Is PETG better than PLA?

For anything functional, usually. PETG survives heat to around 80C where PLA softens near 60C, and it bends rather than snapping. PLA is easier to print and gives crisper detail, so it stays the better choice for display pieces.

Can I print PETG on the same printer as PLA?

Yes. PETG needs a hotter nozzle and a hotter bed but no enclosure, so any printer that runs PLA will run PETG. Expect to spend a little time on stringing, which is the one thing PETG is genuinely fussier about.

Why does PETG string so much more than PLA?

Mostly moisture. PETG is hygroscopic and PLA barely is, so a spool left open picks up water that boils at the nozzle and leaves threads. Dry the filament before adjusting retraction.

Which is stronger, PLA or PETG?

PLA is stiffer and PETG is tougher, which are different things. PLA resists bending harder but fails suddenly; PETG flexes and absorbs impact. For a part that gets knocked about, PETG lasts longer.

Is PLA or PETG better for outdoor use?

PETG. PLA is not a serious outdoor material: it softens in a hot car and degrades in sunlight. PETG handles both far better, though ASA beats it for anything permanently exposed.

PLA vs PETG: which to use.

Pick the wrong filament and the part fails. Pick the right one and it works for years. PLA and PETG cover most of what hobbyists print. This page shows you which to use for every situation.

USE PLA WHEN

Use PLA when heat and strength do not matter.

PLA works well for anything that stays indoors and stays cool. It prints at the lowest temps, requires no heated bed, and forgives almost every tuning mistake. That makes it ideal for learning a new printer.

Indoor decorative prints, models, and figures.

Rapid prototypes where strength does not matter.

Anything that will not see heat above 60°C. Leave PLA in a hot car and it warps.

Dialing in a new printer. PLA is the most forgiving material available.

USE PETG WHEN

Switch to PETG when the part has a job to do.

PETG is the step-up material for parts that actually need to hold up. It handles more stress, more heat, and more flex than PLA, without needing an enclosure.

Functional parts that need to hold together under stress: brackets, clips, mounts.

Anything that might get warm: engine bay accessories, outdoor brackets.

Snap-fit parts that need to flex without snapping.

Food container lids. Check that your brand is food-safe certified. Not all PETG is.

PETG · COMMON ISSUES

Fix these three PETG issues before you waste a spool.

Sticking too hard to the glass bed

PETG bonds aggressively to bare glass and will chip it when you remove the print. Fix: apply a thin layer of Elmer's glue stick to the bed before printing, or switch to a PEI sheet. PEI releases PETG cleanly once the bed cools.

More stringing than PLA

PETG strings more than PLA. Some thin wisps are normal. For heavy cobwebbing: reduce print temp by 5°C, increase travel speed, and enable combing mode in your slicer. See our stringing fix guide.

Rough, bubbly top surface

Rough surfaces often mean wet filament. PETG absorbs moisture within a few days in humid air. Dry it at 65°C for 4 to 6 hours before printing. See our filament drying guide.

PETG LIMITS

Where PETG falls short.

High heat above 80°C. Use ASA or ABS for those applications.

Ultra-fine detail. PLA resolves sharper edges at the same layer height.

Chemical resistance in harsh solvents. ABS handles more chemicals than PETG.

So which should you buy?

Choose PLA if

180-220°C nozzle · 50-60°C bed · no enclosure

Display models
Prototypes
Toys and figures

The catch: Parts soften around 60C, so a print left on a dashboard will sag. If the part needs to survive heat, move to PETG or ABS rather than trying to tune PLA.

Typical price $15-30 per 1 kg spool. Drying is rarely necessary.

Choose PETG if

Functional parts
Outdoor fixtures
Food-adjacent containers

The catch: Stringing between towers. Drop the nozzle 5C at a time and raise travel speed before you touch retraction distance.

Typical price $18-30 per 1 kg spool. Needs drying before use.

Before you order either

Buy vacuum-sealed with desiccant, and read how to dry filament before the first failed print rather than after it.
Check the published diameter tolerance. ±0.02mm is good; ±0.05mm shows up as inconsistent extrusion whatever you paid.

Not printing it yourself?

If you would rather have the part arrive than pick a filament, upload the model and get a price in both materials.

FDM only, up to 220mm per side, shipping within the United States. Accepts STL, 3MF, STEP, OBJ.
