20130189435, Jul 25, 2013

Filed:

Jan 20, 2012

Appl. No.:

13/355400

Inventors:

Thomas R. Mackie - Verona WI, US
Nathan James Patterson - Fitchburg WI, US
Benjamin L. Cox - Fitchburg WI, US
Nathan D. Schumacher - Madison WI, US
George Wicks Petry - Madison WI, US

International Classification:

B05D 1/26
B05C 11/00

US Classification:

427256, 118696, 118697

Abstract:

A 3-D printer system moves a printed tool over a print surface with a mechanism controlling a rotational angle of an arm holding the print tool and a revolutionary angle of axis of rotation of the printable area to eliminate the disadvantages of conventionally used linear motion mechanisms

Inventors:

- Madison WI, US
Thomas Rockwell Mackie - Verona WI, US
Nathan Donald Schumacher - Madison WI, US

International Classification:

B22F 12/45

B22F 10/28

Abstract:

High-throughput printing, possible with multiple electron beams, is facilitated by a continuous powder bed preparation process operating in parallel to apply and pre-sinter the powder along a continuous helical path. The sintered powder may be self-supporting to allow unconstrained expansion in the radial direction when high energy is used for powder fusion.

International Classification:

B22F 3/105
B32B 38/18

Abstract:

A 3D printer successively fuses sheet material in a stack to form a three-dimensional object. The sheet material may provide a mesh separating islands of material that will be fused to produce the desired three-dimensional object. The mesh provides support for the island material during the fusing process and may be removed afterwards.

Appl. No.:

14/932189

Thomas Mackie - Verona WI, US
Jiju George Johnson - Milwaukee WI, US

International Classification:

G06F 17/50
H04W 4/00

Abstract:

Digitization of a 3-D object is provided by surrounding the object with flowable probes whose positions may be accurately determined. By identifying at least those flowable probes adjacent to the outer surface of the object, a locus of points on the outer surface of the object may be determined from which the object shape may be defined in a model.
