A gigantic 3D printer built this 12,000-square-foot mansion layer by layer

Remember that Chinese construction company that uses a giant 3D printer to make prefab homes out of concrete? Well it’s moved beyond the measly little 650-square-footers it started with and has recently produced a hulking, 12,000-square-foot mansion.

Despite being drastically bigger than previous homes, WinSun Decoration Design Engineering Co. constructed the house with the same equipment it has used in previous builds: a gigantic, room-sized 3D printer.

Measuring in at roughly 105 feet long, 33 feet wide, and 21 feet tall, this hulking 3D printer works almost exactly like a normal one — just on a much larger scale. It pumps a special type of pre-mixed concrete through a nozzle and onto a flat substrate. Layer by layer, it prints out a number of building blocks, which are then transported to the construction zone and pieced together to create the structure.

Check out the slideshow above to see what it’s like.

Space heaters are a simple (and affordable way) to keep your home warm during the chilly winter months. Offered in a variety of sizes, you'll find models designed for small offices, sprawling living rooms, and everything in between. However, space heaters are also responsible for house fires and other accidents -- meaning you have to be careful with how you use them.

Before rushing out and adding a space heater to your home, here are a few things to consider. From checking available safety features and finding the right size to placing it in your home and avoiding smart plugs, here’s everything you need to know about these useful gadgets.
Check for crucial safety features
The most important feature to look for in a space heater is the tip-over switch. Products with a tip-over switch will automatically turn off when they're knocked over, making it an indispensable safety feature. It’s rare to find products without a tip-over switch nowadays, as all the best space heaters use them.  But if you're shopping for older devices, be sure it has one of these. If it doesn’t, the heater will pose a serious fire hazard if it gets knocked over.
