text: AbstractThis paper presents the results of
an interlaboratory study of the rheological properties of cement paste and ultrasound
gel as reference substance. The goal was to quantify the comparability and reproducibility
of measurements of the Bingham parameters yield stress and plastic viscosity when
measured on one specific paste composition and one particular ultrasound gel in
different laboratories using different rheometers and measurement geometries.
The procedures for both in preparing the cement paste and carrying out the rheological
measurements on cement paste and ultrasound gel were carefully defined for all
of the study’s participants. Different conversion schemes for comparing the results
obtained with the different measurement setups are presented here and critically
discussed. The procedure proposed in this paper ensured a reasonable comparability
of the results with a coefficient of variation for the yield stress of 27% and
for the plastic viscosity of 24%, despite the individual measurement series’ having
been performed in different labs with different rheometers and measurement geometries.

text: Since suspensions (e.g., in food, cement, or cosmetics industries)
tend to show wall slip, the application of structured measuring surfaces in rheometers
is widespread. Usually, for parallel-plate geometries, the tip-to-tip distance
is used for calculation of absolute rheological values, which implies that there
is no flow behind this distance. However, several studies show that this is not
true. Therefore, the measuring gap needs to be corrected by adding the effective
gap extension δ to the prescribed gap height H in order to obtain
absolute rheological properties. In this paper, we determine the effective gap
extension δ for different structures and fluids (Newtonian, shear thinning,
and model suspensions that can be adjusted to the behavior of real fluids) and
compare the corrected values to reference data. We observe that for Newtonian
fluids a gap- and material-independent correction function can be derived for
every measuring system, which is also applicable to suspensions, but not to shear
thinning fluids. Since this relation appears to be mainly dependent on the characteristics
of flow behaviour, we show that the calibration of structured measuring systems
is possible with Newtonian fluids and then can be transferred to suspensions up
to a certain particle content.

text: The influence of latent heat storage elements on the cooling performance and
the temperature rise time of household refrigerating appliances is studied experimentally
in the context of the “new global refriger- ator standard”IEC 62552:2015. In addition
to the daily energy consumption, this international standard- ization introduced
performance tests for cooling capacity and temperature rise time. While the cooling
capacity has long been anchored in various test procedures of consumer organizations,
the temperature rise time, which has only been tested on freezers so far, will
be a decisive factor in the future. Moreover, the need for so-called "smart appliances"
that may balance power consumption is increasing since such devices may compensate
the volatility of renewable energies and thus stabilize the power grid. Against
this background, eight commercial household refrigerators and refrigerator-freezers
are equipped with polymer-bound phase change materials (PCM) and their performance
is determined under the new stan- dard test conditions. The results show that
the introduction of PCM increases the cooling capacity by up to 33 % and also
increases the temperature rise time by up to 145 %, without affecting power consump-
tion, as compared to the unmodified refrigeration appliances.

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.

text: "Stand der Technik beim Lasersintern von Kunststoffen (SLS) ist die Fertigung
von Prototypen aus z.B. Polyamid 12. Die industrielle Serienproduktion mittels
SLS erfordert die Qualifizierung von produktspezifischen Materialien. Kernthema
dieser Arbeit ist die Verarbeitung von neuen Kunststoffen.\r\nHierzu wird eine
optimierte Anlagentechnik entwickelt. Die Verarbeitung von schlecht rieselfähigen
Pulvern wird durch ein innovatives Beschichtungssystem ermöglicht. Durch eine
zwölf Zonen Heizungsregelung erfolgt die Pulvervorwärmung in der erforderlichen
Präzision. Zudem ermöglicht ein variabler Laserspot eine Belichtung mit hoher
Detailauflösung bei gleichzeitig hoher Aufbaurate.\r\nDer Energieeintrag im SLS
Prozess und die Belichtung mit variablem Laserspotdurchmesser werden theoretisch
betrachtet und mittels Computertomographie experimentell untersucht.\r\nAbschließend
wird eine Systematik zur Identifizierung von Prozessparameter für die Verarbeitung
neuer Materialien erarbeitet und exemplarisch wird das neue Material Polyamid
613 prozessiert."

text: Zuverlässige, wiederholbare Bauteileigenschaften sind unabdingbar um das Herstellungsverfahren
Polymer Lasersintern im industriellen Prozess-Portfolio vieler Firmen aufnehmen
zu können. Einige Unternehmen und Institute haben sich daher in jüngster Zeit
mit dem Thema der reproduzierbaren Bauteileigenschaften beschäftigt. Mit der hier
vorgestellten und angewandten Methodik wird nicht nur der Prozessablauf vom Bauteil
bis zu Nachbearbeitung betrachtet, sondern auch die Maschinenperformance in einem
Ringversuch und über einen längeren Zeitraum geprüft. Rückgrat dieser Untersuchung
bildet hierbei der aus der Six Sigma Lehre stammende DMAIC (Define - Measure -
Analyse - Improve - Control) Verbesserungszyklus. Hierfür wird ein Standard-Prozess
definiert. Diesem folgend werden die für die Industrie oder den Anwender interessanten
Messungen aufgenommen und analysiert. Anschließend wird der Prozess sowie die
Messmethodik optimiert und auch Kontrollmethoden definiert. Für die Anwendung
der entwickelten Methodik wird exemplarisch der Maschinentyp EOS P396 mit PA2200
untersucht. Daten für die Bestimmung der Mechanik, der Optik und der Haptik sowie
für die Dimensionen und die Bauteildichte werden als Qualitätskriterium aufgenommen
und über einen längeren Zeitraum analysiert. Weiteres Ziel ist es, den Messaufwand
zu reduzieren und die Qualitätssicherung im Serienbtrieb zu gewährleisten.

text: Structural parts for aviation have very high demands on the development and
production process. Therefore, the entire process must be considered in order
to produce high-quality AM metal parts. In this case study, a conventional part
was selected to be optimized for AM. The process presented includes component
selection, design improvement with a novel approach for topology optimization
based on the AMendate algorithm as basis of MSC Apex Generative Design,component
production on a SLM 250 HL and post-processing including heat treatment and surface
smoothing. With the topology optimization a weight reduction of ~60 % could be
realized, whereby the stress distribution is more homogeneous. Furthermore, the
challenges of support optimization and post-processing have to be addressed, in
order to produce competitive parts.

text: Function integration is a key issue for an efficient and economic usage of
Additive Manufacturing. An efficient heat transfer by topology optimized structures
is a rarely considered approach which will be outlined with an exemplary electronic
housing which has been newly designed. A commercial projector unit, whose electrical
components in total produce 38 W, shall be integrated in the closed housing and
passively cooled by natural convection. Topology optimized structures shall be
generated in the inner part of the housing to transfer the heat homogenously from
the projector components to the housing wall while simultaneously minimizing the
mass. At the outside of the housing walls, lattice and rib structures are applied
to increase the effective surface for heat transfer by natural convection and
radiation. Furthermore, the housing geometry is optimized regarding a minimization
of support structures to reduce the post-processing effort. Finally, the housing
shall be built of AlSi10Mg by SLM.

text: The influence of selective laser sintering (SLS) parameters on PA12 part properties
is well known, but research on other materials is rare. One alternative material
is a thermoplastic elastomer (TPE) called PrimePart ST that is more elastic and
shows a distinct SLS processing behavior. It undergoes a three-dimensional temperature
distribution during the SLS process within the TPE part cake. To examine this
further, a temperature measurement system that allows temperature measurements
inside the part cake is applied to TPE in the present work. Position-dependent
temperature histories are directly correlated with the color and mechanical properties
of built parts and are in very good agreement with artificial heat treatment in
a furnace. Furthermore, it is clearly shown that the yellowish discoloration of
parts in different intensities is not only temperature dependent but also influenced
by the residual oxygen content in the process atmosphere. Nevertheless, the discoloration
has no influence on the mechanical part properties.
