The paper presents an alternative binder for structural 3D-printing with composite materials. The binder eases the control of setting times after extrusion through thermoplastic hardening properties. The material could therefore enable the production of thin-walled geometries in large-scale 3D-printing with higher degrees of freedom in respect to overhanging geometries without supporting structures. The proposed composite material is made from mineral aggregates and biological gels, resourced from animal tissue and bone. The used mineral aggregates are not deviating significantly from conventional concrete or
mortar.
So far, the research determined a maximum flexural- and compressive strength of 8 MPa and 21 MPa. Furthermore, first material compositions are introduced and respective material properties tested. As a conclusion, the paper presents limitations and potentials of the concrete for the use as structural building material and the use within large-scale 3D-printing.
