What is a 3D printer? As explained by http://www.3dprinter.net, a 3D printer can “print” in a plastic, metal, nylon, and over a hundred other materials… it can also print manufacturing prototypes, end user products, quasi-legal guns, aircraft engine parts and even human organs using a person’s own cells.
How does it work? The printer creates a three dimensional object by building it layer by successive layer, until the entire object is complete. This is called “additive manufacturing”, which saves on unused, wasted materials. Each of these printed layers is a thinly-sliced, horizontal cross-section of the eventual object.
To start off with, a 3D printer needs to have instructions, and a file. The file – a Computer Aided Design (CAD file) – is created with the use of a 3D modeling program, either from scratch or beginning with a 3D model created by a 3D scanner. Either way, the program creates a file that is sent to the 3D printer. Along the way, software slices design into hundreds, or more likely thousands of horizontal layers. These layers will be printed one atop the other until the 3D object is done.
Sparking Students Interest in Creating “When you produce something yourself instead of purchasing it, that changes your relationship to it,” says Chelsea Schelly, assistant professor of social sciences at Michigan Technological University explains on http://www.3ders.org . “You are empowered by it.” Schelly began her research by studying a teacher workshop coordinated by 3D printing guru Joshua Pearce, an associate professor of materials science, and electrical, engineering. During one of the local high school workshops, a teacher demonstrated how he can create a mechanical replacement part, instead of running out to purchase it. “He needed a snow blower part that would normally cost $200,” Schelly says. “Instead, he made it himself and saved the money.” Since this workshop, students routinely beg to stay after and create things on the printer.
Past and Present 3D printing has technically been around since the 1980s, but there have been many upgrades and improvements since. According to m.t3.com, the gadget website, Hp is planning on getting into the 3D printing business. Hp will launch it’s 3D printer next year, and while this will initially be for businesses, they do not see this lasting very long. Hp is also researching ways of bringing down the cost of the printers, and to speed up the 3D printing process, which can take from 8-10 hours currently.

With Good, Always Comes Bad bbc.com reports that the first gun made with 3D printer technology was successfully fired in the US in May of 2013. Also, downloads for 3D-printed the Liberator gun design reached 100,000 in May of 2013. The BBC’s home affairs correspondent, Dominic Casciani, said in response to this growing concern “ The worst case-scenario would be a cheap and 100% reliable device that could be made overnight and then destroyed after just one use, disposing of crucial evidence to pin to a suspect”.

Triton Gay Straight Alliance members exhibited both the dark and bright sides of what it is like to be of a different sexual orientation than others during their national coming out day on October 14th.
The event starts with people who entered into a dark room where hateful slurs and phrases are plastered around the room including HOMO and FAG while members yelled hateful sayings to you while a projection of those who committed suicide due to the same types of bullying are displayed. This was to give insight to what most people today who are LGBT nowadays are experiencing while dealing with the taunts and torments of others.
After seeing the negative side of things, you are taken to a bright room where it celebrates being who you are. Opposite of the dark room, phrases that are plastered around the room are of politically correct terms including homosexual and transsexual and a sign that displayed the rainbow with the phrase “Angels Above Us”.
Members of the group wore t-shirts that displayed their sexual orientation on the front with the question “Can you tell?” on the front.
This years event took a complete turn in comparison to last years as it not just showed those who lost their lives for being different but took you inside the harshness of their lives. President of TGSA Shakena Kirksey Polk, 31, said that this event was needed as it doesn’t focus on the bullying of those who are LGBT, but those who are bullied everywhere.
“The school needed this exhibit because people always here about it happening, but hearing it and seeing it are two different things. Individuals come in and it is completely anonymous and they would write about it and how they feel about it. We want to make this a yearly event to promote anti-bullying not just to our members but everyone.” Polk said.
The event left those who attended with emotions as to how this continues to be a problem in society. It was not just an emotional time for visitors but for the members of the club. Mia Greene, 27, said that she has been there but it made her a stronger person.
“This was personal for me especially after coming out in high school, I heard the terms, I was told I wanted to be a man, I got jumped, I fought, but it made me strong. I am glad we can raise awareness, I wish we could have had this in high school.” Greene said.
TGSA is a club that provides a safe and non judgmental zone that welcomes all as there is no difference, it is a place of just being. TGSA member Marguerite Incardone, 20, said she hopes this event continues even after they all graduate.
“This doesn’t focus on LGBT, but bullying in general. It affects everyone, they are strong people and great for being who they are. Why make fun of what makes everyone unique.” Incardone said.
Students and faculty waited in line to get a taste of the roasted corn during the 2013 Corn Roast presented by Program Board.
Each year, the event brings students not only corn with all the fixings but also games, music and prizes as they partake in activities from various supporters including the United States Army. In addition, all the clubs were out looking to promote themselves and get students excited about the extra curricular activities while attending Triton.
“It was a great time for fellowship and we are really blessed, we had 20 people sign up for TBC and we are on our way to get the word out” said Danny Holowicki, President of the Triton Bible Club.
More students expressed that this event is a solid mark in Triton history as it unites both students and faculty outside the classroom. Student and Program Board member Alexis Gonzalez, 19, said that this event was a way to get students involve with the administration.
“Corn Roast is the best way to bring the Triton community together,” Gonzalez said.
Although the weather took its toll in the evening session of the roast resulting in moving the event to the cafeteria, everyone still enjoyed the festivities.
Although the event ended in a down pour, the big smiles and full bellies of everyone on campus made it all worth while.
