  text: The process-related occurrence of varying cooling rates at different positions
    within the part cake is an important challenge regarding the part quality and
    reproducibility of the polymer laser sintering process. Temperature history dependent
    parameters are for example the part warpage, the crystallization behavior or powder
    ageing effects, which have to be considered for optimized process controls. Nevertheless,
    the inner temperature distribution and history during the cooling process is difficult
    to measure and less known yet. In this work, a Finite Element (FE) model is developed
    to understand and predict the temperature distribution and history within the
    part cake during the cooling process. Therefore, the thermal boundary conditions
    of a laser sintering system are analyzed and relevant parameters are identified.
    A basic FE model is set up in ABAQUS CAE software considering a part-free powder
    cake. Important thermal parameters of the bulk powder and the environment are
    adjusted and verified in relation to experimental in-process measured data. With
    this model it is possible to predict position-dependent cooling rates as a function
    of significant job parameters, for example the job height or the environmental
    conditions during the cooling phase. In combination with extended in-process temperature
    measurements and a consideration of built parts, this model will be an important
    tool for the development of optimized process controls.

  text: One barrier of laser sintering (LS) to become the main process for Direct
    Manufacturing (DM) is the surface quality of LS parts. Hence, the property which
    has to be improved is the rough surfaces of LS parts due to the layered structure.
    Another additional effect is the incomplete melting of powder particles on the
    surface due to the high process temperature. In this paper we demonstrate our
    approach of a theoretical model for the topography of LS part surfaces. We investigated
    the surface roughness as a function of surface orientation. Considering that the
    model involves further variables as layer thickness, particle density and particle
    size distribution to describe the topography precisely. Experimental results were
    used to optimize and check the results of the model.

  text: 'The reproducibility and reliability of quality aspects are an important challenge
    of the polymer laser sintering process. However, existing quality concepts and
    standardization activities considering influencing factors along the whole process
    chain have not been validated experimentally yet. In this work, these factors
    are analyzed and kept constant to obtain a reliable material data set for different
    layer thicknesses and testing temperatures. In addition, material qualities regarding
    powder ageing effects are analyzed using different build heights and layer thicknesses:
    while an increase of the layer thickness reduces mechanical part strength and
    density, it also results in a less intense thermal ageing of unmolten powder due
    to shorter build times.'

  text: Because of the large surface area of colloids interface effects are dominant
    in contrast to volume effects. The study presents experimental results of the
    direct transfer of magnetite nanoparticles from an aqueous to a non-miscible organic
    phase. The starting point is a water-based colloid that is synthesized through
    a precipitation reaction. The transfer is based on the adsorption of surfactants
    onto the particle surface at the liquid–liquid interface. While penetrating the
    liquid–liquid interface, the particles are covered with surfactants and a partial
    de-agglomeration is initiated. The intention is to produce a stable organic colloid,
    which has important applications in industry. The optimized process parameters
    for the successful phase transfer process, the adsorption reactions at the liquid–liquid
    interface and the stabilization of primary particles in the organic phase are
    demonstrated.

  text: 'In this work, the quality of laser sintered parts is investigated along a
    defined process chain for a nylon 12 material (PA 2200) on an EOSINT P395 laser
    sintering system. Important influencing factors are figured out. Rheological powder
    characterization methods are investigated as well as mechanical, physical and
    other chosen part properties. The concept allows reproducible part quality characteristics
    and is used to obtain (testing) temperature dependent material data. It can also
    be extended on further materials based on nylon 12: PA 2241 FR, which is convenient
    for the aircraft industry due to its flame-retardant properties, and PA 2221,
    which has economic advantages due to a lower material consumption.'

  text: Laser Sintering is a powder based additive manufacturing technology. The amount
    of used powder, which is not sintered, can be refreshed and used for further building
    jobs. Due to cost reduction, better mechanical properties and a simpler processing
    it is reasonable to combine virgin and used powder for part manufacturing. During
    the building time the powder is thermally loaded and its structure is changed.
    State of the art in laser sintering is a defined powder ratio. Since the powder
    ageing depends on the individual history of sintering, this procedure cannot ensure
    a defined powder quality. However, for a serial production it is necessary to
    characterize the raw material, as well as all other steps along the process chain,
    in order to ensure a high reproducibility and reliability. Rheological, physical
    and particle properties are considered to correlate powder and chosen material
    properties. Different powder qualities adjusted by the Melt Volume Rate (MVR)
    are tested using promising rheological properties like viscosity or molecular
    weight. Investigations about powder bed density, bulk properties as well as thermal
    characterization complement the experimental setup. These parameters are correlated
    with mechanical, electrical, thermal and physical material properties of laser
    sintered parts. The most important influencing factors along the process chain
    are kept constant. At the end a procedure is shown to obtain a defined powder
    quality. This procedure will be transferred to other materials and will be tested
    using other laser sintering machines of the same type as well as other types.

  text: The sintering of vitreous nanoparticle doublets is investigated numerically
    by a volume of fluid method coupled to Hamaker summation and experimentally by
    a high-temperature sintering flow reactor as well as by doublet shape analysis
    in the transmission electron microscope. In particular, the characteristic differences
    between nanoparticulate and bulk sintering are studied. The sintering mechanism
    of vitreous nanoparticles is determined to be viscous flow with interparticle
    van der Waals interactions acting as additional driving force. The early stages
    of the nanoparticle sintering kinetics are inversely proportional to the square
    of the particle size, instead of an indirect proportionality to the first order
    of the particle size for the entire bulk process. The transition between nanoparticulate
    and bulk sintering is localised to primary particle diameters of approx. 200–300
    nm.

  text: The quality of laser sintered parts, in this work, manufactured by polymer
    laser sintering by using an EOSINT P395 Laser Sintering system, depends on several
    steps along the process chain. The first step is the characterization of the powder
    quality, whereas the rheological and physical investigations of nylon 12 powder
    are shown. By changing some important influencing factors, for example the powder
    ratio, the powder ageing and the moisture content, the influence on mechanical
    and physical properties, density and porosity, are investigated. The composition
    of the used powder is known. The previous process (storage conditions, etc.) as
    well as the laser sintering process (regarding energy density, temperature, etc.)
    is kept constant for the duration of this work. Regarding the post process in
    this work the cooling down phase is investigated as well. With an automatically
    blasting system it is possible to keep the post process parameters blasting distance
    and blasting time, constant. All of the tests will be performed using dry and
    conditioned test specimens. This work is showing the dependence on mechanical,
    rheological and physical parameters by varying important influencing factors along
    the laser sintering process quality chain.

  text: The aim of this paper is the description and evaluation of physical properties
    like porosity and density and their influence on mechanical properties of laser
    sintered polyamide parts. For example, by reducing the porosity an increase of
    mechanical properties is possible. The correlation of laser parameters to these
    properties is investigated in detail. The energy density is an important parameter
    for the laser sintering process. By changing laser power, scan velocity and hatch
    distance an influence on manufactured components is given. A systematic variation
    of all three laser parameters is performed. A comparison of results obtained at
    constant energy densities obtained by varying these relevant parameters accordingly
    is shown as well.

  text: This work investigates the mechanisms which lead to the formation of silicon
    nanoparticles with narrow size distributions by means of population balance modeling.
    The model accounts for the full aerosol process, including chemical reaction,
    nucleation from supersaturated vapor, growth and agglomeration. The results are
    in good agreement with experimental data. The effects of the process parameters
    temperature, silane concentration and reactor total pressure are systematically
    investigated. The simulation allows an in-depth insight into the particle formation
    mechanism and reveals the key requirements which are necessary for the generation
    of narrow particle size distributions. In this mechanism, only a short nucleation
    burst occurs, while surface growth plays the dominant role in silane precursor
    consumption. A key role is attributed to condensation, because the numerical calculations
    can only reflect the experimental observations, if the condensation mechanism
    is included in the model.

  text: A study on the feasibility of aerosol processing of nearly monodisperse silicon
    nanoparticles via pyrolysis of monosilane in a hot wall reactor is presented.
    For optimal conditions silicon nanoparticles with a geometric standard deviation
    of 1.06 were synthesized at a production rate of 0.7 g/h. The size of the particles
    could be precisely controlled in the range of 20–40 nm, whilst maintaining a geometric
    standard deviation in the range of 1.06–1.08, by proper choice of the governing
    parameters temperature, residence time and precursor concentration. The results
    show that narrow particle size distributions can only be obtained in the temperature
    range between 900 and 1100 °C, as long as both the initial silane concentration
    (1 mbar silane partial pressure) and the reactor total pressure are low (25 mbar).
    This regime for the production of narrow particle size distributions has not been
    identified in prior work on the thermal decomposition of silane. Narrowly distributed
    particles can be obtained under conditions where nucleation and particle growth
    are separated and the agglomeration rates are negligible.

  text: To improve the understanding of the poor dispersability of fumed silica nanoparticle
    agglomerates, the stability of highly defined agglomerated model particles was
    investigated. The high temperature synthesis conditions for fumed silica were
    simulated by tempering. Along with electron-microscopical analysis of the sintering
    necks, the interparticle forces were investigated by energy resolved fragmentation
    analysis based on low pressure impaction. At temperatures above 1,000 °C the fragmentability
    of the agglomerates rapidly decreased while the energy necessary for fragmentation
    increased. The development of sintering necks was observed for temperatures exceeding
    1,300 °C. Comparison of the experimental data with the fragmentation behaviour
    of a commercially produced fumed silica indicated solid state contacts (sintering
    necks) as being most numerous in the agglomerates resulting in limited fragmentability.

  text: In this paper, we consider a model for precipitation experiments based on
    the population balance equation. The study revealed a high sensitivity of the
    system with respect to the modeling of intrinsic parameters, motivating a comprehensive
    validation of the estimates. In the forward simulation the impact of the influencing
    parameters including surface energy, nucleus size and distribution is investigated.
    Subsequently we construct a simplified model of the precipitation process in such
    a way that it is orbitally flat in terms of control theory, which enables the
    inverse calculation of the parameters. The numerical results of the inverse simulation
    for the interfacial energy have been compared to a physical model. The possibility
    of solving the inverse problem provides a promising way of estimating hardly measurable
    quantities for more complex molecules.
