Purpose: The E-Nable Project is a global collective using 3-D printers to provide prosthetics pro bono to those with upper quadrant disabilities. 3-D printing is revolutionizing prosthetics in both function and cost, especially for children and adolescents. A prosthetic arm can cost around 40,000 dollars depending on technology and amount of function. Parents of a child with upper quadrant abnormalities might have to spend this every time their child grows. With 3-D printing all the parents would have to do is send in for a bigger part and add it to their own child’s prosthetic. No added doctors visits. No prescriptions needed. 3-D printing encourages customization making children with disabilities feel less like they are wearing a medical device and more like the E-Nable hand is just an extension of their own body. We often focus on the negatives when it comes to rapid globalization but the E-Nable Project uses the global community as a force for good in a changing, STEM-based world.
Plans: Wildwood and the WISRD Community both hope to stay involved with the E-Nable Project for years to come. We are thrilled that our 3-D printers are able to both teach our students exciting STEM-based advancements and help people globally who are less fortunate than us.
Update- January 24th, 2019
E-NABLE is up and running again! The forum was updated, and is now working smoothly! We reached out to a man in Texas, and he wants our help creating an elbow driven arm. We are talking about measurements and details with him right now, and cannot wait to move forward!
Update- August 22nd, 2018
Welcome back! Over the summer, we have been communicating with many people who would like to be involved in E-Nable. As we are our own chapter now, we can add members to our chapter to collaborate on various projects. We are currently in the process of adding both some assemblers and some designers to our team. As our chapter grows, the more people we can reach to help the community!
Update- May 7th, 2018
I finally fixed the Lulzbot Taz. I ended up not using the star washers because it worked fine without it. So happy it’s up and running again.
Update- May 3rd, 2018
Today we heard from some people who wanted us to print them a hand. We told them to reach us through the e-Nable website.
Update- April 30th, 2018
We had our poster presentation today and talked to Dean Ho about our project. He was very interested in our publicity and asked if we would like to write an article about e-Nable for more publicity. We will continue communicating with him about this.
Update- April 22nd, 2018
I worked on the ceramics printer today again. The clay was molded and smelled really bad, but Joe told us that it was ok to use the molded clay so we inserted it.
Update- April 20th, 2018
Today we reprinted anemometer parts for the Aerodynamics Lab.
Update- April 19th, 2018
We are working on our poster presentation, which is on printing in different materials.
Update-April 16th, 2018
Someone misplaced all the pieces we needed to reassemble, and when we found them, they had been taken out of the cup, and a star washer was lost. Joe ordered a new one. It’s a 4mm exterior star washer to keep the thermistor in place.
Update-April 13th, 2018
A new thermistor was needed, and since the thermistor is attached to the extruder, we got a new extruder too. Emily replaced these while I was sick. I started reassembling everything else.
Update- April 10th, 2018
The makerbot just needed to be cleaned. But now the Lulzbot Taz is broken. The screen on the printer says the heater isn’t responding. We figured out that the thermistor is disconnected. Trying to see if I can connect it again or if a new thermistor is needed.
Update- April 9th, 2018
First day back from break. Came back to a broken makerbot. I’m currently taking it appart and trying to figure the problem out. The printer just stops extruding after a while.
Update- March 16th, 2018
The attempted print with steelFill failed, because the filament is super brittle and snaps throughout the print because the extruder moves. We are trying to figure out a way to keep it from snapping
Update- March 15th, 2018
Today we worked with steelFill. We set the extruder to 230°, and the bed to 60°.
Update- March 7th, 2018
We attempted to print in bronze today on the Lulzbot Taz. There was some wood filament stuck in the nozzle that caused half of the print to be in wood, so we cleared it out*. We then changed the heat settings to 210° on the extruder and 60° on the platform. We are currently polishing the bronze print.
*note: if you change the filament, run a random print first with the new filament in so extrude any filament left over from earlier.
Update- March 5th, 2018
Emily and I printed with a new software, using the Kinect software from Xbox, through a program called Skanect. The program scanned my face and made it into a 3d print file. We then printed it! Something to keep in mind if this is done again is to make sure that your hair is out of your face, as it can interfere with the scan, and to move slowly, but not too slowly.
Update- March 1st, 2018
Today I helped Emily and Luke with the ceramics printer, and it successfully made a new print! Love watching the printer run because it has a completely different way of running than the normal 3d printers.
Update- February 28, 2018
Today we got the Credly badge!! We now filled out the google docs form to become a real chapter! It says it will take about 1-2 weeks and then we will be on the chapters map.
Update- January 16, 2018
E-nable has replied to our forums page!! We are beyond satisfied. We are still waiting approval for our badge though, which is the ticket to becoming an approved chapter.
Update- January 6, 2018
We looked at the credly badge we plan on claiming, and it wants evidence attached in order for us to claim it. Here’s the link to the badge. We posted a video we made of the hand and attached it to the forum. Here’s the link to our post.
Update- January 3, 2018
As we start 2018, we have made some goals. The first one is to get approved in January, so we can start the year off making hands. The second one is to make at least 3 different types of hands in 2018. And our third one is to focus on the hands this year and try to keep the 3D printers up to date and maintained so we don’t end up having to focus on fixing them.
Update- December 14, 2017
Today is our last class of 2018. We leave e-Nable with a plan for next year. We started filling out the form, and the only space we have left to fill out is our credly badge, which is a badge that gives us approval for becoming a chapter. We will continue this in 2018.
Update- December 11, 2017
We just found a website where we can request to join the chapters map. We plan on filling this out next class. Heres the link to it: here
Update- December 4, 2017
A new narrative and reflection process has been presented in the institute, and there has been much success under these new standards. After writing reflections, we have continued to work on the long application process. We’ve filled out all the forms we can, created a youtube and our introduction video, been very active on twitter, joined the e-NABLE Google+ community under our new email, and completed a different form of request for becoming a chapter. We have also been in direct contact with members of e-NABLE, and they are following us on our Facebook page. Since our video is up, it is now pending approval again!
Update- November 28, 2017
The hand is completed! We are sending it in to get verified so that we can start our own printing center.
Update-September 30, 2017
We ended up using 4×40 bolts too. This worked super well. We are now focusing on fixing a printer that has been clogged.
Update- September 20, 2017
We are almost done with the hand!! We are trying to screw on the velcro, but can’t figure out what bolts to use. We know that the nuts are 4 40.
Update- September 13, 2017
We fixed the screws, but now something is wrong with the finger joints. When we bend the fingers down, they don’t snap back up. We are trying to figure out why this happens, and we think its either that the elastic is too loose or that the finger pins are too tight.
We figured out that the reason it did this was that one part of the finger was too thick and created friction between the other part. We fixed this. IMG_4640 2 As you can see in the video, the ring finger is still incorrect while the rest snap back into place.
Update- September 11, 2017
The screws that connect the string from the palm to the forearm were put in incorrectly. They were put in so that the holes faced each other, instead of facing out. We are currently fixing them by rescrewing the bolts.
The top one is screwed in the correct way, while the rest are not.
Update- September 7, 2017
The piece that we are currently working on should end up holding a screw based on the original plans. However, the screws are cracking our pieces, and bolts have proven to be very stable and more accountable. We are creating threads so that we can twist the bolt into place without any cracks.
Update- September 6, 2017
After reprinting the hand, we decided to stretch the holes using a screwdriver. We connected the forearm to the palm successfully, and are now working on attaching the flexsors to the forearm.
Update- August 31, 2017
Today we were assembling the hand, and the holes in the side of the hand were too small for the pins, so when placing the pins in the hole, the forearm snapped and we are currently reprinting it.
Update- August 30, 2017
The wrist portion of the hand just finished printing. Next it will be assembled to the palm and the flexsors will be threaded through the wrist, and then it will be complete!
Update- August 21, 2017
The e-nable team is back and working again!! We have a new member working with us, Emily R. We plan on sending in our test hand and getting approved so we can make a chapter as soon as possible.
Update – May 23, 2017
We are assembling the hand. We have all of the fingers put together and have the thumb attached to the palm.
Update – May 19, 2017
All is printed! We are currently assembling the second and final test hand.
Update – May 16, 2017
We are currently printing the last piece of the hand—the palm. Then we will assemble. We are also working on fixing one of the other printers that broke. It is almost done.
Update- April 14, 2017
The Makerbot printer that we have been working on for a while has finally been completely fixed! We had to completely take the printer apart, replace the wires, and then reassemble everything. It has successfully test printed a bracelet. We also have 95% printed the hand! Here is a picture of the hand and the fixed printer
The only thing left to do is figure out how to tie the strings in a way that will make the hand sturdy but adjustable.
Update- April 12th, 2017
The hand is so close to being done!!! The printer is also fixed!!! All printers are back up and running!
March 29, 2017
We have finally printed the finger joints! Now all we have to do is assemble the strings. We have now used 3 3D printers for this hand: Makerbot for the fingers and forearm, Ultimaker for the palm and Lulzbot for the finger joints.
Update- March 24th, 2017
Everyone is back to working on the MakerBot. The motor just won’t click back into place. Might need to contact support.
Update- March 17th, 2017
The Lulzbot Taz is fixed. We needed to take apart the entire printer in order to loosen the grip on the clogged filament. It is up and running!
Update- March 4th, 2017
The Lulzbot taz is clogged. No directions on how to fix so I (Lea) took apart the nozzle. Working on fixing it. Can’t seem to figure out how to unclog.
Update- February 20th, 2017
The MakerBot is being fixed. We order a bunch of new pieces for the printer. Coming along well.
Update – February 6th, 2017
Fixed hand print by raising palm several mm’s and changing extruder #2 from dissolvable to ABS. This caused the first layer to be printed as dissolvable filament and the filament stuck to the platform. with the other setting, the dissolvable was printed on top of the ABS filament and it did not stick to it at all. (Joe)
Update – February 3ed, 2017
We finally fixed one of the printers completely. Now it is up to date and connected to the computer. It is currently printing the palm for the hand.
Update- February 1st, 2017
We got a replacement for the fried 3d printer… but only one of the parts we need. We also need the male connector that was fried. Joe is going to buy one later today.
Update- January 26th, 2017
Today we remodeled the lab! The 3d printers are now placed more practically. Easier to get to.
Update- January 12th, 2017
A few unfortunate things happened today… We ran out out of dissolvable, but more is on the way. The palm of our blue K1 hand also broke! As we were trying to reprint the palm, a wire in the wire encasement fried.
We are not completely sure what wire this is, or why it happened. We will keep you updated.
Update- January 11th, 2017
We just recently, we found a letter written from a former student, concerning e-nable. One of the hands printed last year was sent in, but sent back because of a problem. The problem had something to do with the wrist. We are not completely sure what the problem was, but we are working on figuring it out. We will then have to do some paperwork and send it back in. We have contacted the former student and asked how to get the paperwork and what was wrong with the hand. We have not gotten a response, yet.
Update- January 4th, 2017
We are coming back from winter break we have made great progress. The hand is 80% done. The only thing left to do is assemble the thumb. We also learned that the strings running from the tip of the fingers to the wrist are supposed to be tied back to the space between the palm and the wrist.
Update- December 6, 2016
We have assembled certain pieces of the hand, but not all. While I was assembling the thumb, it broke so it is currently re-printing. Once the thumb is done we can finish assembling the hand. Here is a picture of the hand so far:
(The thumb is being printed and the pinkie is still soaking in limonene to get the dissolvable filament off).
Update- December 5th, 2016
The right fan in the Makerbot Replicator 2x was replaced. It is functioning very well so far. Here’s how we did it:
Update- November 30th, 2016
We just got some flexible filament that we are excited to experiment with. It is currently in the Ultimate printer.
Update- November 20th, 2016
The hand is completely printed. We ended up not doing the acetone bath, because the fingers broke every time we gave them one, and we couldn’t just do the palm and forearm, because it would look weird.
Update- November 16th, 2016
All items have been printed, but the pinky. We have also tried the acetone bath. Here are the steps to completing a successful acetone bath:
Materials needed: your 3d print, acetone, a cloth, a small stove, beaker, string, something to attach the string to.
Cautions: DO NOT GET IN YOUR EYES OR MOUTH, wear goggles, try not to touch the acetone at all, make sure the string is strong enough to hold your print in the beaker, don’t let it be in the acetone vapor for too long because your print will melt.
Update- November 14th, 2016
Today we had a poster presentation here at Wildwood. It went very well. Grace Kaz and I made a poster to present, which turned out very well. Visit the WISRD lab to take a look. During the presentation, we had the fingers reprint.
Update – November 9th, 2016
We have just printed the thumb. Once this is done, all we will have to do is reprint two of the fingers that did not turn out well. Then we will do the acetone bath. Lastly, we will assemble the pieces together. Here is a picture of everything that we have right now, excluding the thumb since it is currently printing. We have the palm, the forearm, 1 of 3 fingers, a pinkie and lots of joints. We printed more than enough joints just because they were easy and if we need them in the future we will have plenty. Once we do the acetone bath, they will all be shiny and smoother.
Update – November 3rd, 2016
We realized something weird with our prints. The palm and forearm get rough where the dissolvable filament was surrounding it. Here’s how we printed it: On makerbot, with a dissolvable filament box around the base of the print so that the print doesn’t get rough lines from the support and raft(which it ended up getting anyways), dissolvable filament from the left extruder, and ABS from the right, and with both extruders at 230 degrees. Unfortunately, we didn’t think to record the rest of the settings for the print, because we didn’t think we would be having this problem. After printing, we put the print in Limonene, so that the dissolvable around the actual print would dissolve. We are currently looking at the problem and what could have caused it. We will reprint it with these new settings:
Update – November 2nd, 2016
We are currently printing the joints for the hand. We are also preparing our poster and researching about flexible filament. We are thinking about using this for the fingers of the hand. This is a filament that is strong and durable, yet stretches easily and is very flexible.
Update- October 23rd, 2016
We have made a Facebook page for E-Nable. We are currently also making a donation page, and we are working on making a Trello Page.
Update- October 10th, 2016
We have now printed the forearm for the hand we are currently making. I will soon be printing the fingers.
Update – October 5, 2016
We are currently printing the forearm in the same material on the Ultimaker. Here is the forearm printing:
Update – September 21, 2016
This year we have so far started a Facebook page about our school chapter and have been emailing with the E-nable community. We have also been working on a test hand. We started with printing the palm. The first time we printed the palm, it didn’t work out because certain parts of it were so delicate that we broke them off unawarely. Then, we accidentally printed it in the wrong material (dissolvable filament). Finally, we printed it right and are now working on printing the forearm.
This is the forearm in the process of being printed:
