Introduction

 

Quickly iterate your prototypes to verify your designs and catch flaws sooner using this "prosumer" desktop 3D printer. Use this printer to rapidly prototype display or example models. The Ultimaker is inexpensive, easy to use, and unlike the other 3D printers at think[box], you can run it yourself. If you don't need a stronger functional prototype, or the additional accuracy found in the Fortus 3D printers, a Ultimaker may be the 3D printer for you.


How to Start

  • Prepare your design using your prefered 3D Modeling Software (SolidWorks, CREO, Rhino, Alias, Google SketchUp Pro, etc). If you do not have access to a CAD package, consider using one of the free CAD packages like 123D Design, TinkerCad, or the free educational download of Autodesk Inventor. Please note think[box] does not currently offer training on any CAD package, instead it is suggested that you search for online tutorials for your preferred CAD package. Use your home computer, Nord Lab, Reinberger Lab, or another lab on campus to prepare your design. There are only a small number of computers at think[box], and they are to be used for running machines, not preparing designs.

File Format 

 

The 3D printer takes STL files, the most common 3D file format.  When exporting STL files from your modeling software, if you get an option to select a resolution, there is no need to go smaller than 0.001 inches. The resolution of finished parts on the Ultimaker is not finer than this, so increasing the STL resolution beyond this won't result in increased part resolution.


Material

The material used is plastic called PLA (Polylactic Acid). Material properties such as Tensile Strength and Flexural Modulus vary widely with exact composition. For functional prototypes, it is recommended that you use a different 3D printer. Colors stocked include red, orange, blue, purple, white, grays, silver, black, and translucent natural. Visit think[box] to verify your desired color is in stock. If you would like to bring in your own material, please see a think[box] staff member. Final costs are based on the weight of material you use. A student worker will weigh your desired spool before and after you use the 3D printer and calculate the price based on the difference in weight and the pricing rate below:

Technical Details

 

Build envelope (XYZ): 223 x 223 x 250 milimeters (8.78 x 8.78 x 9.84 inches)

 

Ultimaker’s advertised step height is 20-600 microns (about 0.0007 - 0.023 inches). Your results may vary based on the settings you choose and the geometry of your part.
