A NEW printer???
On Wednesday Bre revealed MakerBot has a new printer in the works. 1 Frankly, I have a tough time imagining what a new printer would be like. 2 With an Automated Build Platform, which incorporates a heated build surface, and a MK5 Plastruder you’ve got just about everything you could want out of a 3D printer.
I’ve been really impressed with my MK5 Plastruder. I’ve been pretty lucky and rarely have filament jams, so I haven’t seen any improvements going from a MK4 to the MK5. However, it’s given me a really smooth, even extrusion. With my MK4 I noticed very slight imperfections in the ABS rafts and layers – like small bubbles and imperfections in the extrusion every few millimeters. With my MK5, these have been almost eliminated. I’ve also noticed that the minor blobs that used to occur when the Cupcake raised the Z platform have gotten smaller. I haven’t made many changes to the Skeinforge profile, so I tempted to attribute this improvement to the new plastruder. Perhaps one of the coolest improvements is the ease with which I can now swap filament. The MK4 system for pulling out a filament required me to slowly back the filament out using ReplicatorG. The Paxtruder-inspired Delrin plug can be loosened, filament yanked out of a warm plastruder, new filament jammed in, and the plug tightened back up in 10-15 seconds. I can definitely tell you this makes me far more likely to swap out colors. In fact, I’m tempted to try swapping out colors part way through a build, just to see what happens.
Unfortunately, I haven’t had a chance to fire up my heated or automated build platforms yet, so I can’t comment on their utility. However, I’m keenly aware of just how much even a minor temperature increase can improve a build’s quality. I’ve noticed that after about two print jobs my acrylic build platform is slightly warm to the touch. This might be due to having a few warm layers of plastic on it – or might just be due to the slightly increased ambient temperature inside the Cupcake caused by the warm plastic, power supply, and from the plastruder. In any case, even this slight temperature increase has been enough to cause a second and especially a third print job to noticeably more flat than preceding print jobs. Having a print bed that gets more than just slightly warm must be pretty great.
I’ve never wanted or needed to print anything larger than my current build size. Besides, that would also increase the build time. I’m just not that patient. 
So, just what the heck could a new printer possibly bring to the table? Or, more importantly, what would you want to see in a new printer?

I would like the idea of a photo developer or photo plotter for circuit design to get .5mm between pins for 100 & 64 pin quad flat pack surface mount chips.
A larger printing airea would allow for larger circuit boards. I think a blacklight and pixel mask might allow it to work…
A in hopper and out hopper for stuff to print on or blank boards to be pulled in would be great.
A non porous cnc would make more sense to me even at a larger cost & higher tolerances for things other than printing.
Electrochemical Machining that could be considered reverse electroplating that would require liquid and hoses & large relays then the cupcake can cut metals.

We’ve got the cupcake – now I want the WeddingCake. We need a big guy.

In the same way Apple released the Apple I for the hobbyists, Makerbot Industries need to make their Apple II – the bot for everybody!

Multiple tools/materials switching would be my personal dream.
Could a printer be built to automatically swap extruder/tool heads? If a machine could effectively switch modes between plastruder, frostruder, router, soldering tool, or whatever, we could start producing much more complex parts and a greater variety of objects, I would think. Of course, the whole system would get dramatically more complicated at that point.
I’m sort of mentally picturing a much more developed Z stage, that can take a new print head off of a rack of compatible print heads to switch tools and/or materials when needed. I guess I’m picturing a move to a more ‘personal factory’-like printer over time. I know that’s been a direction many people have wanted to go with RepRaps.
Our ability to work in lots of materials is, to me, the strength of FDM printing over other methods. It has its drawbacks; overhangs, warping parts, resolution problems, blobbing/strings, slower production, etc. But it isn’t hard for us to print in strong materials or choose the material that best suits the job, so I’m interested in exploring that and seeing just how far that advantage can be stretched. I’m just getting started with 3D printing though, so it’ll be awhile before I can try to make any major contributions to getting there.

Hey, now it’s in the store! Looks interesting, mostly the fact that it’s BUILT for automated home-manufacturing is awesome. More upgrades to come I’m sure, I’m gonna wait until there’s at least some of it I can print and then I’ll just buy what I can’t X3 (Perhaps donating what I save by printing)
