3D-Printed Villa

Recommended Posts

There is a video in the article (see link below). I have not got my mind around all this newfangled 3-D "printing" malarkey. 3-D printed cars, guns, Villa's - what next?

How does 3-D printing work? Has anybody here tried it?

Shanghai company unveils 3D-printed villa WinSun Decoration Design Engineering prints the future of home construction with a 3D-printed villa

china-winsun-3d-printed-villa-six-floor-

It looks like an average home, but look a little closer and you'll see the multiple layers which created this 3D-printed villa.

In Suzhou, eastern China, WinSun Decoration Design Engineering is showing off its latest feat of innovative construction.

Last April, the Shanghai-based company made a name for itself by proving they were able to build 10 homes in less than 24 hours.

This record-speed was achieved using a giant 3D printing machine, measuring 105ft long (32 metres) and 21ft tall (6.5 metres).

Now, Winsun is holding a 3D printing construction global conference, demonstrating the unique possibilities the technology creates for the construction industry. Future applications the company envisages include printed bridges, tall buildings built onsite and maybe one day, fully 3D printed villages.

Giant 3d printers are using cement and construction waste to build homes already in China, you can build 10 houses in 1 day....

How 3D Printing Will Revolutionize Our World

Once they get cheap enough, i guess every home will have one

but, in China, in spite of hundreds of thousands of empty homes, you still need mortgage, and a job, to get one.

Quite simple really, you take a 3D model of what you want to build and based on the type of material and equipment you are using you set the parameters of a layering program that creates printable layers of whatever material you have at the appropriate speed and thickness. The home machines are generally printing ABS plastic or PLA - a starch derived plastic. People have printed clay and fired it, pritned recycled / pelleted white goods plastic for furtniture scale prints, similar to the printed car in terms of features / texture. You can print reaction chanbers for specialist chemistry - the chemicals react and flow to next chamber in whatever complexity you want - quite unique app that one, Syntetic metals can be printed (plastics with a large metal content, or you can bake hard ceramic or even just use the print method to create a mould for metal pour - can even do that with standard PLA. There's also growing numbers of flexible / rubberised materials which will print with the same extrusion head- or mount two and you can have a hard and a flexible component to the print - think making joints / medical devices.Larger scale you get into rapid setting concrete (contour forming) or a forming material that allows you to set concrete within the printed structure. In terms of product maturity really jsut scratching the surface of what can be done.

"Meet Easton LaChappelle, the teenager who built a prosthetic arm from scratch because he met a little girl using a limb that cost $80,000. That struck him as far too much.
So Easton taught himself robotics and combined open source designs with 3D printing to create a completely functional prosthetic arm for less than $400. Even as Easton refines his designs, he continues to post his designs online for anyone to refine, repurpose, and use."

That explains it. 'Printing' is a funny term to use though. Thanks all.

Very similar electronics / mechanics in many ways, an inkjet pritner just missing the z-axis as only printing on one layer. FDM is one of the technical names for it - Fused Deposition Modelling.

Ah, I just thought of something, they can't print gold!

In your faces housebugs. Hoorah for the goldbugs!

I have used 3D printers at work.

I first came across one in 2012, I was working on a vehicular project in charge of the driver controls (panels, switches etc). The CAD files were used to print off solid models to fit into the physical mock up.

Back then it took 24 hours to print off one item.

They work by layering a "substrate" material bit by bit (literally).

The substrate can be any thing. In my case it was a plastic substance heated to liquid...but the OP obviously quotes a concrete type material.

Metal and glass are also used now.

Even discarded plastic can be used.

This will change manufacturing and bring the manufacture of artifacts into the home via file sharing.

It will do to manufacturing what Napster, iTunes etc did to the recording industry and what desktop publishing did to the print industries...change them forever.

Check out reprap.

The documentary called Will Work For Free features this technology 41.45 in. This is well worth a watch.

IMPO this will arrive in our homes as quick as normal printing did.

It will reduce the need for unskilled labour...which in a deflation is adding fuel to the flames.

3D printing, nano technology, AI, super conductors, fusion power etc...the world is changing!

I'm trying to remember the title of a SF novel I read back in the early 80s, probably written quite a few years earlier. The premise was a machine had been invented that could copy anything - money, food, even people. Nothing had value anymore as anything could be copied instantly at will - except land. Those who could take and hold land had everything.

Wish I'd been awake then. :(

What if I make one 3D printer replicate itself, and then the two 3D printers print themselves, so it becomes four, and then keep doing that. Then I'd have 1,000,000 3D printers in no time. Then I could make the 1,000,000 3D printers produce one big super 3D printer, then I could get it to make another Earth, and I live on that by myself, with my army of 3D printers!

Also antiques can't be 3D printed, unless they are coupled with a time machine.

True, you might be able to copy a Mona Lisa, but it won't be the original - so hold onto your old junk! It will be money (also).

Although it would be exactly the same?

Ah! But it wasn't painted by the artist in some dank cellar, with blood and sweat etc... The "good will" or the "story" associated is the value. In Star Trek, Picard values history and artifacts from ancient history, in fact he would spend more time digging in the ground if he could. Also artifacts would not be in the 3D printer open source code.

Put 'Army' and '3-D Printers' together and you get ....

US Army to use 3D printing for food, bombs, everything
3D printing will be used to optimise US army operations, from weaponry to medicine and even food, according to a special issue of Army Technology.

Though only a small fraction of the US military’s exorbitant budget is allocated to research and development, the department promises grow on-site technology capabilities whilst also cutting costs. How? 3D Printing.

The Army’s partnerships with private enterprise, as well asfederally funded tech initiatives, have put the organisation at the cutting edge of digital manufacturing.

Dale Ormond, Director of Research and Development, said: “Imagine the possibilities of three-dimensional printed textiles, metals, integrated electronics, biogenetic materials and even food. Army researchers are exploring the frontiers of an exciting technology.”

I think I will put up a list of 3D printing stocks in this post. Maybe they can print their share holders some money:

DDD 3D Systems Corporation - in the above links video, that can print food. McDonalds will never be the same again, if it buys into the tech.
XONE ExOne Co
VJET Voxeljet AG
MTLS Materialise
They are all in a bear market right now.
