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.

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.

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.
