ABS is made out of oil-based resources and it has a much higher melting point than PLA plastic. It’s also stronger and harder. It is an economical plastic notable for its low degree of shrinkage and warping.

Diameter Tolerances
Cheap filament usually extruded at lighter tolerances and with materials of questionable origin. For 1.75mm and 3mm filament, the outer diameter should not exceed +/- 0.1mm, for example,+/-0.05mm is OK. Anything over these tolerances could jam the extruder of the nozzle’s inner chamber, which is machined to exacting tolerances. Additionally, the use of out of tolerance filament will cause over or under extrusion, which is the major cause of blobbing and voids in the finished print. This is because the slicing software used to prepare the style for printing calculates exactly how fast to extrude based on a constant filament size. Our filament quality is very good with tolerances: +/-0.02mm.

Air Bubbles
Moisture laden ABS will tend to bubble and spurt from the tip of the nozzle when printing; reducing the visual quality of the part, part accuracy, strength and introducing the risk of a stripping or clogging in the nozzle. Our ABS filaments DO NOT have air bubbles.

Package includes:
1. 1x 3D printer filament
2. 1x leather box

1: PLA/ABS dual color filaments net weight: 1KG/2.2lbs, gross weight: 3.08lbs.
2: Flexible and PVA filaments are only used for short-range feeding 3D printer.
3: PVA filament should be kept in sealed, and PVA filament is only used as a support material. So, PVA must be used in double nozzles.
4: Print speed should be controlled in the range of 20-40mm/s while using wood、flexible or PVA filaments in ceae of print failure.

Compatible with all FDM 3D printer such as Makerbot, Mendel, Prusa, Huxley, BFB series, RepRap, Rapman, Solidoodle etc
