About

The Technology Lab has twelve 3D printers that are exclusively dedicated to the service of active UTSOA students and faculty. To use them, simply e-mail two things to the Technology Desk: your correctly prepared file and proof that your file has passed a Shapeways test (a basic online test for print-ability). Information about how to prepare this type of file, and where and how to take the Shapeways test can be found in the links below. Once you've approved the cost estimate, you're all set! The Tech Desk staff will follow up with you via email when your 3D print is ready for pick up.

All 3D prints are created with eithe PLA (Raise3D) or ABS plastic (Stratasys). Students may not substitute their own materials. Orthogonal features finer than 1/16" are too small to be accurately produced by the printer and will result in a less desirable final product – especially when soluble support material isn't used. Complex geometries must be larger than 1/16" to print successfully. The maximum size of your print is limited by the interior capacity of the individual printer.


This was printed on a Stratasys 3D printer using ABS model material and soluble support material. The small features were made possible by the use of soluble support material.

3D Printer Information

Raise3D

The Raise3D Printers use PLA filament. Our models have different maximum volumes. If your model requires supports to be generated, the Raise3D printers will use PLA. You must remove the support structures after you receive your final print.

  • Pro3
    • Single Extruder Print: 11.8" x 11.8" x 11.8"
    • Dual Extruder Print: 10" x 11.8" x 11.8"
  • Pro3+
    • Single Extruder Print: 11.8" x 11.8" x 23.8"
    • Dual Extruder Print: 10" x 11.8" x 23.8"

Stratasys

The Stratasys Printers use ABS (model) and QSR (soluble support). Our models have different maximum volumes. If your model requires supports to be generated, the Stratasys printers will use QSR. We will run your print through a chemical wash process to remove the QSR before you receive it.

  • F370
    • Build volume 14" x 10" x 14"
  • 250mc
    • Build volume 10" x 10" x 12"

3D Printing Costs & Estimates

A price estimate will be provided for you upon submission. If you do not pick up your print, you will still be charged the full amount to your What I Owe.

*We're not using this material yet, so any support structures within your Raise3D prints will use PLA.

Time Expectations

Prints can take anywhere from several hours to several days depending on size and complexity. The Technology Lab staff print multiple projects at the same time whenever possible to maximize efficiency, however, you should expect a turn-around on 3D prints in one to two days when demand is normal. During periods of high volume, the queue may delay your print by several days. Please keep this in mind when considering due dates. Tech Desk staff should be able to give you a rough estimate of when you can expect to pick up your print after you submit your file.

Best Practices

  • Use SNAPS and OBJECT SNAPS while modeling to line up objects according to their endpoints or other geometrical identifiers.

  • Join curves and surfaces as you build them.  Keeping things joined as you work will help you know that your objects are truly coincident and closed.  The JOIN command will not work if things are not lined up properly, so this is a good check.
  • Cylindrical features are more accurate when the cylindrical axis is parallel to the z-axis.
  • Make sure that a flat surface is not made up of multiple geometries, which can cause it to print incorrectly.
  • Make sure your file is set to INCHES
  • Every element of the model must have thickness.
