Fab@home, RepRap or MakerBot?


Cysign - Posted on 30 November 2010

As I'm going to build a 3D-printer next year for personal usage, I'm currently not sure which project to join.
I've read a lot about ReaRap and something about fab@home.

My usage will be: creating own stuff in 3D and print it out - what else :D
I'd like to create stuff as big as possible, lige a Rim/Hoop of a drumkit's drum or like a pickguart for my guitar.
But if this would make my 3D printer too expensive, I would be happy with a printing-area of 6"*6"*6" or something like that.

RepRap is cheap and seems to be secure cause it's opto-sensors.
I've read that someone demaged hir fab@home by playing round with the procedural path...damaging it's securing blocks.
Isn't the fab@home secured by circuit breakers?

And I read that fab@home could print chocolate and cheese? That's funny....and perhaps I'd like this option...for any birthday or stuff like that.

But most important is that I've read that fab@home will become able to work as a milling machine?

As I'm thinking of building a small CNC millingmachine as well...it would be perfekt, if fab@home could handle both jobs.
But for my millingmachine it's important that I am able to mill wood with a measurement of 32*6*70cm!
So if I decide to base my machine on fan@home....would I be able to modify it for working with this size?
As I'd like to mill my own guitar...Sounds crazy....but it's my dream :)

Hope you can answer my questions....

so what do I have to change to get the mentioned size?
and how expensive would it approx. be to build an fab@home model 2 with CNC milling support at that size?

I'm a little biased in my answer, but here is my honest assessment.

Fab@Home has a dremel attachment tool and can do 3 axis CNC milling. So if you were considering getting a 3 axis CNC machine, get a fabathome instead. You can use our software for controlling and planning the prints, or you can use the Snap motors program listed on the JRKERR website to use G-Codes to do milling and interface with MasterCAM or other G-code based programs.

Fab@Home has a much larger build area than the makerbot or repraps and can use a wider array of toolheads. Repraps are cheaper in terms of BOM but take a lot more care to build, and take a lot longer to build. Not to mention to cost of getting your initial plastic parts made. If you want something that you can order and use in a day, your options are Fab@Home and Makerbot.

Just search through the Wiki and see what people have done with Fab@Home. And notice that is a lot more than just printing plastic.

Ah, I've read a CNC milling support would be able in the future...didn't know it already works.
But what about the size of workpieces? Could I modify a fab@home for bigger sizes? In fact I'd like to mill my own guitar body and guitar neck when it' done.. see measurement I mentiones before.

btw: thanks for private message....else I wouldn't have seen your answer so fast. Is there a option to get messate after response in this board?
