This project explores the possibilities presented by 3d printing to advance traditional joinery techniques beyond what is possible to do in wood alone.

Step 1: Design

Like other 3d-printed/mixed media projects I've done before, the design builds all the complexity into the 3d-printed pieces and lets the wood be as simple as possible. The challenge for this project was to get a tight fit at the joint while using only wood and the 3d-printed connector - no glues or fasteners of any kind. Consequently, the system had to be able to accommodate variations in the wood while also maintaining the predetermined geometry of the 3d print. Ultimately, I landed on the cross tenon shape as an evolution of the traditional wedged tenon joint. The cross tenon joint allowed for a customizable fit for each joint that turned out to be very sturdy, as it can expand in four directions rather than just two.

<p>Awesome Project! You are a great designer! </p><p>I would like to print it. </p><div><p>I need to know which unit of measurement you used in the.stl file. Inches or centimeters? </p></div>
<p>or other unit of length?</p>
<p>Nice. Its simple and efficient. Nothing more to ask.</p>
is it possible that you upload the file for the Joints! thanks
<p>Done! </p>
<p>waow its amazing</p>
<p>Cool........like it.</p>
Nice idea, have you thought about cnc'ing the braces out of wood, or maybe aluminum?
<p>Hmm..It might be a really tricky part to CNC. But I have considered casting it...</p>
<p>Cool Design. Great project.</p><p>But what kinda 3D printer did you use? Looks like SLA on the first glance.</p>
<p>Thanks! I used an Objet FDM printer for this project.</p>
