Week 2: Getting familiar with printing structures

32Oscillating circle pattern in Netfabb and 3D printed.

This week we received the first two printed models, one is an oscillating circle reaction over time. We were expecting a pattern of many stacked hollow cones but this is not really visible in the print. When we worked on the model in Rhino we scaled it in the z direction to make the cones bigger but it actually made the pattern messy and ruined the details. Next time we’ll skip this step and get more detail by letting the reaction run for a longer time. Furthermore this model is not good enough for testing but it showed us the do’s and don’ts when using the Connex3 printer.


Reaction diffusion pattern in Rhino and 3D printed.

The second model is the diffusion of a single substance over time. This pattern is really promising because the 3D structure consists of a single surface with shapes like tubes, holes and funnels.

Last week we did some individual research and today we put all the information together during a brainstorm session. Some of the questions we asked ourselves:

  • What properties can patterns have?
  • Which shapes can be created by the Belousov-Zhabotinsky reaction besides spirals, circles, trees and waves?
  • How can we use the regularity of certain patterns?
  • How can we use the self organizing nature of reactions?
  • Can patterns maximize the contact surface?
  • Can a pattern hold information?
  • Can we interact with the pattern formation during printing?
  • Can patterns minimize material use but give maximum strength?
  • What is the advantage of visualizing the passage of time as a dimension?

We want to create something valuable and tangible with this project so we decided to apply the Belousov-Zhabotinksy pattern in a product.To get a better grip on how we can do this, we are going research the relationship between patterns, pressure and shock resistance.
