If you own an FDM printer, three names come up in almost every "what should I print with?" debate: PLA, ABS and PETG. They're the three workhorses of desktop 3D printing — but they behave nothing alike. Get the material wrong and you'll fight warping, clogged nozzles or parts that melt on a sunny windowsill. This guide gives you a clean, buyer-first comparison so you can stock the right spools.
What is PLA (Polylactic Acid)?
PLA is the default for a reason. It prints at a low 190–220 °C, barely warps, and gives off little more than a faint sweet smell. Being corn-starch-derived, it's also the most environmentally friendly of the three. The trade-off is mechanical: PLA is brittle and softens around 60 °C, so it's a poor choice for parts that take heat, load or impact.
Best for: prototypes, display models, toys, jigs for light use, and high-speed draft work. See our White PLA 1.75mm 1kg spool →
What is ABS (Acrylonitrile Butadiene Styrene)?
ABS is the tough one. It prints hotter (230–250 °C) on a heated bed (90–110 °C), and ideally inside an enclosure — without one it warps and cracks as it cools. It gives off noticeable fumes (print in a ventilated space), but it pays you back with high impact strength, a service temperature around 100 °C, and fantastic post-processing: you can sand it and vapor-smooth it with acetone for a glossy, injection-molded look.
Best for: durable functional parts, automotive and enclosure components, Lego-style interlocking prints, anything that needs to survive heat or abuse. We currently focus our catalog on PETG, PLA and Silk PLA, but ABS is available as an OEM/ODM custom run for resellers and print farms.
What is PETG (Polyethylene Terephthalate Glycol)?
PETG is the all-rounder that stole ABS's crown for most users. It prints almost as easily as PLA but adds real strength, impact resistance and a service temperature up to ~80 °C. It's slightly hygroscopic (seal it when not in use, dry before long prints) and can string a little if retraction isn't tuned — but for functional parts it's the sweet spot. It's also food-contact-adjacent and widely used for brackets, enclosures and outdoor prints.
Best for: mechanical parts, brackets, jigs, enclosures, outdoor and semi-durable prints. Browse all 28 PETG colors →
PLA vs ABS vs PETG: the quick comparison
| Factor | PLA | ABS | PETG |
| Print temp | 190–220 °C | 230–250 °C | 220–250 °C |
| Bed temp | ~60 °C | 90–110 °C | 70–85 °C |
| Print difficulty | Very easy | Hard (needs enclosure) | Easy–medium |
| Strength / toughness | Low (brittle) | High (impact) | High |
| Heat resistance | ~60 °C | ~100 °C | ~80 °C |
| Warp tendency | Very low | High | Low–medium |
| Fumes / ventilation | Minimal | Strong (ventilate) | Low |
| Post-processing | Limited | Sand + acetone smooth | Sand, light smooth |
| Best for | Prototypes, decor | Durable functional parts | Functional + semi-durable |
So which one should you choose?
A practical rule of thumb:
- PLA — if it just needs to look right, sit on a desk, or be printed fast and cheap.
- PETG — if it has to survive being used, dropped, washed or heated to ~80 °C. This is the default for most "real" parts.
- ABS — if you need maximum impact strength, ~100 °C heat resistance, or an acetone-smoothed finish, and you can print enclosed.
Most print farms keep PLA and PETG on hand at minimum, because different orders need different materials — and because a deep color range is what drives repeat business. Our 3D printing filament catalog covers 43 factory-direct SKUs: 28 PETG colors, 12 PLA colors and 3 Silk PLA finishes, all 1.75 mm / 1 kg, ±0.02 mm tolerance, vacuum-sealed. ABS and other engineering materials are available as custom OEM/ODM runs.
Why buy CHUSIPRINT filament?
We laser-gauge every spool to ±0.02 mm, vacuum-seal it at the factory, and keep batch specs stable across reorders. That means fewer nozzle clogs, more predictable first layers and less time re-tuning profiles — whether you run one printer or fifty.
