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.
