  • Composition and production method for 3D printing construction material
    Patent number: 12037500
    Abstract: A composition for a 3D printing construction material includes an acrylate oligomer, an acrylate monomer, a UV photoinitiator, a flame retardant, fillers, and additives. In the composition, the acrylate oligomer may be between about 0-30.0 wt % of the composition. The acrylate monomer may be between about 0-30.0 wt % of the composition. The UV photoinitiator may be between about 0.02-1.0 wt % of the composition. The flame retardant may be between about 2.0-20.0 wt % of the composition. The fillers may be between about 20.0-80.0 wt % of the composition. The additives may be between about 0-3.0 wt % of the composition. A method for manufacturing a composition for a 3D printing construction material includes combining an acrylate oligomer, an acrylate monomer, an Uaphotoinitiator, a flame retardant, fillers, and additives.

  • COMPOSITION AND PRODUCTION METHOD FOR 3D PRINTING CONSTRUCTION MATERIAL
    Publication number: 20230331890
    Abstract: A composition of 3D printable photocurable material can include acrylate monomer(s) between about 0-30.0 composition wt %; acrylate oligomer(s) between about 0-30.0 composition wt %; photoinitiator(s) between about 0.02-1.0 composition wt %; chopped fiber(s) between about 0.1-3.0 composition wt %; flame retardant(s) between about 2.0-20.0 composition wt %; processing aid(s) between about 0.05-3.0 composition wt %; additive(s) between about composition 0-3.0 wt %; and filler(s) between about 20.0-80.0 composition wt %. The composition can have a viscosity of about 10,000-300,000 mPa·s, can be configured to be extruded at a printing speed of about 7-90 cm3/s during 3D printing, can be photopolymerized under UV or visible irradiation at a material depth of about 4-8 mm, and can be cured to form a building construction material.
