Printing ABS with Robo R1

Good afternoon everyone.
I do not currently have a 3D printer, although, I'm extremely close to purchasing the Robo 3D.
The only thing holding me back is the capability to print with ABS plastics.
I feel that compared to the Flash Forge, the Robo has many advantages. (Build area, quality, price, etc.)
The one thing the Robo doesn't have that the Flash Forge does is an enclosure, which from what I've learned, is very crucial to printing ABS.
Does anyone have any experience with printing ABS on the Robo R1?
I've seen online people have created enclosures for the Robo R1, and I've seen one individual also sells his own enclosure for the unit.
Any information that will settle my mind would be very helpful, and much appreciated.
Thanks.

 

It prints ABS just fine, but not large parts. Large pieces will warp up on the ends.

I printed this in ABS on buildTak material on my robo3d I had a little warping on the corners.




Printing with a raft can help a little, but it warps even on a raft. I do not have the enclosure.

I don't use ABS much anymore though its too finicky. PETG ( I use ESUN brand ) prints way better/easier and doesn't warp..so that is what I have been using. And it has a higher melting point thatn PLA and is not brittle like PLA. I don't see the need for ABS anymore really.

 

Thanks a lot for the response.
How would I be able to prevent that warping?
If I had an enclosure, with the unit in the warm room, would it still warp?
Thanks again.

 

I still get warping in a fully enclosed Replicator 2 that has been modified to have a headed bed. So I don't know.. ABS is annoying.

 

Wow. That's very surprising..
It's a bit concerning though, because the main material I'm hoping to print is ABS.
I realize there are other materials that may be easier to print, but ABS has an engineering grade of strength I need.

 

There is lots of other materials with ABS strength minus the annoyances of printing in ABS.

I used to want to print ABS as well for the strenght. The only reason i use it now is because im trying to use up my leftover spools. I'm really liking PETG it prints at 235 deg. wont melt in the sun like PLA.. its way stronger than PLA as well..flexes before it breaks so its not super rigid which is a drawback sometimes.

 

Thanks for the chart and information.
I just need a very strong material for the items I'd like to print.
Are the alternative, high strength materials much more expensive than ABS?
Once again, I've just started looking into 3D printing in my free time the last month or so.
I really appreciate the guidance and help.

 

Depends on the material.

PETG is about $25 a spool ( http://www.amazon.com/filament-1-75...UTF8&qid=1450666213&sr=8-3&keywords=esun+petg )

PLA/PHA is about $35 ( http://www.printinz.com/pla-pha-filament/ )

Colorfabb XT is expensive

PrintedSolid sells a bunch of filaments you can compare the prices. Looks like they are out of alloy 910.. i'm not sure how much that stuff is.

Just looked up some videos and read some information on the PETG. Amazing. What a great filament. Stronger than ABS, and it's not as temperamental as ABS.
Does PETG require an enclosure?
Does anyone have PETG printing experience?

 

PETG doesn't need an enclosure, it prints easy like PLA does. Though it prints at a higher temp. I print it at 235 degrees. ( PLA I print at 200ish ). I doesn't really need a cooling fan( PLA Does ) either, though sometimes I turn it on.

I printed this halo helmet in Orange ESUN PETG.

Wow. Run into any issues whilst printing?
Looks like my issues here are solved.
I've ordered the Robo 3D R1 off of Amazon, and it should arrive in the next few days.
Christmas present to myself LOL.

 

Not really. the PETG oozes a bit compared to ABS/PLA. so sometimes I get a glob buildup on the nozzle. Still working on figuring out how to reduce that. Hasn't been a big problem though.

 

One reason I like ABS is the ability to cold vapor-smooth it.

As far as I know, there's no other commonly available plastic in a range of colors that can be easily smoothed like ABS. If someone can prove me wrong, please do so...

 

According to Amazon, PETG filament is only $3-4 more than ABS spools. It's also available in every color that ABS is available in, at least from what I've noticed. Seems like the miracle filament in my case.

 

Yes, but I can't use a commonly available and somewhat non-toxic chemical to smooth it and make a print that has no perceptible layer ridges.

Am I wrong?
