### Bird Fractal

November 9, 2017

I named my fractal the bird Fractal because I think the removed squares resemble little tiny bird. To create this , I removed (0,0), (1,1), (3,1), (1,3), and (3,3). The surface area for level one is 11 because we started out with 16 pieces total, and I removed 5 pieces. The area for level two […]

### Hinged Dissections

October 5, 2017

For our project we will be exploring the rhombic dodecahedron which is a 3D shape that is made when you turn a 3D cube inside out.  Our method for printing this will be printing out 6 pyramids of the same dimension and taping them together so that we can form both […]

### Prince Rupert’s Cube

October 5, 2017

Our project idea is to make a Prince Rupert’s Cube. The Prince Rupert problem was proposed by Prince Rupert of the Rhine, Prince Rupert’s cube is the largest cube that can pass through a hole cut through another cube without splitting the cube into two pieces. This proposition was […]

### Thurs Oct 5 – Begin Open Projects

October 5, 2017

Not much to say today except “let’s go!” Ground rules for the Open Projects Your goal is to find something to design and 3D print, and then talk about the math related to that object. You must design the object from scratch in Tinkercad or […]

### Mathematically Fair Cake Cutting

October 5, 2017

My group members and I originally wanted to look into Chapter 4 of Things to Make and Do in the Fourth Dimension by: Matt Parker. However, we decided to switch and do our project on cutting a cube to be equal in volume no matter how many slices it is cut into. If 5 people […]

### Rhombicuboctahedron

October 4, 2017

The chapter we chose for our project was chapter 9, which is all about graphs. For our project, we chose to do a 3D print of a Rhombicuboctahedron. We believed it would be easy to print because it is made up of triangles and squares. We would like to learn coding to make a wire frame […]

### Borromean rings

October 3, 2017

Our project idea is to create a print of elliptical Borromean rings from chapter 8 of our book. Borromean rings often contain three rings, but can contain up to four or five. We are going to start out with a three ring print because it is the most simple way to make Borromean rings, then […]

### Meissner Tetrahedron

October 3, 2017

Our initial project idea is to create a Meissner tetrahedron. It involves taking a regular triangular tetrahedron, but then rounding all the parts to a precise point creates the Meissner Tetrahedron. What is really cool about this is that, although it is not like a circle containing zero edges […]

### Trefoil Knots

October 3, 2017

Our group will be making the Trefoil Knot which is one of the prime knots based on chapter 8 of Things to Make And Do In The Fourth Dimension. We were very interested in this particular knot because it looks different with each kind of projection and there are many ways that we can […]

### Tues Oct 3 – Open Project Pitches

October 3, 2017

For the last week you’ve been thinking about what you might want to investigate from the Things to Make and Do in the Fourth Dimension book. Time for pitches and forming groups! // Ground rules // You must have different group members than last time […]

### The Pizza Problem

October 3, 2017

For our open project idea, we decided to experiment with the relationships of the “perfect pizza slice” with its self and with the pizza as a whole as a solution to the pizza problem. The goal of the pizza problem is to find how to cut a pizza into same shaped slices that don’t all touch the middle […]

### Thurs Sept 28 – More Math, More Presentations

September 28, 2017

### Pyramid Spiral Fractal

September 19, 2017

For our first fractal we wanted to start with the shape of a pyramid. The first pyramid is 30x30x30. To start we shift a copy of the pyramid up by 2. From there all of the dimensions are decreased by 2 mm and tilted by 22.5 […]

### Tues Sept 19 – Iterate, Calculate

September 19, 2017

// Roundup // According to the Assignments page, by today’s class you should have fixed any issues with your Tinkercad Fractal blog post, and added a new section documenting your first draft 3D print. // Today in class // If you have prints to send […]

### Firework Fractal

September 14, 2017

For our first design, we wanted to go with something that was simple to create but flexible to expand on. As of now, our design is made up of different sized shape of gears. We started off with the center gear being 60×60 and then […]

### Tax Evasion Cube Spiral

September 14, 2017

Originally, we were thinking about doing a chain fractal based off of doughnut-shaped tubes, but we got inspired by the spiral cube fractal made in class. So once we had found a preset object that included a literal ring of cubes […]

### Whirly Cross Fractal

September 14, 2017

The repetition is by half the dimensions of the previous base. (Ex: Base 3 is half the length, width, and height of Base 2). Each increased base is then halted and so on. This makes it a fractal because it is a duplicate and a scaled […]

### Thurs Sept 14 – Is it fractal?

September 14, 2017

Today we’ll continue with the Tinkercad Fractals project, and iterate on your first draft designs. If your designs are well-defined fractals then you’ll print them in class; if not then you’ll redo them and print after class. Discuss the following with your group members: Is […]

### Super Mickey Fractal

September 13, 2017

For our first design, our group wanted to do something simple but interesting. At first, we weren’t sure what to create so we got some inspiration by looking up some random and funny things on google. We ended up finding an image that had a bunch of smiley faces which […]

### Mandala Fractal

September 13, 2017

For our very first design, we were inspired by some mandala pictures that we found, and they resembled fractals because a mandala is just several levels of rings with different self-similar designs in each ring. We wanted to construct it in a way that it would look original […]

### Sunflower Fractal

September 13, 2017

After studying fractals in class for the past few weeks, our group decided to try to make our own. In making our fractal we decided to go for a sunflower type shape with a hollow center, where the image repeats by halving its size […]

### Fruit Loops Fractal

September 13, 2017

We created a circular fractal for this assignment. None of us had ever seen anything like this, so we thought it would be perfect to experiment with and present to the class. This design is a fractal because it is simply a repeating […]

### Tues Sept 12 – Tinkercad Fractals

September 12, 2017

// Roundup // According to the Assignments page, by this morning you should have read the first part of the Fractals book and added a section to your First Fractals blog post about your printed fractal. The few of you who have not yet printed […]

September 12, 2017

We decided to make a simple Minecraft Creeper fractal for the purposes of this example post, but you should try to think outside the box and consider many different ways of generating a fractal to come up with your own unique design. Your assignment is to create a new fractal […]

### Thurs Sept 7 – Still Printing Fractals

September 7, 2017

Today in class we’ll continue where we left off on Tuesday, which means that we’ll be 3D printing the remaining First Fractals and discussing the corresponding blog post writeups. Maybe if we have time we’ll watch this video to get a quick overview of how the […]

### Koch Snowflake

September 6, 2017

The first fractal I want to print is the Koch Snowflake. According to Wikipedia, the Koch Snowflake is a mathematical curve and one of the earliest fractal curves to have been described. It is based on the Koch Curve which appeared in a 1904 paper titled […]

### Sierpinski Carpet

September 5, 2017

For my first fractal, I would love to try printing a Sierpinski Carpet. Not only am I beginner on the front of 3D printing, but I am also very fascinated by minimalist design. Illustrative Mathematics states that this is a fractal whose area is zero, […]
