Rather than building up plastic filaments layer by layer, a new approach to DLP 3D printing technology lifts complex shapes from a vat of liquid at up to 100 times faster than conventional 3D printing processes, University of Michigan researchers have shown.

3D printing could change the game for relatively small manufacturing jobs, producing fewer than 10,000 identical items, because it would mean that the objects could be made without the need for a mold costing upwards of $10,000. But the most familiar form of 3D printing, which is sort of like building 3D objects with a series of 1D lines, hasn’t been able to fill that gap on typical production timescales of a week or two.
Using conventional approaches, that’s not really attainable unless you have hundreds of machines,” said Timothy Scott, an associate professor of chemical engineering at U-M, who co-led the development of the new 3D printing approach with Mark Burns, the T.C. Chang Professor of Engineering at U-M.

Their method solidifies the liquid resin using two lights to control where the resin harden—and where it stays fluid. This enables the team to solidify the resin in more sophisticated patterns. They can make a 3D bas-relief in a single shot rather than in a series of 1D lines or 2D cross-sections. Their printing demonstrations include a lattice, a toy boat and a block M.

But the true 3D approach is no mere stunt—it was necessary to overcome the limitations of earlier vat-printing efforts. Namely, the resin tends to solidify on the window that the light shines through, stopping the print job just as it gets started. By creating a relatively large region where no solidification occurs, thicker resins—potentially with strengthening powder additives—can be used to produce more durable objects. The method also bests the structural integrity of filament 3D printing, as those objects have weak points at the interfaces between layers.
You can get much tougher, much more wear-resistant materials,” said Scott.
An earlier solution to the solidification-on-window problem was a window that lets oxygen through. The oxygen penetrates into the resin and halts the solidification near the window, leaving a film of fluid that will allow the newly printed surface to be pulled away.

But because this gap is only about as thick as a piece of transparent tape, the resin must be very runny to flow fast enough into the tiny gap between the newly-solidified object and the window as the part is pulled up. This has limited vat printing to small, customized products that will be treated relatively gently, such as dental devices and shoe insoles.

Barely a decade ago, 3D printers were hulking, expensive machines reserved for factories and well-heeled corporations. They were all but unknown outside the small circles of professionals who built and used them. But thanks largely to the RepRap open-source 3D printing movement, these amazing devices have become viable and affordable products for use by designers, engineers, hobbyists, schools, and even curious consumers.High Precision FDM 3D Printer

If you're in the market for one, it's important to know how 3D printers differ from one another so you can choose the right model. They come in a variety of styles, and may be optimized for a particular audience or kind of printing. Preparing to take the plunge? Here's what you need to consider.
Tied into the matter of what you want to print is a more fundamental question: Why do you want to print in 3D? Are you a consumer interested in printing toys and/or household items? A trendsetter who enjoys showing the latest gadgetry to your friends? An educator seeking to install a 3D printer in a classroom, library, or community center? A hobbyist or DIYer who likes to experiment with new projects and technologies? A designer, engineer, or architect who needs to create prototypes or models of new products, parts, or structures? An artist who seeks to explore the creative potential of fabricating 3D objects? Or a manufacturer, looking to print plastic items in relatively short runs?

Your optimal 3D printer depends on how you plan to use it. Consumers and schools will want a model that's easy to set up and use, doesn't require much maintenance, and has reasonably good print quality. Hobbyists and artists may want special features, such as the ability to print objects with more than one color, or to use multiple filament types. Designers and other professionals will want outstanding print quality. Shops involved in short-run manufacturing will want a large build area to print multiple objects at once. Individuals or businesses wanting to show off the wonders of 3D printing to friends or clients will want a handsome yet reliable machine.

For this guide, we will focus on 3D printers in the sub-$4,000 range, targeted at consumers, hobbyists, schools, product designers, and other professionals, such as engineers and architects. The vast majority of printers in this range build 3D objects out of successive layers of molten plastic, a technique known as fused filament fabrication (FFF). It is also frequently called Fused Deposition Modeling (FDM), although that term is trademarked by Stratasys, Inc. A few use stereolithography—the first 3D printing technique to be developed—in which ultraviolet (UV) lasers trace a pattern on a photosensitive liquid resin, hardening the resin to form the object.

Part of 3D printing's promise is that you'll be able to print useful things at home. And that's precisely what the Toybox from Make.Toys does: it simply and quickly prints toys. You just pick the toy you want from a selection on the company's website, hit the print button and wait. Your completed toy then pops out, ready for play.mini toy 3d printer

The process works, mostly: We were able to print toys like trains, track, castle parts and walls and small action figures from the simple-to-use web interface, and they were faithfully printed in sturdy, nontoxic PLA in a range of colors. But, like growing up, there are a few teething issues you need to get through first with the Toybox, such as the odd failed print and an interface with a few rough edges.
Not to put too fine a point on it, but the Toybox is cute. It's a small printer, less than 8 inches wide and a little more than 9 inches high. The frame is metal, with open areas revealing the printhead and removable print bed. The print bed is a magnetic sheet that holds tightly onto the base, but which slides off easily when the print is done. Because this base is flexible, you can remove prints by bending it until they lift off.

Spare print beds are cheap: three will cost you $14. The filament comes in 0.5lb (about 220g) reels that cost $10 each and fit onto the back of the printer. Although these reels are smaller than most and carry only 0.5lb of filament, you can use any 1.75mm PLA filament if you can work out a way to feed it to the printer.
The Toybox can't produce large prints: they are limited to just over 3 inches on each side. Considering the size of the printer, that is no big surprise, and the toys on offer are either small, or print in small parts. The train track, for instance, can be printed in 2-inch lengths that fit together to produce a larger model. The layer height (the thickness of the layers used to create the print) is also fixed at 0.2mm, which is pretty standard for small printers.

Make.Toys plays up the cute angle with the naming of the parts: the power supply is an "electron feeder" and the filament is "printer food." The food metaphor stretches to the colors as well: green filament is called apple, purple is grape, white is coconut and so on. It's a cute idea, but it also has to be accompanied by the warning that the filaments are not edible.

This is the first piece in ‘Next left: where to now for Australian progressives?’, a new series on what the election result means for the progressive side of politics and the path forward.To get more culture shock news, you can visit shine news official website.

Political commentators reflexively overinterpret election results. The story we’ve been told is that the Coalition’s win means that “Australian voters” have rejected Labor’s radical plan for reform of the tax-and-spend system, confirming that Australians prefer stability and incremental change.

Yet if one in 50 (2%) had voted the other way the pundits would have junked this narrative and told us, with great authority, that by endorsing Labor’s vision “Australian voters” showed they’re ready to embrace change.

One in 50 could have switched to Labor if Clive Palmer had decided to spend his $60m on a new house instead of an election. Or if Labor had chosen a more credible leader. Or if, a week before election day, a minister had been outed cheating on his expenses. Yet such a random event would then have caused the pundits to offer a sharply different analysis of the state of Australian society.
Poring over the seats won and lost, analysts have observed that many people voted against their economic interests, both at the lower end and the upper end. Some electorates dominated by low- and middle-income households, especially in the regions, voted conservative even though they would have gained from Labor’s plan to rebalance the tax system to benefit low-income households. Many in the wealthiest electorates shifted to Labor even though their taxes would be higher.

It’s a phenomenon noted a few years ago in the US. Donald Trump promised huge tax cuts for the rich and no change to a desperately unfair health system, yet millions of Americans on the margins voted for him. Trump duly delivered on his promises and they still support him.Labor’s inability to attract enough votes has been blamed on its unduly complicated message. Some say its marketing misfired. People were confused and so voted against their own interests. The answer is a simpler message marketed more effectively, and by a leader who is more relatable. And Labor must cut back on the promises of improving the tax-and-welfare system because voters could not understand it, or because they are prey to scare campaigns.

In other words, they blame confusion for voters’ irrational behaviour. But it’s more plausible that those who vote against their economic interests are as rational as other voters; it’s just that they don’t behave according to the pundit’s mental model – in which economic interests guide rational voting behaviour.For these citizens voting is less about economics than about culture. They are voting to protect a culture, that is, a social environment and way of life made up of values, behaviours and symbols that accord with their sense of who they are and where they fit. Those in wealthy suburbs who vote against their economic interests by supporting Labor or the Greens are also voting for culture; in their case, they want to change it.

The argument that “money doesn’t buy happiness” is typically attributed to the comfortable middle classes, but it can apply at the other end too. At the lower end, those who vote against their economic interests might be worse off under a conservative government, but they will feel better because of the psychic wages they receive from knowing their anxieties are being recognised and addressed. These psychic wages compensate for any decline in material living standards.

Progressives often have trouble understanding that culture can trump economics and around the world they are losing elections because the power of culture is growing while they continue to speak the old language. Culture now matters more than class, which is a dilemma for progressives in the cities who support the class interests of low-income people in the regions but represent a culture that many in the regions resent.

A week after a mysterious Chinese warship collided with a Taiwanese freighter, the Taiwanese ship's captain says that the collision was followed by a one-hour standoff as the Chinese vessel tried to force the Taiwanese freighter to sail to China.To get more chinese news sites, you can visit shine news official website.

In a press release issued on Aug. 1 by the Coast Guard Administration, Ocean Affairs Council, the Kinmen-Matsu-Penghu Branch reported that at 8 p.m. on Wednesday, the Yutai No. 1 was slammed into by an unidentified Chinese warship 19.5 miles southeast of Liaoluo Port in Kinmen, according to CNA. The Taiwanese ship sustained damage but none of its crew were injured, according to the report.

In an interview with Bloomberg, the 72-year-old captain of the Taiwanese ship Fu Shih-hour said that the commander of the Chinese warship tried to coerce him into navigating his ship into China's port of Xiamen. Fu said he refused the Chinese captain's demands and instead called the Taiwan Coast Guard for help.After receiving the distress signal from Fu, the Kinmen branch of the Coast Guard dispatched PP-10053 to the scene, and PP-10039 was sent to support it. By 10 p.m., PP-10053 established contact with Yutai No. 1 and confirmed that the hull was damaged, but there were no safety concerns and the crew was unharmed.

The Coast Guard said that after an extensive search, PP-10053 established contact with the People's Liberation Army Navy (PLAN) vessel. Fu told Bloomberg that when the Coast Guard arrived, he said they made it clear to the Chinese vessel that "we were in international waters and that we were under no obligation to follow their orders."

Fu said that the Chinese "captain wasn’t happy about it, but had to begrudgingly accept it" because the Taiwanese cargo ship was in international waters. The PLAN ship's captain then said that his vessel had been damaged in the collision as well and needed to return to Xiamen Port for repairs, according to the Coast Guard.The PLAN ship refused to stop and submit to inspection and ceased communications with the Taiwanese patrol boat. The Coast Guard said that due to the darkness of the late-night hour, the Chinese ship's number was not clearly visible.

Fu said that he was not able to clearly identify the Chinese ship in the darkness. He told Bloomberg that he could see that it was a military vessel and that it was "at least 100 meters in length."

A source familiar with the situation told China Times that the Chinese warship involved in the accident was one of two PLAN ships that were prowling in the Taiwan Strait near the island of Kinmen on Wednesday night. One of them has never been exposed to the media before.The Type 071 amphibious transport dock "Longhushan" was commissioned late last year, the tonnage of which is only rivaled by China's aircraft carrier "Liaoning" in the PLAN fleet. The other ship is believed to an unknown cruiser.

The Longhushan is 210 meters in length, far longer than Fu's description. The only Chinese warship classified by the U.S. as a cruiser is the new Type 055 which, at 180 meters in length, is a bit closer to Fu's description.

The first Type 055 destroyer in China's fleet, the Nanchang, was launched on June 28, 2017, and made its public debut at a naval parade held to mark the 70th anniversary of the People's Liberation Army Navy (PLAN) on April 23 of this year. Due to its massive size with a beam of 20 meters and a draft of 6.6 meters for a full load displacement of 13,000 t, the U.S. considers it a cruiser meant to rival the Ticonderoga-class cruiser, which is slightly smaller with a length of 173 m, beam of 16.8 meters, and draft 10.2 meters with a full load displacement of 9,800 t.

The camera on your phone is pretty spectacular. In an instant, it can capture a milestone in your child's life, a night out with friends or that particularly attractive slice of avocado toast in front of you.

Camera technology on phones has made giant jumps in innovation over just a few years resulting in plenty of phones that take outstanding photos. There's the Huawei P20 Pro and Mate 20 Pro that use triple rear cameras; the Samsung Galaxy S9 and Note 9 with mechanical dual-aperture; the Pixel 3 equipped with AI muscle and the iPhone XR and XS with a new HDR recipe. But nearly all of these phones are lacking in one area: video.

Phones can produce incredible photos and benefit from compelling features like portrait mode. But video shot on phones still lags dramatically behind in terms of image quality, dynamic range and low-light performance.

It's time for video from our phones to reach the same level of quality as the photos we take. Here are some ways companies can improve the way phones record video and a few video features that might be nice add-ons, too.The iPhone XR, XS and XS Max capture the best overall videos on any phone you can buy. This comes in part from Apple's A12 chipset and "Neural Engine," which speedily process footage.

Meanwhile, Qualcomm, which makes processors for Android phones such as the upcoming Galaxy S10, recently launched the new Snapdragon 855 chipset. CNET tested the new chip and found it was 45 percent faster than last year's Snapdragon 845 processor. This should help provide some extra muscle for Android phones.

It's only a matter of time before phones wrangle enough power to record and optimize video via AI and machine learning. Google is in the best position to do this since it already uses AI and machine learning to improve photos. Needless to say, video would require a phone to handle much more data compared to a single photo, and adding that extra burden of "enhancing" video footage quickly would require a level of power a couple of generations away.https://www.ttspy.com/live-phone-cameras-streaming-for-parental-con...

Picking the best camera phone in 2019 has become harder, with new front-runners in recent months, including Google, Huawei and Samsung. Surprise, they're all better than iPhone when it comes to taking photos. Apple's competition has caught up.

Our testing doesn't come down to the latest iPhone or the camera with the most megapixels. So much of the camera unit's quality is determined by how well the smartphone has optimized its software to snap photos or record videos.

Note: We're always updating this best camera phone list, and as new software tweaks happen and additional phones come out, we'll keep everything fresh and continue to test everything we get our hands on.

It's also important to consider which photos you'd want to capture, since some smartphone cameras can handle certain scenarios better than others.

We’ve tested all of the top camera phones in a multitude of lighting conditions, scenarios, and with a wide range of subjects. Knowing how each camera performs at different shooting tasks will help you determine which can capture the moments you want to save.

So, before you settle on the best camera phone for you, you’ll want to figure out your photographic needs. Great front-facing sensors with a wide-angle lens (or two) to snap better selfies? An array of different sensors on the back for versatile shooting? Knowing will help you decide which phone best suits your uses.

We saw a few deals for top-end snapping phones last year on Amazon Prime Day (which is coming on July 15 this year) - for instance, the Note 8 saw a top deal in the US with a dizzying amount off.

Google could also be doing a wider sale this year to phones like the Pixel 3, so it's worth keeping an eye on the price tags during July.https://www.ttspy.com/live-phone-cameras-streaming-for-parental-con...
