Manufacturing by combining Selective Laser Melting and Selective Laser Erosion / laser re-melting
CIRP Annals - Manufacturing Technology, 2011Co-Authors: Evren Yasa, Jean‐pierre Kruth, Jan Patrick DeckersAbstract:This study presents an experimental investigation to improve Selective Laser Melting (SLM) regarding aspects such as surface roughness, density, precision and micro machining capability by employing secondary Processes such as Selective Laser Erosion (SLE) and laser re-melting. SLM is a layered additive manufacturing technique for the direct fabrication of functional parts by fusing together metal powder particles. Laser re-melting, applied after each layer or only on the top surfaces, is used to improve the roughness and density while SLE, a Subtractive Process, is combined with SLM to improve the precision and micro machining capability.

direct inkjet printing of dental prostheses made of zirconia
Journal of Dental Research, 2009Co-Authors: Jorg Ebert, K Uibel, U Koops, O. Weiss, Alexander Zeichner, Emre Özkol, R Telle, Horst FischerAbstract:CAD/CAM milling systems provide a rapid and individual method for the manufacturing of zirconia dental restorations. However, the disadvantages of these systems include limited accuracy, possible introduction of microscopic cracks, and a waste of material due to the principle of the ‘Subtractive Process’. The hypothesis of this study was that these issues can be overcome by a novel generative manufacturing technique, direct inkjet printing. A tailored zirconia-based ceramic suspension with 27 vol% solid content was synthesized. The suspension was printed on a conventional, but modified, drop-on-demand inkjet printer. A cleaning unit and a drying device allowed for the build-up of dense components of the size of a posterior crown. A characteristic strength of 763 MPa and a mean fracture toughness of 6.7 MPam0.5 were determined on 3D-printed and subsequently sintered specimens. The novel technique has great potential to produce, cost-efficiently, all-ceramic dental restorations at high accuracy and with a m...

The novel technique has great potential to produce, cost-efficiently, all-ceramic dental restorations at high accuracy and with a minimum of materials consumption.

Interfacial characteristic and mechanical performance of maraging steel-copper functional bimetal produced by selective laser melting based hybrid manufacture
Materials and Design, 2018Co-Authors: Chaolin Tan, Kesong Zhou, Wenyou Ma, Liu MinAbstract:A combination of selective laser melting (SLM) additive manufacture and Subtractive Process was explored to produce maraging steel‑copper bimetal. Relationships among laser parameter, interfacial characteristic and mechanical performance are elucidated. A metallurgical bonded interface with a 30–40 μm inter-diffusion region is formed. Gradient submicro grains with strong 〈111〉 orientation exhibit at the interface, which owe to high cooling rate and temperature gradient caused by high thermal conductive copper. A selected region of the interface was extracted by focused ion beam (FIB) for interfacial bonding analysis. The bonding mechanism is revealed and illustrated in detail. Interfacial intense Marangoni flows pull the copper toward the molten pool of maraging steel and the liquid maraging steel penetrates into the melting copper, which contributes to interfacial bonding. The bonding strength of hybrid Processed bimetals are evaluated. Fracture in tensile is not present at the interface but on the copper side. The highest flexural strength reaches 557 MPa, which is slightly higher than that of the copper. Effects of parameter on fracture behaviors are also elucidated. This hybrid manufacture increases the productivity and functionality of the direct SLM-produced part, and provides a new approach for producing high-performance functional dissimilar bimetals based on laser additive manufacture.
