Deposition tool with interchangeable material bay
First Claim
1. A drive assembly for use in a solid freeform fabrication system, comprising:
- a drive module comprising a drive mechanism having a first spur shaped drive gear; and
a detachable material bay assembly detachable from the drive module, the material bay assembly comprising a material bay holder, a material deposition tool, and a corresponding material bay actuation mechanism having a second spur shaped drive gear complementary to and configured to engage with the first spur shaped drive gear of the drive module when the material bay assembly is coupled to the drive module such that when the drive mechanism of the drive module is actuated, the second spur shaped drive gear is actuated causing the material deposition tool to deposit material from a material bay inserted in the material bay holder;
wherein the material bay assembly comprises a material bay frame having at least one coupling interface for attachment to the drive module;
further wherein the drive module comprises a drive module frame having at least one attachment interface configured to engage with the at least one coupling interface of the material bay frame to mutually engage the material bay frame and the drive module frame and to mutually engage the first and second spur shaped drive gears;
still further wherein the at least one coupling interface includes a first notch and a first aperture and the at least one attachment interface includes a second notch adapted for engaging the first aperture, and a second aperture adapted for engaging the first notch.

Abstract
Technologies are provided herein for a modular deposition tool design that allows for both, the fast interchanging of materials and for easy cleaning of all wetted surfaces. A drive assembly for use in a solid freeform fabrication system, includes a drive module having a drive mechanism and a detachable material bay assembly that is detachable from the drive module. The material bay assembly includes a material bay holder, a material deposition tool, and a corresponding material bay actuation mechanism that can engage with the drive mechanism of the drive module when the material bay assembly is coupled to the drive module such that when the drive mechanism of the drive module is actuated, the material bay actuation mechanism is actuated, which causes the material deposition tool to deposit material from a material bay inserted in the material bay holder.

6. A material bay assembly, comprising:
-
at least one material bay holder for holding a material bay containing material to be deposited; at least one material deposition tool configured to deposit the material contained in the material bay; a material bay housing comprising a coupling interface configured to engage with an attachment interface of a drive module of a solid freeform fabrication system; and at least one material bay actuation mechanism comprising a first spur shaped drive gear configured to be actuated by a second spur shaped drive gear of the drive module, when the coupling interface of the material bay housing engages an attachment interface of a drive module, for causing the material deposition tool to deposit material from a material bay inserted in the material bay holder when the material bay assembly is coupled to the drive module of a solid freeform fabrication system; wherein the coupling interface includes a first notch and a first aperture adapted for respectively engaging a second aperture and a second notch on the attachment interface of the drive module. - View Dependent Claims (7, 8)
