Chris Lau, Kapitall: HP CEO Meg Whitman is set on getting into 3D printing. What does this mean for rival 3D printing stocks?

HP is not planning to make expensive acquisitions, and will leverage what it already knows in the printing business to grow the department from within. Strong starting point Investors reacted positively to a quarterly earnings report that saw HP gain market share in the printing and PC markets. In the fourth quarter, HP generated $2 billion in free cash flow, while net income was $1.4 billion. The company ended the quarter with no net debt.

Entering 3D printing On the conference call, Meg Whitman said HP would enter 3D printing but will do so by finding its value proposition by market segment: "So we intend to play in the 3D printing market … It’s obviously different than paper printing but some of the technology is the same … we anticipate … entering this organically. And what we’re doing is focusing on what’s the value proposition by market segment, whether that be consumer or industrial. What’s the competitive differentiation and we’ve got some very interesting things coming." The efforts will likely not bear fruit until sometime in 2014 or 2015.

In Q4, shipments grew 6% thanks to good results from Ink in the Office. When 3D printing is finally introduced, it will be a smart part of sales, but if HP finds ways to leverage from its existing printing unit, growth could increase rapidly.
