Our company develops various products utilizing shape processing, function calculation, and design technologies. In this article, we explain Implicit Function Modeling, one of the means of modeling geometry.

We continue to build our in-house software environment to advance our unique structural design. The components of the software environment are diverse, but one of them is the freely extensible geometry processing-numerical analysis environment, and we are extensively using Rhinoceros, a 3D CAD system, and its plug-in, Grasshopper, in an extended manner. In this article, I hope to write mainly about the important but rarely mentioned aspects of developing and using Grasshopper plug-ins. As someone who got hooked on Rhino+Grasshopper as a student and has been doing this kind of work ever since, I hope I can help a lot of people get started.

Nature Architects is often thought of as a company that designs for 3D printers, but in reality, Nature Architects designs for manufacturing methods commonly used in mass production (injection, press, extrusion, etc.) to improve functionality and reduce cost in ways that are not possible with conventional design. In this article, Nature Architects will introduce some of our recent projects with clients and show how we design for existing manufacturing methods.

We continue to build our in-house software environment to advance our own structural design. The components of the software environment include a wide range of commercial software and in-house FEM solvers, etc. One of these is Rhinoceros, a 3D CAD system, and its plug-in Grasshopper, which we have extended and widely We are using Rhinoceros 3D CAD and its plug-in Grasshopper extensively. There are various excellent tutorials, videos, blogs, etc., including official ones, so please refer to them for the basics. I hope to write mainly about important but rarely mentioned aspects of Grasshopper in order to extend and use Grasshopper by yourself. Those who are interested in Rhinoceros+Grasshopper 2. those who want to deepen their understanding of the internal processing of Rhinoceros+Grasshopper 3. those who want to extend Rhinoceros+Grasshopper for their own work, research, hobby, etc. 4. those who want to design and play with metamaterials. Those who want to design and play with metamaterials.

The adidas "4DFWD" shoe, with a special 3D printed structure embedded in the midsole, has the function of converting the force of a step into propulsive force. This series of articles interprets this function as a mechanical metamaterial that converts compression into shear and explains how to design it. In this article, we will design a mechanical metamaterial with macro physical properties that convert compression to shear, measure its macro physical properties using the homogenization method, and conduct experiments by actually compressing a 3D printed specimen.

The adidas "4DFWD" shoe, which has a special 3D-printed structure embedded in the midsole, has the function of converting stepping force into propulsive force. This article interprets this function as a mechanical metamaterial that converts compression into shear and explains how to design it. This article explains the macro physical properties that convert compression into shear from the viewpoint of material mechanics.
