東京大学建築学専攻Digital Fabrication Lab(DFL)では、建築施工におけるデジタル技術の活用をテーマに、毎年実験的なパビリオンを制作しています。単に技術による自動化や高度化を目指すのではなく、そこに「人間が関わること」の可能性を探る実証の場として、これまで「人間と機械が融合した3Dプリンター」(2014年STIKパビリオン)や「巨大3Dペン」(2015年TOCAパビリオン)を建築スケールで再現してきました。

本年Computational Clayプロジェクトでは「人間が関わること」をより一層推し進め、個性としての身体パフォーマンスを建築表現に反映させるため、人の動きと素材と関係に着目したユニークなパネル加工システムを開発しました。

Every year in the University of Tokyo’s Digital Fabrication Lab (DFL), digital fabrication technologies are used to produce an experimental pavilion project. The aim, rather than being simply to achieve automation or precision through use of such technologies, is to explore the potentials for human and machine collaboration. Past projects have focused on fusions between humans and machines through the use of 3D printers: the 2014 STIK Pavilion explored this theme through guided aggregation, and the 2015 TOCA Pavilion by using humans as a parameter along with an oversized 3D pen.

This year, in the Computational Clay Pavilion, we advance the role of the human in construction one step further, examining how an individual’s capabilities and performance can be expressed in an architectural output. We have developed a unique panelized construction system wherein the movements of humans and their relationship to the material are explored.


The two images show the stages of panel production used for the 2016 pavilion project.

Panel Bag Sealing Steps (image 1):

Step 1: Wood chips are mixed with resin and poured into a pre-made wooden frame, which sits on top of a double layer of plastic bags to decrease possibility of holes forming.

Step 2: The frame is removed and another double layer of plastic is put on top of the wood chips. The outer bag is then closed with a heat sealer. Two adjacent lines of sealant help to prevent air leakage during vacuuming.

Step 3: The panel is vacuumed and any small holes that may be produced due to the combination of sharp wood chips and high pressure are taped.

Step 4: Reflective marker guidance system tracking points are applied. This is for the panel shaping process, which comes next.


Panel Shaping Process (image 2):

A Kinect camera uses an infrared projector to detect the contrast between reflective markers and the background. When it finds a point of contrast it produces a tackable point, which is then compared to predetermined points in the computer model. The manipulation of the panel is articulated according to the difference between the points on the model and the points (reflective markers) on the actual panel. After the panel has been shaped, the points are re-scanned to quantify the difference between the physical and computer models. A light-absorbing cloth is used as a backdrop to create total contrast between the panel and its environment. This allows the physical panel to be easily tracked and manipulated in space.
