RESISTIVELY HEATED PRINTHEAD FOR A 3D PRINTER

A printhead (100) for a 3D printer which comprises two large walls (108) and two small walls (110) which between them define a right-angled parallelepipedal cavity (102), wherein each small wall (110) is made from an electrically non-conducting material, wherein each large wall (108) comprises a cen...

Zusammenfassung:	A printhead (100) for a 3D printer which comprises two large walls (108) and two small walls (110) which between them define a right-angled parallelepipedal cavity (102), wherein each small wall (110) is made from an electrically non-conducting material, wherein each large wall (108) comprises a central wall (112) and two lateral walls (114), one on each side of the central wall (112), wherein each lateral wall (114) is made from an electrically non-conducting material, and wherein the two central walls (112) face one another, are made from an electrically conducting material, and are electrically connected to an electric generator which generates an alternating current and a difference in electric potential across them. Une tête d'impression (100) pour une imprimante 3D qui comporte deux grandes parois (108) et deux petites parois (110) qui définissent entre elles, une cavité (102) parallélépipédique rectangle, où chaque petite paroi (110) est réalisée dans un matériau électriquement non conducteur, où chaque grande paroi (108) comporte une paroi centrale (112) et deux parois latérales (114) de part et d'autre de la paroi centrale (112), où chaque paroi latérale (114) est réalisée dans un matériau électriquement non conducteur, et où les deux parois centrales (112) se font face, sont réalisées dans un matériau électriquement conducteur, et sont électriquement reliées à un générateur électrique qui génère un courant alternatif et une différence de potentiel électrique entre elles.
