3D Printed Sandwich Structural Decks of Dual Corrugate Sheet with Mid Shear Layer (DCMSL) as Core Profile

Rectangular sandwich decks in an exclusive profile that has an additional shear layer in the mid of its dual corrugate monolithic core , developed on 3D printing, has been highlighted here in this paper. These sandwich decks in construction mix material when 3D printed out having such a monolithic core profile, factually offers getting rid off invariably otherwise required any bonding to attach the two or more components of any sandwich panels. Having observed a consistency in various numerical results as obtained through analyses carried out using ‘Advanced Composite Technology(ACT) with that observed from various conducted load tests on these 3D printed hardware , sandwich deck units, are then favourably recommend for their effective deployment in any civil engineering application. A fruitful observation has been made here on a suitable orientation tht need only be maintained in this orthogonal dual corrugate sheets monolithic core profile sandwich for their excellence in performance for service as compare to that of any so far used single corrugate sheet core sandwich profile.
