Before I took this class I was one of those people who said "Why would you want one of these things?". I thought you can just go out and buy everything, why would you wanna waste your time watching it print. But let me tell you, these little printer things are awesome. Just watching this technology rise is amazing. Being able to print out parts to build other items is great. It saves time on all the bs of ordering parts and waiting for them to come in. I really like how they began to take the printers into classroomson young kids to get them interested. It would really catch their attention if you printed one of their favorite action figures or what not. So to sum it up not only are 3D printers really cool but they are a great learning device and who knows maybe one day when you lose the back cover of your remote you'll wish you had a 3D printer to print out a new one.

Everyday there are screw ups on the printers whether it be a computer error or a human error. So what happens with that little bit of print that already started but is basically no good. Well it becomes trash because what good is it. Wrong. With new technology by Filabotyou will be able to recycle all of your wasted prints into new filament. But that's not the only thing it recycles. Get this, so once you finish drinking your plastic water bottle, go ahead and throw it into this recycling machine. It will be made into filament too. This is a great machine and I feel like it would be really cool to get one and see how it works and try to replicate it by using reprap parts.

This use for 3D printing is quite neat. It would almost be like a portrait but everyone is a little figurine. It's almost like a 3D version of a picture. I could see having a family doing something like this instead of a picture. Yes, I think I would purchase one. It seems it would be a great gift for a mom or grandma. Moms and grandmas love pictures, so what's better than a picture, a 3D picture of her family or her grandchildren. Seems like there could be a future in this line of work. And yes I could see my mom buying something like this to put on an end table.

It seems like the little figurines would sell decently but I think the printing your own head would be creepy. What would you would with just a model of your head? I can see using the other thing for decorations but I don't think anyone will want a model of their head just chilling in their basement or living room. Now I can see using this as a customization picture such as a family portrait where each one would be different. But lets say everyone they're doing figurines of a sports player. Is it quicker to just cast all of them outta plastic compared to printing each one. I guess that would be something to look into. For the price comparison you can see how fast makerbot knocked down the price for the model head compared to the other company. And as usual companies will find cheaper and cheaper ways to make these to ensure they have the lowest price.

I think these would be great in a technical class in grades K-12 to interest students in the STEM program. In high school and college I was involved in the BotsIQ program and it was created to interest students in STEM. It definitely worked for me because I choose an engineering major and it was definitely because of that. When I was involved in my high school BotsIQ team as an adviser a member from BotsIQ contacted me and another former teammate, who was also an adviser, to speak to kids in the about the program. This would spark interest at younger ages. So I believe that by getting these printers in classrooms that you would spark interest at younger ages. It would be great for a school district to by a few and allow students in 7th and 8th grade to learn about them and become real familiar with them, then have high school students replicate and build their own to use in class.

In the first article about STEM I definitely agree with putting these in classrooms and allowing students to build their own. And it's not like this could just be used for technical classes. As the article says it could be used for skeletal reproduction. Not saying the kids in that class would be doing the printing but having the tech class print out a skeletal system for them would be extremely cool. It would be even better for the class to print it out themselves.

I really like how in the third article they say about losing the back of the remote. I can relate to this because at home the back of my remote has been taped for the longest time and like he says tape just doesn't do the trick. But if we had 3D printers in our home we could just go print that part out and have it. This would be such a convenience.

I can think of a great scenario of having a 3D printer at a store. When I was replacing the head gasket on my toyota truck about 4 years I checking over other parts in the motor. I noticed the guide on the timing timing chain was cracked because it was a plastic piece. Not one store or company sold just this plastic guide piece, they all sold kits which were overpriced and included all types of parts I would never need. If 3D printing parts were available I would be able to go to the store and wait for about 20 to 30 minutes until the part was just printed. Instead I had to buy this kit, wait for a few days until it came, then put on all these parts just so they wouldn't go to waste. This would be a big change in automotive department. Many other parts such as plastic clips that hold in your dash would be able to be printed and save you a lot of time. These little clips tend to break over time just because they are plastic.

This technology of 3D printing has still not taken off in the world. It still is not known about as much as it should be. It could be put to use in so many more ways. I would not be surprised to see companies that produce plastic parts to have 3D printers laying around in their shops. This way product would not be sitting on the shelf wasting inventory. They would just print it off as customers came in and needed it.

In the first article The future of higher education: reshaping universities through 3D printing it discusses how libraries use to be used to share public knowledge. It would be about public conversation to share knowledge. Compared to now a days where they are a quiet place where no food or drinks are allowed. In a way I disagree with the author saying how the libraries should not have turned into quiet places. Sometimes when you're studying you like a nice quiet atmosphere, but there should be a part in the library where you can be loud to share ideas. I also like the idea where DeLaMare's library has a section of walls in whiteboard paint. When working on homework having a whiteboard to discuss ideas with a group. So the reprap would be great in an area where you can be loud and discuss ideas.

The only libraries I am familiar with is the Hammond Engineering Library, The Osmond Library, and the Patee/Paterno Library. I'm not a big fan of going to libraries much because they are so over crowded most of the time. I only go there to use a book that I do not own. If they were to put one in a library my guess would it go in the engineering library since those students would use it the most. Or you could have a designated room for it to go in.

1. If you make the 3D printer yourself there is no way they could control what you print. This regards to the part of the article where the printer will require a password to print a file part so that the part will not be patent infringed. But as everything goes who says you can't draw the part up yourself in a CAD program and print it off yourself? No matter what types of rules and regulations they try to put on open source printing, which is defeating the purpose of open source, people will find a way around them as people do for everything. So in a way this article doesn't support what I said before. The technology may find use in production model 3D printers but not in homemade repraps.

1. I really can't think of any implications these could bring right now. If I think of any I will re edit this and add them.

2. With our printers one big problem I could see is preciseness. Our printers our not as precise as the ones they use and I could see the designs getting deformed from our printers.

3. The contact switches with the built in LED's would be great for light switches. This way when you walk into a dark room the switch would be lit up so it wouldn't be hard to find the light switch. I do not know about any projects but in a few labs I have used accelerometers. These would be great in the lab.

1. I'm really not sure what I think of Bio printing. I mean if it worked 100% correctly it seems like it would be great. Especially how you could deposit cells directly into a wound for the military to make it heal faster. The only type of legal problems I could forsee is copyright or patent infringement with copying certain parts.

2. I think it would definitely extend DIY research. Smaller universities with small funding would use the rep raps to do research. It would help them significantly because they may not be able to afford large expensive machines for research so rep raps would be perfect for them.

1. I would probably attempt to obtain a license if I was a dedicated member. This way you wouldn't be in the "gray area" with the laws. I'd want the process to be as legal as it could be.

2. I think it should be regulated. It would be nearly impossible to regulate it though. How would you be able to control what people printed off at their homes if they already had the file. I could see it being regulated on thingiverse such as not allowing weapon files to be posted but that is about it. It's more of a safety issue than anything because would you want a criminal having access to weapon files, but then again if they want to achieve this I'm sure they would find a way.

3. Anything involving drug paraphernalia would definitely attract the same attention but that's about the only other thing I can think of.

It seems that the new makerbot 3D printer will be closed source. This will not allow any to replicate their design. Do you think makerbot was getting sick of everyone copying their designs for free instead of having to pay a hefty price for all the dimensions and such? I don't blame them considering the fact of how much more money they could be making if they charged everyone a fee for the dimensions and design. Except with them doing this it kinda defeats the whole purpose of open source printing. Prusa is concerned because he does not want makerbot to own all of his designs that he uploaded to thingiverse. He wants people to be allowed to use his design so he uploaded them to his own website. It seems as we might have to begin to look for a new thingiverse, but like the post says hopefully this is just some mumbo jumbo added by lawyers.

1. No I do not think this will be applied to 3D printing. How can they place a control on distribution when you are building and making parts from your own machine. 3D printing definitely isn't going to disappear. It has just begun and will only get larger.

2. I do not have a great idea but I do have a passion. My passion is Jeeps. I love working on Jeeps. Anything from putting on lift kits, doing custom modifications, and to even changing oil. My friends always joke and say once you get me on this topic I don't stop and that's the truth. It's really not a way to attract future mates because few girls are into the offroad/Jeep scene but you do meet a lot of people who share the same interest as you.

3. I do not agree with him. I think intellectual property will never die. People will always be constantly making patents and copyrights and other people will always be making illegal copies of it. So in a way it will put a damper on intellectual property but it will never die.


Blog 2:

1. I do not think the goal is feasible. My reason being is that how many people are actually going to want to take the time to build one of these machines or how many people are going to want to set up this machine to print a part when they can go buy one. Some people, such as older folks, have a hard enough times using cell phones, imagine them trying to download a file from the internet to print a part they need.

2. I think the phrase means you can build anything you want and you don't have to be rich. Once you have this machine your limitations of building objects is almost endless. This is where the wealth comes in. Calling the objects all your "wealth" where you don't have to have "money" to operate it. The only item to have to keep purchasing is the plastic used to build the parts. Only problem you may have is when a part breaks on the machine and you do not have another machine available to make the part.

3. In the future I can see the RepRap machine being able to make designs quicker and put out items a lot faster than it can now. There may be also larger versions of the machine for larger scale objects.

1. Useful

Fry-Pod for Cup Holder with Locking Catsup Tray

How many times are you driving down the road trying to dig through the fast food bag to grab your french fries you just ordered at the drive through? This will make eating your french fries in the car a lot easier.

2. Artistic/Beautiful

Flame Light Shade

I think it takes some serious artistic skill to make something like this. The design of it is just very unique.

3. Pointless/Useless

I-phone Stand

I would never buy a stand for my phone. What would be the point of it?

4. Funny

Chinese Throwing Spork

How can you look at this and not laugh? Chinese Throwing Spork.

5. Weird

Autumn Egg Cup

If you have eggs sitting on stands I think that would make you very weird.
