van Manen, T. (author), Janbaz, S. (author), Zadpoor, A.A. (author)Shape-shifting of flat materials into the desired 3D configuration is an alternative design route for fabrication of complex 3D shapes, which provides many benefits such as access to the flat material surface and the ability to produce well-described motions. The advanced production techniques that primarily work in 2D could then be used to...review 2018

(author)Biomimetic composites are usually made by combining hard and soft phases using, for example, multi-material additive manufacturing (AM). Like other fabrication methods, AM techniques are limited by the resolution of the device, hence, setting a minimum length scale. The effects of this length scale on the performance of hard-soft composites...journal article 2018

Cuellar Lopez, J.S. (author), Smit, G. (author), Zadpoor, A.A. (author), Breedveld, P. (author)In developing countries, prosthetic workshops are limited, difficult to reach, or even non-existent. Especially, fabrication of active, multi-articulated, and personalized hand prosthetic devices is often seen as a time-consuming and demanding process. An active prosthetic hand made through the fused deposition modelling technology and fully...journal article 2018

Mirzaali, Mohammad J. (author), Caracciolo, A. (author), Pahlavani, H. (author), Janbaz, S. (author), Vergani, L. (author), Zadpoor, A.A. (author)Up until recently, the rational design of mechanical metamaterials has usually involved devising geometrical arrangements of micro-architectures that deliver unusual properties on the macro-scale. A less explored route to rational design is spatially distributing materials with different properties within lattice structures to achieve the...journal article 2018

Ahmadi, S.M. (author), Ashok Kumar Jain, R. K. (author), Zadpoor, A.A. (author), Ayas, C. (author), Popovich, V. (author)Titanium and its alloys such as Ti6Al4V play a major role in the medical industry as bone implants. Nowadays, by the aid of additive manufacturing (AM), it is possible to manufacture porous complex structures which mimic human bone. However, AM parts are near net shape and post processing may be needed to improve their mechanical properties....journal article 2018
