3D Printing With Fungus

ThreeDPrinting (3752109) writes "One of the more intriguing ways that 3D printing is being used to create art has been developed by a Dutch artist named Eric Klarenbeek. He has gone beyond using the standard heated plastic or powdered metal to create 3D printed objects. He has found a way to use fungus to create objects like chairs that are not only durable, but also compostable.

The way it works is that Klarenbeek grinds up straw and mixes it with Mycelium fungus. The result is a filament that can be used just like any other material in a FDM printing, but with a twist. Unlike plastic or metal, the combination straw/fungus material does not need to be heated as it is used in the additive manufacturing process.

Once the object is printed, Klarenbeek soaks it with water and sets it aside. The fungus grows, replacing the water, and creates an object that is much like cork.

The next step is to create an outer shell using bioplastic and then placing the straw/fungus object in it. The Mycelium continues to grow and, in a couple of days, creates a structurally sturdy object.

Klarenbeek claims that this 3d printing technique can be used to 3D print just about any object, from small figurines, to furniture such as tables and chairs, to eve an entire house. The results are literally manufactured products made with a living organism.

A house made of what is essentially the same stuff that mushrooms are made of would be a fascinating thing to see. In any case Klarenbeek may have found a way to create products for people who are both technologically savvy and environmentally sensitive."

3D Printing Opportunities using epoxy resins

ThreeDPrinting (3752109) writes "One of the fascinating aspects of the emerging technology of 3D printing is how researchers are experimenting with different materials. Thermoplastics and powdered metal are already standard materials for the additive manufacturing process. Gizmag reports that researchers at Harvard are delving into the 3D printing opportunities inherent in using an epoxy resin.

It is a truism in materials science that he stronger a material is, the denser and therefore heavier it tends to be. Conversely lighter materials tend to be weaker. The idea is to find or create materials that are at once strong and lightweight.

Balsa wood is one such material. It tends to be light and, because of a unique cellular structure, strong. It is used for such things as the blades of wind turbines as well as model cars and planes. The problem is that most balsa wood comes from Ecuador.

The Harvard researchers have found a way to create an epoxy resin material that can be used in a 3D printer that has a cellular structure that makes it better than balsa wood. They built the new composite using an epoxy-based resin containing nano clay platelets to increase viscosity, as well as two types of fillers – silicon carbide "whiskers" and discrete carbon fibers. What’s more, the researchers can play with the density of the material, controlling it as it gets spun out of the 3D printer.

The resulting structures are much stiffer and stronger than the standard thermoplastics currently used in 3D printing. This opens the way to building lightweight but stronger products from the wind turbine blades to lighter but safer cars that increase gas mileage."

Metamason: Revolutionizing CPAP masks with 3D Scanning and 3D Printing

Leslie Oliver Karpas (3764545) writes "As millions of Americans with Obstructive Sleep Apnea struggle to get a good night’s sleep, one company has harnessed 3D technology to revolutionize CPAP therapy. As the go-to resource for 3D printing news 3ders.org reported today, “Metamason is working on custom CPAP masks for sleep apnea patients via 3D scanning, smart geometry, and 3D printing.”

“We’re at the crossroads of 3D technology and personalized medicine,” says Metamason founder and CEO Leslie Oliver Karpas. “There are many medical products that would be infinitely more comfortable and effective with a customized fit. CPAP therapy is the perfect example—it’s a very effective treatment with a 50% quit rate, because mass-produced masks are uncomfortable and don’t fit properly.” CPAP is a respiratory device worn during sleep to treat OSA, which affects 1 in 4 men and 1 in 9 women in the US alone.

“Our design also gets rid of the undignified front-facing elephant tube most CPAP masks have, and redirects airflow around to the crown of the head, where it won’t interfere with your or your partner’s sleep,” explains Karpas.

Metamason’s “ScanFitPrint” process for creating their custom Respere masks translates a 3D scan of the patient’s face into a 3D printed custom mask that is a perfect individual fit. To print the masks in soft, biocompatible silicone, Metamason invented a proprietary 3D printing process called Investment Molding, which creates wholly integrated products that were previously considered “unmoldable.”

“3D technology is changing how products are made,” Karpas states. “We are thrilled to be at the front lines as changemakers, ushering in customization though parametric design and on-demand 3D manufacturing.”"

How 3D Printing Technology Will Affect Package Delivery by the Postal Service

ThreeDPrinting (3752109) writes | 41 minutes ago

ThreeDPrinting (3752109) writes "According to a recent report, the United States Postal Service may use 3D printing technology to revive its ailing business. The new technology would be a financial boon in a number of ways, but in the USPS’s traditional business of shipping packages and by having the government own mail service branch out into 3D printing items itself. The idea is that 3D printing will lead to more single item parcels being shipped over shorter distances rather than hundreds of thousands of identical items being shipped over longer distances. This will lead to less fuel consumption and less emissions. The USPS maintains a massive “first mile” and “last mile” delivery network that fits perfectly into a model in which businesses make 3D printed items close to their customers. As the technology matures and more people begin making 3D printed items at home, they will still need a way for materials like powders and binding materials. The USPS believes that its delivery network and its expertise in shipping lightweight packages will fit perfectly to satisfy this need. The postal service could go even further by partnering with businesses to actually install 3D printers on site at its various post offices along with micro warehousing. This would cut costs for the 3D printing manufacturer and would open up a new revenue stream for the USPS. To maintain the security of files which may have copyrighted designs, the postal service could provide its own network or even deliver the designs on physical media, providing a level of security that the Internet cannot meet. It short the postal service is thinking about how 3D printing could benefit its business and is planning to react accordingly."

Ask Slashdot: Getting bombarded by third party recruiters -- is this a scam?

bpm007dog (1260560) writes "Getting bombarded by third-party recruiters — is this a scam?

Problem #1: These parties are three levels from the primary — meaning the job-contracts are diluted by three layers, each layer getting their cut. Problem #2: 90% of these third-party firms (IMHO) english is their second language.

Million dollar question: How do your bypass these guys and talk directly to the primary?"

Precisely what makes a comment valuable to the FCC?

Presto Vivace (882157) writes | about an hour ago

Presto Vivace (882157) writes "1 Million Net Neutrality Comments Filed, But Will They Matter?

A record-setting number of Americans weighed in with their thoughts on this matter. But there's one problem, according to George Washington University law professor Richard Pierce.

"The vast majority of the comments are utterly worthless," Pierce says.

Oh really? and precisely what makes a comment valuable?

The folks who do comment with the detail, data and analysis that can change minds? Deep-pocketed industries.

"Those comments that have some potential to influence are the very lengthy, very well-tailored comments that include a lot of discussion of legal issues, a lot of discussion of policy issues, lots of data, lots of analysis," Pierce says. "Those are submitted exclusively by firms that have a large amount of money at stake in the rule-making and the lawyers and trade associations that are represented by those firms."

The FCC's Gigi Sohn also cautions against using the high number of comments in this matter as a tea leaf, because of the unknown content in the comments.

"A lot of these comments are one paragraph, two paragraphs, they don't have much substance beyond, 'we want strong net neutrality, ' " she says.

It would appear that Gigi Sohn and GW law professor Richard Pierce are unclear as to who the FCC works for. The FCC works for the American people, if we want something, that should be sufficient reason to rule in our favor."

Social Security spent $300M on "IT boondoggle"

alphadogg (971356) writes "ix years ago the Social Security Administration embarked on an aggressive plan to replace outdated computer systems overwhelmed by a growing flood of disability claims. Nearly $300 million later, the new system is nowhere near ready and agency officials are struggling to salvage a project racked by delays and mismanagement, according to an internal report commissioned by the agency. In 2008, Social Security said the project was about two to three years from completion. Five years later, it was still two to three years from being done, according to the report by McKinsey and Co., a management consulting firm. Today, with the project still in the testing phase, the agency can't say when it will be completed or how much it will cost."

How a solar storm two years ago nearly caused a catastrophe on Earth

schwit1 (797399) writes | 1 hour ago

schwit1 (797399) writes "On July 23, 2012, the sun unleashed two massive clouds of plasma that barely missed a catastrophic encounter with the Earth’s atmosphere. These plasma clouds, known as coronal mass ejections (CMEs), comprised a solar storm thought to be the most powerful in at least 150 years.

“If it had hit, we would still be picking up the pieces,” physicist Daniel Baker of the University of Colorado tells NASA. Fortunately, the blast site of the CMEs was not directed at Earth. Had this event occurred a week earlier when the point of eruption was Earth-facing, a potentially disastrous outcome would have unfolded.

Analysts believe that a direct hit could cause widespread power blackouts, disabling everything that plugs into a wall socket. Most people wouldn’t even be able to flush their toilet because urban water supplies largely rely on electric pumps. . . .

According to a study by the National Academy of Sciences, the total economic impact could exceed $2 trillion or 20 times greater than the costs of a Hurricane Katrina. Multi-ton transformers damaged by such a storm might take years to repair.

CWG’s Steve Tracton put it this way in his frightening overview of the risks of a severe solar storm: “The consequences could be devastating for commerce, transportation, agriculture and food stocks, fuel and water supplies, human health and medical facilities, national security, and daily life in general.”"

concertina226 (2447056) writes "Can people still have contact with their loved ones beyond the grave? Gamers on the internet are tearing up right now over a YouTube user's supernatural tale of rediscovering his father's spirit in an old Xbox game a decade after he passed away.

One of the users responding to the YouTube video was user 00WARTHERAPY00, who commented that after his dad died when he was six years old, he had been unable to touch the Xbox console that his father had played games with him on.

However, recently he discovered that the RalliSport Challenge game had saved his dad's winning lap and would replay the video of that lap over and over again, even though it was a decade since the record was set."

An anonymous reader writes "A central Iowa Boy Scout troop just returned from a three-week trip they will likely never forget.
Boy Scout Troop 111 Leader Jim Fox spelled out what happened to him and the Mid-Iowa Boy Scout Troop 111 as four van-loads of Scouts and adult volunteers tried to drive from Canada into Alaska.
Fox said one of the Scouts took a picture of a border official, which spurred agents to detain everyone in that van and search them and their belongings.
âoeThe agent immediately confiscated his camera, informed him he would be arrested, fined possibly $10,000 and 10 years in prison,â Fox said.
Another of the Scouts was taking luggage from the top of a van to be searched when something startling happened.
âoeHe hears a snap of a holster, turns around, and hereâ(TM)s this agent, both hands on a loaded pistol, pointing at the young manâ(TM)s head,â Fox explained."

Bitcoins.com domain auction cancelled after judge’s restraining order->
Submitted by Anonymous Coward on Thursday July 24, 2014 @10:32AM
An anonymous reader writes
"Heritage Auctions, the Texas company orchestrating the Bitcoins.com sale, pulled the auction listing on Wednesday afternoon, stating: "This lot has been withdrawn from this auction. Bids are no longer accepted and previous bids are cancelled."

The move comes as the result of a federal judicial order issued on Tuesday that put an immediate halt to the sale of Bitcoins.com, the domain name owned by embattled Mt. Gox CEO Mark Karpeles.

"The lot is being held for now so we can get this sorted out one way or the other," Noah Fleisher, a Heritage Auctions spokesman, told Ars. "I haven't heard from [Karpeles] at all."

An anonymous “company executive” (presumably Karpeles himself) told The Wall Street Journal in May 2014 that Mt. Gox's parent company Tibanne hopes to raise around $1 million by selling bitcoins.com and the Bitcoin trademarks it holds in the European Union and Japan because the company has “no use for them.”

The temporary restraining order, which was issued on Tuesday by a federal judge in Washington, comes as part of an ongoing lawsuit between CoinLab and Mt. Gox KK and its parent company, Tibanne. The order forbids the two Japanese companies from selling or otherwise transferring any assets for 14 days.""

3D archaeology - now low-cost, high-volume and crowd-sourced

Anonymous Coward writes | 3 hours ago

0

An anonymous reader writes ""Archaeologists have long had a taste for computer-based methods, not least because of their need to organise large datasets of sites and finds, search for statistical patterns and map out the results geographically. Digital technologies have been important in fieldwork for at least two decades and increasingly important for sharing archaeology with a wider public online. However, the last decade of advances in computer vision now means that the future of archaeological recording – from whole landscapes of past human activity to archaeological sites to museum objects – is increasingly digital, 3D and citizen-led...""
