{"product_id":"hotend-heatsink-xl-mk4","title":"Hotend HeatSink XL\/MK4","description":"\u003cp style=\"text-align: justify;\"\u003eThe Hotend heatsink is an original Prusa spare part for the Nextruder hotend assembly, equipping Prusa MK4, MK4S, MK3.9, MK3.9S, XL printers, as well as CORE One series printers. The part ensures thermal dissipation from the upper part of the melt chamber and limits heat transfer to the cold zone of the filament tube, which prevents heat creep and clogging during printing.\u003c\/p\u003e\n\u003ch2\u003eContents and replacement\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eThe delivered assembly includes the hotend heatsink and the original Prusa load cell, a force sensor used by the Nextruder for automatic first-layer calibration and nozzle\/bed contact detection. Replacement is typically performed in case of repeated calibration failures, filament jamming due to abnormal heatsink heating, or as preventive maintenance after intensive production use. The part is not compatible with MK3, MK3S, MK3.5\/MK3.5S, MINI generations, nor with HT90 and Prusa enclosures: check the printer model before ordering.\u003cbr\u003e\u003cbr\u003eInstallation should follow the corresponding Prusa repair manual for the model, available at help.prusa3d.com.\u003c\/p\u003e\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eType\u003c\/th\u003e\n\n\u003ctd\u003eSpare part\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eFunction\u003c\/th\u003e\n\n\u003ctd\u003eHotend heatsink + force sensor\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eSystem\u003c\/th\u003e\n\n\u003ctd\u003eNextruder\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003ePackage contents\u003c\/th\u003e\n\n\u003ctd\u003e1 × hotend heatsink + 1 × load cell\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eOrigin\u003c\/th\u003e\n\n\u003ctd\u003eOriginal Prusa Research part\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 MK4 and MK4S\u003c\/li\u003e\n\n  \u003cli\u003ePrusa MK3.9 and MK3.9S\u003c\/li\u003e\n\n  \u003cli\u003ePrusa XL\u003c\/li\u003e\n\n  \u003cli\u003ePrusa CORE One and CORE One+\u003c\/li\u003e\n\n  \u003cli\u003ePrusa CORE One L\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"Prusa","offers":[{"title":"Default Title","offer_id":56893899768152,"sku":"IDF_15348_IDS_1574","price":44.08,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0938\/8979\/0296\/files\/PRUSAHOTENDHEATSINK.png?v=1779206001","url":"https:\/\/3dprint.shop\/en\/products\/hotend-heatsink-xl-mk4","provider":"3dPrint.Shop","version":"1.0","type":"link"}
