- [Female Voice] 3D printing metal for an application might seem to be the only option if you need a very strong part. If you don't want to invest in a printer that can lay down continuous carbon fiber and you're reluctant to abrade your nozzle using filament with chopped fiber what are your options for a strong part? - [Male Voice] PLA is the most common material for filament printing because it's easy to work with. It's pretty stiff but it can be brittle and snap. It also has a tendency to creep under constant force. It does this pretty slowly at room temperature but it can happen alarmingly quickly in hot weather. There are other materials that have more advantageous properties though. - [Female Voice] Filaments that create parts that can withstand a lot of force can be challenging to print since they tend to require high printing temperatures. This means they tend to cool during the print and to warp up from the bed.…
