NEW YORK (TheStreet) -- Shares of 3D Systems (DDD - Get Report) were rising 5.83% to $15.79 mid-Tuesday afternoon after General Electric (GE) agreed to purchase two European 3D printing companies Arcam AB and SLM Solutions for a combined $1.4 billion.

Arcam, based in Sweden, and German-based SLM will both report to GE's Aviation division.

The acquisitions almost double GE's total 3D printing spending since 2010 at $2.9 billion. The deals add to the Fairfield, CT-based industrial company's plan to increase sales and widen margins using additive manufacturing.

GE has already employed 3D printing processes in products like fuel nozzles for its Leap aircraft engine.

3D Systems, based in Rock Hill, SC, is a 3d printing and print materials company.
