XY Flexure Translation Stage

prusaprinters

<p>This is an XY Translation stage that uses mutually compensating flexures to create "perfect" planar translational movement. In a perfect world, no rotation or Z-Movement would sneak in (but a little does). These stages have a +- 14mm movement range.</p> <p>Because it's all one piece, there's no backlash or friction (from parts rubbing against each other), so this mechanism can be used to build micrometer repeatable motion stages.</p> <p>There's a "Stiff-X-Axis" version of the STL that has much better rotational stiffness (but also more translation stiffness). The "Normal" version of the STL cuts out most of the X-Axis flexures in an attempt to match their stiffness to the Y-Axis, and it has a locator for the lid.</p> <p>This design was inspired by: <a href="https://www.thingiverse.com/thing:2574629">https://www.thingiverse.com/thing:2574629</a></p> <p>Here's a video of the design process:<br/> <a href="https://imgur.com/a/YH4HQpo">https://imgur.com/a/YH4HQpo</a></p> <p>The Fusion 360 designs are here; it's mostly constrained so you can adjust the base sketch to your liking:<br/> <a href="https://a360.co/2zL3d2o">https://a360.co/2zL3d2o</a></p> <h3> Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Prusa</p> <p><p class="detail-setting printer"><strong>Printer: </strong> <div><p>I3 MK3S</p></div><strong>Rafts:</strong></p> <p>No</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div><strong>Resolution:</strong></p> <p>0.3mm DRAFT</p> <p><p class="detail-setting infill"><strong>Infill: </strong> <div><p>5%</p></div><br/> <strong>Filament:</strong><br/> Generic PLA Black <br/> <p class="detail-setting notes"><strong>Notes: </strong> </p><div><p>Print Settings -&gt; Layers and Infills -&gt; Detect Bridging Perimeters = TRUE</p> Print Settings -&gt; Layers and Infills -&gt; Detect Thin Walls = FALSE</div></p> <p>Print Settings -&gt; Advanced -&gt; External Perimeters = 0.4mm</p> <p>If the flexures have two lines running along them, then this was done properly.</p> </p></p></p> Category: Engineering
