3D Printable Cement for 3D Printing Houses and Structures
While 3D printing homes still sounds like something that only happens in science fiction, the technology is coming along nicely. There are naturally a few hurdles to overcome before it becomes commonplace, but most of the pieces are already in place.
Companies have developed large robots capable of acting as large-scale 3D printers, and new concrete and cement formulas are being developed regularly. The major obstacles at this point seem to be the cost of the procedure, which is bound to drop as the tech becomes more common, and the versatility of the robot doing the 3D printing. However, those are relatively minor technological obstacles that don’t seem to be slowing down the advancement of the process.
The real obstacles are, as always, materials. The concrete and cement materials need to be well suited to constructing with large-scale 3D printing robots, and they need to be able to dry quickly to support themselves and bond together firmly. Thai cement maker Siam Cement Group (SCG) has developed an amazing new cement that is mixed with a special combination of powder materials and fibers that allow it to quickly be printed into non-traditional shapes. It binds quickly enough that it can be printed with dramatic curves and twists, and it can remain freestanding while drying without the need for support material.
