Fabrications

For a research project with Avşar Gürpınar in 2024, we studied lace patterns. During this process, I had the opportunity to try out two Grasshopper plugins: Parakeet and Clipper. When combined, they allow you to obtain laser-cutting patterns. Parakeet is a very good plugin that generates tessellations. This was something I always dreamed of developing back in my youth. 2-Uniform Tiling In this design, I used the Parakeet component named 2-Uniform Tiling. In geometry and tiling theory, a 2-uniform tiling…

Hot-wire cutting (HWC) is a cost-effective subtractive fabrication technique used across many industries. The basic idea of HWC is to cut a block of material by melting it with a resistance-heated wire under tension. It is effective for materials with low melting temperatures, such as expanded polystyrene (EPS) and extruded polystyrene (XPS). Generally, HWC is associated with mold production in the architecture, engineering, and construction (AEC) industries. Robotic hot-wire cutting (RHWC) is a subtopic of HWC. In a standard RHWC…

Three-dimensional concrete printing (3DCP) is an innovative digital fabrication and automation technique based on additive manufacturing that enables the creation of complex and customized structures in the architecture and construction industry. Its most notable advantages include eliminating formwork costs and labor (Buswell et al., 2020; Lyu et al., 2021; Kaliyavaradhan et al., 2022) and facilitating the fabrication of structural elements with complex curvatures, particularly in printing systems utilizing industrial robotic arms (Alabbasi et al., 2023; De Soto et al., 2018)….

This project aims to promote the widespread use of earthen architecture in new urban and rural developments, in line with the overarching goal of sustainable cities. The potential solutions earthen architecture offers across various dimensions, such as human health, efficient resource utilization, locality, economic viability, and cultural continuity, can only be realized to the extent that they are integrated into the construction sector. When the vernacular knowledge embedded in local architectural solutions is enhanced through modern design-to-production technologies, earthen architecture…

We continued the previous week’s experiments with Efecan. Using the sandblasting tool, we started performing point and line tests. The Grasshopper script I developed for this process is below. It allows us to move the gun along defined paths or execute target shots at specific points. To mount the IBIX pressurized gun onto the Kuka KR-20 model robot, I 3D-printed a custom adapter using PETG. Although it required a bit of force, the gun fits tightly into the adapter; it…

The 2025 IAAC Istanbul Summer school was conducted at İstanbul Bilgi University last year. Yesterday, a video was published about it on YouTube. It was prepared by Arkitekt. Here is the video: This reminded me the workshop and I decided to write about my side of the study. The reciprocal structure was designed by Gamze Gündüz, where she finalized it using a Grasshopper code. Then, the timber elements were labeled and sized with the help of Grasshopper again and integrated…

Today, Efecan and I attached the sandblasting device to the robotic arm. The device sprays a special sandblasting material onto surfaces using air pressure. Thus, it is used for cleaning moldy and dirty surfaces in buildings under restoration. Under normal conditions, the sandblasting gun is controlled manually. If the cleaning is too light, it remains insufficient, but it shouldn’t be so intense as to erode the stone either. Normally, the operator performs this control visually. Here, the potential uses for…

Urban Atölye, led by architect Nilüfer Kozikoğlu initiated the development of this Grasshopper code. The concept was to create a random relief pattern on a surface to be carved out using CNC technology. In Turkish, this technique is referred to as “kaşıklama,” as the resulting shapes resemble those carved out by a spoon. Consequently, I named this Grasshopper definition “spooning.” The definition employs the Populate Geometry component to achieve a random distribution. However, you can further refine it to allow…

The Image Sampler has always been a very effective Grasshopper component. Once again, I had the opportunity to use this component for a professional job. As you can see, with the help of a straightforward and short script, we can create a relief of an image to fit the desired panel dimensions on the screen. We can process this onto a suitable material using a CNC mill, laser cutter, or water jet. For the beginners, here are the image sampler…

This is a robotic fabrication student project developed in the Digital Fabrication elective course in 2018. This group of students experimented with the hot wire cutting of EPS foam. Their aim was to create curved surfaces by using a straight wire. Design research started with a literature study of precedents. Then, after several cutting experiments with the available hotwire cutter tool, they gained better control over the technology. However, they found the available tool too large and inefficient. They decided…
