Waffle Design: Assignment 3

My process.

1) Firstly I started with my parameters. 

2) Next step was to construct my shape keeping in mind and making reference too these parameters as a key. 

3) I created my overall shape using a polygon series that rotated as it changed the incrementation of the shape continued along the series. 

4) I then created an identical tower, however offsetting and some of the parameters so that the tower passed straight throught the original object in the z direct but left space from the original bounding edge of the original object. 

5) I then solid differences the two shapes which resulted with the above left image. This became the foundation for my waffling script. 

6) To create the the sections, I constructed a series of boxes that intersected my objects at the desired angles. These thickness of these boxes would represent the thickness of my material that i would use for printing.

Creating Slots for material connectioning

7) Result in z direction after the two x and y direction sectioning had been solid differences from one another interchangeably. 

8) For the tagging I thought about using a single lined font plugin 

download from the grasshopper forum called 'Bowerbird' to save time printing and also lessen the aesthetic effects of the tag on the printed object. This prooved very useful 

Resulting printable layouts. 

Old Original Design - now obsolescent 

Originally I used Rhino to create this form. 

This was out of response to the following issues. 

Explanation: 

I encountered a number of difficulties with this design to which I worked out in the above process. These include:

1) sectioing in rhino

Reasoning: Section in rhino may be a quicker alternative to working with grasshopper, however, the adjustability of the parameters et( for example the thickness of materials) makes it hard to change in permanent softwares like rhino. 

2) creating a form

Reasoning: I found it initially to create a form of interest using rhino and chnaging the parameters or the design would be quite difficult. 

Old design are as follows: 

 

My Waffle Design mainly comprises of a series

I did however create the initial curve within grasshopper and the script below comprises of a series of points which would then were interpolated into a curved line. A series of these curves were constructed in thsi way which in turn, where lofted to create my curve. this curve was extruded into a solid object.

Whilst printing my waffle design, I realized I had set the wrong thickness for my contours and so the section cuts between each piece was too small to fit together. I will have to remodel my design and repeat this process.

Assignment 2: The attractor Submission

The Process

1) First I created a set of points that ould direct an over all arc to my object. 

2) These points were arced and an inner arc was created for the adjoining lines vectors. 

3) A series of lines were created that fed form one arc to the corresponding series item within the other.

4) This result was piped. 

3d Printing 

New Printed Version of Attractor Design

 I started encountering problems with the Maker bot during the second half of printing my design.
 I believe that when I had sliced the two half to separate them from one another, I may have sliced horizontally as well, and slightly offset the cut pieces which has resulted in the Maker bot skipping layers when printing.

 1/2 pieces that I will use for submission, however certain pieces need to by glued back together.

This script was developed in order to over come some of the floors in the previous 'Attractor Design'

 Printed Result using Blue Filament within the MakerBot.

Wasn't as successful as I would have hoped. Further Model developing and refining needed.

Alternating My design

I encountered a number of problems when I showed my tutor my previous model saying that the model was too "stringy' and 'dramatic'. This would cause trouble for the extruder during my model creation and from her experience, would fail during the process. I sort to fix this problem by changing the rotational angle and the thickness of the 'tube' polygons by changing the radius. I created a more organic shape and found that this was more suitable for 3d printing.
