text: "This paper considers the shape formation problem within the 3D hybrid model,
where a single agent with a strictly limited viewing range and the computational
capacity of a deterministic finite automaton manipulates passive tiles through
pick-up, movement, and placement actions. The goal is to reconfigure a set of
tiles into a specific shape termed an icicle. The icicle, identified as a dense,
hole-free structure, is strategically chosen to function as an intermediate shape
for more intricate shape formation tasks. It is designed for easy exploration
by a finite state agent, enabling the identification of tiles that can be lifted
without breaking connectivity. Compared to the line shape, the icicle presents
distinct advantages, including a reduced diameter and the presence of multiple
removable tiles. We propose an algorithm that transforms an arbitrary initially
connected tile structure into an icicle in \U0001D4AA(n³) steps, matching the
runtime of the line formation algorithm from prior work. Our theoretical contribution
is accompanied by an extensive experimental analysis, indicating that our algorithm
decreases the diameter of tile structures on average."

text: Motivated by the prospect of nano-robots that assist human physiological functions
at the nanoscale, we investigate the coating problem in the three-dimensional
model for hybrid programmable matter. In this model, a single agent with strictly
limited viewing range and the computational capability of a deterministic finite
automaton can act on passive tiles by picking up a tile, moving, and placing it
at some spot. The goal of the coating problem is to fill each node of some surface
graph of size n with a tile. We first solve the problem on a restricted class
of graphs with a single tile type, and then use constantly many tile types to
encode this graph in certain surface graphs capturing the surface of 3D objects.
Our algorithm requires O(n^2) steps, which is worst-case optimal compared to an
agent with global knowledge and no memory restrictions.

text: "This paper reveals the 3D character of the intermetallic layer at the aluminum–steel
interface which pops\r\nup above the original sample surface during annealing.
Popping out of the intermetallics was proven using\r\natomic force microscopy.
The phase expands out of the plane due to the exothermic formation of the Al5Fe2\r\nphase
and the feasibility of surface diffusion. Milling by a focused ion beam enabled
the comparison of the\r\nchemical composition of the surface layer with the bulk
interface, showing no difference. The growth direction\r\nis both towards aluminum
and steel — the main diffusion flux is from aluminum towards steel, and the new\r\nintermetallic
phase emerges at the steel side. The shortage of Al atoms causes a shift of the
intermetallic as a\r\nwhole towards aluminum."

text: '3D printing is a well-established technology with rapidly increasing usage
scenarios both in the industry and consumer context. The growing popularity of
3D printing has also attracted security researchers, who have analyzed possibilities
for weakening 3D models or stealing intellectual property from 3D models. We extend
these important aspects and provide the first comprehensive security analysis
of 3D printing data formats. We performed our systematic study on the example
of the 3D Manufacturing Format (3MF), which offers a large variety of features
that could lead to critical attacks. Based on 3MF’s features, we systematized
three attack goals: Data Exfiltration (dex), Denial of Service, and UI Spoofing
(uis). We achieve these goals by exploiting the complexity of 3MF, which is based
on the Open Packaging Conventions (OPC) format and uses XML to define 3D models.
In total, our analysis led to 352 tests. To create and run these tests automatically,
we implemented an open-source tool named 3MF Analyzer (tool), which helped us
evaluate 20 applications.'

text: "Die additive Fertigung bietet die Möglichkeit, digitale Prototypen dank der\r\nBesonderheit
der werkzeuglosen Fertigung schnellstmöglich in reale Strukturen\r\numzusetzen.
Dieses Verfahren kann jedoch nur dann mit optimaler Geschwindigkeit\r\ngenutzt
werden, wenn Engpässe wirksam vermieden werden können. Einer dieser\r\nEngpässe
ist der Konstruktionsprozess. Gerade im Bereich der additiven Fertigung\r\nsind
in letzter Zeit immer leistungsfähigere Softwarelösungen erschienen, die das\r\nDesign
für die additive Fertigung, einschließlich der meisten Computer-Aided-Design\r\n(CAD)-Aufgaben,
beschleunigen. In vielen Bereichen wird daher bereits versucht, so\r\nviele Schritte
wie möglich zu automatisieren, nicht selten unter Verwendung\r\nneuronaler Netze
und künstlicher Intelligenz. Dieser Beitrag zeigt am Beispiel einer\r\nautomatisierten
Strukturoptimierung eines Stuhls, warum das Nutzen neuronaler\r\nNetze im Konstruktionsprozess
sinnvoll ist, um die Bereiche der konventionellen\r\nTopologieoptimierung und
des Generative Design weiter zu verknüpfen und somit die\r\nProduktentwicklungszeit
zu reduzieren."

text: "Anwendungen von Laser-Sinter Bauteilen als Sichtteile sind aufgrund der vergleichsweise
schlechten Oberflächenqualität sehr begrenzt. In dieser Arbeit werden dreidimensionale
Kennwerte benutzt, um die Oberflächenqualität von Laser-Sinter Bauteiloberflächen
und die Einflüsse aus unterschiedlichen Bereichen der gesamten Prozesskette zu
evaluieren. Beispielsweise wurden objektive Kennwerte, mit deren Hilfe Orangenhaut
zu identifizieren ist, und Prozessparameter, die diese deutlich vermindern, gefunden.
Mittels Durchführung von haptischen Versuchen wurde das subjektive Empfinden ermittelt
und konnten zu objektiven Kennwerten korreliert werden. Eine mikroskopische Betrachtung
des flachen Oberflächenwinkels mit verschieden farbigen Pulvern zeigt neue Erkenntnisse
zum Anschmelzvorgang von Partikeln an die Schmelze. Zur nachträglichen Glättung
von Oberflächen wurden mechanische, chemische und optische Nachbehandlungsmethoden
verwendet und deren Potential aufgezeigt. Eine abschließende neuartige Simulation
der dreidimensionalen Topografie bildet die Grundlage für ein Programm zur automatischen
und funktionsgerechten Orientierung von Bauteilen, welche am Beispiel eines realen
Bauteils erfolgreich validiert wurde. Zusammengenommen zeigen die Ergebnisse,
dass die richtige Wahl von Bauorientierung und Prozessparametern entscheidend
für die Bauteilqualität ist und selbst eine aufwendige Nachbearbeitung eine ungeschickte
Wahl derer nur schwerlich ausgleichen kann.\r\n"
