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: 'Laser Beam Melting (LBM) is an Additive Manufacturing (AM) process on the
threshold of serial production. Therefore, LBM has to overcome different problems
such as a low productivity and minor economic efficiency. Support structures are
essential for LBM; however, these structures contribute to the mentioned topics,
because their removal is time consuming and cost intensive. To enable design engineers
and operators to increase the efficiency of LBM, design guidelinesfor support
structures suitable for post-processing are developed. For this purpose, the effect
of different design parameters on various evaluation criteria is considered. Suitability
for post-processing can be evaluated in terms of cost, quality and time. Therefore,
test specimens are built and parameter impacts on material consumption as well
as the post-processing time is examined. Furthermore, the roughness of the parts
is analyzed and used as an indicator for the removability of the support structure.
In addition, warpage is measured and the impact of the parameters on this criterion
is examined. Based on the results, suitable design guidelines and hints for support
structures are developed in order to reduce time and costs during manufacturing
and post-processing. '

text: Additive Manufacturing (AM) processes generate plastic or metal parts layer-by-layer
without using formative tools. The resulting advantages highlight the capability
of AM to become an inherent part within the product development. However, process
specific challenges such as a high surface roughness, the stair-stepping effect
or geometrical deviations inhibit the industrial establishment. Thus, additively
manufactured parts often need to be post-processed using established manufacturing
processes. Many process parameters and geometrical factors influence the manufacturing
accuracy in AM which can lead to large deviations and high scatterings. Published
results concerning these deviations are also difficult to compare, because they
are based on several geometries that are manufactured using different processes,
materials and machine settings. It is emphasized that reliable tolerances for
AM are difficult to define in standards. Within this investigation, a uniform
method was developed regarding relevant test specimens to examine geometrical
deviations for Laser Beam Melting (LBM), Fused Deposition Modeling (FDM) and Selective
Laser Sintering (SLS) in order to derive geometrical tolerance values. The manufactured
test specimens were measured using tactile and optical systems to examine the
occurring geometrical deviations. The results show possible geometrical tolerance
values that were classified according to the international standard DIN EN ISO
286-1.

text: 'Requirement changes are a major cause for project failure. A systematic approach
to manage those changes from the very beginning should be an in-tegral part of
each development project. Although this is accepted in both sci-ence and industry,
there is no adequate approach to tackle the issue, especially in the context of
interdisciplinary systems. In this paper, a secondary analysis is done to identify
all information that is necessary to manage those changes efficiently. The demanded
information is pictured in a reference model and then mapped with the capabilities
of existing approaches. Based on this, research gaps are identified and used to
guide future research efforts. '

text: Due to the great popularity of the Fused Deposition Modeling (FDM) process,
the material market is growing. In particular, processing of high-temperature
materials such as PEEK is demanding. The aim of the investigations is to test
different PEEK materials regarding their processability in the FDM process. An
unreinforced PEEK, a thermally conductive PEEK as well as a carbon fiber reinforced
PEEK are investigated. The processability is assessed with the help of the weld
seam strength. The assessment of the weld seam strength is carried out by building
tests. For this purpose, a special method developed at the DMRC is used. In addition,
a welding width factor between the strands deposited on each other is calculated
and compared. Finally, a welding factor is determined to enable the comparison
between the different materials. With this procedure, the influence of varying
nozzle and build chamber temperatures on the achievable weld seam strengths is
evaluated.

text: Plastic freeforming (PF) is an additive-manufacturing process for producing
three-dimensional plastic parts based on 3D CAD data by applying plastic droplets
in layers. This process is used to produce customer-specific and complex geometries
(prototypes and small series) on organic sheets. A comparable serial process is
the injection of a second component onto organic sheets by injection molding.
A sufficient bond between the PF structure and the organic sheets is of particular
importance for each application. If this is not guaranteed, the composite system
cannot withstand the mechanical load and fails. The force exerted on the system
can no longer be transmitted between the PF structure and the organic sheet. The
organic sheet is made of glass fiber-reinforced polypropylene (PP). The connection
between the organic sheet and the PF structure is achieved by welding the molten
polymer droplets and the surface of the organic sheet. The PF structures are made
of PP to ensure sufficient compatibility with regard to the weldability of the
components. The processing of PP in the PF process is a challenge because PP is
a semicrystalline material. The shrinkage of semi-crystalline materials is significantly
higher compared to amorphous materials. Due to the layered structure of the components,
the shrinkage of the individual layers results in undesired warpage. The adhesive
strength between the organic sheet and the PF structure is investigated by determining
the bending strength in the 3-point bending test. The investigations include an
optimization of the process parameters to maximize the adhesive strength. The
experimental investigations show that an increase of the nozzle and build chamber
temperature leads to a higher adhesive strength. In further investigations, the
temperature of the nozzle shows no significant influence on the surface temperature
despite the expected heat radiation. The surface temperature is almost only dependent
on the temperature of the build chamber.

text: The mechanical properties of thin-walled plastic components are limited. One
approach to improve the strength or stiffness of these components is to reinforce
the thin-walled areas with an individually adapted Fused Deposition Modeling structure.
Fused Deposition Modeling (FDM) is one of the most commonly used additive manufacturing
processes. This process is characterized by the deposition of a fused, thermoplastic
filament. Depending on the form of the reinforcement structure, the resulting
hybrid structure should show higher strength or stiffness. The objective of the
project is to determine constructive design and process guidelines for FDM structures.
The FDM structure is to be used as a partial reinforcement for lightweight components
and be adapted to the respective load conditions. Because of the lightweight application,
the FDM structure should also have the lowest possible weight. The optimization
of the FDM parts for different load cases is realized by adapting the design parameters.
These parameters influence the layer generation and therefore also the inner structure
of the FDM parts. In preliminary studies, the manufacturing restrictions of the
FDM process are defined. The specimens are manufactured based on the Design of
Experiments. To determine the static strength properties, different tests (tensile,
compression, flexural, torsion and impact) are carried out. The investigations
show that the filling strategy affects the mechanical properties. As a result
of the investigations, design and process guidelines for the FDM structures are
established according to the load conditions.

text: Additive manufacturing processes, like the Fused Deposition Modeling (FDM)
process, do not need product-specific tools and create parts directly from the
CAD data. In the FDM process, the semi-finished product, a wire of a thermoplastic
polymer, is melted and forced through a nozzle. The continuous positioning of
this nozzle allows the polymer to weld together strand by strand and layer by
layer to produce a component. Because no mold is used in the FDM process, no holding
pressure can be generated as in injection molding processes, in which the holding
pressure is used to minimize the shrinkage and warpage of the part. In the FDM
process, the part is generated in an ambient pressure environment. Each strand
cools down and shrinks separately. This causes residual stresses in the part that
can lead to major warpage and a complete stoppage of the process. This is the
main reason why the material selection in the FDM process is restricted in comparison
to conventional polymer processing technologies. In this paper, the warpage of
different polymers is quantified as a criterion for evaluating the processability
of polymers in the FDM process. Due to the process principle, the part properties
in the FDM process are mainly influenced by the machine quality and the data processing,
so that it is difficult to test a material for FDM independently of the machine
and the data processing. Considering these influences, a custom-built specimen
is created to test and quantify the warpage of different types of blended and
reinforced polyamide 6. Considering the experimentally investigated warpage, the
materials can be evaluated and the warpage can be related to the shrinkage investigated
in pvT measurements. This procedure allows the machine- and process-independent
rating of the processability in terms of warpage for different materials. Alongside
other criteria, this is a necessary step to develop new materials with good processability
in the FDM process.

text: Das Fused Deposition Modeling (FDM) ist ein etabliertes additives Fertigungsverfahren
zur Her-stellung von thermoplastischen Kunststoffbauteilen. In dem vorliegenden
Beitrag sind FDM-Verstärkungsstrukturen aus dem Material Ultem 9085 dynamischen
Langzeituntersuchungen un-terzogen worden. Dabei wurde die innere Struktur der
Probekörper über eine Parametervariation verändert, sodass anschließend die signifikanten
Einflussfaktoren auf die Langzeitfestigkeit un-ter dynamischer Belastung identifiziert
und analysiert werden konnten. Mit dieser Vorgehens-weise sollte gleichzeitig
eine Optimierung der FDM-Verstärkungsstrukturen hinsichtlich der dy-namischen
Langzeiteigenschaften bei Biege- und Druckbelastungen vorgenommen werden. Des
Weiteren sind anhand der Probekörper die auftretenden Bruch- und Rissausbreitungsmechanis-men
analysiert worden. Anhand der ermittelten Wöhlerkurven kann die Lebensdauer unter
dy-namischer Belastung abgeschätzt werden. Außerdem zeigen die Untersuchungen,
dass Fehlstel-len durch eine hohe Strangbreite und Überfüllungen im Bauteil für
Schwachstellen in den FDM-Verstärkungsstrukturen sorgen, an denen Risse bei Druckbelastung
entstanden sind und sich dadurch schneller ausbreiten konnten.

text: The Arburg Plastic Freeforming (APF) is an additive manufacturing process
that allows three-dimensional, thermoplastic components to be produced in layer
by layer. The components are generated by depositing fine, molten plastic droplets.
One of the main advantages of the APF process is the open machine control. Thus,
the process parameters can be adapted and optimized for the individual applications.
The optimization is carried out on the basis of a variation of the process parameters
using a statistical design of experiments. Relevant process parameters are the
layer thickness, the form factor, the raster and delta angle as well as the overlap
between the contour and the filling of a layer. In addition, the nozzle and build
chamber temperatures are varied. Using this procedure, the effects of the influencing
parameters on the mechanical properties and the interactions between the influencing
parameters are analyzed and converted into mathematical models. On the basis of
the results and the models, guidelines will be developed to assist the user of
APF technology in the systematic process configuration for their own applications.
The material used is ABS, one of the most frequently used amorphous thermoplastics
in additive manufacturing. The mechanical properties are determined on the basis
of tensile tests and the characteristic values tensile strength, elongation at
break and Young's modulus. The results should show the performance of the APF
technology in regard to the mechanical properties.

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: According to ISO / ASTM 52900, additive manufacturing (AM) is defined as "the
process of joining materials to make parts from 3D model data, usually layer upon
layer, as opposed to conventional manufacturing including subtractive manufacturing
technologies and formative manufacturing methodologies” [1]. This results in significant
advantages over conventional manufacturing methodologies, such as the production
of topologically optimized, complex structures, lower material consumption or
shorter product development cycles. In order to be able to use these advantages,
the possibilities and restrictions of the processes must be known. In particular,
selective laser beam melting (SLM), in which a powdery metallic starting material
is melted by means of a laser, requires a sound understanding of the process.
For this purpose, design guidelines have been presented in various scientific
papers. These design guidelines help to design a component in such a way that
it can be manufactured successfully using additive manufacturing. These so-called
“AMsuitable design guidelines” can be found among others at Adam, Kranz and Thomas
[2,3,4,5]. In contrast to established manufacturing processes, the post-processing
of additive components is divided into two steps. First, the AM immanent post
processing, such as the removing of the component from the building platform or
the removing of the remaining powder. These post-processing steps are in the following
referred to “post-processing”. Secondly, the subsequent post-processing steps
to improve the component properties, such as milling and turning or a stress-relief
annealing. These are referred to as “finishing” and form the focus of this paper.
With regard to a successful finishing of additively manufactured components, design
guidelines must be taken into account that consider the finishing inherent restrictions
and possibilities. In the following, these design guidelines are referred to “finishing
suitable”. They can deviate significantly from those of conventionally manufactured
components in the case of additively manufactured components. Although there are
some investigations that deal with the post-processing of additively manufactured
components [6,7], there are hardly any design guidelines that are suitable for
finishing [8]. Therefore, knowledge about the finishing of additively manufactured
components is based on experimental experience rather than on scientific knowledge.
For this reason, design guidelines for a finishing suitable design must be methodically
determined and quantified. These quantified design guidelines can be used for
an automated design check on complex components like topology optimized geometries.
