[article]  inKUNSTSTOFFE INTERNATIONAL > Vol. 107, N° 10 (10/2017) . - p. 67-70 Titre : 3D-print with affordable pellets : A novel type of print head gives fresh impetus to the FDM branch Type de document : texte imprimé Auteurs : Moritz Stubenruss, Auteur Année de publication : 2017 Article en page(s) : p. 67-70 Langues : Anglais (eng) Catégories : Impression tridimensionnelle Impression tridimensionnelle -- Appareils et matériels Modélisation par dépôt en fusion Index. décimale : 668.4 Plastiques, vinyles Résumé : Is there a quantum leap on the horizon for 3D printing? The prototype of a newly developed 3D printer is able to process commercial pellets – also those of high-performance plastics such as PEEK, PPS, PSU, PA and PC, with or without fibers. The machine applies the usual strand-deposition process, though with a simply designed print head that includes a radial screw. Note de contenu : - Downsides of filament printers - Print head for an ingenious twist - Axial approach bound to fail - What makes welded joints so strong - Unbeatable price - FIGURES : 1. The prototype of the 3D printer, which is able to process commercial pellets. Inert gas prevents oxidation of the plastic melt - 2. Attached to a disk, the spiral drives the plastic from the outside to the inside, towards the nozzle outlet. A force acting upon the disk from above controls the pressure between disk and the opposite area where the outlet is, and therefore the plastic extrusion process itself En ligne : https://drive.google.com/file/d/1DpJZLjTMehJCKGfEFpSfURhfWLb-TWf9/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=29284 [article]
