PETG Filament 1.75 mm

Tough, chemical-resistant 3D printer filament for functional parts

  • 1.75 mm ± 0.05 mm
  • 1 kg / 2.2 lb spool
  • Up to 300 mm/s
  • AMS compatible
  • Ships from the USA

PETG is the 3D printer filament you reach for when a print has to do a job, not just look good. It combines the strength of an engineering material with the printability of PLA: it stretches instead of snapping, shrugs off water and most chemicals, stays dimensionally stable outdoors, and prints reliably on an open-frame printer without an enclosure. The Fremover PETG we stock is rated from 50 to 300 mm/s and is AMS compatible, so it fits straight into modern multi-material workflows. From protective housings and brackets to watertight containers and transparent covers, PETG 1.75 mm bridges the gap between easy printing and parts you can actually rely on — and you buy it in a custom pack, mixing any colors you want in a single order.

What Makes PETG Filament Different

High-Speed Ready

Rated from 50 to 300 mm/s and fully AMS compatible. It holds a steady melt flow at speed, so fast machines don’t under-extrude on long walls or lose gloss consistency on large surfaces.

That means you can actually use the throughput your printer is capable of instead of slowing everything down for the filament.

Ductile & Chemical Resistant

PETG stretches before it fails — 18.3% strain at break against roughly 5% for typical PLA. Parts flex under load and absorb handling instead of cracking, which makes it ideal for enclosures, clips and brackets.

With only 0.12% moisture absorption and strong resistance to water, oils and diluted household chemicals, it holds up in workshop and outdoor environments where PLA degrades.

Low Warp, No Enclosure

Unlike ABS or ASA, PETG stays flat on the bed without a heated chamber. Large, wide parts finish without lifted corners, even on an open-frame printer.

A 1.75 mm diameter held within ±0.05 mm keeps extrusion predictable from the first layer to the last meter of the spool.

PETG vs. PLA: Which Filament Should You Choose?

Where PETG Wins

  • Ductile — 18.3% strain at break vs. roughly 5% for PLA
  • Higher heat tolerance (70°C heat deflection)
  • Resistant to water, oils and most household chemicals
  • Very low moisture absorption (0.12%)
  • Excellent layer adhesion for watertight parts
  • Available in true transparent colors

Where PLA Falls Short

  • Brittle — cracks under sudden load
  • Softens at relatively low temperatures
  • Absorbs moisture and degrades outdoors
  • Poor chemical resistance
  • Not suited for load-bearing functional parts
  • Limited long-term durability

PLA is still the easiest material to print and the right pick for models, display pieces and quick prototypes. PETG is what you move to the moment a part has to carry load, live outdoors, hold liquid or take repeated handling. Because PETG prints without an enclosure and warps far less than ABS or ASA, it is the most accessible step up into functional 3D printing — no hardware upgrade required. One caveat worth knowing before you buy: with a 65°C Vicat softening point, PETG is a clear step above PLA in heat resistance but not a substitute for ABS or ASA in genuinely hot environments.

What People Print With PETG Filament

01

Functional Parts

Brackets, mounts, jigs, hinges and replacement parts. PETG holds tight tolerances while staying ductile enough to be screwed, clipped and stressed without cracking — the sweet spot between printability and mechanical performance.

02

Outdoor & Wet Use

Garden fixtures, hose adapters, planters, outdoor enclosures. With 0.12% moisture absorption PETG doesn’t swell or degrade the way PLA does, and its strong layer bonding makes it easy to print watertight vases and containers in spiral mode.

03

Transparent Prints

Light diffusers, covers, display cases and lamp shades. Transparent PETG prints with a clean, glossy finish — raise the temperature slightly and slow down for the clearest possible results.

How to Get Perfect PETG Prints on Your First Try

PETG has a reputation for being fussy. It isn’t — it just wants slightly different settings than PLA. Change these five things and your first spool will print beautifully.

  • Dry it first: PETG picks up moisture from the air. A blast dry at 60–80°C eliminates the popping, bubbles and fine hairs that usually get blamed on bad settings.
  • Start hot, then walk it down: Begin at 250°C. If you see stringing, drop 5°C at a time; if layers look weak, go back up. The usable window runs all the way to 280°C.
  • Keep the fan on: The data sheet calls for 100% part cooling. Good airflow is what gives you clean overhangs and crisp detail at speed.
  • Slow the first layer: Print it at 20–25 mm/s with a slightly larger Z gap so the filament doesn’t bond too hard to the bed.
  • Skip the glue on smooth PEI: PETG sticks extremely well. Use a textured plate or a thin release layer so you don’t chip the build surface when removing the part.

Every spool ships sealed and packed with silica gel, so you start from a dry, consistent baseline instead of fighting filament that already absorbed moisture sitting in a warehouse.

How to Print PETG: Settings and Troubleshooting

Getting Started

  • Keep the spool sealed until you print, and blast dry at 60–80°C if it has been open for a while
  • Start at 250°C nozzle and 80°C bed, then adjust in 5°C steps
  • Run part cooling at 100% — PETG needs the airflow for clean overhangs
  • Slow the first layer to about 20 mm/s and raise the Z offset slightly
  • Use a textured plate or a light release agent on smooth PEI to protect the surface

Advanced Techniques

  • For stringing, lower the nozzle 5°C at a time and keep retraction speed near 40 mm/s
  • For watertight parts, print in vase mode or use 5–6 perimeters with 0.2 mm layers
  • For maximum clarity in transparent colors, print hotter and slower with reduced cooling
  • Increase flow rate 2–3% if you see gaps between perimeters at high speed
  • Any nozzle from 0.2 to 1.0 mm works — go to 0.6 mm for faster functional parts
Storage Tip: PETG absorbs very little water compared to nylon or TPU (0.12%), but it still picks up enough to affect surface quality. Once opened, keep the spool in a dry box or a resealable bag with fresh silica gel. Every spool ships sealed with desiccant for exactly this reason.

PETG Filament FAQ

Is PETG harder to print than PLA?

Only slightly, and only until you dial it in. PETG needs a hotter nozzle and a hotter bed than PLA, and it sticks to the build plate much more aggressively. Once those settings are right it prints just as reliably — and unlike ABS or ASA it doesn’t need an enclosure. Most stringing complaints come from wet filament, not from the material itself.

What temperature should I print PETG at?

The data sheet gives a window of 230 to 280°C at the nozzle and 70 to 90°C at the bed. A good starting point on most printers is 250°C and 80°C. If you see stringing, drop the nozzle 5°C at a time; if layers separate or look weak, go back up. Part cooling should run at 100%.

Do I need to dry PETG filament before printing?

Spools ship sealed with silica gel, so a fresh one is ready to print. If a spool has been sitting open for more than a few weeks, blast dry it at 60–80°C. Signs of wet PETG include popping or crackling during extrusion, fine hairs across the print and a rough, matte surface.

How much heat can a PETG part take?

The data sheet lists a Vicat softening point of 65°C and a heat deflection temperature of 70°C at 0.45 MPa. That is comfortably above PLA and fine for most indoor and outdoor use, but PETG is not a high-temperature material — for parts that sit on a sunlit dashboard or next to a heat source, ASA or ABS is the better choice.

Is PETG better than PLA for outdoor use?

Yes, clearly. PLA absorbs moisture, becomes brittle in UV light and softens in summer heat, so outdoor PLA parts tend to fail within a season. PETG absorbs only 0.12% moisture, tolerates weather far better and keeps its mechanical properties outdoors. For parts in constant direct sun over several years, ASA is the most UV-stable option of all.

Is PETG filament food safe?

PETG as a raw polymer is widely used in food packaging, but a 3D printed part is a different story: layer lines create microscopic grooves where bacteria can grow, and the nozzle, extruder and previous filaments can introduce contamination. For anything that touches food repeatedly, use a food-safe coating or a removable liner, and hand wash only.

Will this PETG work with my 3D printer?

It is 1.75 mm filament and works with any FDM/FFF printer that reaches 250°C at the nozzle and around 80°C at the bed — which covers virtually every modern machine, including Bambu Lab, Prusa, Creality and Anycubic. It is AMS compatible and runs on nozzles from 0.2 to 1.0 mm. If you’re unsure about your model, write to sales@fremover.net.

Can I really print PETG at 300 mm/s?

The data sheet rates the material from 50 to 300 mm/s. On a high-flow hotend with a properly tuned machine you can reach the top of that range. On an older stock printer the limit will be your hotend, not the filament — in that case 60 to 100 mm/s still gives excellent results.

How do I buy it — can I mix colors and materials?

Yes. PETG is sold in custom packs rather than one spool at a time: you choose how many spools you want and pick any combination of colors, and you can mix in other materials such as PLA+, TPU or ASA in the same pack. Build your pack on the bundle page and the price is calculated per spool, with free shipping within the contiguous USA.

Why Buy PETG Filament From Fremover

PETG is the most practical filament in the FDM world: strong enough for real parts, forgiving enough to print on any machine, and stable enough to live outdoors. It is the material most makers move to right after PLA, and the one that stays on the shelf permanently once they do.

Three things make these spools worth buying: they arrive sealed with silica gel so you never fight moisture out of the box, they hold a 1.75 mm diameter within ±0.05 mm for predictable extrusion, and every spool comes backed by a published technical data sheet so you know exactly what you are printing. Everything ships from the USA and is sold in custom packs, so you can mix colors and materials in one order instead of paying for spools you don’t need.
