Material comparison
| Material | Strength & toughness | Heat resistance* | Outdoor / UV | Detail | Best for |
|---|---|---|---|---|---|
| PLA | Stiff, can be brittle | Low (~55–60 °C) | Poor | Good | Visual prototypes, models |
| PETG | Tough, slightly flexible | Moderate (~70–80 °C) | Fair | Good | Everyday functional parts |
| ABS / ASA | Tough | Good (~95–100 °C) | ASA: very good | Good | Heat, automotive, outdoor |
| Nylon | Very tough, wear resistant | Good (varies by grade) | Fair | Good | Gears, hinges, snap-fits |
| Resin | Standard grades brittle | Varies by resin | Poor (standard) | Excellent | Small precise parts, fine detail |

How to choose in four questions
- Will it get hot? Above about 50 °C — a car interior, near a motor, in direct sun — rule out PLA.
- Will it live outdoors? Choose ASA.
- Does it flex, snap, slide, or take impacts? Choose nylon or PETG.
- Is it small with fine features or a smooth surface? Choose resin.
If none of those apply, PETG is a dependable default and PLA is the economical choice for parts that are just for looking at or checking fit.
Questions
What is the strongest 3D printing material you offer?+
For toughness and resistance to cracking, nylon is usually the strongest choice among our common materials. For stiffness and heat, ABS/ASA performs well. The right answer depends on how the part is loaded.
Which 3D printing material is best for outdoor use?+
ASA. It was developed as a UV- and weather-resistant alternative to ABS.
Which material gives the most detail?+
Resin, printed with SLA/DLP-style processes, captures the finest features and smoothest surfaces.
What if I'm not sure which material to pick?+
