Today the 3D printing group continued with our plastic holding device. Last class we were able to cut out two circles to attach to a lazy suzanne, but we then encountered the problem of how to keep the spools of plastic contained in the spool form. We decided to put a peg in the middle to keep the circular shape. This involved drilling a hole through the middle and using the scroll saw to cut out a circle with a diameter of 3.5 inches. We were successful in our attempts and hope to have the plastic holding device mounted and working in the very near future. Pictured above is Kelley cutting out the circle on the scroll saw.

More Modifications for Computer Cooling
Posted on 3/29/2012 10:31:00 PM by Aaron with No comments
As part of our continuing efforts to reduce the performance of the 3D-printed base, today we added a small aluminum wedge to the inside of the base. Hopefully this downward-angled wedge will direct water onto the processor and mitigate the problem caused by the space between the area where water flows and the processor itself. We will run the first set of tests for this modified part tomorrow.
Plastic Container Design Modification
Posted on 3/29/2012 09:04:00 PM by Anonymous with No comments
The original inspiration for the design of our plastic container was a bobbin used on a sewing machine, which is pictured to the right. As we moved forward with this design, we realized that this design would not be effective in containing the plastic. Now we are moving towards designing a "cage" to enclose the plastic as it sits on the lazy susan we cut and constructed last class.

Self Contained Cooling
Posted on 3/28/2012 10:59:00 AM by George Kaplan with No comments
Today we tested our simple part while overclocking the processor. Several members of the group also began analysis of our test results in Excel as well, aggregating temperature and time data and graphing. This week we plan to make some modifications to our simple part in order to increase its effectiveness.
Spool Prototype Progress
Posted on 3/28/2012 10:37:00 AM by Celia D'Agostino with No comments
Today we worked on creating a prototype spool that will essentially hover and rotate over the Makerbot. The spool will feed plastic to the extruder from above the 3D Printer. The circular metal piece shown in the picture on the left acts as a lazy susan that is made to bear weight. So as pressure is added, it becomes easier to rotate. This factor played a huge role in the type of wood we needed to use for the prototype. We were able to find a heavy enough piece in a nearby Woodshop class to work with. As of now, we have cut out two round discs from the wood that will be used to sandwich the lazy susan and ultimately create a rotating base for the plastic to go on. That is all we have on the prototype for now but we are moving forward!

Cooling Group Update
Posted on 3/28/2012 09:26:00 AM by Alex Gailor with No comments
Testing continued with the first test of the simple computer cooling system. The simple cooling system is a cheaper and simpler water block that is easier to manufacture. It is even quite simple compared to competing devices. The test results of the simple part exceeded expectations, keeping the temperature of the CPU comparable to that of the test results using competing devices under the same processor load. This means the more cost effective prototype of out two designs works better than our more expensive design, making the simpler design a clear choice for actual manufacturing and sales.

3D Printer problems
Posted on 3/27/2012 08:39:00 PM by Anonymous with No comments
We are still having trouble with our printers software recognizing the computer in school. So, Sam took it home to see if it still works on his home computer. We've looked at different forums where people have addressed the same problems we are having; so hopefully we'll have the printer up ad running in school soon!

Plastic Carraige Progress
Posted on 3/26/2012 05:40:00 PM by Sam H with No comments
Our group has recently decided to design a carraige to hold the plastic used for the Makerbot Thing-O-Matic. Today, three group members began sketching possible solutions using Autodesk Inventor. Most designs included four wooden arms connected to a round lazy susan that would attach to the top of the printer. Ideally, the plastic spool would rest on the lazy susan and the extruder motor on the printer would pull down any amount of plastic needed. In theory this should make the printing process more efficient and less cluttered.

Maple Avenue Engineering Competition
Posted on 3/24/2012 12:42:00 AM by Emma Rocco with No comments
This evening was the second annual Maple Avenue Engineering Competition, a wonderful event to show the accomplishments and creativity of young students. The task this year was to create a device that could putt a golf ball into a hole. While this task may sound simple, each team had to incorporate at least three simple machines, be creative, as well as perform and work well as a group. Paige, Will and I were there to help out the teams as mentors if they needed an extra hand. Every group had a fantastic and unique approach to the problem and were so driven they needed very little help from us or any of the other adults. I was amazed with the level of work these students were able to turn out in such a short time period of two hours. Groups used motors, inclined planes, screws, wedges, pulleys, wheel and axles, and gears to create their project. They used techniques that I couldn't have even dreamed of when I was in middle school. I was very proud to say that I got to witness the making of these devices and I greatly applaud all the technology teachers at Maple for their hard work. Even though tonight was a competition, the real winners are all the students who attacked this challenge with enthusiasm and made their ideas a reality. Keep working hard, be creative, and think big.
Above are pictures of Team 1 working hard on their project, as well as Paige and Will ready to give a helping hand.

SCC milling update
Posted on 3/23/2012 07:21:00 PM by Howe_john with No comments
The Self Contained cooling group has been doing a lot of work on the mill this past week. We started by finishing up our simple design part. This was exciting, however the simple design block was as good as a paperweight until we created its own mount. The mount design had to be slightly modified from our previous one because the tubes go straight into the top of the block rather then from the sides. That being said it was a quick fix and we managed to mill the part before the week had ended.

Today in class the makerbot group moved forward with making modifications to the printer. We have decided the first thing we will add is a container to hold the plastic while printing. We have come up with a design and hope to have the model completed by next class and ready to test.
Outside of class, a few of the team members are planning on going to the middle school tomorrow evening to assist with their engineering competition and to get students interested in pursuing engineering at the high school.

Wood, Lasers, Ribbons, and Shoe Polish
Posted on 3/14/2012 11:54:00 PM by Shane with No comments
We are not going to silkscreen the Head of the Fish ribbons, we are going to engrave them in the laser cutter. Mr. Gallagher and I stayed after school until 4:30 working with Inkscape trying to line up the ribbons. We cut one of the sample plaques and although it was a little bit off, it still came out great. Once we make our final 'tweaks', complete our templates, and cut out our plaques, we will really get our money's worth out of the laser cutter. It could take up to ten minutes to complete one plaque. Multiply that by 150 and it will take 1500 minutes just in cutting time. (That's not factoring in everyone else that needs to use the laser cutter or the time in between each plaque.) Not every plaque is going to be the same, so changing our print files and keeping track of every plaque will really use up time as well. After we cut our the ribbons and label on the face of the plaque we have to fill in the crevasses with shoe polish, or paint. Maximum efficiency is our goal, while still providing flawless quality.
More Cooling Test Updates
Posted on 3/14/2012 11:53:00 PM by Shane with No comments
Today while continuing to mill the aluminum part, we began a new type of test: we are now putting a commercial water block in our test system to compare the performance of our 3D printed base directly to that of commercial water blocks. The first tests did not look as promising as last time, with the commercial block beating ours by roughly 5-7 degrees Celsius, but after we modify the 3D printed part and run another round of tests, hopefully the results will improve.

The Deal Maker
Posted on 3/13/2012 09:17:00 PM by Shane with No comments
The final step in proving we can handle the "Head of the Fish" plaque project is applying the 'Head of the Fish' and 'Regatta' ribbons on the face of the plaque. It will be a classic silkscreening process, but first we need to either find a template, or create one. Today after school I started working on recreating the logo in Adobe Illustrator. It is coming alone, but I will need to spend a good amount of time to make it nice. This could be the deal maker or deal breaker of this project.

Cooling Group gets its First Test Results
Posted on 3/13/2012 09:55:00 AM by Shane with No comments
The first results from tests done on the 3D printed base for the Self-Contained Submersion Cooling group have started to come in. We haven't started to analyze the results yet, but on a stock Intel i7 920 processor running Prime95 at full speed on all eight threads, temperatures stayed in the 60 to 65 degree Celsius range. There are still modifications we can make to improve this part, but these preliminary results look very promising! Please look forward to more updates on test results as we continue testing throughout the coming weeks.

Change of Plans for 3D Printing
Posted on 3/12/2012 09:35:00 PM by Shane with No comments
Today the 3D printer group decided to establish our direction for the next three months. We decided on doing three things. First, we are going to finish the arduino project we started. Second, we are going to come up with a couple of fixes to the maker bot, which we are each independently brain storming as homework. Third we are going to video tape and post our progress of our additions to the maker bot.

RPI Aeronautical Engineering
Posted on 3/12/2012 09:28:00 PM by Shane with No comments
Along with the civil engineering demonstration, we also received a presentation on aeronautical engineering during our trip to RPI. Two professors showed us their wind tunnel and explained its inner workings. The machine blows bubbles which shows the airflow through the case. They showed us what turbulence would occur at difference angles. Also, they explained the characteristics of objects with the largest and smallest drag. What was amazing about this demonstration was that it was not a straight forward lecture. These professors understood that we aspired to be engineers and that to do that we had to think. They did not tell us the facts, they asked us which object we thought had the least drag and what our reasoning was behind our decision. The professors pushed us to come to conclusions which made us remember what we had learned in the presentation. I greatly appreciated the interest these professors took in us, and I will definitely remember them for the valuable information they have taught me.

RPI Civil Engineering
Posted on 3/08/2012 11:10:00 PM by Shane with No comments
Yesterday on our excursion to R.P.I. we received a demonstration and presentation about the civil engineering program. We were able to see a full scale centrifuge up close, as well as a one tenth scale model. The centrifuge can apply up to ten times the earth's gravitational force on a soil sample to see the stresses and effects of natural disasters such as floods, land slides and earth quakes. We also learned about the connections between R.P.I. and many other universities that share data and experimental tests about earth quakes, tsunamis, and earthquake effects on residential structures. It was great to get to see such amazing technology and learn about the research being done with it.

RPI

Today our InvenTeam traveled to Rensselaer Polytechnic Institute to meet with professors, PhD candidates, college students and members from other InvenTeams and FIRST Robotics teams from all over New York State. We started out with a tour of R.P.I. facilities including their centrifuge which can simulate forces up to one hundred times the earths' gravitational force, and a scaled wind tunnel where we learned about airflow and the effects of surface area on an object in motion. After the tour we made our way to the state of the biotechnology building for a discussion with current R.P.I. students about their experiences at the college and co-op programs. Then Aaron, Liam, and Sam presented to the other InvenTeams and FIRST teams about our progress thus far this year. We were followed by the Berlin team who had a wonderful video describing their project and progress. Their device to help the blind and hearing impaired while being active in sports such as skiing is very impressive! Next we were taken to the auditorium to see the presentation of the Lemelson-MIT awards. Before the ceremony we were able to learn about each finalists work, as well as meet them and ask questions. This was very inspiring for an aspiring engineer to see the work that many would think impossible come to fruition. During the ceremony we engaged in telecommunications with M.I.T. as well as the University of Illinois at Urbana-Champaign for the recognition of finalists and award winners.
The winner of the Lemelson-MIT award at R.P.I for 2012 was Fazel Yavari! His work included the engineering of a small sensor to detect NH3 and NO2 emissions that could be harmful. The sensor uses graphene foam which is essentially a sheet specifically arranged carbon atoms that is thin and ultra sensitive. When in the presence of NH3 the graphene foam changes resistivity alerting observers to the presence of the dangerous gas. The sensor is so sensitive that it can detect .5 parts per million of NH3 and NO2 which is far less than any existing sensor. It is also very cost effective as each 17 X 22 cm sheet of graphene foam can make 400 sensors. This sensor will help protect the environment as well as assist national security forces to detect the deadly substance quickly.
I was stunned by the work of these amazing engineers. They are the next leaders of our world, it was awe inspiring to be in their company and converse with them if just for a few minutes. Hopefully one of our InvenTeam members will be able to change the world as much as these men have, and we will get to see them receive a Lemelson-MIT award. Posted by Emma Rocco

Makerbot Innovation
Posted on 3/06/2012 11:18:00 PM by Shane with No comments
For the past few days I have been working on an Inventor model of a larger scale 3D printer. We have been trying to conjure up an innovative idea on how to re-purpose a 2D plotter into a 3D printer. So far that idea has not taken flight, so I decided to come up with a design. It's very similar to the Makerbot's architecture. Here is what I have so far:

Drip... Drip... Drip...
That is how class began today.
Drip. Drip. Drip. Drip. Drip. Drip.
It was then we realized that the same apparatus that caused the flood originally was leaking again. We grabbed a few garbage cans from adjacent rooms to stop the floor from getting too wet.
SWOOOOOOOOOSSSSHHHHH!!!!
Water started pouring out like a fountain all of the sudden. We all rushed to save computers, electronics, the mill, etc. Hysteria is the only apt word that would describe the mood of the room. Video cameras were taping the monumental event while custodians tried there best to stop the epic leakage. Eventually we were all evacuated to the library.
Everything is fine now.

Technical Troubles with the Mill Technical Troubles with the Mill Technical Troubles with the Mill
Posted on 3/05/2012 10:41:00 PM by Shane with No comments
While the cooling group was milling parts today, we noticed a slight wobble in the mill bit as it spun. This problem could lead to less accurate parts and broken cutting tools, but can be mitigated by milling in very shallow layers. This should not affect the quality of the milled base, but it will slow down progress.

Former student, Isaac Banner stopped by to check in with the InvenTeams progress this year, as well as to visit with Mr. Gallagher. It was great to see him and hear about his experiences at R.I.T. He spoke with us on the value of the Project Lead The Way classes he took in high school, his courses at R.I.T., and his recent innovations. It was inspiring to see another Saratoga student making their dreams come true through hard work. As as class, we hope to inspire all the students that will follow us. We are certainly all proud to be following in the foot steps of our E.D.D. alums. Some alumni are shown below.

Today the InvenTeam had our first, well deserved snow day. Although we were not physically in school the work did not stop. The 3D printing group is working on sketches of possible mechanic schematic designs if we do not decide to use the 2D plotter as a frame.
The 3D printing group also received notice that the new emergency shut off chip has arrived! We will be able to solder the chip in class on Friday and hopefully have the printer fully functioning and printing parts by the time we go to RPI on Wednesday.
