A new method for assessing anisotropy in fused deposition modeled parts using computed tomography data
Tronvoll, Sigmund Arntsønn; Vedvik, Nils Petter; Elverum, Christer Westum; Welo, Torgeir (Journal article; Peer reviewed, 2019)Voids in fused deposition modeled (FDM) parts are assumed to be a key driver for their anisotropic behavior. However, these assumptions are based on investigations of voids using only 2D data (microscopy images). This paper ... -
Creating the brain of Staale - A navigation system for an autonomous Ackermann-steered litter robot
Eine, Stian Løcka; Norli, Kristoffer (Master thesis, 2022)Søppel i gater og offentlige parker har økt drastisk de siste tiårene. Med påvirkning på dyreliv, vannkvalitet og menneskers oppfattelse av lokale områder, påvirker forsøpling miljøet negativt, både lokalt og globalt. I ... -

Fossheim, Emil (Master thesis, 2020)Denne oppgaven evaluerer konsepter for et forbedret design av flomvern-systemer utviklet av AquaFence AS. Hovedfokuset var å vurdere ulike løsninger for hovedpanelene som er brukt i systemet. Arbeidet ble utført ved grundig ... -
Dimensional accuracy of threads manufactured by fused deposition modeling
Tronvoll, Sigmund Arntsønn; Elverum, Christer Westum; Welo, Torgeir (Journal article; Peer reviewed, 2018)For parts manufactured by fused deposition modeling (FDM), helical threads drawn in accordance with normal standards (e.g. ISO 68-1), tend to end up deformed when manufactured. These dimensional imperfections typically ... -
Eliciting unknown unknowns with prototypes: Introducing prototrials and prototrial-driven cultures
Jensen, Matilde Bisballe; Elverum, Christer Westum; Steinert, Martin (Journal article; Peer reviewed, 2017)This paper maps and describes how prototypes are used to elicit requirements of unknown unknowns in industry. Eight engineering design companies serve as a dataset for a multi-case investigation. By semi-quantitatively ... -
High-performance polymer 3D printing – Open-source liquid cooled scalable printer design
Birkelid, Andreas Hagerup; Eikevåg, Sindre Wold; Elverum, Christer Westum; Steinert, Martin (Peer reviewed; Journal article, 2022)To print high-performance polymers, a stable running printer that can reach high temperatures is needed. There is currently a lack of low-cost solutions that allow manipulation of process parameters and expansion of sensors ... -
Investigating pressure advance algorithms for filament-based melt extrusion additive manufacturing: theory, practice and simulations
Tronvoll, Sigmund Arntsønn; Popp, Sebastian; Elverum, Christer Westum; Welo, Torgeir (Journal article; Peer reviewed, 2019)Purpose – This paper aims to present the mathematical foundation of so-called advance algorithms, developed to compensate for defects during acceleration and deacceleration of the print head in filament-based melt extrusion ... -
