Best Used For:

When Not To Use:

ABS (Acrylonitrile Butadiene Styrene)

210° – 240°C

Heated bed at 80°C or more


Extrudes well. Can be printed quickly and resists stringiness. It shrinks as it cools which can cause issues with the print lifting from the bed and layers cracking/splitting.

Strong, somewhat flexible; will bend rather than snap when put under pressure.

Mild odor.

Objects that might be dropped or placed in hot environments.

Not for use on a non-heated bed or in a cool or drafty environment. Large or very long prints have a high likelihood of warping.

PLA (Polylactic Acid)

190° – 215°C

40° – 60°C


Is sticky and can expand, which can create jamming in the hot-end. Lays on the print bed with little to no shrinkage. Can be used with open framed printers with little/no fear of warping, cracking, or prints lifting from the bed.

Strong, but more brittle than other plastics.

Mild, sweet aroma.

Biodegradable items; good for boxes, gifts, prototypes.

Parts that need to hold up in 60°C temperatures (prints will sag); parts that will be dropped frequently, or parts with thin portions (will break after bending slightly).

PETG (Poly-Ethylene Terephthalate Glycol)

230° – 260°C

70° – 100°C


The layer adhesion is excellent. Expect less trouble with warping or shrinking of prints. Material is highly impact resistant. Overheating regular PET makes it hazy and brittle. Not with PETG filament: The added glycol prevents the material from crystallizing and becoming breakable.

Strong, temperature-resistant, more durable than PLA, easy to print like PLA, impact-resistant.

No smell.

Objects that could be dropped or if dimensional stability is critical.

No heated bed or parts that must withstand high temperature.

TPU (Thermoplastic Urethane)

220° – 245°C

40° – 60°C


(Below Room Temperature)

Layer adhesion is normally excellent. Depending on the hardness of the TPU, the printability can range from easy to difficult. Lower hardness means more flexibility (our flexible material is 85A hardness and our semi-flexible material is 90A hardness).

Good resistance to oils, solvents, oxidation and ozone.

Light to no smell.

Flexible objects like phone cases.

If rigidity is a key characteristic or if the printer is not setup to handle flexible material.

PLA/PHA (Polyhydroxyalkanoates)

190° – 230°C

60° – 90°C

50° – 60°C

Dimensional stability that is similar to PLA and PETG with flexibility characteristics like ABS and PETG. Great layer adhesion and warping of print is low.

Somewhat flexible, durable, easy to print.

Mild, sweet aroma.

Objects that could be dropped.

No heated bed or parts that must withstand high temperature.
