There are pros and cons to using both ABS and PLA and which one you choose will depend largely on the model you are making, it\'s application and the finish you are looking for. PLA can be melted at lower temperatures and the odour when printing is slightly more pleasant than ABS. However, because PLA melts at lower temperatures, it can be prone to drooping if left in a really warm place for extended periods, especially if the model has thin, unsupported parts.
