Main | Class Blog

This page is for the class blogs we need to write for different topics about the 3-D printing.

Blog 1: Thingiverse

We had to find different items on the Thingiverse that inspired us.


Brain preview featured.jpg

An item that is amazing/beautiful

The model of human brain is really detailed and we can see the structure of it. I don't agree with the author said it's rather coarse, it isn't creepy and I think it's beautiful.Source






3d.jpg

An item that is funny or strange

On the first glance of this object it reminds me of the Iron Man, it was made of 3 type of colors. Although it's very tiny, but it looks like the same as the original one with every detail on it. Also it is curved and I don't know how to do that by 3D printer. Source

An item that is useless

We already had a perfect industry for plastic box. They are cheap, strong, large and useful, why should we take a long way to use 3-D printing to make it? I don't understand.Source






3d1.jpg

An item that is useful

Do you ever imagine you can made one of your own phone case? I want one badly. This allows you to use your needs and ideas to made it that different from others which is convenient.Source






AutoTran.jpg

An item that surprised me

There is a video about this object in the source link shows the operation of it. It works smoothly, every part of it is perfectly matched and rotating very well.Source








Blog 2: OSE project

We were asked to research about OSE projects and respond to the following:

A) I want your general impressions of the OSE project; positive, negative, utopian, etc. Please do a bit more research than just viewing the video, as it is now several years old and they have made some progress since then. Links to more recent videos and media will earn you a better blog.

B) The New Yorker magazine recently had a fairly critical article regarding Marcin's OSE project. Find/link that article and summarize its critique. Marcin had a response to that: I'd like your response to both of these pieces.

C) Imagine we want to create capabilities similar to what Marcin has made at PSU (something like an OSE student club, or another effort). I don't think the administration or trustees would support such a thing, but there might be professors who are interested in supporting such a thing. Do you know any of them? What do they do, and why do you think they would be interested in such a project? Imagine you are looking for allies to do such a thing. Whom is on your list and why?

Answers:

A) It's really hard to determine whether the Open Source Ecology is positive, negative or utopian. Definitely it is amazing and attractive, imagine just by downloading the blueprints from the website and build it on your own. It will save you a huge amount of money and because you built it, when some problems occur, you actually know the solutions. Marcin built a tractor in his farm, also he listed total of 50 things that need to be open sourced, here is the list. Source When I check on OSE projects site, I found thrilling that they are trying to make Microcars.

However there are still lots of issues may happen to this project. One of the main and the most important thing is the safety issue. First, the open source needs to make sure there is no error on it. Second, this requires you understand more mechanical knowledge rather than a normal person. Because if such a big thing like tractor has some problems, the result maybe very dangerous.

B) The New Yorker Magezine talks about the OSE which can be found Here.The author Emily Eakin criticizes many problems that Marcin had, and the first one is the worker on his farm has more enthusiasm than skills in building these things. Secondly, the author questioned the ability to produce food by using their own machines. The article said it can't even satisfy the labors' needs. I don't know why the author trying to criticize the OSE by telling us that Marcin is on the diet and his punctual, it doesn't make any sense to me.

However, the Marcin's response was well organized and can be found Here. He is trying to proposing a more optimistic representation to his work and by listing the answers to the questions, it become really convincing. Also he admit there is some problems because it seems unrealistic, but they are working on the way to turn this into a better result.

C) I honestly don't have many thoughts on this question but I'm assuming some of my Design course professor would like to join into this group, like Eagle Leland, Lamancusa. Or I also know we have an Ecocar team in Penn State which may also be interested.






Blog 3: Robotic Hand

Read and respond to this: http://www.kansascity.com/2014/01/31/4790811/kansas-teen-uses-3-d-printer-to.html

A.Who created this design and when/where was it done?

B.If you wanted to make one, where would you go to get it?

C.How many news articles can you find which reference this technology?


A.The idea came from Ivan Owen and Richard Van, and the metal prototype was created in November 2012. At January 2013, the 3D printer version has been put online with free instruction. Then 2 months ago, Mason Wilde, 16 years old high school student, used a 3D printer in the Johnson County Library made a Robohand.


B.I will get the CAD files from the Thingiverse. Also there are some other tools needed like a drill, a pair of pliers, and about $60 worth of materials, including a dye kit, nylon string and hard plastic for the gauntlet. Then I will go to the 3D printer and print out parts and assembly them together.



C.Here are some relevant news that I can find and I can be sure there are more:


“Kansas Teen Uses 3-D Printer To Make Hand For Boy”, http://www.wibwnewsnow.com/kansas-teen-uses-3-d-printer-make-hand-boy/

“Teen Crafts 3D-Printed 'Robohand' for Fingerless Boy”, http://www.pcmag.com/article2/0,2817,2430396,00.asp

“'Robohand' given to West Michigan preschooler proving to be life-changing”, http://www.mlive.com/news/grand-rapids/index.ssf/2014/01/robohand_given_to_preschooler.html

“Boy Receives 3D Printed Prosthetic Hand”, http://www.ubergizmo.com/2014/02/boy-receives-3d-printed-prosthetic-hand/







Blog 4: Response to blog 2

I thought that many of your responses to blog 2 were thoughtful, and I'd like you to reflect on the thoughts of your classmates. Read your teammates blogs, as well as the blogs of at least 5 other students in class this semester. I would like you to find any thoughtful points made by others which you did not note yourself in Blog 2.


Carson Geib

Carson thought that Marcin's idea is too utopian. He had a valid point that as being an agriculture engineer, by looking at the tractor that Marcin built in six days, there are many basic parts that are not qualified. It can be only used for some situations that farmers can't afford it or in some developing countries, but can't apply for more expectations.

Tom Vassa

Tom put the faith in the OSE project and it is on the right direction. I don't agree with him that Marcin should focus on quantity over quality. Quality is always the first priority in hand-made machines. Also, Tom had found the original New Yorker article by retrieving a pdf.

Kevin Moyer

Kevin well analysed how Marcin respond to the New Yorker Magazine's article. At the mean time, he actually suggest an interesting idea that OSE project can be similar compared to THON. I'm not familiar with THON but it is really thrilling if those kids can get benefits from OSE. We had the same idea on OSE is perfect for the ME 340 course, which is for engineering design.

Vincent Iachini

Vinni is positive on the OSE project, he found the things on the 50 tools list is very interesting, especially on the "Global Village Construction Set". It is very convenient and has a bright future.

Jessica Mewkalo

Jessica thought our current society is already in a particularly stabled environment. The products chain is fully functional and cycling. There are no needs to bring another structure of society. However, it isn't fair enough that the New Yorker Magazine to criticize Marcin only focused on the disadvantages.




Blog 5: Media Timeline

Look through the RepRap Media timeline page (accessible from our SCRUG main page) and attempt to identify the most significant events from the last few years. If you think there's something missing from the timeline, add it and claim it for XP - but include a summary! What projects continue to recieve coverage/press over time? What projects seem to have slowed or stopped?

Here is the timeline. Timeline

A) An event very important in the progression of 3D printing technology (open source or not)

On the November, 2008, Thingiverse is launched. It is the first website where people can upload their own 3D models for people to print out, open sourcing at its finest.I mentioned it as the very important because it had benefit so many people including us. People can upload all the things they want or hope to make and share the ideas with people. It offers a great opertunity and stage to help the developing of 3D printing. As I said, we are stilling using this website, I would definitely assume it will keep growing with a bright future. [www.thingiverse.com site]

B) A not so important event in the progression of this technology (something overhyped perhaps?)

When I looked at this article 'A Merry Maker’s Christmas' Source it is entertaining.However, I don't think it deserved to be published on the timeline. First, it is not a new technology be created. Second, the article just talks about a suggestion that we can make our Christmas gift from 3D printing. Although I would definitely bring this topic to class to chat with my friends, it is not revolutionary enough to be put on the timeline, it seems overhyped. Timeline should include all the amazing inventions and meetings or decisions, it can quickly feed the information to the people who want to know what important happened. We can use this article as an promotion of 3D printing, shows to people who doesn't know well about it.

C) Something which you found interesting which you would like to think or speak more about. This might overlap with #1 a bit, depending.

I found this article Source interesting. As we know, the 3D printer we currently used, or those printers on the market has a common disadvantage, that is they only able to move along straight lines, but the robot arm from this printer is able to print in all directions, which means that the arm can move the printer head along complex, curved surfaces. This invention reduces the printing time and improves the quality of the printed surface. I don't know how much it would cost but it greatly enhanced the capability of the objectives we want to print.They ran several tests to prove that it is functional and can be produced on the market.

Also I found the timeline on July 23rd 2013 had some errors. The article linked is not the right one.



Blog 6: Future Thought

What projects do you think would be a logical next step for us to pursue? These may be things you see others doing elsewhere, or ideas of your own to push the boundaries of what we are using. We have been putting in significant effort to upkeep the printers we have, but as we get good at that, where might we go next? What would enhance our capabilities or put a new twist on what we are doing? Can we make a composite printer? Do we need more dual extruders everywhere? I know some of you have had ideas on this subject already, so please document them in this blog for everyone.

Firstly, I think everyone is doing a very good job in this class. We have a small presentation at the beginning of each class to tell us something new about 3-D printer. Also students are putting a great amount of effort on the printers. As I know some of them stayed until 9 or 10 pm to try to fix the printer. For next step I would suggest to keep up the work to repair those printers, some of them still has a long way to go, several teams needs the hot tips for the printer. After we finish this, I'd like to build one RepRap 3-D printer with my team members. We already learned the knowledge from fixing it, it definitely would help us gain a deep understanding of how it works.
