The Research

What is the influence of cell structures towards the bending behavior of the TPE?

The Research method:

1. Choosing one fragment of our furniture

2. Requirements of that one fragment

3. Cell structures research (causing it to be soft, hard, stif, flexible, strong or weak etc.)

4. 3D printing the above cell structures

5. Testing and evaluating the cell structures

6. Conclusion for the choice of structure.

Translation to Grasshopper

Now it was our task to think of selecting certain structures, and translating them in a three-dimensional way. What should be mentioned i that there can be made many more interesting structures, but for now we've made a selection of three different strategies of structures that result in a different bending behaviour. The translation into Grasshopper has been a very helpfull excersice for us, it made us understand the logic of Grasshopper better. We can use this knowledge and skills to make even better structures in a later research, for now; let's focus on our three selections.

3D-Prints

.1 TPE 45D Experiment: Semi-Flexible TPE, Wireframe structure

It was right after our first wireframe experiment that we've noticed semi-flexible TPE (flexibility 45D) is way too strong for what we want to achieve. It is not (only) a matter of structure with this semi-flexible TPE, but material characteristics seemed to be of way more importance. This print recieves its flexibility through (accidental) mistakes which occured during the printing test: certain horizontal wires are not printed which make the structure actually bend in quite well, while remaining (almost) completely stiff by itself. Problematic can be the structural deformation on a bigger scale.

.2: TPE 85A Experiment: Flexible TPE, Spongeous structure

A flexibility value of 85A felt directly much softer. Sitting on this piece of 10x10x5 cm already felt comfortable while the structure is deforming slightly. A great value of this spongeous structure is that the printer can always print these spheres on top of eachother. This avoids toolpath manipulation that occured during the Voronoi test print.

.3: TPE 85A Experiment: Flexible TPE, Voronoi structure

The Voronoi structure was much harder than we expected it to be. Putting pressure on top of the structure barely shows any deformation, and feels not nearly as soft as the sponges structure we've printed earlier. Although putting the structure on the side allows the bigger Voronoi cells to buckle a lot, resulting in softness, although this softness is not as comfortable as we can achieve with the Spongeous print. In contrary to the Spongeous structure, this Voronoi structure requires less material, at the cost of comfort. The dense area of the structure proved to be very capable for dealing with load bearing parts, even with a flexibility property of 85A.
