Advantages
  • The most economical and fastest filament to print
  • High dimensional stability, does not warp
  • Glossy surface and a wide range of colors
  • Plant-based biopolymer
  • As easy as PLA, much more durable
  • Resistant to water and many chemicals
  • Transparent option
  • High elongation: bends without breaking
  • Resists impact and heat
  • Easy post-processing: sanding, painting and acetone vapor smoothing
  • Proven material in automotive and electronics
Limitations
  • Low heat resistance (~53 °C)
  • Brittle under impact
  • Can degrade in prolonged sunlight
  • Tendency for fine stringing on the surface
  • Lower heat resistance than ABS
  • Hard to sand
  • Requires an enclosure; prone to warping
  • Yellows and becomes brittle under UV (ASA is preferred outdoors)
  • Odor and emissions while printing

The mint value shows the highest among the selected materials. Values are typical averages.

Selection guide

Which filament for which job?

Good to know

Choosing a filament: frequently asked questions

Is PLA or PETG better?

It depends on the use. PLA is the easiest and most economical filament to print; it is ideal for visual prototypes and models but softens above about 55 °C. PETG is tougher and more resistant to impact, moisture and chemicals; it is usually the better choice for functional parts used every day.

What is the strongest filament?

Where stiffness and strength are needed together, carbon fiber reinforced nylon (PA-CF) and PPA-CF stand out. Where impact strength and toughness are needed, PC and unreinforced nylon are better. TPU is preferred for parts that must flex without breaking.

Which filament is heat resistant?

Heat deflection temperature roughly increases from PLA to PETG, ABS and ASA, then carbon fiber reinforced nylons. For applications above 100 °C, reinforced engineering filaments such as PA-CF, PPA-CF and PPS-CF are considered.

Which filament should be used outdoors?

ASA is the best choice for parts exposed to sun and UV light for long periods; it keeps its color and surface. PETG also works well for short and medium-term outdoor use. PLA and ABS can degrade outdoors over time.

Which filament is flexible?

TPU 95A is the most common filament with rubber-like flexibility. It is used for gaskets, bumpers, belts, cases and vibration dampers; it can stretch several times its length without breaking.

What is the difference between ABS and ASA?

Both are engineering plastics that resist heat and impact. ASA is the UV-resistant relative of ABS: it does not yellow or fade in the sun. ABS is preferred for indoor parts and ASA for outdoor parts.

Why are the values in the table not exact?

The values are typical figures compiled from manufacturer datasheets and literature. In 3D printing, strength varies with print orientation, layer height, infill and brand. For critical parts our engineers verify with a test part if needed.
