PETG Filament

PETG is a tough, slightly flexible 3D printer filament that handles more heat than PLA. It holds its shape to about 75°C, resists moisture and most chemicals, and prints without an enclosure. We stock PETG in 1.75 mm on plastic spools in standard, matte, translucent, metallic, carbon fibre and glass fibre filled grades.

Types of PETG we stock

• Standard PETG and PETG V2 for functional parts.
• Matte PETG for a flat finish with PETG toughness.
• Translucent and metallic PETG for light pipes, covers and decorative parts.
• PETG CF and PETG GF for stiffer, more stable parts.
• Wood and marble PETG for effect prints.

What PETG is good for

PETG suits brackets, enclosures, garden and garage parts, printer parts and anything that takes knocks. It bends before it snaps, where PLA cracks. It is not UV stable over years in full sun, so for long term outdoor parts ASA is the better pick.

Print settings

PETG absorbs moisture and strings when damp, so dry it if prints turn stringy. Free slicer profiles are available, and data sheets are in the TDS library.

Common questions

Is PETG stronger than PLA?

PETG is tougher than PLA but not stiffer. PETG flexes and absorbs impact where PLA cracks, and PETG keeps its shape to about 75°C against roughly 55°C for PLA. PLA is the stiffer of the two, so it wins for rigid parts kept at room temperature.

What temperature should I print PETG at?

PETG usually prints with the nozzle at 230 to 250°C and the bed at 70 to 85°C. Run the part cooling fan at 30 to 50 percent. Too much cooling weakens the bond between PETG layers, and too little causes sagging on overhangs.

Does PETG need an enclosure?

PETG does not need an enclosure. PETG warps far less than ABS or ASA and prints well on an open printer. An enclosure can help very large PETG parts in a cold room, but most PETG prints do not need one.

Why is my PETG stringing?

PETG strings mostly because it has absorbed moisture or the nozzle is too hot. Dry the PETG spool, drop the nozzle temperature by 5 to 10°C and check retraction settings. Fresh, dry PETG on a tuned profile prints with very little stringing.
