Review: Tolles Gerät, das mir das Drucken viel leichter macht - Ich benutze die SUNLU Filament Trockner Box S4 jetzt einige Zeit und bin richtig begeistert. Besonders praktisch finde ich, dass ich gleich bis zu vier Spulen gleichzeitig trocknen oder lagern kann – das spart mir viel Zeit und Stress. Das Gerät heizt super schnell auf und hält die Temperatur konstant, sodass mein Filament immer perfekt trocken bleibt. Die Feuchtigkeitskontrolle im Display gibt mir zudem viel Sicherheit, dass nichts schimmelt oder verdirbt. Klar, die Lüfter sind hörbar, aber für mich kein großes Problem. Wer viel 3D druckt, sollte sich diese Box definitiv anschauen – sie hat mir meine Druckqualität deutlich verbessert!
Review: Bra - Perfekt för mig
