PolyJet 3D Printer - Objet350 Connex3

ATTENTION: The Polyjet printer is currently out of order. We are waiting on support material to come in from Stratasys. There is currently no ETA on its delivery. We apologize for the inconvenience.

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 preferred 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. 
  1. Using your preferred 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.
  2. Determine the volume of material (in cubic inches) of your part.  If your software can't do that, download Autodesk Meshmixer for free to calculate your parts volume in cubic inches.
  1. Upload your STL file using our PolyJet STL Upload Form.
  2. WAIT.  You will receive a confirmation email 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.
  3. Note: All parts will be discarded if they are not picked up within 30 days of receiving a ready for pickup email from think[box] staff.

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, using the rate published below:

NOTE: When material changes are performed, it can result in longer turnaround times, especially for multi-material orders. If you have any questions, email thinkbox@case.edu
