It's nice to see shares of Stratasys (SSYS) and 3D Systems (DDD) finally moving up after being pummeled over the last several months. Today Stratasys released their quarterly earnings and they beat on earnings per share. This has led the entire 3D Printing sector to move up. Stratasys shares are up about 14.4% today alone.

Any thoughts on where things may head next? Is HPQ a good buy at these prices with their entrance into the space planned for later this year?
