(author), Weinans, Harrie (author), Zadpoor, A.A. (author)Additive manufacturing (AM) techniques enable fabrication of bone-mimicking meta-biomaterials with unprecedented combinations of topological, mechanical, and mass transport properties. The mechanical performance of AM meta-biomaterials is a direct function of their topological design. It is, however, not clear to what extent the material type...journal article 2018

Verhoef, L.A. (author), Budde, Bart (author), Chockalingam, Cindhuja (author), García Nodar, Brais (author), van Wijk, A.J.M. (author)The effect of disruptive technologies unrelated to the energy sector, such as additive manufacturing (AM), tends to be overlooked in energy scenarios. The present research assessed the potential effect of AM on the global energy demand in four energy scenarios for 2050 with extended versus limited globalisation and limited versus extensive...journal article 2018

Hedayati, R. (author), Hosseini-Toudeshky, H. (author), Sadighi, M. (author), Mohammadi-Aghdam, M. (author), Zadpoor, A.A. (author)Advances in additive manufacturing (AM) techniques have enabled fabrication of highly porous titanium implants that combine the excellent biocompatibility of bulk titanium with all the benefits that a regular volume-porous structure has to offer (e.g. lower stiffness values comparable to those of bone). Clinical application of such...journal article 2018

Li, Y. (author), Han, Qinglin (author), Zhang, Guangjun (author), Horvath, I. (author)Robotic wire and arc additive manufacturing (WAAM) systems are required to provide predictable and efficient operations to fabricate solid metallic parts with high morphological fidelity and geometric accuracy. Since the metallic parts are fabricated based on a layer-by-layer principle, the interactions between the neighboring beads and...journal article 2018

(author), Cheng, Lin (author), Liang, Xuan (author), To, Albert. C. (author)Manufacturing-oriented topology optimization has been extensively studied the past two decades, in particular for the conventional manufacturing methods, for example, machining and injection molding or casting. Both design and manufacturing engineers have benefited from these efforts because of the close-to-optimal and friendly-to-manufacture...journal article 2018

Hedayati, R. (author), Sadighi, M. (author), Mohammadi-Aghdam, M (author), Hosseini-Toudeshky, H (author)Additive manufacturing techniques have made it possible to create open-cell porous structures with arbitrary micro-geometrical characteristics. Since a wide range of micro-geometrical features is available for making an implant, having a comprehensive knowledge of the mechanical response of cellular structures is very useful. In this study,...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

Zadpoor, A.A. (author)Additive manufacturing (AM) (=3D printing) has emerged during the last few years as a powerful technological platform for fabrication of functional parts with unique complex geometries and superior functionalities that are next to impossible to achieve using conventional manufacturing techniques. Due to their importance in industrial...contribution to periodical 2018

Sakes, A. (author), Hovland, Kevin (author), Smit, G. (author), Geraedts, Jo M.P. (author), Breedveld, P. (author)In current bipolar electrosurgical instruments, a high frequency electrical sinusoidal wave is passed through the patient's body from an active electrode to the return electrode to cut, coagulate, or desiccate tissues. Even though current bipolar electrosurgical instruments have proven effective in minimizing blood loss, advancement is needed...journal article 2018

Langelaar, Matthijs (author)Additive manufacturing (AM) enables the fabrication of parts of unprecedented complexity. Dedicated topology optimization approaches, that account for specific AM restrictions, are instrumental in fully exploiting this capability. In popular powder-bed-based AM processes, the critical overhang angle of downward facing surfaces limits...journal article 2018

van de Ven, E.A. (author), Maas, Robert (author), Ayas, C. (author), Langelaar, Matthijs (author), van Keulen, A. (author)Additive manufacturing enables the nearly uncompromised production of optimized topologies. However, due to the overhang limitation, some designs require a large number of supporting structures to enable manufacturing. Because these supports are costly to build and difficult to remove, it is desirable to find alternative designs that do not...journal article 2018

(author), Weinans, Harrie (author), Jahr, H. (author), Zadpoor, A.A. (author)An ideal bone substituting material should be bone-mimicking in terms of mechanical properties, present a precisely controlled and fully interconnected porous structure, and degrade in the human body to allow for full regeneration of large bony defects. However, simultaneously satisfying all these three requirements has so far been highly...journal article 2017

Sauerwein, M. (author), Bakker, C.A. (author), Balkenende, R. (author)Circular product design is a relatively new approach to design suitable strategies to realize circular products. Additive manufacturing (AM) is seen as a promising enabling production process. It has digital and additive characteristics, which makes AM different from conventional production techniques. However, it is yet unclear how this...conference paper 2017

Wu, J. (author), Clausen, Anders (author), Sigmund, Ole (author)Additively manufactured parts are often composed of two sub-structures, a solid shell forming their exterior and a porous infill occupying the interior. To account for this feature this paper presents a novel method for generating simultaneously optimized shell and infill in the context of minimum compliance topology optimization. Our method...journal article 2017
