Lincoln Diuguid, an African American who was born as the brutality of slavery was rapidly being replaced by the yoke of Jim Crow, was warned that it was fruitless to pursue his dream of becoming a scientist.

The discouraging words had the opposite effect on him.

Most people have heard of 3D printing, but few have ever seen these printers up close and in action.

Scott Rocca, co-owner of Griffin 3D, a St. Louis start-up, is trying to change this by showcasing his company’s printers at numerous events, such as the Science Center’s First Fridays. People can come and watch the printers. Soon they will be able to buy their own.
