Materials for Construction 3D Printing
3D printing is an art form that for designers, architects and hobbyists to create art and functional objects. There are the designers who create unique artistic forms which could not be created by any other means, by printing in clay, ceramics and composite materials.
Cob – a composite material, a mixture of clay, sand, straw and water, worked by hand from the ground monolithic walls. processed without formwork, no cement, no compression, no machines.
Adobe – earth bricks dried in the sun.
For reinforcing the 3D poured walls, instead of steel rebar, we will use fiberglass rebar which has superior tensile properties, built-in corrosion resistance and inherent electromagnetic neutrality, as follows:
– Corrosion Resistance, will not rust and is rezistent to the action of salt ions, chemicals, and the alkalinity inherent in concrete.
– Lightweight: weighs approximately one-quarter the weight of an equivalent size steel bar, offering significant savings in both placement and use.
– Electromagnetic Neutrality: contains no metal, does not conduct magnetic fields and will not interfere with the operation of sensitive electronic devices.
– Thermal Insulator: highly efficient in resisting heat transfer, such as from building exteriors to interiors; will not conduct electricity.
Combining recycled materials and quick-dry cement, the Builder’s 3D Printer squeezes out layer upon layer of pasty materials in strong diagonal shapes, which then harden. The pieces are reinforced with fiberglass, and then filled with recycled cellulose fiber insulation, like any other wall when building an eco house.
