Malaguti rear arm
Malaguti (link) uses topology optimization for their motorcycle’s rear arm. Instead of giving all the load cases to the optimization software, they optimized the part for different load cases, and combined the results themselves, which seems like a reluctant to … Continue reading
Industrial Design
Luca Frattari from Faculty of Architecture University of Camerino (link) experimented on usage of topology optimization with industrial design. Chairs were designed and produced by Objet 3-D printing machines.
Permobil – Swerea wheelchair linkage
Swerea, a Swedish R&D company, developed a wheelchair linkage for Permobil utilising topology optimization (link). The original part was forged aluminium weighting 1.3 kg. Different manufacturing techniques were considered, aluminium high pressure die-cast part was the cheapest but did not … Continue reading

Sacmi hydraulic press
The hydraulic press by Sacmi (link1, link2) was designed using topology optimization.The topology optimized shape is displayed in the final product, which looks extraordinary for an industrial machine. The name of this series of presses is Android indeed.
ZF Ship Gearbox Housing
ZF uses topology optimization to develop a Ship Gearbox Housing (link). The design combines thrust bearing into the gearbox. Thrust bearing deals with the loads that arise from the propeller (or jet). So loads are huge. The special criteria that … Continue reading

Concrete Aesthetics
This article surveys topology optimization from an aesthetical and architectural point of view. The project was carried under the name of “Unikabeton – Industrial production of unique concrete elements via digital fabrication” with many contributers. The enterance page http://fluxstructures.net also … Continue reading
Formula SAE car bell crank
As a master thesis study (link) a Formula SAE cars bell crank was topology optimized. The bell crank is highly stressed, the largest load acting on it being 3500 N. The cranks weight was reduced to 140 grams which is … Continue reading
