20130073068 | SOLID FREEFORM FABRICATION USING A PLURALITY OF MODELING MATERIALS - A system and methods for solid freeform fabrication of an object is disclosed. The system comprises a solid freeform fabrication apparatus having a plurality of dispensing heads, a building material supply apparatus configured to supply a plurality of building materials to the fabrication apparatus, and a control unit configured for controlling the fabrication apparatus and the supply apparatus based on an operation mode selected from a plurality of predetermined operation modes. | 03-21-2013 |
20130040091 | SOLID FREEFORM FABRICATION OF SHELLED OBJECTS - A method of layerwise solid freeform fabrication is disclosed. The method comprises, for each of at least a few of the layers, dispensing and hardening at least a first modeling material and a second modeling material to form a core region and one or more envelope regions at least partially surrounding the core region. In some embodiments, the ratio between the elastic moduli of adjacent regions, when hardened, is from about 1 to about 20. | 02-14-2013 |
20120316669 | RAPID PROTOTYPING APPARATUS - 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. | 12-13-2012 |
20120276233 | PREPARATION OF BUILDING MATERIAL FOR SOLID FREEFORM FABRICATION - A method suitable for solid freeform fabrication is disclosed. The method comprises mixing respective amounts of a plurality of materials such as to provide a building material characterized by at least one attribute, and using the building material for fabricating a three-dimensional object. | 11-01-2012 |
20120267827 | RAPID PRODUCTION APPARATUS WITH PRODUCTION ORIENTATION DETERMINATION - A method of producing an object by sequentially printing layers of construction material one on top of the other, the method comprising: providing the construction material at a first lower temperature; flowing the construction material through a heated flow path in a flow structure to heat the construction material and delivering the heated construction material to a heated reservoir in a printing head; and dispensing the heated construction material from the reservoir to build the object layer by layer. | 10-25-2012 |
20120224734 | HEARING AID AND METHOD OF FABRICATING THE SAME - A casing device for a hearing aid is disclosed. The casing device comprises an elongated extension fabricated by solid freeform fabrication and being adapted to fit within the auditory canal of a wearer. The casing device has at least two regions each being characterized by a different hardness. The casing device is configured to receive and encapsulate an electroacoustic device. | 09-06-2012 |
