Invention Summary


Scientists at NDSU have developed a process to produce the most realistic alternative to human bone available by combining engineered materials with specialized additive manufacturing (3D printing). High resolution manufacturing accurately reproduces physical and mechanical properties of the desired bone, including the contour of cortical ‘hard’ bone and intricate structure of trabecular ‘spongy’ bone.

By adjusting the engineered materials and process, replica bones can be manufactured to closely simulate behavior of bones from people or animals of either sex, different ages, medical disorders, or even a particular patient. By tailoring geometry and performance to customer specification, these devices will meet needs ranging from repeatable lab tests to personalized healthcare of a specific patient (e.g., practicing a complex surgery using these realistic bone surrogates).

The artificial bone construct can be used in the testing and development of new surgical procedures, ballistics testing, implantable devices, etc., and the artificial construct closely approximates the physical and mechanical properties of one or more components of a skeletal system. 


  • Artificial bone surrogate properties can be tailored to meet desired design specifications
  • Training tool for training doctors and dentists doing bone surgeries 


The technology combines advanced materials with 3-D printing for realistic bone feel and flexibility to tailor characteristics for an artificial bone.
