Industrial Offices:
Yingchuang New Materials Inc. has developed a 3D printer capable of printing the structural system and walls for small buildings. Their completed project includes 10 single-room structures constructed to be used as offices in a Shanghi Industrial Park.
The 10 buildings were printed in under 24 hours, at a cost of approximately $5000 per building. The parts were printed and cured in a warehouse, then shipped to the site for assembly. The finishes, plumbing work, electrical work, and mechanical work had to be added after the structure was assembled at the site.
The process relies on a fused deposition modeling process to extrude the material in layers. This is the same process used by many consumer-grade 3D printers. Yingchaung's process relies on materials recycled from demolished buildings.

Residential:
The Canal House Project by Dus Architects seeks to replicate the hand-laid brick exterior of the traditional canal-style homes, with an updated twist. Their goal is to 3D print the entire building out of an extruded bio-plastic, working in sections to create a black textured facade that (arguably) fits its context on the site.
The project, located in Amsterdam, is projected to take 3 years and will form a 13-room structure at its completion. The individual pieces will be extruded in units, which will then be interlocked and stacked to form the final structure.
The same firm has used similar technologies to produce a translucent plastic useable for windows, and a saw-able wood fiber mix, similar to MDF.
