As the increase in 3D printing popularity grows, so does the list of manufacturers that build them.
Since their inception in the early 80s, they have become smaller and more affordable, which has appealed to hobbyists around the globe. There was one drawback that impeded their growth in popularity -- initially there was "some assembly required" in order to use them.
Not all users of 3D printers are adept at soldering or have limited building/assembling skills that were required for early models, such as Makerbot's Cupcake CNC machine or the RepRap (notably the Darwin and Mendel models). It is with this premise in mind, along with feedback from users of the previous model, that Lulzbot has developed and released its new 3D printer dubbed AO-101.
"Invent it, Create it, Produce it" is the motto Aleph Objects associated with the new printer, which makes the process of manufacturing prototypes and other creations easier for the average inventor. In essence, the AO-101 is an upgraded AO-100 based off of user feedback, and features the same overall design and sturdy frame (you can actually stand on it) of the 100 but incorporates improved electronics, sound reduction, and software.

The AO-101 upgrades over its predecessor aren't that extensive and feature pre-assembled installed RAMBo (RepRap Arduino-compatible Mother Board) electronics, a 12V DC 16A internal power supply (accepts PC power supply type plug), Budaschnozzle 1.2a hot end with available nozzle sizes from 0.25mm to 0.75mm, GT2 16 tooth pulleys, revised feed-tube, and filament spool-mount. The machines build volume has stayed the same as the 100s at 200mm x 190mm x 100mm, as well as its overall print speed at 200mm/sec. They have changed the Y belt tensioner so that it is adjustable, revised the Z-axis so there is less wobble while printing, and incorporated an aluminum heat tray.
The printer also comes with an SD card that has the needed drivers and software pre-loaded (you may want to check Lulzbot's website for the latest revisions). They also were able to fit the whole set-up, including tools, 5 lb of free filament and replacement parts into one single box for shipping over the multiple boxes required by the AO-100.
The price for the Lulzbot AO-101 comes in at $1,725 US, which is decent for a pre-assembled printer of this quality. Others on the net have pointed out that the AO-101 is actually just a MendelMax variant that can be had at a reduced cost, but there is some assembly required. On the other hand, the 101 includes a set of tools, extra bed, a one-year warranty, and on-demand support, which is certainly an advantage for those not experienced enough to build their own machines.
Lulzbot says, "The LulzBot AO-101 is one of the few desktop 3D printers on the market that can print with ABS and PLA plastics. With some simple adjustments, you can print with a wide array of experimental materials like wood filament, nylon, polycarbonate, polystyrene, and glow-in-the-dark materials. "
I am sure they will have to verify the type of materials first. So, I don't think this will be printing stainless steel from spools any time soon.
I am sure it is by weight. Typically, plastic spools go for around $18-35/kg. Every company seems to shy away from guaranteeing length. But, if you know the volume of the part you want to build, it is almost a 1:1 transfer of material.
The price of the device that is given in the articles seems very reasonable for the serious at-home inventor or small shop. Any idea what the raw material costs and/or if you are required to use material specifically made for that printer? Just wondering if the business model is the same as for desktop printer where the hardware is reasonable (or cheap) but they get you on the supplies?
Patents that restrict progress and innovation are not high on my list to celebrate. Any software protection can be side-stepped, so good luck with enforcement. I am sure that "Physibles" will require some level of protection, someday. Right now, it's the wild-west in this area.
The use of such a code would imply someone selling 3D CAD designs with the specific intent for them to be printed, or a private company wanting to protect their designs from "outsiders". This would in no way stop someone from creating their own 3D model on their own. They would just have to work harder.
The patent seems to require that CAD files include an authorization code and that the 3D printer will not print unless it accepts the authorization code. There's no need for such a code on a personal printer. No code-->No infringement.

The 3D printing revolution seems to have a knack for quickly moving technology ahead by way of collaborative effort and even a little friendly competition -- all of course in the name of scientific advancement.
