Especially in the field of dentistry, jewelry and related branches that require individualized or even one-of-a-kind products, the direct digital manufacturing process opens up new ways of design and manufacturing. In these fields, mostly small and medium sized businesses (SME) are operating which do not have sufficient human and economic resources to invest in this technology. But to stay competitive, the application of AM can be regarded as a necessity. In this situation a new desktop machine (Realizer SLM 50) was introduced that cost about 1/3 of a shop floor SLM machine and promises small quality parts. To find out whether the machine really is an alternative for SMEs the University of Applied Science, Aachen, Germany, designed, build and optimized typical parts from the dentistry and the jewelry branches using CoCr and silver material, the latter being new with this application. The paper describes the SLM procedure and how to find and optimize the most important parameters. The test is accompanied by digital simulation in order to verify the build parameters and to plan future builds. The procedure is shown as well as the resulting parts made from CoCr and silver material.}, language = {en} } @article{Knueppel2012, author = {Kn{\"u}ppel, Mark}, title = {Außerbilanzielle Korrekturen}, series = {Handbuch der Bilanzierung online}, journal = {Handbuch der Bilanzierung online}, editor = {Federmann, Rudolf and Kußmaul, Heinz and M{\"u}ller, Stefan}, publisher = {Haufe}, address = {Freiburg}, issn = {0172-0392}, pages = {Artikel HI 1380074}, year = {2012}, language = {de} } @article{SabitovaEbertLenzetal.2013, author = {Sabitova, A. and Ebert, Ph. and Lenz, A. and Schaafhausen, S. and Ivanova, L. and D{\"a}hne, M. and Hoffmann, A. and Dunin-Borkowski, R.

However, the chlorinated chain ends cause a low thermal stability requiring mild Cl/H substitution. The product exhibits high thermal stability and excellent melt-compounding properties. Blends of oligomeric and commercial PVAc show single glass transition temperatures which decrease with higher oligomer content and exhibit small negative deviations from Fox' linear additivity rule. This indicates plasticization and miscibility being mainly due to entropic effects. Injection-moulded thick specimens show ductile behaviour at oligomer contents >10 wt \%, while sheets with a thickness of 0.2-0.5 mm appear flexible already at 7.5 wt \%. The oxygen permeability coefficients are an order of magnitude lower than those of low-density polyethylene.
