text: The Arburg Plastic Freeforming (APF) is an additive manufacturing process
which allows the production of three-dimensional thermoplastic components in layers.
The components are produced by depositing fine, molten plastic droplets. The main
advantage of the APF is the open-parameter control of the associated machine system.
Thus, the process parameters can be optimized for individual applications. A special
and new application of the APF is the production of interconnecting porous structures.
As this is a novel approach with this manufacturing process, the general producibility
and reproducibility must first be proven. Therefore, the relevant process parameters
with an influence on the open-pored structures are identified. The volume of the
individual plastic droplets, the distance between the droplets and the layer thickness
are the three decisive influencing factors. With the use of analysis methods,
the free spaces created in the structure are described by a uniformly constructed,
interconnected pore structure. This means that the pores are interconnected in
three dimensions. Reproducibility is evaluated by repeated production and thru
the changed conditions during the manufacturing process. In addition, the multiplication
and a change of geometry are evaluated in such a way that there is no influence
on the pore size. Irregularities when depositing the first layer are caused by
unevenness of the building platform. A suitable test arrangement is set up to
determine the liquid permeability. A characteristic value is determined to describe
the permeability to liquids.

text: Arburg Plastic Freeforming (APF) is an additive manufacturing process with
which three-dimensional, thermoplastic components can be produced layer by layer.
Visual and geometrical properties are a major criterion for characterizing the
resulting component quality. The aim of this study was to investigate the influences
on visual and geometrical properties of APF components depending on process parameters.
Initially the focus was on the analysis of the shrinkage behavior of ABS-M30 (Stratasys).
On the basis of the results and an existing procedure by the machine manufacturer,
an optimized procedure for determining the scaling factors was developed to counteract
the shrinkage. With this procedure a higher dimensional accuracy of the components
can be achieved. In addition, it was investigated whether an adaption of the form
factor based on a mathematical model depending on the component geometry makes
sense. The results were transferred into manufacturing guidelines, which allow
the user of the APF-technology to optimize process parameters more efficiently.

text: "The additive manufacturing process Fused Deposition Modeling (FDM) is established
in the industry for many years. A new, similar process to FDM is the Arburg Plastic
Freeforming (APF). The main differences between both processes are the form of
the starting material (FDM: Filaments, APF: Conventional granulate) and the material
deposition during the layer formation (FDM: Melt strand, APF: fine molten droplets).\r\nSince
the two processes can be used in similar applications, the aim of this study is
to compare both processes in a holistic way. Furthermore, the advantages and disadvantages
of the processes are to be highlighted. The systematic comparison between a Stratasys
400mc and the Freeformer 200-3X is divided into the areas of component properties,
design limitations and economic efficiency. The material ABS-M30 (Stratasys) is
used in both processes. The results show comparable component properties regarding
mechanical and optical properties but also differences in design limitations and
cost efficiency.\r\n"

text: "The Arburg Plastic Freeforming (APF) is an additive manufacturing process
with which three-dimensional, thermoplastic components can be produced layer by
layer. One disadvantage of the APF is the long residence time of the molten material
in the plasticizing unit compared to conventional injection moulding. The dosing
volume is emptied very slowly due to only discharging fine plastic droplets. As
a result, long residence times can be expected, which can lead to thermal degradation
of the material.\r\nThe aim of this study was to develop a model for calculating
the residence time of the material in the APF. The residence time of the material
in the thermally critical dosing volume is predicted using software developed
in-house. The accuracy of the model could be verified by experimental investigations.
Finally, the thermal degradation of the material was investigated by analyzing
the correlation to the mechanical properties of tensile strength specimens.\r\n"

abstract:
- lang: eng
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: 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.
