Actually, the most exciting news from the project is that it has gone from a prototype with poor printing quality to a 3d printer of a great quality to its low cost. Not to mention that it has also inspired dozens of other printers design, including comercial ones like the Makerbot, and can easily be modified to support a lot more printing materials than just thermoplastics (you can even use it to print electronic circuits or food!). In the end, if you know what you are doing, with a couple of these you can print models as good as the ones from the expensive comercial printers.
If they keep innovating at that rate we could see some seriously useful kit in a few year's time.
