Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of 3-D printing and services company ExOne (NASDAQ:XONE) soared as much as 15% after its CEO Kent Rockwell announced that his company was targeting gross margins of 50% within three years, according to a Reuters report.

So what: As part of the company's plans to ramp up annual revenue output to $100 million, ExOne is planning to open three new production service centers this year: one in the U.S., one in Japan, and one in South America. ExOne plans to use the largely unmet 3-D needs of Asia and South America as its jumping-off point for rapid growth and its push toward 50% gross margins, putting it more in line with its peers Stratasys (NASDAQ:SSYS) and 3D Systems (NYSE:DDD) which both reported gross margins of 51% last quarter. However, Rockwell was also quick to note that ExOne is an industrial printing company through and through and has no desire to enter the consumer 3-D printing market. (Breathe a sigh of relief, 3D Systems shareholders!)

Now what: Again, these are ambitious plans for a company that's made a grand total of 21 3-D printers in 12 quarters and turned its very first profit last quarter. I fail to see how expanding this quickly will go off without a hitch or without having expenses zap any chance of profits over the next few quarters. I don't disagree with CEO Kent Rockwell that Asia and South America are regions of immense opportunity, but I'd be extremely cautious with a company still very wet behind the ears.
