Conference Paper
Full-text available
The additive manufacturing (AM) of injection molding inserts has gained popularity during recent years primarily due to the reduced design-to-production time and form freedom offered by AM. In this paper, topology optimization (TO) is performed on a metallic mold insert which is to be produced by the Laser Powder Bed Fusion (LPBF) technique. First,...

Full-text available
This paper presents the methodology and results of an extensive benchmarking of laser powder bed fusion (LPBF) machines conducted across five top machine producers and two end users. The objective was to understand the influence of the individual machine on the final quality of predesigned specimens, given a specific material and from multiple pers...
Thesis
Full-text available
In this PhD project at DTU MEK, Mandaná Moshiri investigated how to define an integrated process chain for first time production of mould components to be used for plastic injection moulding using laser powder bed fusion metal additive manufacturing (AM) technologies. This technology is already used for fabricating injection moulding components, bu...
Article
Full-text available
Metal additive manufacturing (MAM) of mould components is associated with cost-intensive post-process finishing operations, which are currently one of the main drawbacks preventing wider industrial adoption of MAM. This work analyses the current possibilities and limitations of MAM for plastic injection moulding tool applications, demonstrating the...
Article
Full-text available
Laser-based powder bed fusion of 300-grade maraging steel allows the production of parts with a high hardness, which improves the service life and wear resistance of tooling or mould insert produced from this material. The material typically consists of a martensitic matrix material, with retained austenite and nano-precipitation. The transformatio...

Article
Full-text available
This paper presents a concept for an integrated process chain for tooling production based on metal additive manufacturing. The proposed approach aims at taking advantage of a fully digitized production line, describing the main steps for the synergetic integration of the manufacturing assets. The production line entails digital infrastructure that...
Chapter
Full-text available
Additive Manufacturing (AM) technologies have recently gained significance amongst industries as well as everyday consumers. This is largely due to the benefits that they offer in terms of design freedom, lead-time reduction, mass-customization as well as potential sustainability improvements due to efficiency in resource usage. However, convention...
Article
Full-text available
Due to the layer-by-layer nature of the process, parts produced by laser-based powder bed fusion (LPBF) have high residual stresses, causing excessive deformations. To avoid this, parts are often post-processed by subjecting them to specially designed heat treatment cycles before or after their removal from the base plate. In order to investigate t...
Article
Full-text available
Numerous challenges of additive manufacturing (AM) are tackled in the European Horizon 2020 project PAM^2 by studying and linking every step of the AM process cycle. For example, PAM^2 researchers from the design, processing and application side have collaborated in this work to optimise the manufacturability of metal AM parts using an improved Top...
Poster
Full-text available
This work presents the redesign of an injection molding metal insert to be prototyped by the Laser Powder Bed Fusion (LPBF) process. The case study has been topology optimized to minimize its total mass while keeping the maximum von Mises stress and maximum displacement under load condition below chosen thresholds. Particular attention has been giv...
Conference Paper
Full-text available
Additive manufacturing refers to the group of new manufacturing methods where parts are built layer by layer starting from a digital file. Using these technologies, it is possible to produce parts with an incomparable design freedom with, potentially, any material. The quality of the built products depend mainly on the machine capabilities, the qua...

This paper focuses on the influence that additively manufactured mould components have on the final quality of injection moulded parts. It will be presented a method that allow such an evaluation and the results obtained with maraging steel additively manufactured samples whose surfaces have been replicated with ABS in a the injection moulding proc...
Conference Paper

PAM^2, which stands for Precision Additive Metal Manufacturing, is a European MSCA project in which 10 beneficiaries and 2 partners collaborate on improving the precision of metal Additive Manufacturing. Within this project, research is done for each process stage of AM, going from the design stage to modelling, fabricating, measuring and assessmen...
Conference Paper
Full-text available
This paper focuses on a new methodology for conducting a comprehensive benchmarking of Additive Manufacturing (AM) technologies. The quality of the built products using AM strongly depends on the machine capabilities, and it is thus essential to develop a proper benchmarking design that would allow their comparative evaluation. The benchmarking pre...

Article
Powder bed additive manufacturing technologies gained much attention in past years not only thanks to design freedom but also because of the peculiar microstructures and mechanical properties that can be obtained thanks to the extremely high cooling rate. However the phenomena that arise during the laser scanning are not yet deeply understood. In t...
Conference Paper
Metal additive manufacturing (AM) is a class of innovative production technologies that allows the production of metal components layer by layer directly from a Computer Aided Design (CAD) model. The AM process of aluminium and aluminium alloys gained much interest in past years especially thanks to the high geometrical freedom, the peculiar micros...

Project
Definition of an integrated and process chain chain for production of moulds for injection moulding based on metal additive manufacturing (in particular selective laser melting). Identification of the industry 4.0 tools required and their implementation in a real industrial environment (e.g. process monitoring systems and process chain simulations).
Project
The overall objective of PAM^2 is to ensure the availability of high precision Additive Manufacturing processes and (computational) design procedures. Detailed objectives to reach this overall goal are: 1. to develop advanced (computational) design tools, enabling competitive designs, better use of AM possibilities against minimal design costs and reduced time-to-market 2. to develop better modelling tools for first-time-right processing 3. to optimise selective laser melting process strategies for improved part precision and feature accuracy 4. to understand the link between post-process metrology and in process observations, creating the basis for in-process quality control and process stability 5. to develop innovative in-process and post-process techniques to reduce or remove roughness, porosity and internal stresses and to improve dimensional accuracy and mechanical properties See also: https://www.pam2.eu
