Hello Yves and everyone,

Yes it is moving and it is a very interesting technical subject.
I'm burning to tell you more about the machine built by my young neighbor .... but we are in August and he went on vacation!

Hello Pascal and everyone,

surely interesting this cement 3D printer project ...

quite a technical challenge too !!

Hello Pascal and everyone,

surely interesting this cement 3D printer project ...

quite a technical challenge too !!

"we will be able to make a cement replica - reinforced of course - of each member of our dream TEAM"

At scale 1 ... alluring not? and since the cement proofs are hollow ... we will gladly hide our future inventions there.

:-)

joking aside, the computer / driving part of the engine elements in 3 D is quite difficult to achieve while respecting the specifics of the materials used: the challenge being to obtain tool kinematics not too slow ... but not too fast neither for the cement to be deposited in an optimal manner, by gravity, without having to use pressurization as in traditional injection systems ...

"easy to say less easy to do" .... but now I know that it is possible since I saw it working and I was able to touch it with my hands (dixit St THOMAS).

Hello,

While waiting for Pascal's neighbor 3D printer, here are some services already available:

- rental: interesting option which gives access to technology ... Must see the conditions.

- remote object printing: we send the file to be printed and when returned by mail, we receive the printed object. This option
is very, very interesting and provides access to levels of quality that are difficult to envisage at home. But beware of copyright! See http://www.sculpteo.com/fr/ (you can print from a photo ...)

Other possibilities:
An interesting option would be to share such printers in small groups.

Some cyber cafes or other small businesses could also offer this service.

The fact remains that having your own machine at home is an attractive option. Especially for those who have a lot of projects. And it is possible at a low cost with the kits and other 3D printers that you can assemble yourself.

See you

Hello Yves,
yes I feel very new and interesting outlets for this kind of machine.

That of my neighbor resolutely aims at an inexpensive global technique and an ambition to democratize this new type of tool: much cheaper than a current color photocopier.

Initially, the cement hollow proofs are not completely finished: additional work downstream will have to be carried out if the customer wishes "a home finish finished to the nearest tenth of a mm.

We can then imagine a second finishing tool controlled by the same computer and performing machining with a small cutter in the end of the control arm.

To conclude:
for the 3D cement photocopier without injection pump, it is now accepted that the basic machine is inexpensive to manufacture, it is reduced in size (1m x 1m x 1m) for medium-sized tests = 2 meters maximum for example, however, there is a need for a finisher option if you want very faithful proofs (in size and surface condition) ....

or we have the finishing touches by hand = "sculptor mode"

the resolution achievable with the melted filament technique exceeds all my expectations:

These mini-busts were printed on an Ultimaker, a 3D printer optimized for speed: http://blog.ultimaker.com/

Hello Petrus,

Quite 'impressive' these achievements.

Seeing that there is no longer much doubt, the rapidity of evolution suggests cheap machines with very interesting performance in a very short time. One year, two maybe?

It's revolutionary !!!

According to a statement published last week on its website, the European Space Agency (ESA) is currently studying the possibility of building a base on the Moon using an unexpected process: a 3D printer which would use materials present on the spot.

Since the 1960s, the Moon has been the subject of numerous explorations before being gradually abandoned in favor of other more distant planets. Today, however, it has returned to the center of attention with particularly ambitious projects, including that of building a moon base. A place that could then be used for future missions to extend the exploration of our satellite. But there remains a problem: how to build such a structure on the Moon?

It would of course be possible to bring the pieces one by one but this would depend on their size and would require time before the base was completely completed. Not to mention that bringing materials to the Moon would cost a fortune. At the request of the European Space Agency (ESA), several industrial partners and certain renowned architects have therefore worked on a rather unexpected alternative: build this lunar base using a 3D printer!

Build a solid and resistant base with lunar materials

This process works a bit like a conventional printer except that it proceeds layer after layer. This then allows him to superimpose them and ultimately create a three-dimensional object from a virtual model. "Terrestrial 3D printing technology has made it possible to produce complete structures," explained Laurent Pambaguian, head of the project for ESA. "Our industrial team therefore sought to know if, in the same way, it could be used to build a lunar habitat," he added in a statement from ESA.

In other words, the question is therefore whether the 3D printer could directly use lunar materials to create and assemble the famous base piece by piece. To assess this possibility, the architects of Foster + Partners who are participating in the project have designed a kind of dome with a wall capable of playing the role of a shield against micrometeorites and space radiation. It even contains an inflatable device to house the astronauts. On the structural side, the architects were inspired by the bones of the birds to obtain something solid but not too heavy.

The base, produced as a demonstration, was imagined from the properties of the lunar soil but still required a 1,5 ton block to be set up. "3D printing offers a potential way to make it easier to set up a base on the Moon with reduced logistics from Earth," said Scott Hovland of the ESA spaceflight team before adding : "the new possibilities that this work opens up can be considered by international space agencies as part of the development of the space exploration strategy".

A construction simulation on Earth

However, the experts are continuing their work this time on Earth. The group of specialists at Foster + Partners is currently working on the development of a structure capable of withstanding extreme climates on Earth. This structure would then serve as an exercise in the construction of a lunar base using, there too, materials available on site. To best imitate the lunar soil, specialists plan to use a sand-like material to which various components are added.

“First, we need to mix the simulated lunar material with magnesium oxide. This turns it into 'paper' that we can print with. Then for our structural 'ink' we use binder salt which converts the material into a rock-like solid, "explained Enrico Dini, founder of the British company Monolite, which is participating in the project and supplying the printer.

For now, the printer is able to build 2 meters per hour, but those of the next generation will be able to reach 3,5 meters per hour, which will allow them to build a complete building in a week.
