T1  - Grundlagen des Rapid Prototyping: Eine Kurzdarstellung der Rapid Prototyping Verfahren
N2  - Generative Verfahren sind seit etwa 1987 in den USA und seit etwa 1990 in Europa und Deutschland in Form von Rapid Prototyping Verfahren bekannt und haben sich in dieser Zeit von eher als exotisch anzusehenden Modellbauverfahren zu effizienten Werkzeugen für die Beschleunigung der Produktentstehung gewandelt. Mit der Weiterentwicklung der Verfahren und insbesondere der Materialien wird mehr und mehr das Feld der direkten Anwendung der Rapid Technologie zur Fertigung erschlossen. Rapid Technologien werden daher zum Schlüssel für neue Konstruktionssystematiken und Fertigungsstrategien.
N2  - Generative procedures have been known under the term of 'rapid prototyping method' for about 18 years in the USA and about 15 years in Europe and Germany. In this time they changed from what was regarded as being a rather exotic way of model construction procedures to a very efficient and useful instrument for faster product manufacturing. In the course of the further development of the methods, and in particular the materials, the field for direct application of rapid technology opens up for manufacturing. Therefore rapid technologies become the key for new construction systematics and manufacturing strategies.

T1  - Improving the Mechanical Strength of Dental Applications and Lattice Structures SLM Processed
JF  - Materials
N2  - To manufacture custom medical parts or scaffolds with reduced defects and high mechanical characteristics, new research on optimizing the selective laser melting (SLM) parameters are needed. In this work, a biocompatible powder, 316L stainless steel, is characterized to understand the particle size, distribution, shape and flowability. Examination revealed that the 316L particles are smooth, nearly spherical, their mean diameter is 39.09 μm and just 10% of them hold a diameter less than 21.18 μm. SLM parameters under consideration include laser power up to 200 W, 250–1500 mm/s scanning speed, 80 μm hatch spacing, 35 μm layer thickness and a preheated platform. The effect of these on processability is evaluated. More than 100 samples are SLM-manufactured with different process parameters. The tensile results show that is possible to raise the ultimate tensile strength up to 840 MPa, adapting the SLM parameters for a stable processability, avoiding the technological defects caused by residual stress. Correlating with other recent studies on SLM technology, the tensile strength is 20% improved. To validate the SLM parameters and conditions established, complex bioengineering applications such as dental bridges and macro-porous grafts are SLM-processed, demonstrating the potential to manufacture medical products with increased mechanical resistance made of 316L.
