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.\u003C\/p\u003E\n","url":"https:\/\/www.inptdat.de\/dataset\/high-speed-thermal-microscopy-plasma-microprinting-atmospheric-pressure","state":"Active","private":true,"revision_timestamp":"Tue, 02\/25\/2020 - 15:53","metadata_created":"Tue, 07\/09\/2019 - 12:07","metadata_modified":"Tue, 02\/25\/2020 - 15:53","creator_user_id":"0e27023c-5517-4b3f-b96e-c939dc6a74ff","type":"Dataset","resources":[{"id":"73f9ee9b-9b98-4b88-8d9a-9d095a09cd90","revision_id":"","url":"https:\/\/www.inptdat.de\/system\/files\/node101_movie.mp4","description":"\u003Cp\u003EThe high-speed video 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.\u003C\/p\u003E\n","format":"mp4","state":"Active","revision_timestamp":"Fri, 02\/14\/2020 - 19:44","name":"High-speed thermal microscopy of plasma microprinting (high-speed video)","mimetype":"video\/mp4","size":"78.99 MB","created":"Tue, 07\/09\/2019 - 12:25","resource_group_id":"8213480c-adb6-4936-8811-f1dd8f8b3a2f","last_modified":"Date changed  Fri, 02\/14\/2020 - 19:44"}],"tags":[{"id":"508469c8-02c8-4bf0-8e68-311f373d87f7","vocabulary_id":"2","name":"plasma microprinting"},{"id":"d3026044-fb75-45c1-805c-ea06c4332bfe","vocabulary_id":"2","name":"thermal diagnostic"},{"id":"1831194b-f1dc-43b0-9bb1-fe449c6d5320","vocabulary_id":"2","name":"self-controlling mechanism"}],"groups":[{"description":"\u003Cp\u003E\u003Cstrong\u003ELeibniz Institute for Plasma Science and Technology\u003C\/strong\u003E\u003Cbr \/\u003E\nFelix-Hausdorff-Str. 2\u003Cbr \/\u003E\n17489 Greifswald\u003Cbr \/\u003E\nGERMANY\u003C\/p\u003E\n\u003Cp\u003E\u003Ca href=\u0022https:\/\/www.inp-greifswald.de\/en\/\u0022\u003Ehttps:\/\/www.inp-greifswald.de\/en\/\u003C\/a\u003E\u003Cbr \/\u003E\n\u003Cspan class=\u0022spamspan\u0022\u003E\u003Cspan class=\u0022u\u0022\u003Ewelcome\u003C\/span\u003E\u003Cimg class=\u0022spam-span-image\u0022 alt=\u0022at\u0022 width=\u002210\u0022 src=\u0022\/sites\/all\/modules\/spamspan\/image.gif\u0022 \/\u003E\u003Cspan class=\u0022d\u0022\u003Einp-greifswald\u003Cspan class=\u0022t\u0022\u003E [punkt] \u003C\/span\u003Ede\u003C\/span\u003E\u003C\/span\u003E\u003C\/p\u003E\n\u003Cp align=\u0022justify\u0022\u003EThe Leibniz Institute for Plasma Science and Technology (INP) is the largest non-university institute in the field of low temperature plasmas, their basics and technical applications in Europe.
