In setting parameters for 3D printing, the team used the Silkworm plug-in for Grasshopper to customize the G Code-thus establishing control not only over the nozzle, but also the printing pattern. Six 3D printed bilayer composite samples of PLA with varying tool path geometry and their response to being immersed in hot water. With customized settings, the team was able to study the behavior of the material, along with comparing notes to previous 4D experiments using wood. The materials are a 3D printed, wood-based, bio-composite. Their question, and mission, became not only how to harness such capabilities, but also how to control them as they formed a unique ‘hydroactive architectural skin system’ that would morph in reaction to moisture in the air. Looking into past studies regarding the ability for building systems to become enhanced due to ‘shifting environmental conditions,’ the authors became inspired, envisioning new concepts for architectural 4D frameworks-along with embracing the concept of unpredictability within these frameworks that can be viewed as opportunities to learn. Forging straight ahead into the 4D, the Pennsylvania State University researchers delve more comprehensively into smart materials and how they are able to morph depending on user requirements and changes in the environment-whether due to temperature, moisture, or other elements. In ‘ Designing for Shape Change: A Case study on 3D Printing Composite Materials for Responsive Architectures,’ Elena Vazquez, Benay Gursoy, and Jose Duarte present details on customizing parts to optimize shape changing behavior. The post Coding for 3D Part 4: Rhino, Grasshopper and Weaverbird Setup appeared first on | The Voice of 3D Printing / Additive Manufacturing. So look out for that in our next article. It flows better and it makes the ability to iterate more intuitive. I realize the importance of 2D drawing and going to the 3D level as it makes product creation much easier. I am excited to somewhat learn the mindset of an “architect” through operating in this program.įor the next installment of this series, we will try to make a simple 2D parametric design that can be extruded into 3D form. The mind of an architect is very expansive, so their tool of choice needs to have various tools within its utility belt. Various software packages I have used are expansive, but Rhino seems to take things to a different level. Something I appreciate from Rhino is how extensive the program is from just looking at it briefly. It is a great plugin due to its ability to help in fabrication as well as rapid prototyping of ideas. This plugin allows us to automate subdivisions and reconstructing of shapes. It gives a designer the ability to make known subdivisions and transformation operators. The second plugin of choice for us is Weaverbird. The ability to create intriguing geometry quickly and with comparative ease is the main benefit of Grasshopper. It also gives you the ability to reference geometrical objects from Rhino. It uses a visual programming language vs. Grasshopper is an algorithmic modeling plugin for Rhino. The first plugin of interest to use is Grasshopper. We will focus on two plugins for Rhino in this series. These plugins are the essence of utility. The biggest advantage of Rhino is the number of plugins available for it. Otherwise our curiosity may let us stray from our path to getting things done. A lot of what Rhino has tool wise does look intriguing, but we will stay focused when using it. I would not benefit from a large overview of Rhino at this point. This allows me to get to the meat of what I want to do quickly. My goal with Rhino is to build parametric designs through coding, so I have a precise route to learning. This is a methodology I take in terms of technical project building as well as physical product manufacturing. Something important to remember is that having various tools is often not the best route when building anything. It has various plugins and tools ready for your disposal. No disrespect to Rhino as a package as it is great, but it seems to have a steep learning curve. I have used various 3D modeling environments and software, but Rhino’s interface is a lot to handle. When I first opened Rhino, frankly I was intimidated. After going through the download instructions, we can now use Rhino. To do so check out this link for a free 90 day trial version of Rhino. We will go through some of these items in this article while highlighting some other integral parts.įirstly we need to download Rhino for our modeling purposes. Even with our build environment, there are specific subtle things we need to do for our purposes of creation. Setting up the build environment is simple enough, but it is vital. After doing research on how we are going to attack this series with our toolbox of resources, we are setting up our environment for exploration.
