Appl. No.:

09/248352

Assignee:

3D Systems, Inc. - Valencia CA

International Classification:

B29C 3508

US Classification:

264401, 4251744, 425375, 700120

Abstract:

A rapid prototyping and manufacturing (e. g. stereolithography) method and apparatus for making three-dimensional objects on a layer by layer basis by selectively exposing layers of material to prescribed stimulation, using a beam having a first smaller diameter and a beam having a second larger diameter, to form laminae of the object. The power of the smaller beam is typically lower than the power of the larger beam. Object formation is controlled by data representing portions of the layers to be exposed with the larger beam (large spot portions) and those portions to be exposed with the smaller beam (small spot portions). In a preferred embodiment, portions exposed with the larger beam are formed first, for a given layer. Portions are exposed with the small beam next. Thereafter the entire perimeter of the laminae is traced using the small beam.

International Classification:

B29C 3508
B29C 4108

US Classification:

4251744

Abstract:

A rapid prototyping and manufacturing (e. g. stereolithography) apparatus includes a secondary frame located within a primary frame of the system. The secondary frame defines an enclosure for housing a number of peripheral heat-producing components and peripheral vibration-producing components. The heat generated by these peripheral heat-producing components is substantially isolated in the enclosure and is removed from the primary frame so as not to cause an undesired impact on other components within the main frame. The secondary frame preferably sits directly on the floor or other surface without touching the primary frame, thus substantially avoiding transmittance of vibration from components in the enclosure to the primary frame of the system.

International Classification:

US Classification:

264401

Abstract:

A rapid prototyping and manufacturing (e. g. stereolithography) method and apparatus for producing three-dimensional objects by selectively subjecting a liquid or other fluid-like material to a beam of prescribed stimulation. In a preferred embodiment a source of prescribed stimulation is controlled to reduce or inhibit the production of the prescribed stimulation during at least some periods when the prescribed stimulation is not needed to expose the material. In another preferred embodiment, the source of stimulation is controlled to vary the quantity of prescribed stimulation that is produced and allowed to reach the material. In an additional preferred embodiment control of laser output occurs based on a combination of supplying a regulated amount of voltage to an AOM in conjunction with temporary sensing of laser power and a known desired power to attain. In a further preferred embodiment, a quantity of prescribed stimulation may be set by consideration of desired solidification depths to be used, beam profile characteristics, material properties, and scanning speed limitations for different data types. In a still further preferred embodiment, a transition between selected consecutive exposure vectors is performed by scanning one or more interposed non-exposure vectors with the beam inhibited from reaching the building material.
