When you're done, simply download the design file generated by the app, upload it to the printer, and get printing. Step 2. Choose Your Materials The first 3D printers produced only plastic parts.

Makers will likely come across numerous STL files as they explore the various forums dedicated to the craft. They're frequently posted on print-sharing sites like Thingiverse and MyMiniFactory.

What is an STL file? In layman’s terms, an STL file contains 3D meshes, geometry, and other related information and is used for 3D printing, rapid prototyping, and computer-aided manufacturing.

Learn how to design and 3D print with Tinkercad in this beginner-friendly guide. Step-by-step tips to turn your ideas into tangible creations.

When you're done, click Design > Download for 3D Printing and you'll immediately get an STL file you can load into your printer.

What settings should I use? Most 3D printers include or link to recommended software, which can handle converting 3D STL or other files into formats supported by the printer.

The most common reason an STL file may be not quite right is a mechanical connection where some piece isn’t quite as the designer expected, so the 3D model that interfaces with it no longer fits.

Homo naledi fossil scans are now available to 3D print at home. But what other hominin fossils can you download for your collection?
