In the following steps - I'll quickly explain the process that I used to prototype an organic chair that I modelled in 3D software.

I developed the prototype in the FabLab Lisboa: http://fablablisboa.pt

Step 1: Creating the 3D Model of the Marsupial Chair

I modelled a chair in 3D and I decided to develop the prototype in a CNC milling machine, to study the egonomy of the model. To develop the prototype I contact the FabLab Lisboa that has a CNC milling machine.

Step 2: Preparing the 3D Model for CNC Milling

I sliced the 3D model in slices of 5 cm's - the same thickness of the Styrofoam Boards.

Step 3: CNC Milling the Slices

After slicing the 3D model - I attached the slices in different groups in order to organize the CNC milling process and monetize the styrofoam boards.

Step 4: Gluing the Styrofoam

After finishing the CNC milling process, I glued all the slices and I presented the prototype in FabLab events, in Lisbon - in which the prototype is making success.

<p>Best chair i have ever seen!!! Bravo!!!</p>
Hi. Thank you for your Feedback!
<p>Nice What cad program did you use?</p>
<p>nice!</p>
<p>That chair is rad! What material will you use for the finished piece?</p>
<p>Hi. For the final coating: I received an advise to experiment a quick process of coating with &quot;self levelling resins&quot; - it can be applied with a spray painting gun. I also pretend to develop some replicas in fiberglass or in sisal fiber.</p>
<p>I think the word your looking for instead of &quot;pretend&quot; in intend. Pretend is to make believe or daydream. Just trying to help out.</p>
<p>This is awesome! I've always thought that CNC furniture is awesome! </p>
