>From the article: "The standard version of their Freeform fabricator –
or "fabber" – is about the size of a microwave oven and can be
assembled for around $2400 (£1200). It can generate 3D objects from
plastic and various other materials. Full documentation on how to
build and operate the machine, along with all the software required,
are available on the Fab@Home website, and all designs, documents and
software have been released for free."

I've been looking at the Wiki and I don't see any instructions on how
to replicate the Fabber once you have one built, but that IMO would be
a very cool thing to do.

Hmm, the "reprap" that they also link to seems interesting as well.

I lurk on this list.  Are you interested in building one?

David,

I did. I am. I will! But Sebastian's directly involved :)

Is a fellow Canadian considering building one?

I'd seriously consider making PCBs for it. If we fab'ed them with Golden
Phoenix, they'd be in the couple-of-dollars range, cost-wise...and folk
could populate as desired (such as: buy FTDI chip if you want USB; buy
MAX232 clone if you want serial).

You'd want someone-other-than-me doing the PIC coding, though ;-)

Seriously, though, I'm pretty motivated to do this as I've been setting
aside money for a Sherline mill. If there's even a handful of people who
want to go guerrilla on this, that'd be fab (pun intended).

Sebastien,

You rock!

Despite my jokes, programming a PIC isn't an issue. Although I'd be inclined
to re-invent the wheel and use an SX chip as that opens up people to using
SX/B[asic] -- bigger potential audience than us PIC folk.

Reading through things it does seem like the extruder head both crucial and
the biggest stumbling block. But are the fab'ing materials also hard to
source?

Are you able to provide any pointers to someone myself (and others) could
pay to fab one?

LEGO is interesting to me and shouldn't be underrated!

Thanks again.

I dunno.  The devices are somewhat interesting, but it seems to me
that there's a pretty big gap between a three-axis nozzle that can
extrude 'stuff' and a really useful "fabricator."  Otherwise people
would be adding nozzles to existing 3-axis machines (CNC mills, routers,
etc are all pretty old hat) at a furious rate just to jump on the
latest high-tech buzzword bandwagon.  Playdough, hotglue, and silicone
are easy and obtainable, but I gotta wonder whether you can really make
anything useful out of them at reasonable speed.  The fancier high
tech photosensitive or quick-hardening resins used in the commercial
3d fabricators are ... far away in price, shelf-life, and usability.

I'm familiar with the general issue from dealing with mechanical PCB
etching.  I have an LPKF PCB router, which I find useful but rather
limited, and expensive to run.  LOTS of people are off trying to build
similar things on a budget, and I look at what they're doing compared
to what the LPKF looks like (or their main competitor, T-Tech) in terms
of tooling, rigidity, software, and so on, and sort of shake my head.

It's a lot of work to end up with a toy that can make toys.

(now, some neat software is likely to come out of the efforts,
maybe...)

It sounds like a plan.  I'm supposed to be the one setting up the webforum for
RepRap users, and a bunch of them will want in on it too.

I'll drop this list a line in a day or two once that forum is set up.

Not really.  We need thermoplastic in a filament form factor.  Luckily,
there's already an industrial application of this; plastic welding rod - a
soldering-iron like device that squirts melted plastic into and onto plastic
objects that need to be repaired.

We can buy plastic welding rod from manufacturers or pay them to process small
lots of plastic into filament, if we're interested in a plastic they don't
carry.  Right now it looks like we'll be use polypropylene and ABS a fair
bit.  We'd like to figure out how to process recycled objects and virgin
granules into filament ourselves - that's something of a medium priority.

There will be a bunch of loaner machines floating around.  The user rules will
probably be something like "You can use this RepRap to make your own RepRap,
as long as you make another loaner machine as well."

I think we'll also evolve a cottage industry of RepRap machine sellers and 3D
printing job shops pretty quickly.  The machine selling side of things
probably isn't going to support very high margins - maybe you can sell one
laying hen to a guy for $1000, but if they only cost $500 to make, he might
just turn around and start selling them to the market at $600.

Agreed.

Happily, I don't think the user agreement on Lego sets forbids the user from
using them to make a rapid prototyper that can be used to make legos.

Hmm, having had a look at the web page, I can see "yet another" project
coming up.

Bootstrap should be easy - they have one of the powder printing machines
here at work ....
