Between the two printers, high-resolution models ranging in height from a few millimeters to just under two feet can be produced.



Computer-Aided Engineering

The IBRC employs the use of several computer-aided engineering (CAE) softwares across multiple research projects. Finite-element analysis and multibody dynamics are the most common types of CAE used on IBRC research projects. LS-DYNA and MSC Adams are two of the IBRC’s most commonly utilized software packages.


Faculty, staff, and students of the IBRC have access to mathematical software, such as MATLAB, capable of modeling, analyzing and, calculating symbolic or numerical data. Statistical analysis software, including SAS and JMP, is also available to individuals working in the IBRC. These software packages are made accessible through the Ohio State University site licenses.


Researchers in the IBRC use Solidworks CAD software to design and prototype parts for test fixtures and full fixture assemblies. The IBRC also has a license for Mimics, which allows users to create 3D models of bones from CT scans of real subjects that can be imported into CAD or CAE software or 3D printed.
