ABS, Acrylonitrile Butadiene Styrene, is a polymer that is molded and engineered to be a great material for 3D printing. It is a favorite filament among 3D printer users because it is light weight and durable. It can be injection molded which makes it perfect for 3D printing extruders. It has a high glass transition temperature to reduce deformation, but it is also low enough to be safely attainable with standard 3D printers. ABS is a hard strong plastic with some flexibility when compared to PLA. It is also soluble in Acetone, and it can be easily sanded and machined. It has good strength and machinability. In combination with the higher temperature resistance, it is often the preferred plastic among 3D printer users.
PLA - Some PLA filament colors are translucent and are hard to visualize through an eBay picture. Those colors are blue, brown, purple, red, orange, green, and yellow. - Polylactic Acid, is created from processing a number of plant products. PLA can be composted at commercial facilities unlike ABS which is derived from fossil fuels. PLA is a more earth friendly plastic. It is stronger and more rigid than ABS, and in general the printed objects will have a more glossy look and feel compared to ABS. Unlike ABS, PLA can be sanded and machined. PLA has a lower melting temperature compared to ABS. As a material, PLA has much less warping versus ABS. Additionally, a heated bed is not required to print it. PLA generally enjoys sharper details and corners compared to ABS without the risk of cracking or warping. PLA can also be printed at higher throughput speeds.
HIPS, High Impact Polystyrene, is very similar to ABS. They share a lot of the same characteristics and qualities. However, HIPS is used with different solvents versus ABS. Limonene is used with HIPS instead of Acetone for ABS. Since Limonene does not affect ABS, HIPS is commonly used as a supporting material. HIPS is versatile, economical, and impact resistant.
Wood (Please note net weight of 0.8 kg) is a new FDM filament that was developed to print wooden-like objects. The filament contains recycled wood with PLA and some binding polymers. Printing at lower temperatures will produce a brighter color, and if you adjust the print temperatures to be higher it will create a darker print. Adjusting the print temperature by as little as 10 degrees will vary the coloration giving the printed object a "grainy" look. The printed wood will appear rough and similar to Medium Density Fiberboard, known as MDF. Wood filament is less viscous compared to PLA or ABS during printing. Please add a little extra extrusion to the beginning of the print to help prevent dry extrusion. Also, increasing the retraction setting during slicing will reduce "leakage." The wood filament will appear delicate after print, so please allow the wood filament to set approximately thirty to sixty minutes after printing.
PVA (Please note net weight of 0.5 kg) is a water-soluble synthetic polymer. PVA is degradable and dissolves quickly in water. It is the perfect filament to use as support material for it's dissolvable properties. Generally, PVA is used in conjunction with PLA not ABS because it adheres well to PLA. The extrusion temperature difference can also be problematic with ABS. Importantly, PVA should not be allowed to sit at temperatures higher than 200°C for an extended period of time, known as pyrolysis. It will form jams which are extremely difficult to remove. Unlike PLA and ABS, you cannot remove the jam by increasing the temperature. Clearing the jam in the nozzle will often require it to be re-drilled or replaced altogether, so be careful!

•Fluorescent colors - The fluorescent colors will glow when UV light is shined on it. UV light is commonly known as black light.
•Conductive - The conductive black ABS filament is exactly what the name implies. The conductive filament can be used for anti-static, static dissipative, and conduction of electric current.
•Color Change by Temp - The color change filaments will change colors at 31°C (88°F). The filament is one color below 31°C, and when it is heated above 31°C, the filament will change to another color. Please see the video above for the color change effect.
