FormFutura1.75mm StoneFil - Pottery Clay - 3D Printer Filament

Este filamento se comporta correctamente en torre de temperatura, con descuelgues correctos de 195 a 235 grados de extrusor.Se pega correctamente a cama de cristal desnudo a 60 grados.Tiene un comportamiento bastante líquido, con lo cual conviene usar una velocidad de desplazamiento (travel speed) alta para no verter el filamento al viajar de una zona de impresión a otra.Conviene usar retracción de 2-4mm (extrusor directo), según modelo de impresora.Es fácil crear efectos interesantes cambiando de filamento (pj. formfutura metalfil copper) durante un rango de capas, creando una banda metálica (ver fotos).

I'd first like to say that this is not about the brand of filament. It's normally very good filament and works great and I can wholeheartedly recommend it.However because of the nature of the filament it goes bad over time and should be used up within a year of production. It seems that Amazon sent me very old filament.As you can see in the comparison pictures the Amazon one looks very rough almost hair like it also feels softer and brittler than "fresh" one. The color of the filament is also darker.I've yet to complete a print with it even though I've tried every possible change in print settings and printer maintenance, it always stops extruding which is in contrast to the fresh filament which printed perfectly every time.The print in which I switched to the Amazon one failed quickly after changing and the print quality and infill look horrible.So the brand of filament is very good, but you might get old stock from Amazon which is unusable.
