“…The interest in this technology originates primarily in the ability to create geometrically complex parts as one-offs relatively fast and without major fixed tooling costs. Early work in ceramics was conducted by or under the supervision of Koshnevis (11). The group developed an approach called contour crafting, whereby a gantry or other mechanism is used to deposit relatively viscous clay in beads onto a flat base surface.…”

Research in ceramic material systems at Harvard University has introduced a range of novel applications which combine digital manufacturing technologies and robotics with imaginative design and engineering methods. Prototypes showcase the new performative qualities of ceramics and the integration of this material in today's construction culture. Work ranges from daylight control systems to structural applications and a robotic tile placement system. Emphasis is on integrating novel technologies with tried and true manufacturing methods. The paper describes two distinct studies -one on 3D printing of ceramics, the other on structural use of large format thin tiles.Keywords: 3D Printing; Adjustable Mold; Structural Tile: Cold-Bending.

“…Otomatik yapı üretim teknolojisinin en önemli avantajları çok çeşitli malzemelerin kullanılabilmesi, kalıp kullanılmaması ve üretim hızının yüksek olmasıdır. Farklı malzemelerin kullanabilme imkânı ve hızlı üretim yapabilmesi nedeniyle bu teknoloji acil uygulamalar, düşük maliyetli ev ve barınma yapıları ihtiyacını karşılamak için büyük bir potansiyele sahiptir [5,6]. Ayrıca bu teknoloji daha fazla tasarım özgürlüğü, daha iyi bir yapım kalitesi ve daha düşük bir maliyetle beton yapılar inşa etmek için geleneksel üretim yöntemleri *İlgili yazar: melihsahinoz@hotmail.com yerine alternatif olabilir [7].…”

Özet: Otomatik yapı üretim teknolojisi robotik temellidir ve katmanlı üretim teknolojisini kullanarak bilgisayar kontrolü altında büyük ölçekli nesneleri kalıp kullanmadan 3 boyutlu beton yazıcı cihazı aracılığıyla inşa edebilir. Bu çalışmanın amacı otomatik yapı üretim teknolojisinde, 3 boyutlu beton yazıcı cihazında kullanılabilecek uygun kıvamdaki harçları, düşük maliyetli en uygun malzemelerle oluşturabilmektir. Sonuç olarak düşük maliyetli malzemeler araştırılarak bu malzemeler kum, diatomit, çimento, öğütülmüş yüksek fırın cürufu, selüloz ve polipropilen lif olarak belirlenmiştir. Bu malzemeler kullanılarak 3 boyutlu beton yazıcı cihazında kullanılabilecek uygun kıvamda 7 adet deneme karışımı tespit edilmiştir. Bu karışımlar ile yoğunluk tayini, yayılma, basınç ve eğilme dayanımı deneyleri yapılmış, çökme deneyi ile kullanım süreleri belirlenmiş ve karışım oranları verilmiştir. Bu 7 adet deneme karışımlarından birinci olarak Deneme 2, ikinci olarak Deneme 3 ve üçüncü olarak Deneme 7'nin, 3 boyutlu beton yazıcı cihazında kullanımının diğer karışımlara göre daha uygun olduğu belirlenmiştir. Determination of the Materials that Can Be Used in Automated Construction Production TechnologyKeywords Automated construction, Robotic construction, 3D printing, Construction materials Abstract: Automatic construction production technology is based on robotic technology. With this technology large-scale objects can be constructed without using formwork with 3d printer by using additives under computer controlling. The aim of this study is to be able to make mixtures suitable for 3d concrete printer that can be used in automatic construction production technology with low-cost and most suitable materials. Consequently, low price materials were investigated and sand, diatomite, cement, ground blast furnace slag, cellulose and polypropylene fiber were determined as low price materials. 7 test mixtures in suitable consistency were determined to be used in 3d concrete printer by these low price materials. With these mixtures determination of density, spreading, compressive and flexural strength tests were performed. Exposure times were identified by slump test and mixture ratios were given. Out of these seven test mixtures, first of all Trial 2, secondly Trial 3, thirdly Trial 7 were defined as the most suitable ones in 3d concrete printer compared to other mixtures.

“…Considering materiality and architecture at multiple scales, there are a few examples that bring the two together. For instance, a scaled up printing machine is horizontally depositing layer-by-layer a cement-based building material (Khoshnevis, 2001;Dini et al, 2006;Kestelier, 2012) without taking locally changing structural and climatic constraints into account. Hyperbody's D2RP project proposes an alternative method of additive material deposition by integrating local and global material optimization routines in the process while taking the simulated and real behaviors and properties of the material into consideration.…”

Hyperbody's materially informed Design-to-Robotic-Production (D2RP) processes for additive and subtractive manufacturing aim to achieve performative porosity in architecture at various scales. An extended series of D2RP experiments aiming to produce prototypes at 1:1 scale wherein design materiality has been approached from both digital and physical perspectives were recently implemented. At digital materiality level, a customized computational design framework for compression only structures has been developed, which was directly linked to the robotic production setup. This has enabled the systematic study of physical materiality, which cannot be fully simulated in the digital medium. The established feedback loop ensured not only the development of an understanding for material properties in relation to their simulated and real behaviours but also allowed to robotically additively deposit and/or subtractively remove material in order to create informed material architectures at 1:1 scale.
