The Discovery Learning Laboratory has three Dimension 3D prototyping machines: an Elite, a 1200ES, and a uPrint.

These machines are available for student and faculty use when pursuing educational or research goals. We ask questions from time to time about the purpose of the prototype in order to manage this resource.

Steps

1) Export an .stl file from any CAD source.

2) Determine x,y,z size in inches or millimeters.

3) Create a work Order using .stl file and state in the work order the dimensions

Work Order

 

Notes

  • 3D printer files are .stl files exported from any CAD package.
  • The work order should state the physical size and volume of the object to be printed.                   [ie. 2"width x 3"length x6"height and 36in3]. This rough information can be obtained from your CAD model. We use this information to select the machine which will fit your model. Sometimes happens that an .stl export is in mm instead of inches. There is a huge difference between 1mm and 1inch. We use your stated physical size to correctly print your object.
  • Plan on a two to four workday turnaround. Sometimes it is shorter, sometimes longer. It depends on the complexity of the model, work orders and material availability.
  • The plastic material is Stratasys® ABS-M30.
  • Current reported tolerances of the printed model are 0 to +0.010 inch. Inner diameters of holes will sometimes be up to 0.020 inch undersized.
  • Small parts can sometimes be a problem. Something smaller than a thumbnail is not usually successful. A printed layer is only 0.010 inch.
  • Dimension 1200ES: Build table size - 254 x 254 x 305 mm (10 x 10 x 12 in.)
  • Dimension Elite: Build table size - 203 x 203 x 305 mm (8 x 8 x 12 in.)
  • Dimension uPrint: Build Table size - 203 x 152 x 152 mm (8 x 6 x 6 in.)
  • Average cost of printing is approximately $5-$6 per cubic inch. However, we do not charge for the use of the printers... yet. We will be curious about anything bigger than 10 cubic inches in size. Please keep this in mind.

About the lab

The Marquette Engineering program is design-focused and laboratory intensive. Many classroom and laboratory assignments are multidisciplinary and project-based. The Stanley V. Jaskolski Discovery Learning Laboratory provides a fully equipped, on-site machine shop for design and production of prototypes, test fixtures or complex objects. It is a place where students explore the practical aspects of engineering.
