The onslaught of 3D printers has created a booming market for machines that can make quality products at home. Glowforge is a new object-maker that's a 3D laser printer, cutter and engraver rolled into one. It will help DIY enthusiasts churn out a range of products with wood, acrylic, leather, fabric or even glass. The cutter uses a dual camera technology for realtime autofocus so it helps aligns the laser head with your pattern and makes the cutting process easy. The camera recognizes the material and even follows the beam of light, which is the width of a human hair, so it can adjust the timing and position every step of the way.
