First 3D Printed Carbon-Fiber Bike
a ‘Technological Marvel’

Thomas Industry Update, by Staff

Original Article

Posted By:Pete Stone, 6/13/2018 1:47:21 PM

According to Bicycling.com, the modern carbon-fiber bike is “a technological marvel” based on its superior strength over traditional metal bikes, at a fraction of the weight. So why isn’t everyone hopping on one of these top-notch bikes to pedal around town? Two reasons – the cost is insane and, say the experts at Bicycling.com, carbon-fiber can be a manufacturing nightmare. Typical problems mostly relate to quality control, in a production environment that requires lots of labor and precision, which is why the Silicon Valley startup Arevo intends to upend the process with 3D printing. The company has a

Comments:
Additive manufacturing (popularly called "3D printing") offers major advantages over more traditional technologies. Arevo seems to be making major advances in applying additive manufacturing to carbon fiber materials.

The 3D-printing idea sounds neat; but I still have lingering doubts about the durability of the bonds between individual layers. A load-bearing frame that is basically like carbon-fiber baklava doesn´t give me as much confidence as one where the material achieves its crystal structure bonding in an organically-three-dimensional manner, rather than laid down layer by layer (where each layer has time to set before the next layer gets laid down).

I suspect my doubts might be allayed if I learn more about the details of the process. Probably not until then, though...

The main advantage to 3D printing is the ability to build a bicycle for $80,000. I bet the cost comes down to under $10,000 within the time it took to make a useable electric car (a little over 100 years).

I do a tremendous amount of 3D printing making movie props. There is not a day that goes by my printers are not busily creating some new fanged thing I have drawn. It is really an incredible and yet very simple technology. What amazes me the most is how when things break around the house, I can quickly just print up a new one from a sketch. I have replaced all sorts of things, made our house numbers, made templates for neighbors painting kid´s rooms, custom name tags, jewelry, toys of all kinds, even a new, even stronger, better trigger for my weed whacker that my son broke (muscle man- he never knows his own strength). Everyone should have a 3D printer in the home- it should be as popular as a sewing machine or a pressure cooker. But, the hang-up is in the ability to draw what you want. However, that is also changing- I participate in a web site in which I draw things for other people as do thousands of talented creators. Most do it for free. Not to mention how many million items are already created digitally and are ready to download and print for no charge at all.

As for strength, the technology is so precise and the materials available so strong and versatile, from soft rubber for seals and gaskets to incredibly strong plastics, I can´t think of too many things 3D Printers can not make. This CF bike- should be a pretty amazing thing.

Dang, #3, you describe a truly brave new world.
3D printing as a household appliance seems to make a lot of sense. I hope I´m not too old to get up to speed on this. I can only assume cost, accessibility and available materials will skyrocket if it´s all you say.

Bitcoin is crashing. Here’s what

Bitcoin is now nearly a third of its record high of nearly $20,000 reached last December. To investors worried bitcoin´s bursting bubble could spill over into equities, one market watcher says the crisis is contained. "There are things to be concerned about in terms of the stock market here with emerging markets and other issues, but I don´t think bitcoin is going to be one of them," Matt Maley, equity strategist at Miller Tabak, told CNBC´s "Trading Nation" on Wednesday. Maley understands the fear, though. The steep rise and sharp fall in bitcoin prices is reminiscent of the 1990s dot-com

Trust in Self-Driving Cars is Wavering

A study conducted by AAA last month found that 73 percent of Americans don’t trust the current iteration of autonomous vehicle technology. That number is up from 63 percent as noted in late 2017. The study also found that: Only 20 percent of Americans said that they’d trust riding in a driverless vehicle. The largest decline in trust came from Millennials, with 64 percent saying that they wouldn’t ride in a driverless car. This compares with 49 percent who offered the same opinion in late 2017. Baby Boomers were still the most fearful of driverless cars, with 71 percent saying they

in North Korea talks

President Donald Trump recently confirmed that Secretary of State-designate Mike Pompeo secretly met with North Korean leader Kim Jong-un over Easter weekend, increasing the chances that Trump and Kim may have substantive talks when they meet. If the administration stays on track, it is possible the talks may significantly reduce the threat of war on the Korean peninsula, strengthen America´s overall national security, and achieve a diplomatic feat that none of the previous 12 presidents were able to realize. There is justification for cautious optimism: For the first time ever, the leaders of North and South Korea will meet

The deadly van attack in Toronto is shining a spotlight on the controversial, often misogynistic world of "incels." The term incel is short for "involuntarily celibate," and the community that uses the label is typically dominated by men voicing frustration online about their lack of sexual relationships, sometimes blaming women for their failures with the opposite sex. Toronto police said Tuesday that Alek Minassian, the 25-year-old suspected of driving the van that plowed into pedestrians on a busy stretch of Yonge Street in Toronto´s north end Monday, killing 10 people, is alleged to have published "a cryptic post on

The man arrested after allegedly plowing into pedestrians along a strip of one of Toronto´s busiest streets on Monday is expected to be charged with a 14th count of attempted murder in addition to the 10 counts of first-degree murder he already faces. Alek Minassian, 25, of Richmond Hill, Ont., was arrested after a white van left a trail of death and injury down a busy stretch of Yonge Street in north Toronto. At a news conference Tuesday, police said little about any possible motive Minassian may have had, but did refer to a "cryptic" message posted on his

Leftmedia Churn and the
Cost of Trump´s Affairs
Patriot Post, by Nate Jackson    Original Article

President Donald Trump is a man of low moral character. We know, “this just in.” Having led a very public life, nearly every American knows that Trump cheated on his first wife with his second and that he has generally been a philandering playboy. So in that sense it gets little more than a shrug when we hear that he had other affairs while married a third time. That was true of Stormy Daniels, and it’s true of Karen McDougal, who told CNN Thursday of her consensual 10-month affair with Trump from 2006 to 2007, before he was president.

If midterm elections were held today, five Senate Democrats would lose to Republicans, giving the GOP an even bigger edge in the chamber, according to new surveys from Axios/SurveyMonkey. According to the results, Democratic Sens. Jon Tester of Montana, Joe Manchin of West Virginia, and Joe Donnelly of Indiana are trailing generic Republican candidates. Sen. Claire McCaskill of Missouri trails the state´s Republican attorney general, Josh Hawley, in her re-election bid. Sen. Heidi Heitkamp of North Dakota will face Rep. Kevin Cramer, although Axios polled Heitkamp´s chances against a generic Republican candidate. As it stands now, Democrats have a better

Judicial Watch today released newly obtained internal IRS documents, including material revealing that Sen. John McCain’s former staff director and chief counsel on the Senate Homeland Security Permanent Subcommittee, Henry Kerner, urged top IRS officials, including then-director of exempt organizations Lois Lerner, to “audit so many that it becomes financially ruinous.” Kerner was appointed by President Trump as Special Counsel for the United States Office of Special Counsel. The explosive exchange was contained in notes taken by IRS employees at an April 30, 2013, meeting between Kerner, Lerner, and other high-ranking IRS officials.

Does someone from the Trump family, the Trump Cabinet, or even the Trump administration have to be assaulted or worse, killed, before we accept the fact that a growing number from the far-left have put a rhetorical bounty on their heads. If has-been actor Peter Fonda suggesting Barron Trump be "ripped from his mother´s arms and put in a cage with pedophiles" does not horrify you with the obscene brutality of its message, nothing ever will. From this cauldron of bubbling and putrid hate filled from the twisted minds of enraged liberal politicians, "journalists," entertainers, and academics, spews forth the dangerously

The latest cover of Time magazine criticizes President Trump´s tough border policy, by showing him looking down at a crying, two-year-old Honduran girl whose mother was detained after crossing the border.The photoshopped image is the latest ding against Trump and his zero tolerance policy, which led to the increased family separation of illegal immigrants. The cover is captioned, "Welcome to America."

Taxes: Whatever you think about the issue of taxing internet sales, the simple fact is that the Supreme Court has just guaranteed that people across the country will now be paying more in state taxes. It´s hard for us to see how this is good news. In its 5-4 decision on South Dakota v. Wayfair, the court overturned two previous rulings that prevented states from taxing sales of out-of-state companies. That meant a catalog company based in Maine didn´t have to navigate 45 state sales-tax laws to figure out how much each customer owed, and then remit that money to the

How´s this for sneaky? Sen. John McCain, not too long after seeking conservative and Republican votes in his failed 2008 bid for the presidency, went right after those same conservative voters without telling them, by egging on the IRS to ruin them. It´s the sort of political back-stabbing that defies belief, taking an active role in destroying the Tea Party, which was an authentic grassroots movement of local groups calling for smaller government. But sure enough, Judicial Watch has found McCain´s central role right there in the documents: Judicial Watch today released newly obtained internal IRS documents, including material revealing that Sen.

Sony Pictures Classics released a statement shredding actor Peter Fonda for his tweets, one of which called for 12-year-old Barron Trump to be raped — but the company said it would still release Boundaries, a new film co-starring Fonda.“Peter Fonda’s comments are abhorrent, reckless and dangerous, and we condemn them completely,” the film company said in an emailed statement late on Wednesday. However, the company went on to insist that pulling the upcoming Shana Feste-directed Boundaries, or trying to edit Fonda out of the film, would be “unfair” to the those involved. “It is important to note that Mr. Fonda

She removed the offending jacket, which bore the controversial phrase in white graffiti-style writing across the entire back section, before disembarking the plane upon her arrival. (Photos) By the

The Bush family has a famously adversarial relationship with English. It became clear this week that at least one of them is also illiterate where U.S. history and immigration policy are concerned. This was demonstrated when former First Lady Laura Bush took to the pages of the Washington Post to denounce President Trump for enforcing a statute signed into law by her own husband, George W. Bush. Even worse, she compared the HHS facilities where the children of illegal immigrants are briefly housed to the infamous internment camps where Democrat icon FDR imprisoned 110,000 American citizens of Japanese descent.
