The walls of this $130,000 3D printed home were built in 18 hours — see what it's like inside

• Startup Havelar built Portugal's first 3D printed home using COBOD's popular printing system.
• The walls of the two-bedroom, 861-square-foot home were printed in 18 hours.
• The Portugal-based startup says it can build faster and cheaper than conventional construction.

If companies like Portugal-based Havelar have their way, the future of affordable housing will look like perfectly stacked strands of spaghetti (as in, they'd be 3D printed).
