Do you have a NURBS object you wish to 3D print? Select the model and go to <strong>Modify&gt;Convert&gt;NURBS to Polygons<\/strong> in any menu set. Often the converted object needs the normal angle reset (see explainer below). It may also want more geometry, created via Smooth Mesh Preview conversion.<\/p>\n\n\n\n<p>If this or any other model situation depends on Smooth Mesh Preview (3 on the keyboard), be aware that what you see in the Maya viewport <em>is not what will be printed<\/em>. The 3D driver does not recognize the Smooth Mesh. While you are still in Maya you can go to <strong>Modify&gt;Convert&gt;Smooth Mesh Preview to Polygons<\/strong> and get a high-resolution mesh.

Clean with isopropyl alcohol or Windex if needed.<\/li>\n\n\n\n<li>Run the job. Watch the first layer print completely. Print adhesion of the first layer is where 95% of all print fails happen.<\/li>\n\n\n\n<li>Once the print is well-established, you may leave and pick up your print when ready.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Post-production\"><\/span>Post-production<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The machine is very slow, but post-production can also be time consuming! Training for post-production work has already been covered by the live demo and the safety training video mentioned above. Typically, you are removing a brim and support material from the model, with some sanding or smoothing from time to time.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Reserve_a_time\"><\/span>Reserve a time<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Most people find it more convenient to use our tools to do these steps. Reserve an <strong>Open Workspace<\/strong>  (just one of the empty tables) at the MakerSpace. Reserving not only guarantees that you have a space to work, but it gives us data to prove the MakerSpace is wanted and needed by our community \u2014&nbsp;meaning we are rewarded with more resources to serve <strong>you<\/strong>!<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Document_the_results\"><\/span>Document the results<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Show off your finished print on your process journal or blog by taking simple but careful photographs. <\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Clean the lens!&nbsp;<\/strong>| When you pull your phone out of your linty pocket with your smudgy fingers, the lens gets dirty. Lens cloth and cleaner are best, and MakerSpace has some. But even wiping with your T-shirt is OK!<\/li>\n\n\n\n<li><strong>Framing<\/strong>\u00a0| Use the Grid to help compose your image. (In iOS: Settings > Camera > Grid. In Android: Settings > Apps > Camera > Grid Lines). Choose a frame proportion (like Photo or Square in iOS) and orientation.<\/li>\n\n\n\n<li><strong>Composition<\/strong>&nbsp;| Your work is the focal point. Provide only enough background for us to understand this is an image of your fabrication in real space, and make sure everything the field of view is there because you&nbsp;<strong>want<\/strong>&nbsp;it there.<\/li>\n\n\n\n<li><strong>Avoid digital zoom<\/strong>&nbsp;| Instead, move closer to your subject.<\/li>\n\n\n\n<li><strong>NO flash<\/strong>&nbsp;| Always a terrible outcome! Use natural light or position indoor lights deliberately. MakerSpace has a&nbsp;<strong>light-box<\/strong>&nbsp;and&nbsp;<strong>phone tripod<\/strong>. Just sign up for an&nbsp;<strong><strong>Open Workspace<\/strong><\/strong>, and use these tools for easy, simple, professional results!<\/li>\n\n\n\n<li><strong>Steady yourself or use a pocket tripod<\/strong>&nbsp;| Lean against a wall or furniture to help steady your hand. Otherwise, a small tripod is a good choice. MakerSpace has a phone tripod you may use.<\/li>\n\n\n\n<li><strong>Play with editing and exposure<\/strong>&nbsp;| You can make color more saturated, crop an image, brighten a dark image or vice versa.
