The difference between ABS and PLA

 The most popular items -3D printer launched in 2013, following many 3D printing lover and enthusiastic about printing all kinds of fantastic products. Do you know the difference between the ABS filament and PLA filament, both of which are the materials of 3D printing?

The characteristics of PLA

PLA is a biodegradable material which made from renewable plant resources first, in turn, made of starch materials. It has good mechanical and physical properties. PLA is suitable for blow molding, thermoplastic and other processing methods, for Which can be widely applied. PLA filament is its best application.

The characteristics of ABS

ABS resin is the largest output, the most widely used polymers. It has good mechanical properties. ABS plastic is opaque; light ivory, non-toxic and tasteless. ABS filament also have the similar feature.

The difference between ABS and PLA material in printing

When printing, the PLA sent cotton candy flavor, no pungent smell is ABS.
Usually the processing temperature ABS is higher than PLA.
PLA has low shrinkage, running well, and even larger modules.
PLA whose surface is gloss and colorful, have a low melt strength.
ABS is a kind of amorphous crystallization. Heating will slowly convert gel liquid, the change of the stateless. PLA like frozen water, directly from solid to liquid. Since there is no phase change, ABS is not the heat energy absorbed suction nozzle, the nozzle clogging the risk bigger than PLA.
