US Navy, Texas A&M team up to advance 3d-printed steel technology


Material researchers from the United States Navy and Texas A&M University have developed a way to create 3d-printed steel that matches the tensile strength capabilities of traditional steel manufacturing. 

The approach relies on a mathematical model to, as Engineering.com reports, “optimize laser settings to drastically reduce the type of printing flaws that reduce tensile strength.” 

When compared with conventional casting and subtractive steel manufacture, 3d-printing fabrication typically results in a higher number of microscopic gaps within the material that result from the 3d-printers additive making process. Those who have used a desktop 3d-printer will know that by definition, the printer deposits each successive layer one on top of the other, often leaving imperfections at the edges and never quite matching exactly the intended form. That phenomena is paralleled within the material itself, producing a 3d-printed object that is also filled with tiny air gaps and other materia...

Geo-Matrix Towers Span Across Oceans To Connect The Planet

Resim
Editors’ Choice 2020 Skyscraper Competition Ruwan Fernando Australia Ever since the Apollo mission showed us the first images of our ‘pale blue dot’ from space, the idea of the world as a ‘whole’ has captured the people’s imagination. Going beyond borders, oceans, and thinking of the continents as a continuous entity comes from this vision. Fifty years later, we face the existential threat of ecological disaster, and maybe revisiting the whole earth project seems like a way of recapturing that drive. This proposal looks at a network of towers that span across the oceans connecting the planet in a matrix that provides energy cleans the oceans and gives new chances for life to thrive. Fusion, Solar, and Hydro-power are used in this matrix with all of these being in high abundance in the ocean. The towers are also self-sufficient and mine minerals from the water as well as farm to support their communities. Research and manufacturing also feature heavily. The connections of the g

Wood Urbanism

Wood Urbanism: From the Molecular to the Territorial Daniel Ibañez, Jane Hutton, Kiel Moe (Editors) Actar Publishers , November 2019 Hardcover | 8 x 10-1/4 inches | 488 pages | English | ISBN: 978-1945150814 | $54.95 PUBLISHER'S DESCRIPTION : Wood holds unique and timely lessons for urbanization, yet it remains inadequately characterized in architecture, landscape architecture, and urbanism. From under-considered thermal properties to emerging manufacturing possibilities, from changing forestry regimes to larger carbon cycle dynamics, Wood Urbanism explores the unique material and scalar properties of wood, presenting it as a critical material for design today. It brings into conversation scholars and practitioners who focus on wood from a range of perspectives: from the working forest to the mid-rise building to the basic cell. Drawing from the inherent intelligence and depth of multiple disciplines, this book offers a transcalar perspective on the role of wood in cont
