Niara-Grip#2 Update 10/28/15

Yesterday, I attempted to print one of my designs on the Afinia. It failed midway during the print. However, Sam got the Luzibot running and successfully printed it. This week, we may print one more grip and I will add some more Interview questions on our google drive for our upcoming physical therapy visit. Otherwise, we are focusing on our other academic responsibilities for the remainder of the week.

Here is the grip below that was printed on the Luzibot



Niara-Meeting Minutes 10/27

Last week, Sam and I were able to print two grips that we plan on bringing to the clinicians. We printed one on the Afinia and the other on the Luzibot. They came out really well without any issues. The only changes made to the Afinia was the nozzle height  (which we changed to129) . This week, we are printing more grips to bring to the clinicians.

Here we have the failed prints that we used to design our box of grips in the PadLab.


Here are two of the grips that we printed last week for the crutches.

Sam-Weekly Update

This past week was very productive in terms of generating new grip prototypes. After finally getting our printers to work properly, we were able to design and print to new grips to test with the clinicians. These prototypes are meant to be nothing more than creativity boosters and examples for the clinicians to use when thinking about designing their own grips. With the printers now regularly working, we should be increasing are productivity time in producing grip design and prototypes.

Last week I also started to learn how to use Memento, a new software by autodesk which allows 3D models to be creative with a set of images. Do a few test trials, I have found the software to be very useful as any of our 3D scanners. It does a good job capturing an image and converting it into a 3Dmodel while still maintaining much of it’s physical details.  Here is an example of a 3D model of The Voyager Spaceship model in our lab. With only 10 or so photos it was able to capture the model and all it’s details with 70% accuracy. It has some holes, but will hopefully be improved with better quality photos and an increased quantity of photos.


These past few months, are main conflict has been getting the 3D printers to print without issues. This has slowed us down quite a bit, especially when having to start and re-start printing of grips. The average grip takes 2-3 hours to print. If the printer decides to stop working halfway through, then the process must be done all over again. This is something that we should not only take into account for our own scheduling, but also for clinicians which may potentially have the same problems in the future when 3D printing with our software. We will investigate this further in the future.

Niara-Meeting Minutes 10/20/15 and Todays Events 10/22

On 10/20, we had a meeting just to share our progress from the previous week. Sam and I are 3D printing and modeling this week.

Todays Events

The Afinia 3D printer and the Luzibot have proven to be the most reliable printers so far for printing the grips. I also worked on fixing the holes in the 3D model that was produced using the 3D scanner. I am working on making it look better so that it can be sent for a print. Mostly, the main issues these past two weeks have been 3D printer issues.

Sam-Update: Grace Hopper

This past week, I attended the Grace Hopper Conference in Houston Texas. It was a great opportunity to meet other women in computer science and listen to talks about graduate schools applications and survival. I was also able to attend the CRA-W DREU and CREU breakfast which was a great opportunity to hear from DREU students and their summer experiences at different colleges. This week, I hope to catch up on my Grip Fab work. The first task on my list is to update the 3D scanning software for better scan qualities. This way we can start adding 3D models of potential grips to our repository and start printing grips for testing. We are also waiting to here back from a clinician at UMD in order to meet with her and discuss more potential grip designs.

Niara-Scanner Trouble & Progress 10/14/15!!

Today, I scanned the moldings using the 3D scanner. Unfortunately,the pictures were coming out incomplete. I am going to look up how to clean up the scanned images to fill in the missing gaps of the model image. Once I figure out how to do that, I am going to print it. I also plan on scanning another mold I made today that provides wrist support primarily by the medial nerve. That will also be scanned once more tomorrow and converted into a printable model.
