3D Printing and ABS Recycling: Assessing Virgin and Re-used Filament

In the recently published ‘Investigation of closed loop manufacturing with Acrylonitrile Butadiene Styrene (ABS) over multiple generations using Additive Manufacturing,’ authors Mazher Iqbal Mohammed, Daniel Wilson, Eli Gomez-Kervin, Bin Tang, and Jinfeng Wang explore the impacts of FFF 3D printing on acrylonitrile butadiene styrene (ABS) during multiple recycling processes. As 3D printing increases in popularity, so does the amount of discarded plastic. And while PLA is biodegradable, ABS is a typical plastic that is not—presenting environmental issues. In this study, the researchers hoped to explore FFF systems in regard to their low power consumption which may lend themselves to a path of greater manufacturing sustainability. The researchers began using virgin ABS, put through two successive closed-loop filament extrusion and 3D printing phases. In this study they used 100 percent recycled 3D printed ABS, made into filament for re-use—allowing them to investigate parameters and potential for defects along the way. “Studies have previously reported that changes in melt flow index and mechanical properties occur with ABS after recycling using injection and cast-molding,” state...

Squabble takes violent turn: One Asif Yusuf Shaikh bites off finger of victim, keeps abusing him even after spitting out severed finger

The victim, Mahesh Pandurang Dhumbre, who works for an insurance firm and lives in Ghansoli, went through a corrective surgery on Friday evening. A squabble over a standing spot near the door in Asangaon fast train took a violent turn as one of the individuals involved in the quarrel named Asif Yusuf Shaikh suddenly chewed off a part of the index finger of the other co-passenger. The incident took place on Thursday evening in Mumbai on a peak-time Asangaon fast local and the accused was arrested at Thane station by GRP after fellow commuters cautioned the police. The victim, Mahesh Pandurang Dhumbre, who works for an insurance firm and lives in Ghansoli, went through a corrective surgery on Friday evening. On Thursday, after finishing off his work, he went on board the first-class compartment of the 5:40 PM local train at Dadar. The accused, Asif Yusuf Shaikh, hopped on the train from Kurla station and jostled Dhumbre and other passengers standing near the door. “He was trying to push others in order to make space for himself but the local was jam-packed and there was scarcely any space. In his struggle to carve a space for himself, he precluded others from boarding the train. S...

Blinky LED projects: we just can’t get enough of them. But anyone who’s stared a WS2812

Blinky LED projects: we just can’t get enough of them. But anyone who’s stared a WS2812 straight in the face knows that the secret sauce that takes a good LED project and makes it great is the diffuser. Without a diffuser, colors don’t blend and LEDs are just tiny, blinding points of light. The ideal diffuser scrambles the photons around and spreads them out between LED and your eye, so that you can’t tell exactly where they originated. We’re going to try to pay the diffuser its due, and hopefully you’ll get some inspiration for your next project from scrolling through what we found. But this is an “Ask Hacakday”, so here’s the question up front: what awesome LED diffusion tricks are we missing, what’s your favorite, and why? Look closely enough at an RGB LED and you’ll see three individual LED chips, not surprisingly in red, green, and blue. We all know this, and yet it’s still surprising how badly blended the colors can be, even from an LED unit like the WS2812, where the three diodes are ridiculously tiny and less than a millimeter apart. Somehow, even at desk-distance, you still get the feeling that you’re looking at a red LED and a blue LED instead of a blended magenta ligh...

Protected agriculture reaches 126,000 acres in Mexico

Protected agriculture is coming on like gangbusters in Mexico. As of 2018, there were about 126,000 acres of protected agriculture in that country. That’s a big jump from the 325 acres planted in 2003. Greenhouse production accounted for 27%, shade houses made up 45%, and macro tunnels, used primarily for berries and anti-hail meshes for apples, equaled 29%, according to AMHPAC – the Mexican Association of Protected Horticulture. About 78% of the vegetables grown under protected agriculture are destined for the U.S., with 5% exported to Canada. Tomatoes accounted for about 55% of the vegetables, and cucumbers and bell peppers each made up about 20%. Although protected agriculture was only 2% of Mexico’s fruit and vegetable acreage and tonnage in 2018, it accounted for 17% of the dollar (or peso) valuation, according to the office of Mexico’s secretary of agriculture. Protected agriculture has proved so successful that some U.S. distributors source 100% of certain commodities from greenhouses.  For example, all of the cucumbers, bell peppers and round and roma tomatoes distributed by Ciruli Bros. LLC, Rio Rico, Ariz., are grown in greenhouses, said partner Chris Ciruli. Greenhous...

A Water Purifier May Be the Only Savior against Water Pollution

Water is the driving force in all of nature. It is the basic need for a human being or any animal to survive. You can stay without food for many days but just a few hours without water and you will feel extremely restless. A cool glass of water at such times is like a precious gift; more valuable than the riches of the world. It is essential for your survival and with that for your overall health. Purified water is often considered a magic ingredient and is packed with medicinal properties. But why is there a stress on purified water? If you look around you, water pollution is everywhere. You will not find one river in India that is clean and safe. Even the holy Ganges stinks of garbage. The once holy water of the Ganges, Yamuna and many such holy rivers are full of microbes, bacteria and pesticides and can cause extreme health related problems to everyone. The most common cause of water pollution in India is untreated sewage that is disposed in the rivers. Other major causes include disposal of plastic waste in the rivers, disposal of industrial waste and let’s not forget how everyone of us throw anything and everything in the water bodies! The situation is getting worse day by...
