Additiv Tilvirkning som Produksjonsmetode for Verktøyholdere
Grøstad, Erling (Master thesis, 2016)Additiv tilvirkning (AM) er en produksjonsmetode der en lagvis bygger opp komponenter basert på informasjon fra en 3-dimensjonal modell uten behov for å først produsere verktøy som for eksempel støpeformer eller ... -
Additive Manufacturing by Robot: An Overview of the State-of-the-Art and Proof-of-Concept Results
Evjemo, Linn Danielsen; Moe, Signe; Gravdahl, Jan Tommy; Roulet-Dubonnet, Olivier; Brøtan, Vegard; Gellein, Lars Tore (Chapter, 2017)For the last decades, additive manufacturing (AM) has become an ever increasing part of the development of new technology and devices. However, it is still challenging to use this technology on a larger scale. This paper ... -
Additive Manufacturing for High Value Metal Production in an Optimized Hybrid Manufacturing Cell
Brøtan, Vegard (Doctoral thesis at NTNU;2015:29, Doctoral thesis, 2015)The in-between processes have also been investigated. In the hybrid cell, the surface roughing is done by a surface milling operation in the milling machine, contrary to the traditional sand blasting operation. And, there ... -
Additive manufacturing of thin-walled structures by robot manipulator : An experimental approach focusing on arc welding
Evjemo, Linn Danielsen (Doctoral theses at NTNU;2022:208, Doctoral thesis, 2022)Additive manufacturing (AM) has, over recent decades, become a quickly evolving and ever more present part of production and manufacturing. It has gone from being a simple prototyping method to building more complex ... -
Ballistic impact resistance of additive manufactured high-strength maraging steel: An experimental study
Costas, Miguel; Edwards-Mowforth, Maisie; Kristoffersen, Martin; Teixeira-Dias, Filipe; Brøtan, Vegard; Paulsen, Christian Oen; Børvik, Tore (Peer reviewed; Journal article, 2021)Maraging steel is a low carbon steel known for its ultra high-strength after heat treatment. In combination with Additive Manufacturing (AM), the properties of maraging steel indicate potential to enable complex geometries ... -
Design Considerations for a Directed Energy Deposition Cell
Hassel, Trond Arne; Brøtan, Vegard; Sørby, Knut (Chapter, 2023)Setting up a robotised additive manufacturing machine requires attention to several safety aspects, including integration of different systems, a functional work area, human-machine interfaces and convenience in operation. ... -
Fluid flow through 3D-printed particle beds: a new technique for understanding, validating, and improving predictability of permeability from empirical equations
Gjengedal, Sondre; Brøtan, Vegard; Buset, Ole Tore; Larsen, Erik; Åsebø Berg, Olav; Torsæter, Ole; Ramstad, Randi Kalskin; Hilmo, Bernt Olav; Frengstad, Bjørn (Peer reviewed; Journal article, 2020)The application of 3D technology for fabrication of artificial porous media samples improves porous media flow studies. The geometrical characteristics of a porous media pore channel: the channel shape, size, porosity, ... -
In-situ X-ray microtomography of interface between additively manufactured aluminium bronze and H13 tool steel
Linga, Håkon; Zhang, Yubin; Brøtan, Vegard; Ren, Xiaobo; Westermann, Ida; Holmedal, Bjørn (Peer reviewed; Journal article, 2022)Directed energy deposition (DED) is an additive manufacturing process category where material is melted as it is deposited, often powder melted with a focused laser. In this work aluminium bronze was deposited onto H13 ... -
Instrumentering av dempede borstenger
Brøtan, Vegard (Master thesis, 2010)Målet med prosjektet var å finne og teste alternative måter for overvåkning av lange borstenger. Det har i en tidligere rapport med navn ”Innvendig maskinering av jetmotorakslinger” blitt drøftet bruken av strekklapper til ... -
On the ballistic perforation resistance of additive manufactured AlSi10Mg aluminium plates
Kristoffersen, Martin; Costas, Miguel; Koenis, Tim; Brøtan, Vegard; Paulsen, Christian Oen; Børvik, Tore (Journal article; Peer reviewed, 2019)Materials and structures made through additive manufacturing (AM) have received a lot of attention lately due to their flexibility and ability to customize structural components of complex geometry. One range of application ... -
