A brief characterics for 3D ABS & PLA filament:

 

 

 

ABS (Acrylonitrile butadiene styrene) is an oil based filament and has a higher melting point than PLA. ABS filament is commonly used in 3D printing. It has the following characteristics:

 

• Softer than PLA, but high strength, good toughness;
• Density is small, when printing larger volume model lighter, save money;
• Cost-effective, can be processed in wide range temperature;
• Accurate diameter: 3.0/1.*5mm, variations + /*0.*5mm, roundness +/*0.*3mm;

 

PLA (Polylactic acid) is thermoplastic aliphatic polyester made of renewable resources like corn or starch. Its extrusion-temperature is much lower than ABS, and most often doesn’t require a heated bed. It has the following characteristics:

 

• Good toughness high strength, high stiffness ;
• No block nozzle, good stick hot bed, a smooth PLA used
• Can be processed at **5 degrees
• Low shrinkage, thermoforming dimensional stability
• Accurate diameter: 3.0/1.*5mm, variations + /*0.*3mm, roundness +/*0.*2mm.
