{"product_id":"prusa-nozzle-brass-cht","title":"Prusa Nozzle brass CHT","description":"\u003cp style=\"text-align: justify;\"\u003eThe Prusa Nozzle brass CHT 0.4 mm is a high-flow brass nozzle designed for the Nextruder extrusion system developed by Prusa Research. It integrates CHT (Core Heating Technology), which splits the melt channel into multiple sub-channels to increase the heat exchange surface with the filament and improve heating uniformity.\u003cbr\u003e\u003cbr\u003eThis results in a higher volumetric flow rate than a conventional brass nozzle of the same diameter, useful for high-speed printing or large parts without compromising extrusion quality.\u003c\/p\u003e\n\u003ch2\u003eDesign and Implementation\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eThe nozzle features an all-metal design: it combines the nozzle and the heat break into a single piece, eliminating any PTFE tube in the filament path within the Nextruder. This architecture improves extrusion reliability over time and allows for quick nozzle changes without complete disassembly of the hotend. Brass material is suitable for non-abrasive filaments (PLA, PETG, ABS, ASA, PC, etc.); for fiber-filled or abrasive materials, a hardened steel version should be used. Several diameters are available in the range.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003ePart Type\u003c\/th\u003e\n\n\u003ctd\u003eAll-metal high-flow nozzle (integrated nozzle + heat break)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eExtrusion Platform\u003c\/th\u003e\n\n\u003ctd\u003eNextruder\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eNozzle Diameter\u003c\/th\u003e\n\n\u003ctd\u003e0.4 mm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eMaterial\u003c\/th\u003e\n\n\u003ctd\u003eBrass\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eTechnology\u003c\/th\u003e\n\n\u003ctd\u003eCHT (Core Heating Technology) – multi-channel heating\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eFilament Guide\u003c\/th\u003e\n\n\u003ctd\u003eAll-metal, no PTFE\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eRecommended Filaments\u003c\/th\u003e\n\n\u003ctd\u003eNon-abrasive (PLA, PETG, ABS, ASA, PC, etc.)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eQuantity per Kit\u003c\/th\u003e\n\n\u003ctd\u003e1 nozzle\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eUsage\u003c\/th\u003e\n\n\u003ctd\u003eSpare part \/ high-flow printing accessory\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\n\u003c\/table\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cul\u003e\n\n  \u003cli\u003ePrusa printers equipped with the Nextruder extrusion system\u003c\/li\u003e\n\n  \u003cli\u003eOriginal Prusa MK4 and MK4S\u003c\/li\u003e\n\n  \u003cli\u003eOriginal Prusa MK3.9 and MK3.9S\u003c\/li\u003e\n\n  \u003cli\u003eOriginal Prusa XL\u003c\/li\u003e\n\n  \u003cli\u003eOriginal Prusa CORE One and CORE One+\u003c\/li\u003e\n\n  \u003cli\u003eOriginal Prusa CORE One L\u003c\/li\u003e\n\n  \u003cli\u003eCompatible with V6-format nozzles via the Nextruder V6 adapter (sold separately)\u003c\/li\u003e\n\n  \u003cli\u003eNot compatible with MK3S+, MK3S, MK3, MK2.5S, MK2.5, MK2S, MK2, MK3.5, MK3.5S, MINI, MINI+, HT90, MMUs (1, 2, 2S, 3), SL1 \/ SL1S, CW1 \/ CW1S, and MKx, XL, and MINI enclosures\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"Prusa","offers":[{"title":"0.4 mm","offer_id":57335236002136,"sku":"IDF__14517_IDS__2329","price":23.25,"currency_code":"EUR","in_stock":true},{"title":"0.6 mm","offer_id":57335251403096,"sku":"IDF__14518_IDS__2330","price":23.25,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0938\/8979\/0296\/files\/Prusa_Nozzle_brass_CHT_04.jpg?v=1779280397","url":"https:\/\/3dprint.shop\/en\/products\/prusa-nozzle-brass-cht","provider":"3dPrint.Shop","version":"1.0","type":"link"}
