Scientists create self-healing plastic, the ‘Holy Grail of Material Science’

Cell phones, tablets, cars and even weapons systems that can heal themselves when scratched or cracked are no longer confined to science fiction. During the American Chemistry Society’s annual conference on Monday, University of Southern Mississippi Professor Marek Urban demonstrated the new material and discussed numerous potential applications. When scratched or cracked, the new plastic responds on a molecular level and regenerates to repair itself without leaving any signs of damage. According to some scientists, the material is considered the “Holy Grail of Material Science.” Read on for more. More →

MakerBot’s Replicator is the personal 3D printer we’ve been waiting for

MakerBot’s Replicator is the personal 3D printer we’ve been waiting for

MakerBot announced their brand new personal 3D printer, the Replicator, at CES yesterday and we just had a chance to see it up close and in person. What do we think? Well, let’s just say that we want one of them, and fast. For starters, the unit comes preassembled from MakerBot, but it also features a larger printing footprint so you can print even bigger designs. There’s also the option of using two different colors of plastic to print two-color objects — you can also choose from either ABS plastic or a more eco-friendly variant. While the printing footprint is larger, the unit itself isn’t that big, and it’s reasonably quiet. In fact, it seems more quiet than the previous models MakerBot offered. It starts at $1,749.99 and goes up to $1,999.99 if you’d like the dual extrusion option. Check out our gallery to see the unit for yourself.
