CNC Furniture has been for a few years already but hasn't really taken off. I believe this is because designers haven't spend enough time designing with that technology in mind. Most of the CNC furniture I found online have the typical joinery exposed or have a rigid feel. I played around with the ShopBot Buddy (worktable 4' x 2') and made this chair.

CNC Routers have become affordable in the last couple of years and there are quite a lot of DIY CNC Routers out there. If you have a TechShop close by you can probably make it over there.

Design Concept: One of my favorite chair designs is Eames LCW molded plywood lounge chair. It's a design classic and the fine detailed surfacing work is incredible as well as comfortable. It has been a source of inspiration for quite a lot of my furniture and in this case while using a completely different technology I was able to resemble his masterpiece.

Step 1: Materials

Materials:

  • ¾ inch pre-finished maple plywood (2 sheets 4'x2')
  • Shopbot
  • ¼ inch End Mill
  • Table Router with round bit (optional)
  • Wood Clamps
  • Wood Glue

IMPORTANT: measure the thickness of your plywood! I purchased the 3/4 plywood in 0.75” thick (19.05 mm) but as you can see from the photo, it was 18.65 mm thick. This is really important to take note because the design has locking parts/pockets and we need to accommodate for a thinner/thicker material.

<p>Beautiful chair! Can you please send the file to anthonypaino11@gmail.com ?? THANK YOU</p>
<p>Hello! do you recive the plans? i am needing too</p>

A great Design. Looks so beautiful and is practical also. Comfortable to sit and looks stunning. Very done creator.
<p>I'm studying Industrial Design, and I made this for a class, first with paper battery, then with MDF :)</p>
<p>Muy bueno! Felicitaciones!</p>
<p>Great design!</p>
<p>Thanks!</p>
I made it only just a littke different. The seating and back are made off 3 later bent plywood.<br><br>Very Nice design!
<p>Yours looks beautiful! Really nice work. What technique did you use to bend the seat and back?</p>
<p>Congratulations, beautiful work! Please, will you send me the dxf file to ovolpato (at) gmail.com? Thank you.</p>

<p>hi, @alepalan , can you mail me the dxf file info@tinok.com.ar ?..im excited to make this chair thanks!</p>
<p>hi, @alepalan , can you mail me the dxf file tocarlosmbernal@outlook.com ?..im excited to make this chair , thank in advance my friend</p>
<p>@alepalan , can you mail me the dxf file to Sam.rock.dedhia@gmail.com im excited to make this chair on my cnc router..and use it for my garden</p>
<p>We just started making this in FabLab Odemis in Izmir, Turkey. I've been obsessing over these chairs since forever, so THANK YOU SO MUCH!</p>
<p>You're welcome! Really glad you're making the chairs, please Add Images! I'd love to see them!</p>
<p>How can I get the cnc file?</p>
<p>Excellent design, thanks!</p>
<p>Great Work!! Really nice to see these made! Did you make them at Techshop? I see the logo in the back!</p>
I sure did! I was able to fit all four of these guys on the ShopBot Alpha. In case anyone is thinking of doing the same, add tabs if you're doing a whole sheet. I had some near disasters before doing that...
<p>Nice! The tabs thing is actually true. I think it is better but a little more work afterwards.</p>
<p>Awesome Instructable! Chair came out looking great, even better its super comfortable.</p>
<p>Great work!</p>
<p>Thanks for sending the photo! The chair looks awesome!! Great job!</p>
<p>In the beginning of your instructable you said </p><p>&quot;<strong>IMPORTANT: measure the thickness of your plywood! I</strong> purchased the 3/4 plywood in 0.75&rdquo; thick (19.05 mm) but as you can see from the photo, it was 18.65 mm thick. This is really important to take note because the design has locking parts/pockets and we need to accommodate for a thinner/thicker material.&quot;</p><p>How do you accommodate for different thicknesses? I can not find where you covered this besides the beginning. </p>
<p>I accomodate it manually since I designed the chair. I don't know how to increase it if it is a thicker/thinner material.</p>
<p>Darn because the test piece I cut out looks like this: </p>
<p>I don't know how are you making your toolpaths but my guess is that you are making the pockets wrong. </p>
<p>Hello, I wonder what the distance you have to put the perfect fit in the pieces that are fitted together?</p><p>If the plate has 18mm wood as should be the measure of the fit of the parts? 18.3mm? </p><p>Thank you!</p>
<p>I don't know if I understand the question but let me try and answer. The perfect fit should be 0.1 mm between the 2 parts. It's wood so you can always make it pressure fit.</p>
<p>My pass depth was 0.26&quot;.</p>
<p>Awesome! One last question before I make it, what speed (ipm) did you run the cnc at for the cuts? </p><p>Thanks for this awesome chair design! </p>
<p>Thanks again! I don't remember...Someone had used the 1/4 inch End Mill and set up the speed and feed rate. Do you have the shopbot starter kit bits loaded? I remember there was a 1/4 inch end mill that you can try and use.</p>
<p>Darn... I only ask because I haven't cut much wood and the wood I have cut always ends up burning because I can't get the feed speed (or spindle speed) right. I don't have a shotbot, its my personal CNC that I'm still fairly inexperienced with. </p>
<p>What pass depth did you use for both the profile and pocket cuts? </p>
<p>brillant !!!</p>
<p>Thanks!</p>
<p>Actually I guess the same could be made using a hand operated router with plywood templates.</p><p>Then again, this would be for luddites such as me as a CNC router would make the cut a 100% fool proof.</p><p>Its brilliant anyway.</p>
<p>Yep, it can be done with a manual router, although I think it will be quite a lot of work...</p>
<p>It sure would be a revival of old hands techniques !!!</p><p>Then again, that's how modern furniture from the 1920's to the 80's was built !</p>
<p>I'm loving this chair! Really want to make one for my halls and one of the other chairs. I like it as a budget DIY lounge chair wood.</p>
<p>Awesome, please make them and post pictures here!</p>
<p>Very nice!</p>
<p>Thank you!</p>
<p>Really really nice!</p><p>Now I have something else to build :D</p>
<p>Thanks! :)</p>
