20160185039 | PASSIVE Z-AXIS ALIGNMENT - A three-dimensional printer positions a tool such as an extruder in three-dimensional space using a passive, i.e., non-motorized, z-axis alignment technique that generates z-axis movement based upon motorized movements along another axis.

The passive system may employ a variety of different gearing techniques to convert x-axis or y-axis movements into a z-axis movement under various conditions. For example, the three-dimensional printing tool may move to a predetermined position along a first axis (e.g., an x-axis or y-axis) where a passive gear assembly engages a rack or the like. When in this predetermined position along the first axis, the tool can move along a second axis and create a resulting movement on a third axis (e.g., the z-axis). | 06-30-2016 |
