3D Printing : Fall 2016 Recap

This semester our 3D printers were running daily to produce projects for a few different courses. The largest project came out of the Introduction to Sculpture course taught by Professor Amy Boone-McCreesh. The students were tasked with designing a file that had two simple requirements. It had to incorporate both a hook and a hole. This would allow the prints to connect to one another in countless ways much like the old barrel full of monkeys chains.

Professor Boone-McCreesh prototyped her own example file (see orange and clear prints below) to give her students an idea of where to start.  Brenda Landis then led one training session where the students were taught to use the online 3D modeling program, Tinkercad. They worked for about an hour prototyping and modifying their designs and sent the files over for test prints within 2 days. There were 6 students in the course and out of the initial test run 3 came out ready for more duplication, 1 needed minor tweaking and 2 needed extensive modification. After just a few days the files were able to be stabilized for mass production. The project goal was to print 20 copies of each file for an installation in the Writing Center (you can go check out the installation for yourself!).

The files were small enough to fit between 7 and 15 prints on the bed each time so after a week of printing daily, we had enough for the install. After reflecting on the experience we realized that some files ended up being larger than others but that also made them more stable and less likely to break when they were dropped so possibly increasing the scale would help with long term stability of the files.  The final installation files were printed in clear filament which was a help because the files could easily be repaired with hot glue that blended with the material perfectly so imperfections were not very noticeable.


More requests for prints came in as the semester progressed including a few from Professor Marcus Key’s Natural History Mosaic students. A (glow in the dark!) dinosaur skull and trilobite were printed off of files available on Thingiverse.

A student in an Environmental Studies course came to us late in the semester and wanted to print this mountain terrain for use in a presentation.

Professor Hans Pfister in Physics toured the Makery earlier this semester and was eager to chat to about the uses our 3D printer might provide in his work.  He recently read about the work Math Professor, Dave Richeson, has done on creating impossible cylinders. They are based on Sugihara’s Circle/Square Optical Illusion that is a 3-dimensional shape that looks like a circular cylinder but in a mirror looks like a square cylinder. Professor Pfister wondered if we could print a prototype from Professor Richeson’s work and in just a day Professor Richeson sent over an exported file and we printed a copy for both of them. We love it when a plan comes together.

You can download your own copy of the file on Thingiverse and this is the description of the file with blog posts and journal articles written by Professor Richeson included.

This is a 3D file based on Sugihara’s Circle/Square Optical Illusion. Kokichi Sugihara created the video “Ambiguous Optical Illusion: Rectangles and Circles.”

In it he shows a 3-dimensional shape that looks like a circular cylinder but in a mirror looks like a square cylinder.
The 3D file was created by Mathematics Professor, Dave Richeson, at Dickinson College. He has blogged about the project and has shared a pdf file that can be printed and cut to replicate the illusion. He also wrote an article about the illusion in the September 2016 issue of the journal Math Horizons. http://users.dickinson.edu/~richesod/RichesonImpossibleCylinder.pdf

Halloween Costume Creation Workshop in the Makery

 

The Media Center Makery wants to help you get ready for Halloween. Come out to our workshop so we can help you create your Halloween Costume and props. We have a sewing machine, material, hot glues guns and other crafting supplies to get your started. If you have specific supplies needed, bring them along and our student assistants will help you with your creation. The Makery is open year round as a space for sewing and crafting (as well as 3d printing and programming) so drop in to continue working on your project during our open hours.

If you are looking for cheap material and other sewing/knitting supplies, check out the Carlisle Salvation Army Material Sale Friday October 9th and Saturday October 10th.

Farm Frolics and Student Activities

We had a fantastic time Farm Frolics at the Dickinson College Farm this weekend. Our MC Assistants, Greg, Edwin and Devlynn taught students how to make tiny, vibrating robots out of toothbrushes, paper flash lights, created a solar powered spin art machine using snap circuits, old CDs and colored sharpies. Thanks for getting us out of the basement and letting us play under the lovely sun on the farm. Our staff and creations are showcased well in this video!

And on Sunday Sai and Bedurdin showed off our VHS foosball table at student activities night.

Podcast Nooks Remodeled!

 

       Over the course of alumni weekend, the media center has remodeled the podcast nooks with new desks from Ikea, bringing a new look, along with a brand new recording set-up. Each podcast nook is equipped with new speakers, bass traps, and condenser mics. They also each have new guitar stands for anyone who brings in a guitar to play in the nooks. This new set-up will optimize the recording experience with easy-to-use speakers that allow you to not only control the output volume, but also control the input volume of any mic connected to them. They also have dials that can control the bass and treble in any sound that’s being listened to or recorded. There are also adjustable arms for the mics,which record in stereo. The new bass traps will help absorb excess sound which provides for higher sound quality. The rooms are perfect for working on group or individual projects that require higher sound quality and minimal interference.
