Bolanos Arriola, J. (author), van Oudheusden, A.A. (author), Flipsen, Bas (author), Faludi, Jeremy (author)This guide takes the reader through the 3D Printing for Repair (3DP4R) process. It consists of guidelines and tools to create a 3D printable version of spare parts needed for a product repair. 3D printing a spare part is more than just printing the original part. Instead, it is an iterative process in which the part is analysed, redesigned,...book 2022

Tissen, L.N.M. (author)3D printing’s rapid technological development is starting to impact the art field because, for the first time, it has become possible to exactly reproduce and reconstruct artworks without any loss of their physical features. Yet, a coherent overview of how 3D printing is used within the art field while paying attention to ethical considerations...book chapter 2022

Boon, W.P.C. (author), van Wee, G.P. (author)3D printing (3DP) is an emerging technology associated with a more tailor-made, distributed way of manufacturing which, if successful, is bound to have repercussions on transport, supply chains, and logistics. This contribution delves into what 3DP is, how it will influence consumer wants and needs, location choices and transport resistance, and...book chapter 2021

Chang, Z. (author), Schlangen, E. (author), Šavija, B. (author)This paper reports an extended lattice model for printing process simulation of 3D printed cementitious materials. In this model, several influencing factors such as material and geometric nonlinearity are considered. Using this model, green strength of cementitious material is investigated, deformation and crack pattern can be derived, which...book chapter 2020

Calabrese, G.C. (author), Hidding, A.J. (author), Bier, H.H. (author)This chapter presents a review of cementless materials for 3D printing, with a specific emphasis on the utilization of volcanic ash in the context of a case study for off-Earth construction. As a highly promising alternative to traditional concrete, selected binders are investigated in relation to volcanic ash for the creation of an alternative...book chapter 2024

Elkhuizen, W.S. (author), Zaman, T. (author), Verhofstad, W. (author), Jonker, P.P. (author), Dik, J. (author), Geraedts, J.M.P. (author)Paintings are near-planar objects with material characteristics that vary widely. The fact that paint has a material presence is often overlooked, mostly because we often encounter these artworks in the form of two-dimensional reproductions. Capturing paintings in the third dimension is not only important for study, restoration and conservation,...conference paper 2014

Samenjo, K.T. (author), van Oudheusden, A.A. (author), Bolanos Arriola, J. (author), Flipsen, Bas (author), Faludi, Jeremy (author)The Sharepair project aims to decrease the waste of electronic and electric consumer products and increase their useful life, by supporting repair communities and scaling up citizen repairs through digital tools. One of the focus areas of this project is to support the discovery or manufacturing of spare parts. With a 3D CAD model of a part and...conference paper 2022

Xu, Y. (author), Šavija, B. (author), Schlangen, E. (author)Traditionally, mechanical properties of cementitious materials are designed<br/>“chemically”, namely by configuring their mix proportions. Owning to the development of 3D printing technology, “physical” tailoring the meso-structure of cementitious materials to design their mechanical properties becomes possible. In the present study,...conference paper 2019

Jovanova, J. (author), Var, S.C.S. (author)Underwater robot tasks pose many challenges for conventional robotic systems. The current rigid robots are limited in their adaptability to the environment and the objects to be manipulated. Soft grasping of objects offers advantages due to the flexibility when dealing with, for example, living organisms, random shaped objects, and coral...conference paper 2023

Saleh, Charbel Miled Nohra (author), Louter, P.C. (author), Turrin, M. (author)This paper investigates the stiffness and the durability of a composite panel that consists of thin glass as outer layers and a 3D printed core element from recycled PET. Thin alumino-silicate glass, mostly used for displays in computers, tablets and smartphones, is known for its flexibility, durability and high bending strength. However, for...conference paper 2020

Kuipers, Tim (author), Doubrovski, E.L. (author), Verlinden, J.C. (author)This work presents halftoning techniques to manufacture 3D objects with the appearance of full grayscale imagery for Fused Deposition Modeling (FDM) printers. While droplet-based dithering is a common halftoning technique, this is not applicable to FDM printing, since FDM builds up objects by extruding material in semi-continuous paths. A set...conference paper 2017
