text: In the laser sintering technology, the semi-crystalline polymer material is
exposed to elevated temperatures during processing, which leads to serious material
ageing for most materials. This has already been investigated intensively by various
authors. However, the ageing of the material at ambient temperatures during shelf
life has not been the focus so far. The need to analyse the shelf life can be
derived from an ecological and economic point of view. This work is focusing on
the shelf life of PA2200 (PA12). To reduce the potential influences of powder
production fluctuations, two different powder batches stored for 5.5 years and
6.5 years are investigated and compared to a reference powder produced 0.5 years
before these investigations. Multiple powder analyses and part characterisations
have been performed. A significant yellowing and molecular chain length reduction
can be derived from the measurement results. Whereas the influence on mechanical
part performance was minor, the parts built with the stored powders are more yellowish.
As it is most likely that this is due to the consumption of polyamide stabilisers,
it can be assumed that these parts will be subject to significantly faster ageing.
Therefore, it is still not recommended to use the stored powders for critical
parts or light intense and humid environments.

text: In biomedical engineering, laser powder bed fusion is an advanced manufacturing
technology, which enables, for example, the production of patient-customized implants
with complex geometries. Ti-6Al-7Nb shows promising improvements, especially regarding
biocompatibility, compared with other titanium alloys. The biocompatible features
are investigated employing cytocompatibility and antibacterial examinations on
Al2O3-blasted and untreated surfaces. The mechanical properties of additively
manufactured Ti-6Al-7Nb are evaluated in as-built and heat-treated conditions.
Recrystallization annealing (925 °C for 4 h), β annealing (1050 °C for 2 h), as
well as stress relieving (600 °C for 4 h) are applied. For microstructural investigation,
scanning and transmission electron microscopy are performed. The different microstructures
and the mechanical properties are compared. Mechanical behavior is determined
based on quasi-static tensile tests and strain-controlled low cycle fatigue tests
with total strain amplitudes εA of 0.35%, 0.5%, and 0.8%. The as-built and stress-relieved
conditions meet the mechanical demands for the tensile properties of the international
standard ISO 5832-11. Based on the Coffin–Manson–Basquin relation, fatigue strength
and ductility coefficients, as well as exponents, are determined to examine fatigue
life for the different conditions. The stress-relieved condition exhibits, overall,
the best properties regarding monotonic tensile and cyclic fatigue behavior.

text: By monitoring the recoating process within polymer laser sintering production,
it was shown that multiple powder-spread-flaws can be detected. Those groove-like
flaws are expected to be the result of agglomerates jamming between the recoater
and the last powder layer. This work is analyzing the interaction between powder-spread-flaws
and part properties, showing the influence of the recoating process on the performance
of laser sintering parts. Therefore, artificial powder-spread-flaws are applied
to the build jobs of tensile test specimens which are measured and analyzed regarding
the elongation at break, strength and fracture position. For the characteristics
of the flaws, the artificial grooves are varied in depth and width. Furthermore,
the position of the flaw is changed form mid part to close to surface areas. It
was shown, that several flaws are visible at the part surface, resulting in stress
concentration and reduced performance. But there are as well parts with flaw-layers,
which are not visible after the build process on the part. Those parts can have
significantly reduced mechanical properties as well.

text: Abstract:Since fine powders tend strongly to adhesion and agglomeration, their
processing withconventional methods is difficult or impossible. Typically, in order
to enable the handling of finepowders, chemicals are added to increase the flowability
and reduce adhesion. This contributionshows that instead of additives also vibrations
can be used to increase the flowability, to reduceadhesion and cohesion, and thus
to enable or improve processes such as precision dosing, mixing,and transport
of very fine powders. The methods for manipulating powder properties are describedin
detail and prototypes for experimental studies are presented. It is shown that
the handling of finepowders can be improved by using low-frequency, high-frequency
or a combination of low- andhigh-frequency vibration.

text: The transportation of dry fine powders is an emerging technologic task, as
in biotechnology, pharmaceu-tical and coatings industry the particle sizes of
processed powders get smaller and smaller. Fine powdersare primarily defined by
the fact that adhesive and cohesive forces outweigh the weight forces, leadingto
mostly unwanted agglomeration (clumping) and adhesion to surfaces. Thereby it
gets more difficult touse conventional conveyor systems (e.g. pneumatic or vibratory
conveyors) for transport. A rather newmethod for transporting these fine powders
is based on ultrasonic vibrations, which are used to reducefriction between powder
and substrate. Within this contribution an experimental set-up consisting of apipe,
a solenoid actuator for axial vibration and an annular piezoelectric actuator
for the high frequencyradial vibration of the pipe is described. Since amplitudes
of the radial pipe vibration should be as large aspossible to get high effects
of friction reduction, the pipe is excited to vibrate in resonance. To determinethe
optimum excitation frequency and actuator position the vibration modes and resonance
frequenciesof the pipe are calculated and measured. Results are in good accordance.
