Three Quick Takes On 3D Printing

#1 - If You Have a 3D Printer You Can Make Yourself a Cheap Robotic Lawn Mower

Andrew Liszewski | Apirl 13, 2016




A decent robot mower will set you back a couple thousand dollars, considerably more than the robot vacuum that’s patrolling your living room for dust. But if you’ve got access to a 3D printer and a bit of electronics know-how, you can print and build a robotic mower for a fraction of the cost.

Additive manufacturing (AM) is altering the way that most industries do business, but one field that could definitely stand to drop its production costs with 3D printing is that of the space industry.

Aerogels are among the world’s lightest materials. Graphene aerogel, a record holder in that category, is so light that a large block of it wouldn’t make a dent on a tiny ball of cotton. Water is about one thousand times more dense. The minimal density of aerogels allows for a number of possible applications, researchers have found, ranging from soaking up oil spills to “invisibility” cloaks.
