ABS or PLA filament, high quality.

These reels of thread are for 3D printing.

There are two main types of plastic used in 3D printing – PLA (Polylactic Acid or Polylactide) which is plant starch based, and ABS (Acrylonitrile Butadiene Styrene), which is petroleum based. Both PLA and ABS have pros and cons to them. One or the other may be better for an end-user’s situation. For example, ABS requires higher temperatures to extrude than PLA. That often requires that you use a hot plate to print on so the part does not cool too fast as it is being printed. PLA, on the other hand, frequently prints better if there is a fan blowing on the part to cool it down before it can droop
