The second full week in the OEDK was spent learning 3D design software and building Printrbot 3D printers.

The first few days were spent mastering CAD (computer aided design) programs such as Tinkercad, IronCAD, and during down time, SolidWorks.  Files from these programs were converted and transferred to one of the OEDK’s large 3D printers, and each intern was able to print something small of their own design (mine was a cylindrical piece with columns, below).

The rest of the week was spent assembling 3D printers in teams of two. Florence and I assembled one together, and took pictures of the process.  Below, in order, are photos of all the pieces used in the build, a close up of the assembled hot end, fan, sensor, and extruder motor with attached wiring, and a shot of the finished wire organization on the underside interior of the printer.

  

 

We began printing files from Thingiverse, an online resource of 3D printable files. Most significantly, Florence and I were able to print a small box with an interlocking lid (below).

 

I’m very excited to begin working on our projects this coming week! With the skills we have learned thus far, it should be a productive summer.
