Its small diameter enables very fine details and smooth surfaces in print results, but requires precise leveling and tighter tolerances for material feed than larger nozzles.\u003c\/p\u003e \u003cp\u003eThe brass material transfers heat evenly to the filament and enables consistent extrusion, even at higher print speeds. The nozzle screws into standard extruder heads with an M6 or M7 thread and works with both Bowden systems and direct-drive systems, as long as the printer hot end operates between 200 and 300 degrees Celsius.\u003c\/p\u003e \u003cp\u003eThis fine nozzle is especially suitable for projects that require sharp edges, closely spaced structures, or precise mechanical parts. When printing with highly filled or fiber-reinforced materials, back pressure may increase and the nozzle may wear faster. Replacing the nozzle does not require recalibrating the printer firmware; simply screw in the new nozzle and configure the printer as usual.\u003c\/p\u003e \u003cp\u003eReplacement is necessary if the opening becomes restricted by wear or contamination, or if material leaks out. Check compatibility by verifying the thread (M6 or M7) and the hot end's installation height. The hot end should be cool before installation.\u003c\/p\u003e \u003ch3\u003eSafety Notice\u003c\/h3\u003e \u003cp\u003eThe nozzle heats up to 300 degrees Celsius during printing. Intended exclusively for building, maintaining, and testing 3D printers. Wait until it has cooled before installing or replacing it. If you are unsure about the correct installation position, consult a qualified electrician or the printer manufacturer.\u003c\/p\u003e \u003ch4\u003ePackage Contents\u003c\/h4\u003e \u003cul\u003e \u003cli\u003e1x 0.3 mm extruder nozzle for 1.75 mm filament\u003c\/li\u003e \u003c\/ul\u003e","brand":"Funduino","offers":[{"title":"Default Title","offer_id":66045608362333,"sku":"F23106591","price":3.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1074\/5649\/5965\/files\/03mm-extruder-duese-fuer-175mm-filament-funduino-4035335.png?v=1791489337","url":"https:\/\/funduino.com\/en\/products\/0-3mm-extruder-nozzle-for-1-75mm-filament","provider":"Funduino","version":"1.0","type":"link"}
