3D Printing Precision Experiment with a Good Printer – Ultimaker 2

For quite a while here at 4PSA we’ve been playing with 3D printing. Why? Because it’s cool and because there are a lot of applications for 3D printing, even in the cloud. We don’t claim to be 3D printing experts, but we took a power user (read engineering) approach to 3D printing which may be interesting to some of you. So we decided to share some stuff with you in a series of articles dedicated to 3D printing.

In today’s article, we want to answer a pretty interesting question – just what level of precision can you expect from a FDM printer? Fused deposition modeling is the most popular and accessible printing technology. The market is already full of printers and even kits you can use to build your own printer that cost as little as a few hundred bucks. For the test, we used one of the best printers available – Ultimaker 2. And yes, Ultimaker 2 may be worth more than a few hundreds, but it’s still an affordable piece of engineering.

Quantum Computing Makes A Leap Forward As Moore’s Law Approaches Expiration Date

On April 19th, 1965, Gordon Moore wrote a technical paper that predicted the increase of computing power. He initially observed that the number of transistors per square inch on integrated circuits had doubled every year since ICs had been invented, and he later perfected the law doubling time to two years.

This month, Moore’s Law turned 50. To this day his prediction holds true, but it might not reflect reality in a few years from now. The reason? Our need for ever-smarter computers requires that we rethink the way we build them, and perhaps even the way we operate them.

Quote Of The Day By Joseph Heller

Sports equals long and healthy living for those who do it, entertainment for those who watch it, and profit for those who coach and manage. A by-product of sporting events is usually a piece of metal that gets hung around the winner’s neck. But is it of any real value to humanity? If you ask satirical novelist Joseph Heller, the answer is no.

How To Open A Can In A Zombie Apocalypse

Video games portray the zombie apocalypse as a fun departure from mundane affairs, but if it were to really happen things would probably play out differently. For instance, a seemingly trivial problem like opening a can of food would become a serious issue in the absence of a can opener, or a knife. Luckily someone has imagined this scenario and offered a solution.

CrazyRussianHacker doesn’t need an introduction, but for those of you who don’t keep tabs on the YouTuber’s activity, he’s got quite a few survival tips on offer in an extensive video library. Including how to open a can by simply rubbing it against concrete and then pressing the edges to pop it open. Of course, if you can’t even manage get hold of a knife during a zombie apocalypse, a sealed can of food is the least of your problems.

Quote Of The Day By Swami Vivekananda

Swami Vivekananda in 1893

Relying purely on luck has rarely yielded anything truly extraordinary. If you want to achieve something great, chances are you’ll need razor sharp focus and a lot of perseverance.

According to an Indian bloke who lived between 1863 and 1902, focus is crucial if you want to be successful. He didn’t mention a particular field or anything like that, but this memorable quote of his should apply just about anywhere.

If you could pick any place on Earth to kick-start a venture, what would it be? Startups are almost synonymous with Silicon Valley, but that’s the media’s fault. In reality, startup companies aren’t typical to America at all. In fact, some of the most innovative ideas today are being brewed in Europe and Asia.

To give everyone justice, a community called Founded X offers this cool website where you pick a country and get instant stats about things that matter to a startup – ease of funding, expertise markets, internet coverage/speed, office rental, corporate income tax, etc. You also get some conventional info regarding the weather, the national dish, the average price of a beer (always a good lifestyle indicator), currency, and population density.

Education Can No Longer Turn a Blind Eye To Unified Communications

School is mostly about students listening and teachers talking. In order to fill any missing gaps before moving on to the next lesson, we might need to pay closer attention to the student-teacher relationship beyond the classroom walls.

When the bell rings, any communication flow that does exist between tutors and tutees gets interrupted, making education one of the most fragmented processes we undergo as we develop into adults. In recent years, this problem has become easy to address.
