A third of the cost come from the hardware
two third of the cost come from the electronic (mainboard, stepper drivers, motors, etc.)
I barely included the time I devoted to this project but here is a small participation for it
Printing the parts or buying them from the community
A Laser cutter for the Makerspace !

After a first version and 30 prototypes I'm looking to make a second batch for the version 1.1. And to make it available for more people I need you to be a part of it.
3D-Printer, RepRap, what's all about ?
3D-Printing is an additive manufacturing process : layers of plastic are successively laid down to produce objects relatively quickly. This allows to produce some pieces that would have been difficult to make with conventional processes (machining, injection), and contrary to molding there is no tooling.
Hence it is often compared to our traditional printers : with a digital file and a raw material we can make all sort of things at demand (fused plastic replacing the paper+ink), simply by changing the file sent to "print". We are still far from the Star Trek Replicator, but on the way...
The technology of 3D-Printing is not new, but there have been a big change around 2006 : the team of the Dr. Adrian Bowyer (Bath University, UK) made the firsts RepRap (Replicating Rapid-prototyper) - a 3D-Printer which can prints some of it's own parts.
However, the beauty of this invention resides not in itself but rather in choosing an open-source license (learn about it here reprap.org/wiki/Wealth_Without_Money ). Quickly a vibrant community arose around this project, the propagation became exponential and variations started to flourish (see the RepRap Family Tree reprap.org/wiki/RepRap_Family_Tree).
A technology which was only accessible to industry and big companies is now at hand of any enthusiast tinkerer. While 3D-printing makes it's way in schools, garages and homes, people start to make or try lot of things by themselves, useful or not, sometimes truly practical when it came to fix stuff or for custom-made parts. Looking at sharing platforms like Thingiverse, CubeHero, etc. reveals how creative everyone can be... what do you imagine then ?
Descrizione del progetto. Caratteristiche, punti di forza e peculiarità.
Main features :
* Foldable, +/- 4kg
* Made with 20 x 20 mm robust aluminium extrusions, widely available
* Easy to assemble or disassemble, with few tools
* Modular, this point is particularly important, not only to scale/tweak the machine, but also on a long term perspective, unlike machines based on custom cut panels you can reuse the basic construction elements in a newer version or other builds.
* All the electronics are safely enclosed in the base, connected via USB
* Use the same open-source toolchain (firmware/software) as any reprap (Marlin/Slic3r/Pronterface), that run on windows, mac, linux
*Peltier heated bed (fast heat-up), or cold-bed
* 1,75 mm direct drive bowden extruder (instant retract, near-zero hysteresis)
* Use parts shared with other printers design (reprappro hotend, Melzi boards), contributing to the reprap dev. ecosystem
*140 x 140 x 140 mm build volume
Motivazione e a chi si dirige il progetto
For who is this project ?
I firstly aim this project for experienced users, already having a 3d-printer or aware of the personal manufacturing trend, the maker movement, FabLabs, etc. and the potential revolution they represent.
Nonetheless, I designed the FoldaRap to be as easy as possible to build : you need few tools, and there is no distance to check during the assembly thanks to the push-fit strategy, making it easier to build than the previous models.
"You don't own it if you can't open it", by building it yourself you will also got to know how it works in the details, which is useful in case you need to repair or adapt something on the machine (an appreciable difference over plug-n-play/closed machines).
For the 30 first FoldaRaps, we have seen both neophytes and experienced users building one, it took between 4h to 20h to assemble (for a order of challenge almost comparable to a Ikea furniture). So that make me think it is for people who want a cute little printer, that works well in a not so tiny print volume ;-)
The FoldaRap will soon celebrate its first anniversary of printing (project start : 2011/11 - first printed object : 2012/05/24 ) ! And now this model has been replicated several times in the wild !
Obiettivi della campagna di crowdfunding
This time I want to go to a next level and experiment with distributed manufacturing and open-source business models.
By offering mostly kit without printed part it will create a demand that the community can answer, sometimes locally (why ship printed parts when you can have them made near you?), but I also asked for people who are interested by this experience to supply printed part for the complete kits, in this case we can think of it as a quality certification of the producers and their machines.
Distributing the production over the community is also a way to scale up with agility, allowing me to supply a greater number of kits (which is good for bulk ordering) while sharing the profit with others.
The next level experience is about a distributed low-cost 3d-printing service that I'm setting up with a team (3dprintskin.eu), because even if the machines are more accessible than before, there will be always people who just want their model printed, while those who are most interested by the RepRap could help them and make an additional revenue from it.
Think of every FoldaRap as a potential franchise, replicating the machines but also the economic model we imagined, which let a very good share for the contributors, but this is another story ;-)

I'm Emmanuel Gilloz, designer-geek-idealist : about.me/emmanuelgilloz
When I was a child I wanted to be a tinkerer and change the world.
Today I'm part of the Makers movement, and this enthusiastic generation who is building a better world, in order to progress each day toward the ideal of a more distributed and cooperative society.
Instead of objects, I design environments/tools that allow individuals to create their own solutions. Thanks to this original approach I could met a lot of great people and contribute to the creation of several FabLabs/Makerspaces in France and Africa.
About my implication in the RepRap project (reprap.org/wiki/User:Emmanuel)
I heard about it in 2009, somewhere on the Internet... One year later, after having read a lot of things and saved some money, I started to build a Mendel (the second RepRap generation at this time), but it was way harder than today : it took me 6 months to finish the machine and print my first object. Later I had the occasion to build many more machines, Prusa, Orca, Huxley,etc. (spending hundreds euros in that hobby).
Following a discussion with a friend I started to map the complete RepRap genealogy, by curiosity and to show the power of the community : the RepRap Family Tree (with more than 400 we are now trying to automate its generation while it is still made by hand for the moment).
And then as you now know I added my own version with this foldable reprap ;)
I choose to limit the first batch of FoldaRap to 30 machines (www.ulule.com/foldarap/), to lower the risks and cope up with the demand by myself.
After that experience, with the strategy of p2p manufacturing and the team at 3DPrintSkin, I'm now confident to go a little further, and I'm aiming for 50-100 kits (for which I already have most of the materials as you can follow here reprap.org/wiki/FoldaRap_Batch2 ), but to make it real I need you : support us, spread this campaign, join the movement !
Keep sharing !
