Machining and Prototyping Core

The Machining and Prototyping Core Facility involves the use of three major facilities within the University of Nebraska at Omaha Biomechanics Research Building:

Machine Shop
Design Studio
Additive Manufacturing Laboratory

The most basic function of the Core is to provide services that utilize these spaces and their personnel and equipment. These services are for professionals in the University of Nebraska system, the local area, but also for people outside our state to progress their research or other projects.

This core can design, prototype, manufacture and repair, maintain, or install a wide range of devices and instrumentation. Individuals interested in the use of the Machining and Prototyping Core Facility services can fill out a project initiation form.

Machine Shop

The 1223 square foot Machine Shop is equipped with both traditional and advanced machinery that allows for the construction and fabrication in woods, metals, plastics, and unique composite materials. Equipment in the space includes a wide assortment of hand tools, and traditional subtractive manufacturing equipment. In addition to the tooling, several design workstations running the Autodesk Suite, Adobe Creative Cloud, and Solidworks are used by staff and student engineering technicians. The machine shop was also designed for typical prosthetics casting with a plaster modification area with grated, recessed flooring, and oversized fume hood for carbon fiber lamination. The Research Development Engineers have their offices in the machine shop and are available for designing and manufacturing devices needed for research. Primary equipment in the Machine Shop includes:

CAD Workstations
Bridgeport Knee Mill
HandyScan 700
Metalworking Tools
Metal/Wood/Plastic Working Tools
Hurco TM6i Turning Center
Emcomill E350 3-Axis Micomachining Center
GlobalMAX 1509 Waterjet
Fanuc C400iC Wire EDM
Hurco VM10i 3-Axis Machining Center

Design Studio

The Design Studio is a 470 square foot space that is dedicated to supporting student researchers in planning, conceptualizing, design, and basic fabrication for research projects. The studio is equipped with workstations capable with of industry-grade CAD software, simulation, and analysis. Also available to studio users are basic hand tools, power tools, a laser cutter, 9 Prusa printers, collaborative creative spaces, and functional prototyping layouts.

Additive Manufacturing Laboratory

The Additive Manufacturing Laboratory includes a primary 675 square foot space for general activities and a secondary 224 square foot space designed specifically for printing metal components. The laboratory is equipped with a wide range of 3D printers, ranging from industrial to commercial grade, and capable of printing many different polymers and metals. Primary equipment of the Additiive Manufacturing Laboratory includes:

ProX DMP 320
Connex3 Object 260
Raise3D Pro 2 Plus
uPrint SE Plus
Fused Deposition Modeling (FDM)/Fused Filament Fabrication (FFF) 3D Printers
Sintratec S3 Selective Laser Sintering 3D Printer
