<p dir="ltr">Exporting the sliced model as OBJ can be useful if you’re familiar with a 3D modeling and rendering program. When you slice a model, you can choose <strong>File - Export - Export toolpath as OBJ</strong>. You can then import that file into a 3D software that you like, such as Blender, and render photorealistic previews or even animations of the print.</p>
<p dir="ltr">The export includes everything you currently see in the Preview. That means, if you use the layer slider to preview a cross-section of the model, the exported file will include only the layers visible in the Preview.</p>
<div class="tip-callout">If you plan to render only the outside of the sliced model, we recommend turning the infill off completely, keeping the layer height above 0,15 mm, and decreasing the number of perimeters to 2 in order to reduce the polygon count. Still, you can expect several million polygons per model.</div>

3Dconnexion devices

<p>By default, PrusaSlicer places the bottom-most point of each object on the build plate.</p>
<p>In the vast majority of cases, this saves the user time and prevents possible failed prints, where the model would be accidentally slightly lifted above the print bed. However, in some cases, you might want to lift an object above the print bed on purpose. For example, you might want to add a logo or text on top of another object.</p>
<p>The way to do it currently is to use a&nbsp;<strong>multi-part object</strong>. Only the bottom-most part of a multi-part object will be placed on the build plate. Other parts can be lifted from the build plate freely.</p>
<h3>Load the "levitating" object as a part</h3>
<ol>
<li><strong>Right-click</strong> an existing object in the 3D View</li>
<li>Select <strong>Add part - Load object..</strong> (or select any of the basic primitives from the list)</li>
<li>Select the <a href="https://help.prusa3d.com/en/article/move-rotate-scale-tools_1914"><strong>Move</strong> <strong>tool</strong></a> from the left menu</li>
<li>Move the part wherever you want it (or use the <a href="http://help.prusa3d.com/article/object-manipulation-panel_1757">Object manipulation panel</a> to enter precise values)</li>
</ol>
<p><video autoplay="autoplay" loop="loop" controls="controls" width="925" height="auto"><source src="https://cdn.help.prusa3d.com/wp-content/uploads/2021/08/lift_object.mp4" type="video/mp4"></video> &nbsp;</p>
<h3>Merge multiple objects</h3>
<p>You can also create a multi-part object by merging multiple objects together</p>
<ol>
<li>Select multiple objects (Use box selection or Ctrl+left mouse button click to add an object to current selection)</li>
<li><strong>Right-click</strong> any of the models</li>
<li>Select&nbsp;<strong>Merge</strong></li>
<li>Select individual part using the Object list</li>
<li>Select the <strong><a href="http://help.prusa3d.com/article/move-rotate-scale-tools_1914">Move tool</a></strong> from the left menu</li>
<li>Move the part wherever you want it (or use the <a href="http://help.prusa3d.com/article/object-manipulation-panel_1757">Object manipulation panel</a> to enter precise values)</li>
</ol>
<h4>Selecting individual parts</h4>
<p>When you click on a multi-part object in the 3D view, all parts will be selected. Use the <a href="http://help.prusa3d.com/article/object-list_1758">Object list</a> in the right panel to select individual parts.</p>
<div class="embed-container" style="position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; max-width: 100%;"><iframe style="position: absolute; top: 0; left: 0; width: 100%; height: 100%;" src="https://www.youtube.com/embed/NAW2JR-D_QU?start=3246" frameborder="0" allowfullscreen="allowfullscreen"></iframe></div>
<h3>Why don't we simply allow lifting objects up?</h3>
<p>Contrary to other slicers, PrusaSlicer slices each object independently and it also builds supports for each object independently. This approach is beneficial in many ways, it allows us to do tricks like variable layer height, support stepping independently per object or reslicing only part of the scene when a parameter changes to save time. On the other hand, it also means that objects, and more importantly, supports from two separate objects can collide. Placing one object on top of another and enabling supports would counterintuitively build supports through the bottom object, which would be difficult to see in the preview and ruin the print. Indeed, intersecting supports for objects placed close together is relatively frequently reported as a bug even now.</p>
<p>In addition, the assumption "objects are not floating" is present in many places of the codebase, and there is no simple way to simply allow lifting objects up without breaking many of the existing features.</p>
<p>To summarize, in order to enable this in the future, we will also have to implement:</p>
<ol>
<li>Collision detection on the plater. We already have the infrastructure in PrusaSlicer for that.</li>
<li>Collision of supports from different objects.</li>
</ol>
<p>With that, the user will get meaningful feedback if the print is not printable (floating in mid-air or having overlapping extrusions) Implementing all of this will be fairly difficult. With some more requested tasks from the community having a higher priority for us, we have no estimated deadline for implementing this.</p>
