3D Printing

Many online resources exist to aggregate STLs. Here are a few of the most popular ones:

• Thingiverse

• Cults3D

• Printables

• Yeggi

You can also just try googling '[name of thing I want to print] STL file' and see what comes up.

Some of these sites are 100% free; others may allow file creators to charge money for their creations.

When you find a file you'd like to download, you should save it into a folder under your name in the shared 3D Print (H:) drive, which will make it available on all of the Innovation Lab computers. The first time you save you will have to create a new folder with your name.

You may have to extract the zip archive before you'll be able to use the .STL files within.

If you can't find the thing you want to print already online, you can always create it yourself! The lab offers several options, from beginner to advanced.

If you simply want to modify an existing file by cutting in half, hollowing it out, or perhaps combine two files together, the simplest way will be with Microsoft's 3D Builder tool. You can find a basic overview here. 3D builder can also correct file errors that may be present in .STL files downloaded off the internet. It can also enhance the smoothness of files, as seen here with this Stetson.

To create a new object from scratch, you will have to use a Computer-Aided Design (CAD) program. People new to CAD will want to start with Autodesk Tinkercad, a web-based program that's free to sign up for and use. Click Create a Personal Account to get started. 

You can use the built-in tutorials to learn how to build objects out of primitive shapes and negative spaces, and even import your own custom shapes drawn as black and white .SVG (Scalable Vector Graphic) files.

For more advanced CAD users, all of the Autodesk suite is available for free via Autodesk for Education. Just verify your Stetson email address and you will be able to use everything from Fusion360 to Inventor at no cost to you. These are the programs professional product designers use to create their models.

Finally, there are some more unique utilities that can be used to create custom objects. Meshmixer, installed on the Innovation Lab PCs, provides a clay-like experience for more freeform objects, while resources like the lithophane maker can be used to convert images into 3D formats where the thickness of the object matches the brightness of the image.

Finally, if there's something in the real world that you want to be able to 3D print, the library offers three 3D Scanners that can be used to digitize certain types of physical objects under the supervision of the Innovation Lab Manager.

• The Revopoint Miraco 3D Scanner is an all-in-one scanning solution that can even leave the library! This is our newest and easiest to use 3D scanner, and should be your first stop for any 3D scanning project.

If there is a project that the Miraco cannot handle for whatever reason, it's possible that our two older 3D Scanners may be up to the challenge.

• The Einscan turntable scanner works for objects between 1" cubed and 8" cubed.

• The Artec handheld scanner can handle objects from about fist sized to the size of a human being.

Arrangements to use the 3D Scanners can be made by filling out the Innovation Lab Consultation Form. Due to the difficulty of using these scanners, they are limited to academic projects only.
