DXC Technology has patented a method for creating 3D printing material from aluminosilicate powder derived from igneous anorthosite rock. The process involves heating the powder to form molten material, extruding it through a nozzle, and cooling to create hardened material without the need for additives.
Method for preparing 3d printing material from aluminosilicate powder
A recently granted patent (Publication Number: US11858852B2) discloses a method for preparing a three-dimensional printing material using igneous anorthosite rock, predominantly plagioclase feldspar, ground into aluminosilicate powder. The process involves heating the powder to a temperature between 1,100°C and 1,750°C, maintaining it at this temperature to form molten material, extruding it through a nozzle to create a bead, and then cooling it at a specific rate to harden the material. The resulting hardened aluminosilicate material exhibits specific characteristics, including a compressive strength of about 20,222 psi and specific mineral compositions like albite/anorthosite feldspar and calcite.
Furthermore, the patent also details a method for constructing a building structure using the same aluminosilicate material prepared from igneous anorthosite rock. This method involves extruding the molten material through a nozzle onto a foundation or previous layer, cooling it to form a hardened material, and then stacking additional beads vertically to build the structure. The resulting hardened aluminosilicate material has a porosity of 14-15% and contains between 50% and 90% feldspar. The process is facilitated by a system including a hopper, tubular member, auger, and electric reactor assembly mounted on a robotic motion platform, showcasing a comprehensive approach to utilizing the unique properties of igneous anorthosite rock for construction purposes.
