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.
So how hot does it really need to be in order to do this, and what type of lighter would you have to use? The average melting point of glass is somewhere around 1500 degrees Celsius. This is certainly hotter than most lighters get, and it would take quite a bit of time to heat the glass to this point. If you are looking to melt glass, however, you will find that you have to choose lighters that can offer a sustained flame that burns at a very high temperature.
