Digital Media Lab
3D Printing Overview
3D printing allows you to create physical, three-dimensional objects from digital files. This service is available in Rettner 201 on River Campus. Prints are charged at a per-gram rate to a URos (Flex) account.

The following 3D printers are available in Rettner Hall.
Cube 3D Printing Service
The Digital Media Studies program has launched a public 3D print service in Rettner 201 (the Digital Media Lab). Faculty, staff, and students with the ability to pay using URos/declining can ask the Rettner Help Desk staff to print a 3D file at a reasonable cost, whether it's related to coursework or not.
Stratsys UPrint SE Plus
This machine is also a Fused Deposition Modeling (FDM) unit, this time printing ABS plastic. Resolution is comparable to the MakerBot (layers about twice as thick). This machine can print print more complex geometries using a soluble support material. This is then removed by soaking in a high-pH solution using the WasWash unit. Printing cost is approximately $5 per cu. in.
To schedule jobs on this printer, prepare your model as an STL file and contact Jim Alkins in the Rettner Shop office to make arrangements for printing and washing.
For more information visit the Stratsys UPrint website.
Stratsys UPrint Quick Facts
Location: Rettner 106 (Fabrication Studio)
Material: ABS plastic in expensive proprietary spools
Support: Yes, remove in high-pH WaveWash unit
Build size: 203 x 203 x 152 mm (8 x 8 x 6 in)
Layer thickness: 245 microns (.254 mm, .010 in)
Software: Proprietary Dimension Catalyst EX software does slicing and toolpathing; very few user-configurable parameters (discuss when submitting job)
Cost: Approx. $5 cu in
Speed: Not fast - overnight for anything reasonably large or complex, plus time to wash (depends on geometry)
Stratasys Objet 30 Pro
This is our highest-quality but also most expensive and least accessible printer.
It prints a photopolymer gel that is cured with a laser. Printing cost is $1 per gram of liquid material. Layer resolution is usually 28 microns (a thousandth of an inch). It can print rigid opaque as well as a transparent material and a simulated polypropylene material. It can print a “glossy” finish on top surfaces. We do not stock all materials, and changing materials is very expensive.
To schedule jobs on this printer, prepare your model as an STL file and contact Jim Alkins in the Rettner Shop office. Jobs for the Objet must have both a suitable application context and a demonstrated need for the material properties of the printer. In-person interaction with the operator will likely be necessary when printing on the Objet.
