Additive Manufacturing

It's Like Magic.

No college dorm room is complete without a printer. Or, in my case, two that I never use because engineers at George Fox get free printing. As it turns out, no space station is complete without a 3-D printer. The 3-D printer is part of something relatively new called "additive manufacturing." For as long as people have built things, just about the only way we've done it is by removing substance from a starting piece of material until we have the shape we want. We call that starting piece of material "stock," and in the past, we'd find the piece we want through subtractive manufacturing.

Now, things are different. Engineers entering the field are being taught about new processes of creation that will revolutionize the industry. In the future, manufacturing will be more efficient. That's a good thing because as earth's population grows exponentially and standards of living increase around the world, resources will become more and more scarce. History tells us that new resource supplies will be found, and more efficient processes will allow those sources to last longer. This will be one of those new processes.

So how does a 3-D printer work? Well to oversimplify things, they work like this: a layer of the building material in powder is deposited, a laser melts together the powder to form a very thin cross section of the item being printed and the action is repeated until you have the completed product. What's crazy is that this can be done with more than just plastic. Powdered titanium, steel and aluminum can all be used with 3-D printing.

As the technology advances, imagination will continue to urge it on. What will additive manufacturing be used to make in the future? Already it is used to create super-fast drones in half the time it would have taken otherwise. The most exciting thing about this is that the world still does not know exactly what it will make with additivie manufacturing.

Do as I say, not as I do.

Your eyes widen in horror as you stare at your phone. Beads of sweat begin to saturate your palm as your fingers tremble in fear. The illuminated screen reads, "Missed Call: Mom."

Growing up with strict parents, you learn that a few things go unsaid. Manners are everything. Never talk back. Do as you're told without question. Most importantly, you develop a system and catch on to these quirks that strict parents have so that you can play their game and do what you want.

"Friends" maybe didn’t have everything right or realistic all the time, but they did have enough episodes to create countless reaction GIFs and enough awesomeness to create, well, the legacy they did. Something else that is timeless, a little rough, but memorable? Living away from the comforts of home. Whether you have an apartment, a dorm, your first house, or some sort of residence that is not the house you grew up in, I’m sure you can relate to most of these!

There is nothing quite like family.

Family is kinda like that one ex that you always find yourself running back to (except without all the regret and the angsty breakup texts that come along with it).

No matter how long your class is, there's always time for the mind to wander. Much like taking a shower or trying to fall asleep, sitting in a classroom can be a time when you get some of your best ideas. But, more than likely, you're probably just trying to mentally cope with listening to a boring lecturer drone on and on. Perhaps some of the following Aristotle-esque thoughts have popped into your head during class.

Bob's Burgers is arguably one of the best and most well-written shows on tv today. That, and it's just plain hilarious. From Louise's crazy antics to Tina's deadpan self-confidence, whether they are planning ways to take over school or craft better burgers, the Belchers know how to have fun. They may not be anywhere close to organized or put together, but they do offer up some wise words once and awhile.
