ABS is tough and heat-tolerant: car interiors, enclosures near hot components, parts that need sanding or acetone smoothing. It needs an enclosed printer and more care, so the setup cost is worth it only when heat or finishing is the point.

· CAR-INTERIOR AND HOT-MACHINE PARTS
· PROTOTYPES THAT TAKE SANDING OR ACETONE SMOOTHING

PLA
৳5/G · MACHINE ৳35/H · MIN JOB ৳150
PLA is the default. Strong, easy to print, and fine for almost everything that lives indoors at room temperature. If you don't know what to pick, pick PLA.

৳5/G · MACHINE ৳35/H · MIN JOB ৳150
TPU is rubber-like: flexible, tough, and shock-absorbing. It costs more and prints slower, so use it where flex is the point.
