3D Home printing

This is quite interesting:

[www.contourcrafting.org]

I suggest reading the paper on ceramic analysis. They use an interesting linear ball screw extruder plus they add a gimbaled trowel on the side of the extrude to smooth out the surface...

Somewhere on this forum is a link to a youtube video that shows a machine actually using an XY plotter to lay out cement and build a building that way. Actual production, not simply a hoped for project. Alas, I can't find it

I couldn't find it either...but I have not seen this being used in real home building yet, but maybe it is. the ousing crisis has realy put a damper on investment in such technologies for the time being.

Machines like this have been laying kerbs for decades. They're under human operator control and extruding a single-layer course, but the extrusion mechanics are broadly similar.

Printing a home instead of a curb is probably an order of magnitude harder. Much more to deal with in a home like compressive forces, sharp corners, strength issues, accomodation of mechanical and electrical systems, etc....

Clearly its a problem cause they aren'y printing homes yet. When they do, it should results in a radical lowering of time and costs for new homes.

Hi Guys

Im a masters student at Brunel University, London,and im thinking of studying the reprap, Darwin and Mendel machines.
My report will be focused on the problems anyone in the movement may have faced.

So what problems have you faced????....Feel free to list them, big or small.

The reprap machine at school is having serious malfunctions with the extruder so i know your not alone.

Id appreciate your feedback

Thanks

It is not considered good forum etiquette to post the same message in six different forum topics, plus you should have started a new thread in the appropriate forum.

Hardly a good way to introduce yourself when you want help from the people here!
