<p>In the context of a personal project I would like to reproduce the appearance of a commercial product of which I send you a cropped image.</p>

<p>I would also like to point out that I do not have the object in question, but it would seem that it is made from a polymer.  </p>

<p>The product is a case with an embedded electronical card, so heat dissipation is important.</p>

<p>I'm interested by what kind of plastic is really used here. I plan to have the part manufactured by a company, so I think the method used will be SLS</p>

<p>I therefore rely on your expertise in the field of 3D printing to try to identify the material used.</p>

<p>Thanks</p>
