Porous structures fabricated through selective laser melting (SLM) are prospective candidates for high-energy-absorbing applications due to their tuneable mechanical properties. The Menger Fractal Cube (MFC) is a unique fractal cube formed through iterative removal of smaller cubes from a larger one. It is distinguished by its intricate self-similar pattern of voids and cubes repeating at diminishing scales, resulting in a lightweight and highly complex structure. Using AlSi7Mg, compression experiments and simulations investigated MFCs with three different orders. Digital image correlation was...

The United States Department of Agriculture Rural Development announced on Tuesday that it is investing $76.5 million to expand the Red Mesa Tapaha Solar Farm, according to a press release.

This paper presents the first-ever investigation of Menger fractal cubes' quasi-static compression and impact behaviour. Menger cubes with different void ratios were 3D printed using polylactic acid (PLA) with dimensions of 40 mm × 40 mm × 40 mm. Three different orders of Menger cubes with different void ratios were considered, namely M1 with a void ratio of 0.26, M2 with a void ratio of 0.45, and M3 with a void ratio of 0.60. Quasi-static Compression tests were conducted using a universal testing machine, while the drop hammer was used to observe the behaviour under impact loading. The...

Mondo is back with some impressive 1/6 scale figures from X-Men: The Animated Series including the arrival of Rogue 

Batman: Arkham Knight is a bit harder than the previous games, so you need to get the best upgrades quickly for a tactical advantage.
