This powerful 3D printer uses multiple colors and materials simultaneously to produce high quality parts with smooth surfaces, fine details, and a wide range of material properties. The Objet350 makes it easier than ever to produce a showcase-worthy prototype with flexible parts or attractive colors. Support material ensures designers don't need to worry about positive drafts, holes in sidewalls, and other manufacturing details.

How to Start

  1. Read the PolyJet 3D Printing Guidelines and 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 DesignTinkerCad, 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.
  2. Using your prefered 3D Modeling Software, export your 3D Model as an STL file.  As a convenience we offer a tutorial for Exporting STL Files From Solidworks, and a tutorial for Exporting STL Files from CREO.
  3. Determine the volume of material (in cubic inches) of your part.  If your software can't do that, then come in to the lab and follow our tutorial on Using Insight To Find STL Volume.  Alternatively, you can use the free online Netfabb Cloud to calculate volume in cubic decimeters, and multiply by 61.02 to get the volume in cubic inches.
  4. [OPTIONAL] If you need to scale your part before submitting it, then come in to think[box] and follow our tutorial on Using Insight To Scale Your STL File.
  5. Upload your STL file using our PolyJet STL Upload Form.
  6. WAIT.  You will receive a confirmation email within 72 hours, to verify your submission was received.  Then, you will receive another email when your part(s) are ready for pickup and payment.  Expected turnaround time is 5-7 working days.  Parts are generally run first-come first-served, however sometimes jobs are run out of order, for a variety of logistical reasons.  Please be patient and wait for the email.

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 0.0012 inches.  The resolution of finished parts on the Objet350 is 0.0012 inches, so increasing the STL resolution much beyond this won't result in increased part resolution.


The materials used are selected proprietary rigid opaque and rubber-like plastics. Costs are based on the total number of cubic inches of modeling material your part will use, with rates published below (see explanation of pricing rates):

Objet350 Material Prices:
Material Slice Height Regular Price Undergraduate Price
Photopolymer 30 microns (0.0012 inches) $50.50 per cubic inch $14.75 per cubic inch

* Regular price is a guide price only, actual cost may vary depending on complexity of build.  Contact Dr Malcolm Cooke (mnc@case.edu) with questions.
