  Tvasta , a Chennai-based deep-tech startup incubated at Indian Institute of Technology, Madras, has made history by constructing India’s first 3D-printed villa for Godrej Properties in Pune. This ground-breaking achievement in modern construction uses 3D printing technology to create intricate, futuristic designs with reduced construction time. The innovative 3D printing process not only ensures faster build times but also reduces material waste, making it an eco-friendly choice. The villa features superior insulation, leading to lower energy consumption. Tvasta’s revolutionary approach is setting new standards in the construction industry, and this project marks a step forward in sustainable and customized housing solutions. source: thekarostartup.com #3dprinting

The United States Patent and Trademark Office recently issued patent 12,178,937 entitled “Compositions and Methods for Adhesion to Surfaces,” which constitutes the 10th U.S. patent that covers the TETRANITE bone adhesive technology. This patent expands the protected technology to include injectable mineral-organic structural bone adhesive compositions that comprise alpha tricalcium phosphate. The issuance of this patent complements RevBio’s existing U.S. patent 11,638,777, which covers the method of repairing fractured bone using the aforementioned adhesive composition. These recently issued patents enlarge RevBio’s portfolio of adhesive compositions for bone repair. The novel TETRANITE biomaterial is also the only patented bone adhesive to include phosphoserine, an organic compound, which has been shown in published literature to play a role in the process of bone regeneration. "The granting of this patent continues to expand RevBio's controlling intellectual proper...

  Today's KNOWLEDGE Share  Why do thick parts need more packing than thin ones ? Packing changes the parts size/volume/mass, but not the final density. Whatever is already solid at the end of fill (frozen skin) does not need any packing (shrinkage has already occurred !). So, as the picture shows (in a slightly exaggerated way) in a thin part/section one only has to pack a tiny fraction of the total volume, whereas in a thick part/section, most of the volume will need to be packed, to compensate for the shrinkage. Since thick parts are easy to fill and need more packing, it is not unusual to use a packing pressure much higher than the filling pressure. Something that might not fit the default values proposed by simulation... Always think twice before accepting a default value. credits:Vito leo

  Today's KNOWLEDGE Share A team of researchers from Waseda University, led by professor Chiharu Tokoro from the Department of Creative Science and Engineering, have come up with a novel direct discharge electrical pulse method for efficiently recycling CFRPs. Direct Discharge Electrical Pulse Enhances Carbon Fiber Recycling: Carbon fiber-reinforced polymers (CFRPs) are used in the aerospace, automotive, and sports equipment industries. However, their recycling remains a major problem. In a recent study, researchers demonstrated a novel direct discharge electrical pulse method for the efficient, effective, and environmentally friendly separation of CFRPs to recover high-quality carbon fibers. Recycling CFRPs presents a significant challenge, with waste management being a pressing issue. Conventional recycling methods require high temperature heating or chemical treatments, which result in high environmental impact and elevated costs. It has been a challenge to recover high-quality ...

Today's KNOWLEDGE Share Lapo Srl, a global leader in eyewear lenses manufacturing, and Trinseo, a specialty and sustainable material provider, today announced their collaboration to develop demonstration lenses made of recycled polymethyl methacrylate (PMMA) resins with a minimum of 86% recycled content.  “As a lens manufacturer for high-end eyewear, we are joining the sustainability journey with our customers and end-users,” said Luigi De Donà, owner of Lapo. “This inspiring partnership with Trinseo paves the way for more sustainable solutions to come to life. “We are honored to partner with Lapo and encouraged to see more of our recycled materials becoming part of daily life,” said Aldo Zanetti, Global Sustainability Business Development Leader for Engineered Materials at Trinseo. Typical material for lenses PMMA, also known as acrylic, is typically used for making lenses due to its high transparency for optical performance, lightweight and hardness. PMMA is the polymer obtained ...

  Today's KNOWLEDGE Share PS200 is our revolutionary 98% bio-based resin system derived from a low-carbon source – bagasse, a by-product of sugar cane processing. Highly flame retardant, PS200 offers thermal and fire protection with continuous service possible up to 150-200°C (dry), depending on the application. Having a unique ability to cope with high pressures and rapid temperature excursions >500-1000°C, which are typical of a Lithium-ion battery thermal runaway, PS200 meets fire protection and insulation standards ISO 2685 and AC 20-135, Revised 1990. Ideal for manufacturing battery boxes, PS200 has many other applications with high abuse temperatures including brake ducts and engine covers. We are committed to working with the composites supply chain in our combined efforts to achieve Net Zero by 2050. To achieve that, we must accurately quantify and minimise the emissions embodied in our products as well as emissions created by the company as a whole. We have partnered wi...

Avantium N.V., a leading company in renewable and circular polymer materials, has signed a joint development agreement with Amcor Rigid Packaging USA, LLC a leader in responsible packaging solutions. This partnership aims to explore the use of Avantium's plant-based polymer PEF - branded as releaf® in rigid containers for various products, including food, beverage, pharmaceutical, medical, home, and personal care. Additionally, Amcor has committed to a multi-year capacity reservation for PEF from a future industrial-scale facility, based on a technology license from Avantium. This agreement guarantees Amcor preferred access to PEF volumes produced by Avantium's future licensee network. Avantium has developed a proprietary process technology to produce FDCA (furandicarboxylic acid), the key building block for PEF (polyethylene furanoate), and is currently in the process of starting up the world’s first commercial FDCA plant in Delfzijl, the Netherlands. This FDCA Flagship Plant ...
