Appeal 2007-2909
Application 10/622,063
1 11. A robotic pen comprising:
2 a computer numerically controlled machine including a stage
3 for mounting a workpiece for rotation and orthogonal translation, the
4 said stage permitting translation generally in a plane and rotation
5 about an axis generally parallel to said plane, and an elevator for
6 translation from said stage;
7 a pen tip rotatably mounted to said elevator;
8 a dispenser joined in flow communication with said pen tip for
9 ejecting a stream of material atop said workpiece.
10 24. A robotic pen comprising:
11 a machine including a stage for mounting a workpiece for
12 rotation and orthogonal translation, the said stage permitting
13 translation generally in a plane and rotation about an axis generally
14 parallel to said plane, and an elevator for translation from said stage;
15 a pen tip rotatably mounted to said elevator for rotation about
16 an axis generally parallel to said plane;
17 a dispenser joined in flow communication with said pen tip for
18 ejecting a stream of material atop said workpiece; and
19 a digital controller configured for coordinating relative
20 movement of said pen tip and said stage, and dispensing of said
21 stream from said pen tip.
