Thermal Stresses in Direct Metal Laser Sintering
In Direct Metal Laser Sintering objects are created by sequential sintering loose metal powder particles by means of laser technology. When the laser sintering process involves temperature gradients, thermal stresses develop. Corresponding residual stresses induce warping of the densified structure leading to unacceptable tolerance losses. This paper examines the role of laser beam scan pattern...
متن کاملPractical Issues in the Application of Direct Metal Laser Sintering
Direct Metal Laser Sintering (DMLS) was introduced to meet the objective of producing metal parts directly from CAD data. CRDM has accumulated six years of experience in applying this technique, mostly to prototyping parts for evaluation. For some applications, such as blow moulds, porosity generated in DMLS has proved to be beneficial, but for others a concession on tolerances or finish are ne...
متن کاملAccuracy evaluation of metal copings fabricated by computer-aided milling and direct metal laser sintering systems
PURPOSE To assess the marginal and internal gaps of the copings fabricated by computer-aided milling and direct metal laser sintering (DMLS) systems in comparison to casting method. MATERIALS AND METHODS Ten metal copings were fabricated by casting, computer-aided milling, and DMLS. Seven mesiodistal and labiolingual positions were then measured, and each of these were divided into the catego...
