Here’s a print with support material. The overhang at the chin and nose is would not be possible to print without support material. Support is printed from the same material as the guy is printed from. Removing it takes a bit force (I have to find a way to make the support less dense) and leaves some spots, but it works.

I’m sure that with the Low profile of the extruder mount, you could add support for two extruders for different materials or different colors.
Good work! it looks good just keep it up =]
Can’t wait to see it printing my parts!!

The reprap folks have made support material by running much less plastic through the extruder, leaving very weak bits, but strong enough to hold up the overhang.
nice print! can you post a link to that 3d model?
What pleasantly surprised me, was that the curved parts on the top look really smooth. Which is a good thing.
For that, these pictures are actually really interesting. Could you post them in higher resolution?
Here are some high res pics.

There’s a lot of room for improvement, specially with making the support material less dense. The spot on top of the head is due to the print head not moving away when it was finished printing, this one is fixed in the Replicator G 022 release already.
> I have to find a way to make the support less dense…
For some reason MBI sets their support flow rate at 2.0 in the profiles they ship, which really doesn’t make sense to me.
To change the density, change “Raft\Support Flow Rate Over Operating Flow Rate” in skeinforge to some value less than 1.0. With the rig I saw Erik showing off this weekend, I’d start at 0.5 and see how that works. Or even 0.25, if you’re feeling adventerous.
This should drop the extruder speed down to 1/2 the normal rate (or 1/4 normal rate for 0.25) but at the same feed rate when printing the supports, which will result in much less-dense plastic. I think your goal is probably to keep dropping it down until the support structure starts getting unstable – the lower you can get this ratio, the better (better = easier to remove, less cleanup, etc).
I have no idea how/if this will work with the 5D stuff. Still trying to wrap my brain around how all that works..
I am interested in purchasing your unit for a specific project. I am concerned since I need the parts in ABS if your machine can handle it since you do not have a heated bed. You tell me but I would like to send you some STL files and see if you can print them in ABS.
Are there good clear examples of an ABS print? How do you get around the no heated bed issue with your unit when printing in ABS?
