another is proposed. This involves preparing geometrical data of the entire object for a rapid prototyping process, with a predetermined minimum spacing between the moving parts being taken into consideration. According to the predetermined geometrical data, a first material as support material and a second material as material for the component parts are applied in layers, the support material filling gaps including those constituting the minimum spacing between the respective material for the component parts. Following completion of the layered construction, the support material is removed.
Title: Application search tool for rapid prototyping and development of new applicationsApplicant: Accenture Global Services GmbHPatent number: US2008288965Publication date: 20 November 2008
A code search tool greatly reduces time, cost, and other resource expenditures associated with implementing a new application. The tool is a search, navigation and visualization tool that accepts high-level processing concepts as inputs to identify, rank, and return the code of relevant existing applications. A software developer may use the relevant applications to rapidly build prototypes, identify requirements, and develop new applications. The tool provides an efficient way to improve the reuse of application logic to realize the high-level processing concepts, and more efficiently deliver proof of concept.
Title: Method for producing 3D objects using segmental prototypingApplicant: Korea Inst Science TechnologyPatent number: US2009085257Publication date: 2 April 2009
The method for manufacturing large three-dimensional objects of the present invention comprises the following steps: obtaining a 3D shape data for a 3D target object; converting the 3D shape data into a size needed for manufacturing; transforming the size-converted data into a “shell” data (i.e. data of a hallow target object having a cavity therein); dividing the “shell” data into shell segments of such a size that can be manufactured by a rapid prototyping apparatus; prototyping each of the “shell” segments by a rapid prototyping apparatus to manufacture each of prototyped parts; assembling the prototyped parts to produce a prototype of the target 3D shape object.
Title: Polymer object optical fabrication processApplicant: Poof Technologies LLC; Cregger Robert BrianPatent number: WO2008063433Publication date: 29 May 2008
High-volume mass-production and customization of complex 3D polymer and polymer-derived-ceramic microstructures are manufactured in a single step directly from 3D computer models. A projection based non-degenerate two-photon induced photopolymerization method overcomes the drawbacks of conventional one- and two-photon fabrication methods. The structure includes dual, synchronized, high-peak power, pulsed femtosecond and picosecond lasers combined with spatial light modulation. Applications include high-resolution rapid prototyping and rapid manufacturing with an emphasis on fabrication of various micro-electro-mechanical systems (MEMS) devices, especially in the area of MEMS packaging.
Title: Rapid production apparatusApplicant: Objet Geometries LtdPatent number: DE602004008458Publication date: 21 May 2008
Apparatus for producing an object by sequentially forming thin layers of a construction material one on top of the other responsive to data defining the object, the apparatus comprising: a plurality of printing heads each having a surface formed with a plurality of output orifices and controllable to dispense the construction material through each orifice independently of the other orifices; a shuttle to which the printing heads are mounted; a support surface; and a controller adapted to control the shuttle to move back and forth over the support surface and as the shuttle moves to control the printing heads to dispense the construction material through each of their respective orifices responsive to the data to form a first layer on the support surface and thereafter, sequentially the other layers; wherein each printing head is dismountable from the shuttle and replaceable independently of the other printing heads.
Title: Rapid-prototyping method and radiation-hardenable composition of application theretoApplicant: Univ Wien TechPatent number: AT414602Publication date: 15 December 2008
The invention relates to a method for production of 3D objects, comprising the production of a 3D structure, by sequential selective hardening of layers of a composition which may be hardened by visible and/or ultraviolet light to give a solid polymeric material, whereupon a 3D object is produced using the 3D structure, the 3D structure then being removed out of/from the 3D object, characterized in that the removal of the 3D structure is achieved by chemical cleavage of the polymer material and simultaneous or subsequent dissolution of the materially in a solvent or solvent mixture and/or melting of the material.
