Best Device: 3D Printing

Is 3D printing the wave of the future?

Or maybe a better question is: what is 3D printing? This short video does a good job of explaining the technology and it's potential:

3D printing has already been used to create a wide variety of products. A few extreme examples are:

• a handgun made of plastic

• a motorcycle that was customized using 3D printed polycarbonate parts that has:
• won the 66th Annual Sturgis Motorcycle Rally
• won the Discovery Channel’s Biker Build-off competition
• set the AMA (American Motorcyclist Association) certified land speed record reaching 136 mph at the Bonneville Salt Flats.

The bottom line is anything you can design on a computer you could conceivably create with a 3D printer.

Pop culture even bought into the 3D printing trend when TV's favorite geeks got on board during an episode of "The Big Bang Theory."

Those who are watching this trend say the day will come when every household will have a 3D printer, just as every household now has a computer. But that day isn't quite yet.

The cost of 3D printer technology is still relatively high--the printer that created the gun in the above video cost $8,000. Having said that, take a look at the following screenshots from Amazon.com. These show 3D printers from $350 to $2200.

Keep in mind that there is a difference between “home-owner” quality and “industrial” quality. If you want to build “party whistles,” a $350 printer may work fine. But it will only build components no bigger than a 4 inch cube.  If you’re going to build motorcycle components for a bike that you plan to challenge the land world speed record with, you’ll need a more expensive printer—one that is capable of producing the size of parts you have in mind. The $1200 printer that shows at the top of the list on Amazon will build objects up to 8.8” x 5.7” x 5.9”. And that's not very big, though it may be big enough to build a hand gun--or a "Howard" doll.

Also keep in mind that the price will continue to drop. The first computers were expensive--and huge. The first U.S. military computer took up 1800 sq. ft. and cost the equivalent of millions of dollars in today's economy. The first home computer cost about $10,000.

The following is a chart of current and projected 3D printing adoption, courtesy of futurist Christopher Barnatt, the man behind the Explaining the Future YouTube channel.

With 3D printing, the sky is no longer the limit. Researchers say that 3D printing could make:

• vaccines
• human tissue from DNA
• structures on the moon or even Mars

Okay, let's not shoot for the moon quite this soon. Let me ask you this: what could a 3D printer do for you now?

Think about it. What do you want or need right now? Wouldn't it be great to have the choice of either going to the store to buy it or designing and building it right in your home?

As I look around my house, I can see several things. First, there's that little spatula in the kitchen that's wearing out, and we can't find another one just like it anywhere. Yet it's so handy, we hate to throw it away. With a 3D printer we could have a new one later today, or maybe first thing in the morning. Or what about that lid that cracked on the Bosch mixer? We've had it long enough that there's a new model out, and parts for the older model may be hard to find. But with a 3D printer, no problem. Or what about the roller that broke off the dishwasher rack? Same thing--I can order it and wait for a week (or two) to get the part--after I pay a hefty shipping fee, or with a 3D printer, I could have it made today while I'm out and install it tonight.

That's three examples and I haven't even left the kitchen yet. With this technology, the possibilities will be endless.

Keep an eye on this technology. I think it really could be the next best device in our digital age.

The networks created the content, and the audience "consumed" it.

Blogsy

I was in California for the weekend, and had left my laptop home, opting to take the lightweight iPad instead. Sure, I could have spend all the time visiting, but while everyone else was watching a movie on TV, I thought I'd make a quick blog post. I'd started working on the text the night before, and it was challenging. There's an old saying that goes something like, "Sorry the letter is so long--I didn't have time to make it shorter." This piece was like that. It took a while to get it just so.

But the text wasn't the only challenge. I wanted to use images--five, in fact. This was when I began regretting not bringing the laptop. For a device that is so easy to use, embedding images into a blog on an iPad is ridiculously hard. You'd think you could simply tap on an image in the photo stream and "git 'er done," but, alas, that would be too easy. After what seemed like two hours, I finally had all five images where I wanted them--then one vanished. It was there one minute--then somehow did a Houdini on me. "There has to be a better way," I mutter as I pulled up Google and did a search.

Minutes later I learned about Blogsy. The reviews were good--they claimed the app made working with images as easy as, well, as easy as touching and dragging. At this point, the $4.99 price tag didn't phase me. Don't get me wrong, there are times I won't spend a dime on an app. But since I'd already invested so much time into this one post, and realizing that if the app could save me time in the future, five bucks was a bargain.

So I downloaded Blogsy, and went to work. The main "how to" screen didn't mean a lot to me--I had to dive in and get my hands wet to really learn the program.

It was actually rather intutive. Once I set up my account, all my Blogger accounts came up.

From there I only had to chose which blog I was posting too, and I was in business. And I learned that even that isn't totally neccessary, because when it's time to post it you're given a chance to choose where to post it to. One nice feature is that once you have all your blogs listed, you can go to any posts or drafts you may have already started in any of your blogs, pull it up in Blogsy, and continue working on them.

The main feaure of course is the ability to manage images easily. This is what I got it for. Once my photo stream showed up, it was literally as easy as touch and drag. Keep your finger on the image, and once the picture shows up "behind" it, you can center it or drag it to either side.

The second feature I like is, because of how Blogsy is set up, it also becomes a blog management tool. As I have already pointed out, you can write, edit and post to any of your accounts from here. Not something I was looking for, but since I'm already here for the image feature, why not. It has the standard fomatting options--actually, it has a few I've never used before--like text color options and background colors.

If you like writing code, you can even change the screen and use the HTML feature. Not something I can see myself doing, but the option is there.

Perhaps the feature that really seals the deal for me though, are the help videos. Instead of doing a Google search, or going to YouTube to find how-to videos, just tap the settings button to the lower right.

Then tap on the How-To Videos line, and choose the topic you need help with. How easy is that?

The only snag for me came when it was time to publish my post. I tapped the button in the upper left and got this screen:

I didn't have a Flickr or Picasa account set up, and I didn't know I needed one. But without such an account, I couldn't get past this point. Once I understood this, I set up an account on Picasa, and then I sailed right through the rest of the prosess.

I was surprised, thought, at how long it took to publish the piece. When you publish a post with images, the images have to be uploaded to photo-sharing website--which takes longer than I would have thought. But then, I was uploading five images, so maybe the time wasn't that bad. It just seems much longer than it takes when I post from a computer. Still, the job got done. My blog post was online, and that's all that really matters.

All in all, I'm glad I purchased Blogsy. It's made by the guys at Fomola:

and I'll definitely keep an eye on other products they develop.

Social Media and Public Opinion

Social media does much to influence public opinion. This can be good--and bad.

On the plus side, social media allows us to find the village we belong to. On the minus side, social media polarizes us. It’s the old “double-edged sword" scenario—the very medium that allows us to find a global family we can relate to also allows us to more easily turn our backs on and ignore all others we don’t relate to, or agree with, simply by ignoring their views. This can breed a terminal case of groupthink in which we refuse to consider all points of view outside that of our village. And we can see this very thing happen every day.

Social media plays a big role in fostering social change. There are those who credit social media for fueling the advancement of gay marriage, or at least the use of social media to create the network necessary to see the changes we are now seeing. (Click here to see The Atlantic article.)

In fact, social media appears to the ideal tool to facilitate social change. Surveys suggest the same-sex marriage supporters use social media twice as much as non-supporters to share their views. And it’s obvious that they are gaining ground across the U.S.

This PBS article credits social media with uniting same-sex marriage supporters. And no one can discount the value of unity.

I think these trends show technological determinism at work, for it's obvious that our technology is driving a major shift in both social and cultural contexts.

More importantly, at least to my mind, is the fact that social media gives a platform and a voice to people whose opinions would otherwise be marginalized and lost in the noise of the public opinion arena.

Case in point: without social media I would never had heard the story of Robert Oscar Lopez. He was raised by two “moms,” and is in a unique position to offer a child’s perspective on growing up without a father figure. You can find the full essay here.

Lopez explains that his stance has been marginalized for forty-one years because he is a bisexual male raised by lesbian mothers, who is in a committed heterosexual relationship—which includes children he fathered—and he is a conservative. I’m sure you’ll agree that’s quite a combination. And I’m also sure you’ll agree his story needs to not only be told, but it also needs to be heard. And social media allows this to happen.

Social media also introduced me to Doug Mainwaring, a gay man who supports same-sex civil unions, but opposes same-sex marriages. Social media gives him a platform, a soapbox, if you will, a chance to get his voice heard. You can "hear" his voice by clicking here.

The medium does have a social effect. For without social media, none of these voices would be so readily available to the masses. And all voices need to be heard, just as all voices need to be weighed. Even our Supreme Court admits there isn’t much data on the consequences this issue could have on our society as a whole.

We do need to get past the tendency to allow social media to polarize us. While it’s good to find a global village of people who are most like us, we mustn’t allow ourselves to become like the China of old, and build a wall around our village to keep our enemies out. For if we do, we will also keep future friends away, along with innovations and improvements, and we will become stagnant. And when that happens, growing ceases, and dying begins.
