[Words appear: Indiana University presents]
[Video: Indiana University's Jon Racek is helping build a playground at a school in Rwanda.]
[Video: Close-up of hands holding pieces of colorful wood, as a person is using a hammer to nail them together.]
[Video: Racek watches and advises an Indiana University student on how to use a saw to cut a tire that will be used as part of a children's playground in Rwanda.]
[Video: Close-up of 3D-printed objects and tools used to assemble these objects.]
[Video: Jon Racek, a senior lecturer in comprehensive design at the School of Art, Architecture + Design, appears on camera.]
Racek speaks: What we're trying to do is fill a void here in Rwanda. You can easily buy lots of basic items. But things that are more specialized, that are a little bit more complex are harder to find. Sometimes you can get them in other countries, but shipping is an issue, and expense is an issue.
[Video: Racek is carrying a 3D printer. He's walking in to a high school in Rwanda with the machine.]
[Video: Racek shows a group of Rwandan teachers and an Indiana University doctoral student how to use the 3D printer. They watch him intently.]
[Video: Close-up of a corn sheller tool that is designed to remove corn from a cob quickly. A man's hands are shown as he uses the sheller. A Rwandan teacher smiles while he uses the corn sheller. Corn falls from a cob onto a table as it is being shelled.]
[Video: Racek and his student are sitting at a table in a laboratory at Indiana University Bloomington, using tools to assemble prosthetic hands.]
[Video: Close-ups of Racek's and the student's hands can be seen as they are using these tools to build the prosthetic hands.]
[Video: Close-up of a 3D printer in use at the Indiana University Bloomington laboratory.]
[Video: Racek shows a group of Rwandan teachers and an Indiana University doctoral student how to use the 3D printer. They watch him intently.]
[Video: Racek appears on camera.]
Racek speaks: So what we're trying to do with the 3D printer is set up a lab, whereas the school and the community are able to print certain objects that might be helpful. So, for instance, we have a corn sheller, which was designed by a student at MIT, and that allows people to take the corn off the cob. Now they do it by hand, and it takes about 15 minutes per cob to get the corn off. And with this corn sheller, it's a rotating motion, and the corn just falls right off. It takes about 30 seconds, so we're saving people a lot of time. Initially, we're making objects that they can choose from. But in the future, we will be working closely with my students at IU, and the community here will describe the specific local problems that they have. My students will design and prototype using a 3D printer back in the U.S. and when they have something that works, they will email that file to the 3D printer here in Rwanda, and then the community members can do some more prototyping and see if we get it right.

[Video: The Rwandan teachers study pieces of the 3D printer and learn how to operate the machine.]
[Video: Racek, the Indiana University doctoral student and the Rwandan teacher, smile and wave for a group photo.]
Racek speaks: The teachers were really excited about the possibility. What got me really excited is the fact that they understood what we were trying to do. They may not understand all parts of the technology yet -- they'll get there -- but what's important is that they understand the big picture, and how these different tools that we're going to be printing can actually help people.
