“…Hot-wire cutting is limited to thermally cuttable materials, whereas mycelium materials are composed of flammable lignocellulose fibers. Odico addressed these disadvantages by developing a diamond-threaded abrasive wire that rotates on electrically propelled flywheels [23], which not only increases the production speed but also allows for cutting solid materials.…”

“…The BESO-based plugin Ameba of Grasshopper for Rhinoceros (no further details which version) is used for toolpath planning in the context of robotic additive clay manufacturing. Søndergaard et al (2013), on the other hand, propose a combined integrated design, optimization and fabrication method for space-frame truss structures in the course of an autonomous digital process.…”

“…A different approach was chosen by Søndergaard et al (2019), who propose a method to industrially manufacture topology-optimized ultra-high performance concrete (UHPC) structures using robotic abrasive wire cutting of spatially advanced polystyrene formwork systems and CNC milling of timber or EPS. Their work is especially directed towards large-scale structures, thus sounding out practical boundaries.…”

Structural optimization within concrete construction has been increasingly taken up in research within the last two decades. Possible drivers are the need for material-reduced and thus resource-efficient structures as well as recent advancements in automated concrete construction. However, structural concrete is characterized by nonlinear material behavior. Consequently, the merge of structural concrete design and topology optimization is not trivial. This paper reviews and assesses the topic of topology optimization within concrete construction, carrying out an extensive quantitative as well as qualitative review on practical and numerical applications. The following research areas are identified: Multimaterial modeling, stress constraints, concrete damage modeling, strut and tie modeling, combined truss-continuum topology optimization, the consideration of multiple load cases, a focus on construction techniques and alternative approaches. Although the number of research papers dealing with the topic of topology optimization in concrete construction is numerous, there are only few that actually realized topology optimized concrete structures. In addition, only a little number of experiments was performed for an objective evaluation of the found geometries so far. Concluding this review, a list of future challenges, like the incorporation of sustainability measurements within the optimization process, is given and thus serves as a guidance for subsequent research.

“…Unexpectedly, the development that did occur affected not the material side of the system but the method of mechanical processing. Aspiring to cut down the lead time, the company contracted for fabrication of the formwork managed to produce the required geometry not with the CNC milling, but with robotic hot-wire cutting (RHWC) [2]. While this helped to reduce processing time by approximately 90%, it still required processing of 4500 m 3 of EPS foam to produce the formwork required for the in-situ concrete constructions used in the project [3].…”
