THREE-DIMENSIONAL MODELING SYSTEM AND METHOD

A three-dimensional modeling system for creating an object having a three-dimensional modeling printhead, wherein the printhead is attached to positioning means spatially moving at least one of the printhead and the object being printed relative to one another. The printhead having a tubular feed me...

Zusammenfassung:	A three-dimensional modeling system for creating an object having a three-dimensional modeling printhead, wherein the printhead is attached to positioning means spatially moving at least one of the printhead and the object being printed relative to one another. The printhead having a tubular feed member and a nozzle arranged at one end of the tubular feed member, the nozzle having a nozzle outlet for dispensing modeling material modeling material, and a nozzle tip, for interfacing previously deposited tracks of modeling material on the object to be created. The tubular feed member having a feed channel for feeding the modeling material to the nozzle outlet. The system further having modeling material feeding means arranged at an end of the tubular feed member opposite of the nozzle, wherein the modeling material feeding means are arranged for exerting a pressure on the modeling material within the feed channel towards the nozzle. The system further having a pressure determining means for determining a first parameter indicative for a pressure exerted on the modeling material. The system further having a control system arranged for controlling the modeling material feeding means based on the determined first parameter indicative for a pressure exerted on the modeling material. A method of three-dimensional modeling using the system.
