well, if this thing will fly, it is due to (artificial) demand from US traders, not due to fundamentals.
They just announced a loss of "at least" 2.5 million Euros for 2013 - twice as high as expected.
Regarding their 3D printing activities, the CEO says that their printers are not state of the art and are thus not cost-efficient.
They will have to invest about 10 million Euros into new machines in order to get back on track. They don't have 10 million Euros, thus they will have to ask the market for it; this means dilution.
The stock price dropped 15% after their announcement on Monday, so I think the market got it right.
Anyway, good luck.
