text: "Abstract\r\n The phenomenon
of entanglement is the basis of quantum information and quantum communication
processes. Entangled systems with a large number of photons are of great interest
at present because they provide a platform for streaming technologies based on
photonics. In this paper we present a device which operates with four-photons
and based on the Hong–Ou–Mandel interference. The presented device allows to maximize
the degree of spatial entanglement and generate the highly entangled four-dimensional
Bell states. Furthermore, the use of the interferometer in different regimes leads
to fast interference fringes in the coincidence probability with period of oscillations
twice smaller than the pump wavelength. We have a good agreement between theoretical
simulations and experimental results."

text: 'Die Additiven Fertigungsverfahren stehen im Übergang zur stärken industriellen
Anwendung. Weit mehr als die Hälfte aller mittelständischen Unternehmen sehen
die Technologien zukünftig als etablierte Verfahren oder gar Schlüsseltechnologien
im eigenen Unter-nehmen. Dass der Schritt zur industriellen Nutzung bislang allerdings
nicht erfolgt ist, liegt oft am Prozess der Technologieintegration selbst. Unternehmen
gelingt es nicht, die fehlende Expertise aufzubauen, die Akzeptanz gegenüber der
Additiven Fertigung erfolg-reich zu stärken und die hohen Kosten zu beherrschen.
Diese Problematik bestätigen neben Studien des Industriearbeitskreises Light Alliance
und der National Association of Manufacturers (USA) auch der Richtungswandel der
Forschungsförderung des Bundesministeriums für Bildung und Forschung. Vor diesem
Hintergrund gilt es, die auftretenden Hindernisse der Technologieintegration differenziert
zu betrachten und erforderliche spezifische Lösungsmethoden in einzelnen Handlungsfeldern
abzuleiten. Für diese Handlungsfelder sind anschließend Vorgehensmodelle zu entwickeln,
wodurch Hemmnisse wie die hohen Kosten gelöst werden sollen. Die resultierenden
Modelle sind in eine Gesamtsystematik zu überführen, welche Unternehmen unter
Berücksichtigung der bestehenden Unternehmensprozesse und -strukturen bei der
prozessbasierten Technologieintegration der Additiven Fertigung im Unternehmen
unterstützt. Die Anwendbarkeit des Verfahrens wird durch eine industrielle Fallstudie
untermauert und validiert. '

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: 'Produktpiraterie und damit einhergehende Imitationen gefährden neben dem
wirtschaftlichen Erfolg der Unternehmen am Beispiel des deutschen Maschinen- und
Anlagenbaus auch den sicheren Betrieb von Anlagen und somit von Leib und Leben.
Im Kontext der Produktpiraterie werden Additive Fertigungsverfahren durch den
global möglichen, nahezu unkontrollierbaren Datenaustausch häufig als Treibertechnologie
dargestellt. Dem entgegenstehend werden die Additiven Fertigungsverfahren aber
in der Literatur auch sehr undifferenziert als mögliche Produktschutzmaßnahme
aufgeführt. Darauf deuten auch die Ergebnisse einer Studie des Verbands Deutscher
Maschinen- und Anlagenbau e.V., der auf das Reverse Engineering als relevanteste
Informationsquelle für Imitatoren verweist. Vor diesem Hintergrund gilt es, die
Motivation und das Vorgehen der Imitatoren zu untersuchen und den technischen
und wirtschaftlichen Potentialen der Additiven Fertigungsverfahren differenziert
gegenüberzustellen. Darauf aufbauend ist ein systematisches Vorgehen zum präventiven
Produktschutz durch Additive Fertigungsverfahren zu entwickeln. Die resultierende
Systematik führt die Unternehmen unter Berücksichtigung des präventiven Produktschutzes
schrittweise durch die Produktentstehung und unterstützt bei der Identifikation
schützenswerter Funktionen sowie der Auswahl und Implementierung geeigneter additiver
Schutzpotentiale. Die Anwendbarkeit des Verfahrens wird durch eine industrielle
Fallstudie untermauert und validiert. '

text: "Die additive Fertigung als werkzeugloses Fertigungsverfahren bietet zahlreiche
neue Möglichkeiten in der technischen Produktgestaltung. Insbesondere auf Leichtbau
optimierte, hochkomplexe Strukturen lassen sich hiermit wirtschaftlich fertigen.
Die Bauteile müssen jedoch auch speziell auf die Verfahren angepasst sein, um
sicher, fehlerfrei und kostengünstig produziert werden zu können. Mit konventionellen
Konstruktionsverfahren sind solche Strukturen nur schwer erzeugbar.\r\nIm Rahmen
dieser Arbeit wird daher eine Methodik zur intelligenten Optimierung von Produktgeometrien,
angepasst an die additive Fertigung, entwickelt. Dies beinhaltet die automatische
Erzeugung von anwendungsfallspezifisch optimierten Geometrien sowie deren Überführung
in Datenstrukturen, welche in konventionellen CAD-Systemen nutzbar sind. Als grundlegendes
Werkzeug wird dabei die Topologieoptimierung verwendet, welche hochaufgelöst durchgeführt
und im Anschluss mit hoher Qualität geglättet und weiterverarbeitet werden muss.
Hierzu wurde ein durchgängiger voxelbasierter Ansatz gefunden, der auch die Anpassung
der Geometrien an die additive Fertigung erlaubt. Die Entwicklung und Funktionalität
des Ansatzes wird auf Basis mehrerer Beispielbauteile gezeigt. Das Ergebnis der
Optimierungen sind hochkomplexe, im Detail optimierte und an die additive Fertigung
angepasste Strukturen. "

text: Industrieunternehmen versuchen zunehmend das technologische und ökonomische
Potential des schichtbasierten Fertigungsansatzes der additiven Fertigung vorteilhaft
für sich einzusetzen. Problematisch ist dabei jedoch die geringe Erfahrung der
Unternehmen mit der additiven Fertigung und ihren Besonderheiten. Ein Vergleich
mit anderen Fertigungsverfahren muss dabei über eine reine Kostenkalkulation hinausgehen,
um zusätzliche Potentiale und Einschränkungen abwägen zu können. Die vorliegende
Arbeit gibt daher einen Überblick über die wesentlichen Einflussfaktoren Kosten,
Zeit und Qualität und es wird auf dieser Basis eine Entscheidungsunterstützung
entwickelt, die bei der Identifizierung vorteilhafter Einsatzmöglichkeiten für
die additive Fertigung hilft. Da die additive Technologie auch signifikante Änderungen
im Bereich der Supply Chain erzielen kann, liegt der Fokus des Einsatzgebietes
auf der zeitkritischen Ersatzteilversorgung, betrachtet am Beispiel der Luftfahrtindustrie.
In diesem Kontext ist es Ziel und Zweck der Arbeit, die oftmals isoliert betrachteten
drei Bereiche Kosten, Zeit und Qualität zu einem ganzheitlichen Vergleich zu kombinieren.
Die entwickelte Entscheidungsunterstützung ist dabei auf Basis einer funktionserweiterten
Tabellenkalkulation als Demonstrator umgesetzt worden.
