Selective laser sintering (SLS) of thermoplastic materials is an additive manufacturing process that overcomes the boundary between prototype construction and functional components. This technique also meets requirements traditional established production processes. Crystallization behavior one most critical properties during cooling needs to be fully understood. Due huge influence crystallization on mechanical thermal properties, it important investigate this more closely. A commercial SLS...
In this second part of our survey on experimental research in Synthetic Molecular Communication (SMC), we review works long-range SMC systems, i.e., systems with communication ranges more than a few millimeters. Despite the importance for evolution towards mature paradigm that will eventually support revolutionary applications beyond reach today's prevalent paradigms, existing body literature is still comparatively sparse. Long-range have been proposed information transmission two types...
In this research, the curing degree of an acrylate-based monomer using direct UV-assisted writing technology was characterized by differential photo calorimetry (Photo-DSC) to investigate behavior. Triggered UV light, duo function group 1,6-Hexamethylene diacrylate (HDDA), photoinitiator 1173 and photoinhibitor exhibit a fast process.

Additive manufacturing technologies, such as selective laser melting of polymers enable complex parts without tools and forms. Due to high temperature during processing, a degradation the used plastic powder occurs. The unmolded material in building chamber, so-called partcake, can be removed from finished component after reused for another process. To realize reproducible part properties refreshing partcake is necessary. This paper presents results on investigations behavior polyamide 12...
