            "description": "The HelixJet (https://www.inptdat.de/helixjet) was applied to simultaneous melting and plasma treatment of polyamide (PA 12) microparticles (diameter 60 \u00b5m) used conventionally for 3D printing by laser sintering. This proof-of-principle experiment demonstrated that gaussian thickness profiles of PA 12 can be printed using the HelixJet with a rapid rate of 200 mg/s (peak growth 2 mm/s) and with advantageous material properties. The key element of this novel process is the self-regulated balance between material melting and plasma quenching. As a result, particles leaving the HelixJet with the gas flow velocity have a temperature slightly below the melting temperature preventing material degradation that would occur at higher temperatures. The above process has been captured with a high-speed infrared camera. The resulting movie combines the best temporal and spatial resolution for the studied process and reveals the particle temperature of 180\u00b0C to 190\u00b0C and their velocity of 0.5 m/s to 3 m/s depending on the radial position.",
