Short answer: choose PLA for easy, detailed everyday prints; PLA+ when you want a tougher general-purpose part; and PETG for functional parts that need better toughness, moisture resistance or temperature performance.
The best filament is not simply the strongest or most expensive option. It is the material that suits the part, your printer and the environment in which the finished print will be used. This guide will help you make that choice without overcomplicating it.
PLA, PLA+ and PETG at a glance
| Material | Best for | Main advantage | Consider before buying |
|---|---|---|---|
| PLA | Beginners, models, décor, prototypes and detailed prints | Easy to print with low warping | Not the first choice for hot environments or heavily loaded parts |
| PLA+ | Tougher prototypes, brackets, toys and everyday functional parts | A practical balance of printability and toughness | “PLA+” formulations differ between manufacturers; follow the spool profile |
| PETG | Functional parts, containers, workshop items and parts exposed to moisture | Tough, durable and more temperature resistant than standard PLA | Can string more than PLA and needs careful first-layer setup |
Choose PLA if easy, reliable printing matters most
PLA is the safest starting point for most FDM printer owners. It generally prints at lower temperatures, warps less than many engineering materials and produces crisp detail. That makes it well suited to display models, school projects, concept prototypes, organisers and decorative parts.
Choose PLA when the print will live indoors and will not be exposed to substantial heat, weather or repeated mechanical stress. It is also a sensible material for testing a design before committing to a more demanding filament.
Choose PLA+ for a tougher everyday option
PLA+ is a modified PLA formulation intended to improve properties such as toughness or layer adhesion while retaining much of PLA’s approachable printing behaviour. It is useful for brackets, enclosures, toys, jigs and other everyday parts where standard PLA may feel too brittle.
There is no single universal PLA+ formula. Temperatures and performance vary by brand, so use the settings printed on the spool or supplied by the manufacturer rather than assuming every PLA+ prints identically.

Choose PETG for functional, moisture-exposed parts
PETG is a strong general-purpose choice when durability matters more than the easiest possible print. It is often selected for workshop organisers, protective housings, brackets, containers and functional components. It typically offers greater toughness and temperature resistance than standard PLA.
PETG can produce fine strings if the filament is damp or retraction and temperature are not tuned. Start with the filament manufacturer’s recommended profile and adjust one setting at a time.
Which filament should you order?
- Your first spool: PLA.
- A stronger everyday print with familiar handling: PLA+.
- A functional part exposed to moisture or moderately higher temperatures: PETG.
- A display model or colour-focused print: PLA, matte PLA or silk PLA.
- A flexible item: consider TPU rather than these three materials.
Before you buy
- Confirm the filament diameter supported by your printer; most current desktop FDM machines use 1.75 mm.
- Check that your hotend and build plate can reach the recommended temperatures.
- Consider the finished part’s heat, sunlight, moisture, and load exposure.
- Keep the spool sealed and dry when it is not in use.
- Use the manufacturer’s profile as your starting point.
