Being at the PCMI gave me the opportunity to work with and learn how to use a 3D printer. Moreover, we had some great workshops where we also learnt how to design using Rhinoceros 5 (unfortunately we just got the 90 days free trial and I am quite sad about it. Does anyone know about another similar software that is cheaper or even free online? I would appreciate your help a lot). So, using these things I decided to design and print something. Thus, I will give a little inside into my project. Also one of the other participants accepted to share her project, too. Let’s get started:

1. Bear project (this is my project): I wanted to do the heads of Mini and Mickey, but it seems I wanted to much (maybe next time) and instead I opted for some (easier) bear heads (nothing to fancy). I used one big sphere for the shape of the head and 2 smaller ones for the ears ( just made one and used copy and mirror for the 2nd one). Using Boolean Union I glued the 3 spheres together. And one head is finished. For the 2nd one I mirrored and copied the 1st one, but I wanted to add something cute to this new one. So I decided to make a hat: one thin ellipsoid (rotated approx 20 degrees, so that it looked a little tilted) and a cylinder (again rotated with the same degrees) positioned in the middle of the ellipsoid. The last step was to glue everything together with Boolean Union and the 2nd head is finished.

Here are some images from the printing process (I was fascinated by how it made the spheres using hexagons for filling them):

2. Snowflake project: this seems to be more work than mine and it has more details. She used boxes with different sizes for the base: the small boxes are rotated with 315 degrees (on the horizontal), she mirrored them and then union with the bigger box. So one arm finished, she just had to copy and rotate it 60 and 120 degrees. After this, she thought that it doesn’t look extremely nice and decided to use some spheres for a nicer visual effect. She used some spheres with different radius positioned in different places (again she did it for one arm and copy and rotate for the others), union of everything and the snowflake is ready.

Here are some images from the printing process (she had some problems with the white filament for the printer and redid the project with transparent filament; also you can observe that the printer made quite of a base for it, which she had to peel off):

Hope you enjoyed this post with our small projects. If you have any questions about them comment bellow. Also I want to say thank you to Anja for accepting to share her project and design. Thank you!

As you can see this idea gave me a lot to think about. What do you think? Should everyone have a degree in math? Hope you are all having fun this summer, don’t forget to check my Facebook event: Mathematics and Summer ^_^ Thank you for your help and support. Thank you for reading. You can find me on FacebookTumblr, Google+,  TwitterInstagram and Lettrs, I will try to post there as often as possible. Don’t forget that maths is everywhere! Enjoy!
