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.
