pla
Polylactic
Acid
The most common material used in 3D printing. Very versatile, but least strongest material compared to the rest. A great material for fun things like magnets or molds.
petg
Polyethylene
terephthalate
glycol
The same material water bottles are made from. This material has a good combination of strength, bending and abrasion resistance. Also the only material that is food safe. Ideal for cookie cutters among many other things.
ABS
Acrylonitrile
butadiene
styrene
This material is the same used for bumpers for cars. It has a very good heat resistance and strength. A bit better material compare to PETG, but a lot more difficult to print.
pc
polycarbonate
Highest abrasion and impact resistant material off them all. The only challenge is a high difficulty to printing. Strongest material compared to the rest and ideal for mechanical parts.
tpu
Thermoplastic
polyurethane
The only flexible material available. This has a very high temperature reistance while also having a bending capability. Due to it's properties it is the hardest material to print.
Nylon
taulman
bridge
A very flexibile durable material. The only issue is it has a very low strength and stiffness. A pro is a high resistance to chemicals. With this material being such a low strength it can be a real challenge to print with this material.
