Get outstanding 3D printing results when you use 1.75mm ABS 3D Printer Filament from Monoprice!ABS is one of the most commonly used filament types in 3D printing. It has a high tensile strength and good overall toughness. It has a low density and is softer than PLA, which means lower weight and lower cost when printing large models. Hardness is such that no white dot appears when bending.This 1 Kg spool features a thickness of 1.75mm �0.10mm, with a roundness variation of only 0.05mm. It has a nominal processing temperature of 230� C (446�F). Thickness and roundness factors are laser measured at the factory to ensure accuracy over the entire length of the filament.The negatives of using ABS is that it can give off a white smoke with a concentrated odor. It is best to ensure that the printing room is well ventilated when using ABS.Additionally, it has a high moisture absorption rate. Depending on the overall humidity level of the printing environment, an opened spool can absorb enough moisture after a couple of days that high temperature printing could cause bubbles or pocks in the extrusion. It is therefore recommended to not open a spool until you are ready to print and to store any unused portion with with silca gel and/or an active dehumidifier to reduce the amount of moisture it can absorb.Reel Dimensions * Reel Diameter 195mm (7.68)* Hub Diameter 95mm (3.74)* Spindle Diameter 38mm (1.50)* Reel Width 80mm (3.15)*** 30-day easy returns.
