PLA vs PETG for beginners: which filament should you use?

Short answer: start with PLA. Move to PETG when you need a part that is tougher, bends instead of snapping, or has to survive heat and sun. Here's why, and how to switch without headaches.

When to pick each

• Pick PLA for your first prints, decorations, figures, cosplay props, organizers and anything that stays indoors at room temperature.
• Pick PETG for parts that bend, get knocked around, sit in a car or outdoors, or get near warm water.
• Pick neither yet if you need something that touches food regularly; see the food-safety section below.

The quick comparison

PLA and PETG are the two most popular filaments (the plastic "string" a filament printer melts). Both are easy compared with materials like ABS or nylon, and neither needs an enclosed printer. The temperatures below are typical ranges; always use the numbers printed on your spool, because brands differ. To find the exact sweet spot for your spool, print a temperature tower.

Why PLA is the best first filament

PLA prints at low temperatures and barely shrinks as it cools, so prints stay flat on the bed. It forgives a slightly-off first layer, it bridges and overhangs well (it can print across gaps and at angles without drooping much), and it gives crisp detail. It also comes in the widest range of colors and finishes, like silk, matte and glow-in-the-dark.

Every printer's default profiles are tuned for PLA first, which means fewer settings to think about while you learn. That's why our first print checklist starts with plain PLA.

Where PLA falls short

• Heat. PLA starts to soften at roughly 55 to 60 °C. A dashboard in summer, a dishwasher or a spot next to a heater can make it sag or bend.
• Brittleness. PLA is stiff, which is great for display pieces, but clips and snap-fit parts can crack when bent repeatedly.
• Long outdoor use. Sun and heat wear it down faster than PETG.

What PETG is good at

PETG is a close cousin of the plastic used in drink bottles. Prusa, which uses PETG for parts of its own printers, describes it as tough, temperature resistant and still suitable for beginners. It is a great choice for:

• Functional parts: brackets, clips, hooks and mounts that get bent or knocked
• Things that live in a car, garage or garden
• Parts that touch water or mild cleaning products

For parts that will sit in strong sun for years, more experienced makers often use ASA instead, but ASA is harder to print and usually needs an enclosure.

What makes PETG trickier

Stringing

PETG is stickier and runnier when melted, so it leaves more fine "hairs" between parts of a print. Use your slicer's PETG profile (the slicer is the program that prepares your model for printing), keep the spool dry, and see our stringing guide if it gets bad.

It can stick too well

On a smooth PEI build plate, PETG can bond so strongly that it tears pieces out of the surface when you remove the print. Prusa specifically recommends its textured (powder-coated) or satin sheets for PETG. If you only have a smooth plate, wipe on a thin layer of glue stick first; it acts as a release layer. Textured PEI plates, which many printers ship with, usually work fine with no glue.

Less squish on the first layer

PETG doesn't like being pressed hard into the bed. If the nozzle is very close, it tends to pick plastic up and drag blobs around. Many people raise the nozzle very slightly for PETG compared with PLA. If you're not sure what that means, read how to level a 3D printer bed, and if PETG won't stick at all, work through first layer not sticking.

Cooling and overhangs

PETG needs a bit less cooling fan than PLA, and overhangs and bridges droop more. Your slicer's PETG profile already accounts for this, which is one more reason to start with the default profile and not copy PLA settings.

Can your printer print PETG?

Most printers sold in the last few years can. Check your manual for:

• Maximum nozzle temperature: you want at least about 250 °C. Some older or budget printers have a plastic tube (PTFE) running right down to the nozzle and aren't meant to run much above 240 °C for long periods.
• Maximum bed temperature: about 80 °C or more is comfortable. For example, Bambu Lab lists a maximum bed temperature of 80 °C for the A1 mini and 100 °C for the A1, and lists PETG as an "ideal" material for both.
• Build plate: textured PEI, or smooth PEI with glue stick.

How to switch from PLA to PETG

1. Select the PETG profile in your slicer, ideally the one that matches your spool's brand.
2. Swap the filament using the printer's unload and load functions, and let it push out plastic until the new color comes out clean.
3. Check the plate: textured PEI, or glue stick on smooth PEI.
4. Print something small first, like a small box or hook, and watch the first layer.
5. If it strings or pops, dry the spool. Bambu Lab's drying guidance for PETG is about 60 to 65 °C for around 8 hours in a convection-style dryer; follow your dryer's and spool maker's instructions. Our filament drying guide covers the details.

What about "food safe"?

You'll see PETG described as food safe because of drink bottles. Be careful: a 3D-printed object has tiny gaps between layers where bacteria can hide, and nozzles, colorants and additives vary. For anything that touches food, check the filament maker's own statement and treat printed parts as single-use or decorative unless you know otherwise.

Our recommendation

• Your first spool: basic PLA, in a light color (it's easier to see what's going on).
• Your second spool: PETG, once you can reliably get a good first layer.
• Keep both around: PLA for decorative and quick prints, PETG for anything that needs to take a beating or handle heat.
