Internal criticism of other courses has suggested that our class provides “something” which isn’t often experienced in other courses. Did you find something unique in your own experience this semester? (There seems to be some consensus in that doing what we have been doing contains some merit, though there is some debate about what those merits are.)
This class shows hands on troubleshooting of mechanical, electrical, and software engineering. It was not like other lab type class where a lab manual supplies you with a step by step solution to the problem. This teaches students how to troubleshoot systems while doing it in a timely manor. The most unique thing about the class is the ability to submit the actions you did and receive points for those actions.


If someone came up to you, and asked you: “So, what good are these 3D printer things, anyway? Why would I want to have one?” What would you tell them?
I would tell them it's not just about the ability to print a 3d cube. It's more about the process of building you own robot from start to finish. It this case the robot is a 3d printer and then has the awesome power to help in any future prototyping that you might do. The building process teaches you why it's built the way it was. I would not advise anyone to buy a prebuilt printer before build one first, it's more than just a printer it's an experience.


Do you recognize the rough features we use on every computer today in its earliest form? Drawing comparisons between the evolution of that and the evolution of 3D printers, Doyle asks you to dream big. I want you to think about what we might try to achieve, both in the near term (cool but large ideas that we could do NOW if we had the means) and the long term (cool ideas which require developments in tech which don’t currently exist, ala sci fi).
Many of the feature from the early computers are the same, to name a few; the output is still a monitor, input is still keyboard and mouse, the way to make new files, the ability to copy text or files, and the way files are saved. To think big on the reprap evolution with tech we have now I see the ability to make circuit boards, wielding robots, and printing in metals. Dreaming in the future I hope to see the printing of, food, electronic components, and human tissue.


When you finally get your first self-driving car, would you prefer it to have locked firmware, where you would be unable to know whether it drove you past more McDonnalds' when it sensed your children in the back set, or unlocked firmware which you could investigate, but which under-qualified would-be mechanics could alter to suit their own tastes? Do you think the code would be more secure if kept secret, or if it were available to good guys and bad guys alike for community review?
I would want to know what my car is doing, so an unlocked firmware would get my vote. If the U.N. asked you to develop a sketch of a regulatory framework for 3D printing, what would you do?
I would think there are three sub frameworks or systems for a 3d printer. One system is just feed back loops to control the tempter of the tip and bed. Next there is a system that tells which motor to turn and wick not to turn. The last is some sort of timer. With those three things a printer could run, along with all other stepper motor items.
Do you think Doctorow's predictions for the future are plausible or likely?
If you are talking about that fact that computer are going to be everywhere, then yes I think he is right.
Can the copyright war be won? Is so, how? If not, where do we go from here?
It is not possible to win this war. From here we will go to the age of subscription, where we must log in to a server to get to our data, where computer run off of the cloud.


Write about something that interests you, related to the subject of 3D printing, which we have not covered in the course. This video shows the process of taking real life photos and turns them into 3d parts. This software is impressive, and I love to learn more about the rendering process. I know there is a 3d scanner in the back of the class but it was never talked about, some questions that interests me are how many pictures does it take? How accurate can the process be? And how does the software compute all the data it is receiving? So i guess my interest is more about 3d cameras and the software behind them then 3d printing itself.


What’s your impression of this use of 3D printing technology? Yes,I saw this video a bit ago and its amazing. This means YOU CAN PRINT ANYTHING! Would you buy a model of yourself? Would your parents buy one? I wouldn't buy a model of myself but, I could see myself buying a model of someone else. And my parents would get the entire family. Explain the merits (or lack thereof) in this business model. Its the same as a photo type business of today and portrait artists back in the day. How much might competition drive down prices in the future for these kinds of novelty items? The prize will drop but for better quality figures there might be a place for a market.


Now that you know a little more about the different types of 3D printing or other additive manufacturing methods, You should envision scenarios of a future where this technology is more widespread. What sorts of changes can we expect? What sorts of changes might we not expect?
The example of the printed toddler could be used in the future as a test dummy that could have other material for bones vs skin and ect.. I remember the mythbusters trying to center bones in arms and legs and failing but when printed they would be always centered. In a future with high res metal printers the design of jewelry would change all together. The things that would not change would be anything that could be sold cheap and mass produced, like cheap bobble heads, but if you want a custom bobble head 3d printing could be used. I also see big companies with "disposable" products, like apple making an iPhone that is unopenable so when i break you need to buy another.


We have a number of libraries on campus, as well as the one on allen street:
How many are you familiar with?
I know and use five: Paterno, Pattee, Earth and Mineral Sciences, Engineering, and Physical and Mathematical Sciences libraries.
Do you think any of them would be suitable for this?
I do not think there is room in any of the branch libraries but, I'm sure there must be a stop somewhere in the Paterno or Pattee Libraries.


1. Being able to create optical sensing devices on demand is something new, as typically we print passive components. What kind of implications can you imagine resulting from this?
This type of printing is amazing, but the implications are endless! Some that came to my mind are remotes without moving parts but your hands, and that ability will be great. The ability to make a product 100% waterproof and still have the ability to have inputs could be used in a lot of future products.
2. What sort of difficulty would we have in implementing light piping using our printers?
The ability to print clear plastic would be hard to achieve because of air gaps left by the low tolerances of our printers. If we could achieve the ability to print clear, we might have a chance in piping light.
3. In what applications might you find use for these sensors (contact switches, touch sensors, accelerometers, etc)? Do you have some project in mind where these would be useful?
The ability to print contact switches will further the reprap development by allowing us to print our own endstops. Being optimistic about accelerometers and touch sensors would theoretically allows us to print complicated devices such as iphones or Wii remote.


1. What do you think of bio-printing? What sort of legal problems or technical problems can you foresee?
Bio-printing seems like a great idea. the ability to print off skin to help burn victims would be a great medical achievement. But right now they are using the prints for drug testing, which is also a great idea. I see problems with selling human cells/parts, as it is illegal to sell something like a kidney, there is a fine line to what can and can"t be sold.
2. Do you think this might be extended to RepRaps for DIY bio-research?
I can't see bio-printing from home for a really long time, if it ever happens. It's hard enough to may plastic stick to a bed, to make living cells stick to a bed and eachother without killing them in the process just seems impossible out side of a lab.


1. Imagine that you were a dedicated member of the DIY gun project: What might you do now?
As they don't have a printer, there are two things I would. One thing is to get my hands on another printer, and the second thing would be to keep it quite so the same thing doesn't happen again.

2. Another article asks ”Should 3D printing, especially when it’s being used to create items like guns, be regulated? Can you regulate it?” Check your Blog #3 Questions 1 & 3 (and my comments to them) if you haven’t already. Do you have any more to say about this issue of 3D printer regulation (gov’t or corporate)?
Gun manufacturing should be regulated. But can it really be regulate probably not.
3. Guns (and other weapons) seem to be prone to prohibitions. What other 3D printable constructs might attract similar attention/derision/prohibition?
The only thing that is coming to mind would be a structure support part. If people put there life in the hands of a printer part and it fails I could see the government/people giving it some attention.


Comment on Makerbot’s position (as far as we know), Prusa’s concerns, and ownership of designs. Should we look for a new thingiverse?
First on Makerbot's position as being close closed source, I think this is a good idea for the Makerbot to make money and save the hard work put into it, but they might have lost the trust of the costumer. Prusa's concerns is that trust issue, Makerbot may not be out to steal all the thingiverse things we are going to wait and see or look for a new site. The question of looking for a new site or not lies in the question, do you care if Makerbot profits off of your design, and if I find out that that is happening I will be looking for a new site. But for now I'll give them the benefit of the doubt and stick with them for now.


1. It seems that 3D printing isn’t going to disappear, but the exact nature in which it will develop is not well defined. On that note, we currently place restrictions (DRM) onto our media to control distribution, with limited ‘success’. Do you think this might be applied to 3D printing? How or why not?
Yes,I think restrictions will be in the future of 3D printing. There are some ways this could happen, 1 way I was thinking about is sites like thingiverse could make a "membership" site where one would have to pay for access to the site. This would return profits to the person's file you download. I could see this something like "iTunes" pay a couple of cents and you could download the g-code for a part.

2. According to Bowyer, many people have a great idea (or perhaps a passion) that they love to tell people about. What is yours? Do you see this as a way to attract future mates? (or to get money?) Why/why not?
I see what you did here! I do have some GREAT ideas but i'm not all about tell other people quite yet, as my ideas are not complete an as Bowyer said ,"Information - unlike matter and energy - is not conserved.", so I will be keeping my ideas to myself until they can make me money. Or maybe a future mate :)

3. Professor Bowyer seems to think that 3D printing will finally kill intellectual property, and he sounds pleased about it. Do you think he’s right about ending IP? Is this a good thing, a bad thing, or somewhere in-between? First off i'm going to say that killing IP will lane in the "or somewhere in-between" for me. And as for this happening in the future I don't think it will happen. Right now I would guess that 30% of people (Americans) could set-up and use an old school 2D printer, for the 3D printer to take off in ever household people will need to be educated. The more educated people become more IP will be created. The only way IP could be killed by 3D printers is if the printers are so easy to use/build that no thinking would be needed to use them, but what kind of world would that be.

Blog#2 Adrian Bowyer

1. Do you think his goal of a ‘self-replicating universal constructor’ is feasible? What remains to be done to achieve this, or alternatively what would prevent such a goal?
How feasible is his idea... I would have to say that as of today it is unfeasible, but with time his idea make come to be.
2. The phrase “wealth without money” is both the title of his article and the motto of the reprap project itself. What does this phrase mean? (To him and to you if they differ). Discuss implications, problems, and possibilities associated with this idea.
His motto "wealth without money" means anyone with one of these machine would be able to own any and every "thing" at just the cost of materials. He clams that your friend could just print you off another machine at cost so almost everyone will have one, so I guess one can have wealth with money or you could say wealth with good friends. Materials would end up being one of the biggest problems, as more people needs for raw materials increase so will the price.
3. The Darwin design was released in 2007. It is 2012 now. Imagine future scenarios for RepRaps and their ‘cousin’ 3D printing designs (Makerbots, Ultimachine, Makergear, etc.) how do you think the RepRap project (community, designs, website, anything and everything) might evolve in the future? Describe as many scenarios as you can envision.
Much has changed sense Darwin, and I believe much more is in the further. For one I would think a circuit board printer is in the near future, but as for making stepper motors, that's a different story. I don't think it will go much bigger than that, open-source is great as long as there are a number of smart people chipping in. But as soon as it hits "mainstream" people will want to make money on there work and not just give it away. If the future does contain evolve(which it probably will) I believe it will happen slow with a lot of small changes.

Blog#1 Thingiverse Designs Entry

1. Useful- Adjustable Monitor Stand

I find this useful because of the money that would be saved just by printing this out.

2. Artistic/Beautiful- Flame Light Shade

This is a hollow model of flames, after adding a light source you have yourself a beautiful little light.

3. Pointless/Useless- Toothpaste Squeezer

First off who even needs one of these, secondly it just a big waste of plastic.

4. Funny- Bottle Opener

A wall mounted bottle opener is one of the best things I found on thingiverse, joust add a penny and screw it on a wall to get your drink on!

5. Weird- Creepy Alien Catapiller

I don't understand who would even want this let-alone waste the time to print it.
