Modeling of selective laser sintering/selective laser melting
Selective laser sintering and selective laser melting are powder based additive manufacturing (AM) process that can rapidly manufacture parts with comparable mechanical properties to conventional manufacturing methods directly from digital files. However, the processing recipe development and design optimization of AM parts are often based on trial and error which erodes the benefit of AM. Mode...
متن کاملOn model of microstructure formation during selective laser melting of metal powder bed
A model of phase field has been developed to investigate the microstructure evolution during selective laser melting (SLM) of metal powder bed. A two-component (degree of order, orientation field) ordering parameter has been used, for which the permissive relationships have been derived reasoning from the principle of entropy production positivity. The application of this principle has made pos...
متن کاملThree-dimensional finite element thermal analysis in selective laser melting of Al-Al2O3 powder
The selective laser melting (SLM) of aluminium-based composites continues to be a challenge due to the high reflectivity, high thermal conductivity and oxidation of aluminium, all of which directly influence the thermal performance of each layer during SLM. Due to the extremely rapid melting and cooling rate of aluminium, however, it is difficult to measure thermal performance within practical ...
متن کاملGenerative ManufacturinG Methods: selective laser MeltinG
Since the late eighties generative manufacturing methods have been established as manufacturing systems for the product development in various sectors of industries. After only used for the production of demonstration models (Rapid Prototyping) is the rapid tooling and manufacturing now able to service a steady increasing range of applications. In order to achieve this status the range of usabl...
متن کاملBioresorbable Implants using Selective Laser Melting
Using bioresorbable materials implants can be manufactured which dissolve in the human body and are replaced by natural bone structure. For large implants an interconnecting porous structure needs to be integrated in the implant for a good vascularisation. Using additive manufacturing technology these internal structures can be directly manufactured. The structure can be designed by consequent ...
