text: 'New technologies and materials carry significant potential for sustainable
production and use of products. As an example, Additive Manufacturing technologies
and materials promise lightweight design and energy efficient use of parts. Exhausting
the full potential requires: a) consideration of uncertainties with respect to
future capabilities, and b) upgradeable design guidelines to cover advancements
consistently. The proposed approach merges concepts of Design-for-X with foresight
algorithms of Scenario-Technique to derive actionable knowledge. It is validated
by an application in the field of Additive Manufacturing, namely Metal Fused Deposition
Modelling. Engineers benefit from the intuitive access to heterogeneous types
of sustainability related information.'

text: The high flammability of components manufactured by laser sintering (LS) using
standard polyamide 12 (PA12) powder still severely restricts their use in industries
such as electronics, aviation, and transportation. A key factor for the further
establishment of LS is the expansion of the material portfolio with, for example,
refreshable and halogen-free flame-retardant (FR) powder materials. Accordingly,
various halogen-free FRs are investigated in this work and evaluated with respect
to their use in LS. First, their decomposition behavior and mode of action are
examined. Subsequently, the additives are dry blended with PA12 to investigate
properties relevant for LS, such as particle morphology, thermal behavior and
melt viscosity. Afterwards, test specimens for UL94 vertical flame-retardancy
tests are produced by processing the dry blends on an EOS P3 LS system. Finally,
the process stability of the process-aged powder blends is investigated by again
examining the thermal behavior and melt viscosity.

text: 'Polymer composites represent the industry standard in injection molding for
the production of plastic components with increased requirements in terms of heat
resistance and stiffness. In the field of laser sintering (LS), these materials
are less common so far. In order to extend the available material variety for
the LS process, new ceramic-filled Polyamide 613 powders are investigated within
the scope of this work. Here, the resulting properties from two different powder
production methods are compared. One filled powder is produced by dry blending
and the other powder with the same filler and filling ratio is produced by encapsulating
the filler particles inside the polymer particles within the dissolution-precipitation
process. It was found that encapsulating the filler particles can provide certain
benefits for the processability, for example an improved powder flowability or
better filler dispersion. However, encapsulating the filler also alters the thermal
properties of the precipitated powder. '

text: To ensure uniform documentation of support structure information, a concept
is presented that enables a standardized depiction of support structures in technical
drawings based on ISO 128-3. To this end, requirements for a uniform depiction
are defined and a procedure for drawing entry is presented. The drawing entry
should contain all production-relevant support structure information. The standardized
documentation of support structure information in technical drawings is intended
to ensure a simple, clear and safe exchange of information between business units
or different companies along the value chain. As a result a possible drawing entry
of support structures was developed. To distinguish between different support
structure types, a standardized depiction of geometrical information in a specification
field is shown. The specification field gives a detailed description of the support
structure type, the geometry as well as the connection to the part and the building
platform. Also uncommon support types like lattice structures or CAD based support
structures can be implemented. To ensure the usability the depiction is editable
and extendable.

text: "Die additive Fertigung bietet die Möglichkeit, digitale Prototypen dank der\r\nBesonderheit
der werkzeuglosen Fertigung schnellstmöglich in reale Strukturen\r\numzusetzen.
Dieses Verfahren kann jedoch nur dann mit optimaler Geschwindigkeit\r\ngenutzt
werden, wenn Engpässe wirksam vermieden werden können. Einer dieser\r\nEngpässe
ist der Konstruktionsprozess. Gerade im Bereich der additiven Fertigung\r\nsind
in letzter Zeit immer leistungsfähigere Softwarelösungen erschienen, die das\r\nDesign
für die additive Fertigung, einschließlich der meisten Computer-Aided-Design\r\n(CAD)-Aufgaben,
beschleunigen. In vielen Bereichen wird daher bereits versucht, so\r\nviele Schritte
wie möglich zu automatisieren, nicht selten unter Verwendung\r\nneuronaler Netze
und künstlicher Intelligenz. Dieser Beitrag zeigt am Beispiel einer\r\nautomatisierten
Strukturoptimierung eines Stuhls, warum das Nutzen neuronaler\r\nNetze im Konstruktionsprozess
sinnvoll ist, um die Bereiche der konventionellen\r\nTopologieoptimierung und
des Generative Design weiter zu verknüpfen und somit die\r\nProduktentwicklungszeit
zu reduzieren."

text: "Additive manufacturing, e.g. by laser powder bed fusion (LPBF), is very attractive
for lightweight constructions, as complex and stress-optimised structures integrating
multiple functions can be produced within one process. Unfortunately, high strength
AlZnMgCu alloys tend to hot cracking during LPBF\r\nand thus have not so far been
applicable. In this work the melting and solidification behaviour of\r\nAlZnMgCu
alloy powder variants with particle surface inoculation was analysed by Differential
Fast\r\nScanning Calorimetry. The aim is to establish a method that makes it possible
to assess powder modifications in terms of their suitability for LPBF on a laboratory
scale requiring only small amounts of powder.\r\nTherefore, solidification undercooling
is evaluated at cooling rates relevant for LPBF. A method for the\r\ntemperature
correction and normalisation of the DFSC results is proposed. Two ways of powder
modification were tested for the powder particles surface inoculation by titanium
carbide (TiC) nanoparticles:\r\nvia wet-chemical deposition and via mechanical
mixing.\r\nA low undercooling from DFSC correlates with a low number of cracks
of LPBF-manufactured cubes. It\r\nappears that a reduced undercooling combined
with reduced solidification onset scatter indicates the\r\npossibility of crack-free
LPBF of alloys that otherwise tend to hot cracking."

text: "Die additive Fertigung mittels Laser Powderbed Fusion Verfahren (L-PBF) von
Metallen wird zunehmend genutzt, um Funktionsbauteile endkonturnah zu fertigen.
Die in der vor-liegenden Arbeit untersuchte Parameter- und Prozessoptimierung
liefert einen Beitrag zur wirtschaftlichen Nutzung des L-PBF und zeigt, dass höhere
Aufbauraten bei der ganzheit-lichen Betrachtung des Prozesses realisierbar sind.\r\nDie
Parameter- und Prozessoptimierung erfordert eine Untersuchung des Einflusses der
Fertigungs- und Nachbearbeitungsparameter auf das erzeugte Volumen sowie auf die
Mikrostruktur und die resultierenden Materialeigenschaften. Das Ziel der vorliegenden
Arbeit ist die Entwicklung einer optimierten Prozessführung mit abschließender
Bewer-tung der Wirtschaftlichkeit. Mit dem entwickelten Gesamtprozess wird eine
um den Faktor 1,6 höhere Aufbaurate erzielt. Des Weiteren wird die Methodik zur
Erarbeitung des opti-mierten Prozessfensters beschrieben, sodass die Herangehensweise
auf weitere Werk-stoffe angewendet werden kann. Die mechanischen Eigenschaften
werden für den stati-schen und dynamischen Lastfall untersucht und mit der Mikrostruktur
korreliert. Abschlie-ßend wird die Prozessoptimierung zur Fertigung eines Demonstrators
eingesetzt und wirtschaftlich validiert. Die Ergebnisse zeigen, dass durch das
hier angewendete Vorge-hen eine Prozesszeitreduktion von 22,5% und eine Kostenreduktion
von 11% realisiert werden kann."

text: Polymer Laser Sintering (LS) is one of the most used Additive Manufacturing
(AM) technologies for the tool-less production of polymer parts. The raw material
is a polymer powder which is melted layerwise by the use of laser energy. Especially
for the production of single parts, small series, individualized and complex structures,
the technology is yet established in few branches. However, inhomogeneous and
hardly controllable thermal effects during manufacturing limit the build reproducibility.
The present work focuses on temperatures within so-called part cakes, their time
dependency and their influence on process quality. Therefore, a temperature measurement
system is implemented into a commercial laser sintering machine. Based on the
experimental data a model to simulate heat transfer within part cakes is set up.
Individual thermal histories during processing are successfully correlated with
position dependent powder ageing effects. Another focus is on the analysis of
a recycling optimized material. First results of correlations between thermal
histories and part properties are shown in order to provide an outlook to further
research. The data and knowledge gained through this work can be used to understand
thermal effects in greater depth and to increase the process quality via optimizations.
