3d Printing recommendations

Greetings,
I am studying which 3d printer I can get with my budget and found various alternatives, but was hoping someone with experiance can point me in the right direction. So far I am looking at 4 alternatives. I am thinking I want ABS for sure from what I read it is more durable and I am looking to make metal casts from my prints. Can someone help me in the right direction?

Ultimaker 2 https://www.ultimaker.com/p/our-printers/ultimaker-2

Pros--
PlA or ABS
Good Dimensions
Cons--
price a little steep on a budget

http://www.solidoodle.com/
Pros--
nice price
Cons--
Not sure of the quality, I have read a few forums and problems reported with parts breaking

Makerbot 2x--
Pros--
Ready to print
Good Dimensions
Cons--
PLA only
price a little steep on a budget

RepRap http://www.reprappro.com/
Pros--
Good Price
ABS and PLA
Large print area
Cons--
DYI, a little worried about this hehe. None the less I am willing to do it if neccesary.

I would do Ultimaker 2, but I don't think ABS works for metal casting, you would have to recast it in a different material first.

3d Printers

Thanks for the reply,

I was under the impression that this is how they made this spoon, http://www.youtube.com/watch?v=q9rfr30W09c

Any reason to pick ultimaker over RepRap other than it being a diy?

Also I note the reprap has a new model, http://www.reprappro.com/products/tricolour-mendel/

I wonder what quality would this be and if the prints are a decent size? I have a hard time figuring this out from 210x190x140mm

In that video, the print they made was not ABS, I'm thinking that material would be like the strong and flexible material from Shapeways, which is from a very expensive type of printer.

They actually printed the mold and use a metal with a low melting point (the kind of metal you might use for small metal figurines). The other method is investment/lost wax casting which doesn't necessarily work with all materials, though here's a link where they do it with a Makerbot print: http://jason-webb.info/2012/11/lost...ing/#conclusion

The reason I'd go for the Ultimaker 2 is that it's fully assembled, it's fast, and it's capable of printing very high quality compared to other printers of the same type. Unless you really want a DIY printer, I'd go with that and save the trouble of building one because it really can be a pain to build one unless you have experience with that type of stuff.

RepRap is actually a family of printers and there is a huge and active community to support you to build your own.
If well calibrated a RepRap has the same or even better print quality as a professional FDM machine, @hackerspace FFM, where i am active, we print down to resolutions of 1/40 of a mm, items as small as a few mm³ can be printed to specs. Of course this requires a bit of time you have to invest in calibrating the machine and learning the software, but different to commercial systems it can be done.
My routine print quality is 1/10 mm, way enough for all technical purposes i have and even good enough for some artistic stuff.
Cheers
Björn

I´m keeping an eye on the Form 1 line. Those seem to have the best resolution under 5K.

B9Creator is much better

Srek any particular model of the RepRap Family you would recommend? I am still considering it since I would like to learn and I do have some spare time to build it. I was thinking the tricolour since its their newest on Rerap.org

@darthviper107 Wow I had not seen the B9Creator. I wonder how expensive is the resin, and how difficult would it be to attain it here in Costa Rica.

People have been testing out different resins, so you can probably find a supplier that delivers to your country. Though anything that's not been tested yet would need to have the right exposure times figured out for the resin.

How can I get a sense of how much material I should order to start? I am thinking 1 reel of abs and one reel of PLA, https://www.ultimaker.com/products/abs-white. But not really sure if that would be enough.

Depending on what you are planning to do one spool can produce quite a lot of output. I'm printing for about 2 years now and went through less than 10 Kg of filament.

Which are you more interested in and think about this question a lot before you answer, building a 3D printer or 3D printing stuff? Those are two very different goals. For your viewing/reading pleasure.

http://runningahackerspace.tumblr.c...e-have-a-reprap
http://runningahackerspace.tumblr.c...chased-a-reprap
http://runningahackerspace.tumblr.c...nd-buy-a-reprap

If you want to build your own 3D printer then consider one of the RepRap models. If you want to 3D print stuff and you don't really care how it gets done then do not get a RepRap because you'll get burned out and abandon it before you ever print anything nice.

I have been using one of these and I'm very impressed by it. There's also someone else's half built RepRap Rostock on the table next to it and has been for months (hence the links above).

I don't know what kind of experience you had yourself with RepRaps, but @Hackerspace Frankfurt we have quite a few of them and regularly help newcomers with theirs. A RepRap is not different to any other DIY project, if you go after it without any prior knowledge and abilities you will likely fail, if you inform yourself and check resources in advance it's nothing really difficult.
Imo the best chance to get a working RepRap is to find a Hackerspace that does workshops.
You get help, knowhow and in the end a working printer at a nice price.
Cheers
Björn

PS: 2.2K for that PolyPrinter is 1K to much imo.

It's like building computers in a lot of ways. Similar pros and cons as far as price and convenience goes. Not saying avoid RepRap completely, just know it will take time and effort to get it working. Especially for folks that don't have a hackerspace with experienced members for guidance and help. If any of your RepRap guru colleagues come through Dallas in the future ask them to make a stop at the Dallas Makerspace!

Just wanted to let everyone know, I went with a DIY Prusa I3 and its been quite the journey. I had a lot of fun but it was a little challenging, not all pieces matched and there were no instructions so a lot of internet research.

I am glad I did it this way as I did have to learn a lot about everything including electronics, arduino etc.

The quality of the models, is good but mostly mech stuff. Next was thinking of trying for a peachy printer.
