PLA is harder than ABS, melts at a lower temperature (around  180Â°C to 220Â°C), and has a glass transition temperature between 60-65 Â°C, so is potentially a very useful material. It does exhibit higher friction than ABS however which can make it difficult to extrude and more susceptible to extruder jams.
Best Answer: Melting temp is when DNA strands separate, annealing temp is the temp where complimentary strands recombine (or anneal).The importance is this: In PCR, the temperature is cylced high to low, and a DNA polymerase that is heat-resistant is used so that it is not denatured at higher temps.f you don't reduce it to that lower temperature, the primers can never hydrogen bond with the DNA and cause extension. and this annealing temperature is CRUCIAL for the PCR to work.
