A METHOD FOR PRODUCING A COMPOSITION OF CONSTRUCTION MATERIAL FOR 3D PRINTING

摘要

Systems, devices, and methods are provided for producing a 3d-printable composite material for large scale printing. A method can include receiving a first component comprising a (meth)acrylic monomer or a (meth)acrylic oligomer, or a combination thereof. The method can include receiving a second component comprising a photoinitiator and a third component comprising a polymerization enhancer. The method can include mixing the first component, second component, and third component with a mixing reactor to form a mixture. The method can include filtering the mixture with a filtration unit and removing a solid residue from the mixture. The method can include curing the filtered mixture with a radiation unit into a gel component and a liquid component. The method can include separating the gel component with a phase separation unit and then milling the gel component. And the method can include mixing the gel component, the photoinitiator, the mineral filler and optionally the recycled previously printed composite material to form the composite material.
