FFF 3D printing can use a wider range of materials, like HIPS (similar to ABS), PET-G and PET, but are harder to be found. The world market is moving fast and it constantly add new opportunities. 3D printers, on their side, update themselves in order to be able to print all the available filaments.
PLA and Nylon, anyway, can also differ in their composition, as they can be additioned with other materials.
Here are a few examples:
WOOD PLA: this filament has wood fibers inside and get a very nice brownish finishing. Very smooth, when just printed a nice smell of real wood can be felt.
GLASS PLA: the name says it all. Translucent and very strong, the finishing is not completely transparent due to the part of PLA still present.
CARBON FIBER: both PLA and Nylon can be additioned with this component. This adds strenght and a better finishing to Nylon, while it is lighter than standard PLA.
FLEXY: this mixture of more thermoplastic materials ends in being flexible and elastic. It has a big shape memory and does not require high temperatures to be printed.
Always choose high quality special filaments like FABtotum’s ones.
