Print With Our 3D Printer!

You are here

In line with our mission to promote STEM\STEAM education and showcase new technologies, the Warren County Library has purchased a Rostock Max v3 3D printer.  The printer is currently located at our Headquarters branch, and is now available for use by library card holders in good standing, in accordance with the 3D Printing Policy found on our Policies page.

How does the process work?

First, you must create your design using 3D modelling software and save it as an .STL file.  Most 3D modelling softwares can output in .STL format, but for beginners, we recommend a free-to-use, online software called TinkerCAD.  TinkerCAD is easy to learn and there are many online resources available to assist you: Tutorials on the TinkerCAD website, videos on YouTube, and more.

Once you have your design saved as an .STL file, email the file to us at  We will respond with any problems we see (note that per our 3D Printing Policy, we will refuse to print any weapons, dangerous or illegal items, so please don't even ask!) and let you know approximately when the print will be ready.  We will send you another email when your print is ready to be picked up.  All prints must be picked up within 7 days, and paid for at the time of pickup.

How much does it cost?

The cost is based on the final weight of the print, including any raft and support material. Currently, the cost is 5 cents per gram, although this may change if the price of filament increases.  Unfortunately, we will not be able to give you a cost estimate ahead of time, as we cannot weigh your item until after it's printed.  

Can the library help me design my object?

Unfortunately, no.  We are not 3D design professionals, and the world of 3D printing is new to us.  The library does  plan to offer introductory programs on using TinkerCAD, so take a look at our calendar from time to time.  Also, there are sites on the internet, like, which allow people to share designs they have created, so check these out for inspiration!
