Softkill: 3D打印預制住宅

本項目探討了利用3D打印技術建造由預制建筑件構成的住宅的可能性。作為一種增材制造工藝，3D打印技術可使各種不同設計由出自同一臺機器的材料拼裝而成，雖然工藝復雜，但不增加額外的制造成本。此外，增材制造幾乎可以實現(xiàn)零浪費。本項目對這種潛在復雜性增加對于優(yōu)化結構性能的可能性進行了研究探討，以減少建筑的總材料用量。這種設計采用了一種定制的拓撲結構優(yōu)化方法，以確保在設計中沒有任何地方的材料是不承受結構荷載的。此外還采用了仿真模擬的設計算法，以通過建筑物內部的應力和應力方向確定材料的顆粒方向和孔隙率。這就形成了一種極具裝飾性的多孔設計，這種設計在局部上存在差異，并且只用了等比例建筑物所通常需要使用的材料量的一小部分。這樣產生了一種體積大而多孔的建筑類型。該項目通過數(shù)字腳本開發(fā)，并通過一個由大量不超過1mm厚的構件組成的1:33大比例模型原型進行測試。該模型本身由15個部分組裝而成。

This project explores the potentials of 3D Printing to construct a house composed of prefabricated building components. As an additive manufacturing process, 3D Printing enables a wide variety of different designs to be fabricated from the same machine, with complexity not adding additional costs to the fabrication. Additionally, additive manufacturing operates with almost zero percent waste. This increase in potential complexity was investigated for its opportunity in optimising structural performance in order to reduce overall material quantities of the construction. The design utilised a custombuilt topological structural optimisation method to ensure no material was placed within the design that was not undergoing any structural loading. Agent-based design algorithms were also implemented to locally determine material grain direction and porosity in relation to stress and stress orientation within the building. This results in a highly ornamental porous design that is locally differentiated and utilises a fraction of material normally utilised within similar scale buildings. This results in a building typology that is volumeous yet porous. The project was developed through digital scripts and tested on a large 1:33 scale model prototype comprised of a multitude of elements no more than 1mm thick. The model itself is assembled from 15 parts that contribute to the overall assemblage.
