I'm new to the 3D printing scene and I was about to order a Makerbot last week but heard they would be making a CES announcement this week. Any advice from more experienced hackers regarding whether it is worth holding out for this new model with the dual extruder?

I think the dual extruder is cool, but I'm more excited about the larger build volume.

You might consider trying to buy a used Makerbot less than full price, and then buy the new Makerbot in a year when the kinks are worked out.

Do you have a specific target you want to make? If so you should ask on one of the 3d printing forums "would an original makerbot be suitable for _x_".

If not, then an original makerbot would be a good first unit. From what I can tell, great community support which will help you figure out what you need.

As a person who has built their own CNC from a kit, I can tell you that these things are not like "printers for things" as much as they are a really complex tool that you will need to learn how to calibrate and use just like any other hobby.

I've had my CNC for 6+ months and only now am I getting to the point of getting usable (detailed) results from it. Mind you I'm milling PCB's which have a relatively low margin of error, but still.

Machining is it's own hobby (or trade, or profession) and takes time to learn.

No clips of it in action. How does it support a model under construction? Some matrix material? A jig you have to make separately?

How do parts get built assembled, without adhering? What's the resolution? Those examples seem quite coarse/blocky.

Thanks for the advice, any recommendations for the most active community online? The Google Group linked at the Makerbot site seems pretty sparse, as does the Makerbot section at CNCZone.

From my research: it currently has not been possible to print overhangs greater than 45 degrees on models using the plastic extrusion process. I think the dual extruder allows the opportunity to incorporate a water soluble plastic material into the printing process in order to support overhangs.

Reprap-derived FDM printers like the Makerbot use support material that can be removed after the print. This can be emitted by the various slicing software out there.
