Paris-based medical device company Biomodex is opening a factory in the Boston area in the next year to produce replicas of individual patients’ organs using 3-D printing.

The company announced Thursday it has raised $15 million for the 4,500-square-foot facility, from European investment firms Idinvest Partners and InnovAllianz.

The synthetic organs are used by doctors to “test drive’’ procedures on patients, said Carolyn DeVasto, Global Vice President of Commercialization at Biomodex. The companies uses medical ­images of the organ that is to be operated on, such as a heart with a structural defect or a brain with an aneurysm, to design the ­replica.

Right now, products are in the testing stages and Biomodex is running independent studies in which surgeons rehearse their procedures on the replica organs before performing the real thing.

“They practice with these printed organs much like they would’’ a real patient, DeVasto said, “to give physicians as lifelike an experience as possible.’’

The startup plans to hire 10 to 12 new employees from the ­United States in the next year, with about half expected to work at the Boston facility.
