獨特的、 獨一無二的建築元件、快速生成、符合經濟效益的.... 從先進的三維建模軟體發展直到現在，在 3D 列印的世界裡，這些關鍵字是還沒有被兌現的。傳統的 3D 列印作為一種設計工具，是成型過程中昂貴的一個環節，但往往又是生產中最重要的部分。然而，舊金山灣區的 Rael San Fratello 建築師事務所，發表了一個扳倒這些論點的作品。
Unique, one-of-a-kind building components, generated quickly and economically from advanced 3-dimensional modeling software – until now this promise of 3D printing was unfulfilled. Conventional 3D printing served as an expensive prototyping process, important as a design tool but falling short in production. However, this year the San Francisco Bay Area firm Rael San Fratello Architects has initiated a fundamental shift.

美國加利福尼亞大學伯克利分校（UC Berkeley）助理教授 Ronald Rael 進行的研究，透過該公司已開發的水泥基聚合物，以及一個新的進程方式，首次沿用常規的快速原型製造硬體，來產生堅固而耐久的建築元件；它的成本遠低於傳統快速成型材料—比粉印刷材料的成本還要低90%。材料也達到 4,700 psi 的精密度。這一種材料是透過數位建模軟體控制輸出，將為建築材料和合成工藝的設計、生產，帶來新的時代。
Through research Assistant Professor Ronald Rael conducts at the University of California Berkeley, the firm has developed a cement-based polymer and a new process that,for the first time, employs conventional rapid prototyping hardware to produce strong and durable building components that cost far less than conventional rapid prototyping materials—up to 90% less than comparable powder printing materials. The material can also reach strengths of up to 4,700 psi in compression. This advancement in material output from digital modeling software ushers in a new era in building materials, and a new synthesis of design and production.

SeatSlug，一個生物形態的長凳，詮釋如何從數位輸出的方式，透過 3D 軟體模型來生成最終產品與建築結構部分。這個作品的靈感來自於 flabellina goddardi，一種 2010 年在加州發現的新品種海蛞蝓，結合日本 karakusa 的無限花紋所設計出的作品。它是以 230 獨特的元件所製造快速製造而成。
The SeatSlug, a biomorphic interpretation of a bench, demonstrates how this new digital output process generates end-product structural building components directly from 3D software models. The design is inspired by flabellina goddardi, the newest species of sea slugs discovered in California in 2010, and by the infinite tessellations of Japanese karakusa patterns. It is constructed of 230 unique rapid-manufactured components.

蛞蝓的皮層，微妙的半透明與光澤；參觀的民眾獲得難忘的觸覺的體驗，是來自於這作品技術上的突破。
The sinuous form, subtle translucency and glossy finish engage viewers with a memorable aesthetic experience—a tactile personal encounter with a technological breakthrough.
