Paper, corrugated, or chipboard substitutes for more durable materials will save you time and resources.&nbsp;Print out profiles on a printer and cut them out with a knife to test assembly. Makers who prototype having fully resolved design solutions when they go to the final material.<\/p>\n\n\n\n<p>The transition from digital drawing to physical object can be harder to imagine than one realizes. Often unexpected qualities\u2014both positive and negative\u2014are uncovered in a physical object. A good prototype is the best, and perhaps only, way to test joints, shapes and details.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Kerf\"><\/span>Kerf<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Kerf refers to the amount of material lost to machining. For a laser, it&#8217;s quite small, but it is enough to throw off a snug slot fit or ruin an inlay or jewelry design.<\/p>\n\n\n\n<p>You can find the kerf values for various materials through test-cutting. For super-precise inlay work, you can add or subtract the kerf value from the intended size of your material and this will compensate for the lost material. It&#8217;s a bit like cutting on one side of the line with a saw blade in order to maintain a precise measure, except the values are much smaller than the 0.125&#8243; or so of an average saw blade.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Slot_nodes\"><\/span>Slot nodes<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Even if you account for laser kerf, the tolerance of your material may throw off precision, especially when making a slot or slot-and-tab joint system. Materials can vary in thickness up to 10% of the advertised value.&nbsp;By creating nodes in your slots, you can mitigate this.<\/p>\n\n\n\n<p>Nodes are little bumps located in the slots or on the tabs in your project that are sized to compensate for tolerance and kerf. Nodes compress as a product goes together, providing friction at specific points rather than along the entire slot length. This allows a slot to be designed a small fraction wider at the opening, which permits parts to be easily slid together, yet still provide a tight friction joint.<\/p>\n\n\n\n<p>There are several keys to a successful node design:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Design with paired symmetry<\/strong>&nbsp; |&nbsp; It\u2019s better to have nodes on both sides of a slot precisely mirroring each other. Asymmetrically offset nodes can introduce twisting and buckling.<\/li>\n\n\n\n<li><strong>Smooth curve shape<\/strong>&nbsp; |&nbsp; This allows strong friction without introducing resistance to assembly.<\/li>\n\n\n\n<li><strong>The more the merrier<\/strong>&nbsp; |&nbsp; If the size of the slot allows, create multiple sets of nodes. Create one pair near the slot opening, one at the midpoint, and one near the terminus.<\/li>\n\n\n\n<li><strong>Longer is gentler<\/strong>&nbsp; |&nbsp; The smooth curve shape works better with a longer node, if the slot size allows. Make nodes 0.25&#8243;\/6mm or longer.<\/li>\n\n\n\n<li><strong>Depth depends on density<\/strong>&nbsp; |&nbsp; If using a dense material (HDF, acrylic), the nodes should be shallow, since the material will exhibit little compression\u2014a node perhaps as shallow as 0.005&#8243; to 0.010&#8243; may suffice. Less dense materials (basswood, museum mounting board) will compress more, and a node of 0.020&#8243; will be possible. Prototyping with a simple slot-and-tab model will help you apply the right depth of node to your material.<\/li>\n<\/ul>\n\n\n\n<p>Brittle materials like acrylic may not like a deep node at all, although there are ways to keep corners from cracking&#8230;&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Corner_radii_in_acrylic_slots\"><\/span>Corner radii in acrylic slots<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<p>A sharp corner in brittle materials like acrylic will fracture when compressive forces are applied. There is a remedy, however. A sharp corner effectively generates an inherently weak point in acrylic. A small radii at the corner will transfer compressive forces from one face of the hole or slot to the other and reduces the risk of the material splitting at the corner.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" data-attachment-id=\"1601\" data-permalink=\"https:\/\/williamcromar.com\/newmediawiki\/laser-fabrication\/slots\/\" data-orig-file=\"https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/slots.jpg\" data-orig-size=\"1956,1956\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"slots\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/slots-1024x1024.jpg\" src=\"https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/slots-1024x1024.jpg\" alt=\"\" class=\"wp-image-1601\" style=\"width:300px\" width=\"300\" srcset=\"https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/slots-1024x1024.jpg 1024w, https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/slots-300x300.jpg 300w, https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/slots-150x150.jpg 150w, https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/slots-768x768.jpg 768w, https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/slots-1536x1536.jpg 1536w, https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/slots-100x100.jpg 100w, https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/slots.jpg 1956w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div><\/div>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Joints_with_fasteners\"><\/span>Joints with fasteners<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>An alternative to friction joints or glue is the T-slot joint.

Using corner radii on the cutouts reduces the risk of cracking if the bolt is overtightened.&nbsp;Combine a rubber washer with the captive nut and bolt, and this further reduces the chance of damage.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"300\" data-attachment-id=\"1602\" data-permalink=\"https:\/\/williamcromar.com\/newmediawiki\/laser-fabrication\/t-slot\/\" data-orig-file=\"https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/t-slot.png\" data-orig-size=\"300,300\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"t-slot\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/t-slot.png\" src=\"https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/t-slot.png\" alt=\"\" class=\"wp-image-1602\" srcset=\"https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/t-slot.png 300w, https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/t-slot-150x150.png 150w, https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/t-slot-100x100.png 100w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/figure>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" data-attachment-id=\"1603\" data-permalink=\"https:\/\/williamcromar.com\/newmediawiki\/laser-fabrication\/slots2\/\" data-orig-file=\"https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/slots2.jpg\" data-orig-size=\"1806,1806\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"slots2\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/slots2-1024x1024.jpg\" src=\"https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/slots2.jpg\" alt=\"\" class=\"wp-image-1603\" style=\"width:300px\" width=\"300\" srcset=\"https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/slots2.jpg 1806w, https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/slots2-300x300.jpg 300w, https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/slots2-1024x1024.jpg 1024w, https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/slots2-150x150.jpg 150w, https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/slots2-768x768.jpg 768w, https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/slots2-1536x1536.jpg 1536w, https:\/\/williamcromar.com\/newmediawiki\/wp-content\/uploads\/2023\/08\/slots2-100x100.jpg 100w\" sizes=\"(max-width: 1806px) 100vw, 1806px\" \/><\/figure>\n<\/div><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Fabbing 2D-3D | line &gt; plane laser fabrication Laser cutter and engraver safety training MakerSpace Visit the MakerSpace website here.
