Assessment 5 - Natural forms

A box was made in grasshopper and populated with 3D points 

3D Voronoi was used to create blocks within the box 




An attractor (NURB) was added so that all blocks points within a certain number (on the slider) would remain and the rest can be hidden

The formation of the blocks can be changed by adjusting the number slider 
Once I was satisfied with the form I added a mesh to the form using the Weavebird plugin, which has the ability to thicken the mesh

Final iteration of 3D model 


Unfortunately this model is very hard to 3D print, so I decided to print the base form instead and forego the meshes in my real life model.




Rough print of model.
In my first prototype I attempted to print with the mesh pattern on the outside but it did not turn out well. 



For my final model I decided to forego the mesh patterning outside and just print the form instead. 
Prototype of model once the mesh was removed.






Half of final model (below). The model needed to be split in half in order to fit in the machine (in order to meet the assessment 5 dimensions). 
The print was not successful because the machine jammed when the print was up to 60%. 
For my final model I decided to forego the mesh patterning outside and just print the form instead.

Assessment 4 - Joining structure

I created a dodecahedron in grassshopper with the Lunchbox plugin

I separated the faces and edges so that I could work on one face and apply the same step to the other faces

 Planes were created on every face



One face was extruded and the edges were divided into 5 segments so that the slots can be made



Rectangular blocks were swept along the edges to create the slots and then were trimmed out from the extruded face 


The faces were then oriented and exported for laser cutting 





The first attempt at laser cutting the model (below). 
Problem encountered: Even though I took the material thickness into account, I didn't think about the angles required for the assembly of the dodecahedron, therefore the slot sizes need to be adjusted. 





The final product.
The slot sizes were adjusted and fit together perfectly so that glue was not required.
