Clay printing has the same characteristics as 3D printing, and the construction concept of generating forms is mainly stack printing. By thinking about how to combine the printing of clay with the application of actual building construction, it can be applied to the building curtain wall system by utilizing the characteristic of diffuse reflection on the surface porous holes. By changing the orientation, size and density of the openings of the layered print, the intensity of sunlight entering the building through the curtain wall is controlled.

We found that in the 24-hour working environment of the American Emergency Alarm Center, it is required that the computer screen cannot produce any reflection, so as not to delay the viewing of any emergency alarm information. Therefore, in order to prevent the computer screen from reflecting on the computer screen because of the existence of natural light sources, it interferes with the office. Therefore, the wall of the building is generally closed, and artificial light sources are used throughout the day. This not only increases office pressure, but also Mental health also has a huge impact. Therefore, we hope that the porous surface of the clay surface can form the characteristic of diffuse reflection and apply it to the building curtain wall system. It can work without introducing reflection interference to the computer screen while opening the external field of vision, and introducing natural light sources into the room.

This solution can be applied in the transformation of the office environment. In the office environment of the emergency treatment center, in order office exterior walls increase the pressure on the staff. By applying the clay panel of the scheme to the curtain wall, by controlling the orientation, and relying on the upper part of the sunlight. Shooting indoors does not interfere with computer screens that require 24 hours of work.

Concept Assembly

Each piece of 600mm x 600mm size is connected to each other by steel members. The four-sided steel is fixed like a frame to prevent the clay panel from being damaged by shear. Each panel is bolted together with two angles. In this detail we have thought of two detail treatments. One is to reserve a circle for the clay panel when printing, and clamp the edge with U-shaped steel. The other is to connect them by angle steel.

order to avoid the reflection interference caused by the direct sunlight, the large-scale use of artificial light sources and the application of closed orientation, height and opening size of the voronoi polygon rotation, the lower part of the sunlight enters directly, creating a good office environment

Shapr Generation

On the basis of the Thiessen polygon, each layer is rotated uplifted, and each height is raised by 3mm (that is, the thickness of a layer of clay), and the next shape is reconnected at a distance of 5% from the side of each polygon. The secondary loop gets a shape with smaller and smaller aperture.
