Case In-Depth Analysis: MS1 3D Printed Ruggedized Tablet Casing for Industrial Use
A technology company required a lightweight yet impact-resistant tablet casing for field technicians. Using our carbon steel 3D printing service with Tool Steel MS1, we produced ruggedized casings achieving tensile strength above 1950 MPa and density over 99.5%. Advanced lattice-reinforced designs reduced weight by 20% compared to conventional cast aluminum casings, while withstanding drop tests from 2 meters onto concrete without deformation. Post-processing included HIP treatment and CNC machining for interface precision and final surface smoothing.
