Looks like the Lix 3D Printing pen has run into some issues. First of all, they seemingly were not ready for the huge number of presales they received from their Kickstarter campaign. This has forced the company to push back delivery dates for backers considerable. The second issue involves the design of the pen itself. The company says that the engineering team they hired to get the pen ready for mass production has found issues, and will need to change the design a bit. The exact changes are really anyone's guess at this point. More details on the dates when the 3D pen will ship to backers, as well as additional information as to why this has happened can be found here: http://3dprint.com/4281/lix-3d-pen-problems/

I would be interested in hearing opinions from Kickstarter backers on all of this.
