Selective Laser Melting of Aluminum Based Materials

Selective Laser Melting is a technology that can be used with various materials including aluminum alloys. The most common and suitable for SLM are AlSi10Mg and AlSi12Mg. Scalmalloy is a innovative material that can be used as high-strength alternative for the mentioned materials. Aluminum alloys are also widely utilize in aircraft production. Selective Laser Melting technology with an appropriate material can be used as substitute of traditional casting or forging technology. Thanks to good mechanical properties and printability of Scalmalloy it can be easily used for this purpose. The proposed paper consists for part which covers fundamental knowledge about AM industry, technology basics and general description of SLM. Technology capabilities with particular emphasis on most part quality influential areas are shown. Second part covers results from mechanical testing. Results from static tests are presented as well as results from quality control reports. According to authors experience the best quality control procedures are shown. Within third section technology substitution for certain parts is presented taking into account part quality, strength, good printability and costs. For some parts non-destructive and destructive tests results were demonstrated.
