Thanks, Alessandro, this is very interesting. Polymers should actually be relatively easy to produce on the surface of Mars using hydrogen from Mars surface water as well as carbon dioxide from the atmosphere. I'll try to follow up on this during our next telecon.<br>

The attached paper reports soil composition for some samples of martian regolith. RepRap seems to work with polycaprolactone (polymeric chains of methylene, CH2). Hope it is useful to foster further discussion.<br><br>Regards,<br>

<div>Hi all,</div>
<div> </div>
<div>Found an interesting article about an open source project with the goal of building a self-replicating 3D-printer:</div>

<div>This would be of particular interest if one could use Martian regolith for printing. Does anyone know about the adhesive properties of Martian regolith?</div>
<div> </div>
<div>Cheers,</div>
