PLA and nylon are far apart. PLA is the easy, rigid filament for models. Nylon is the wear and heat specialist for gears and loaded parts. The right pick depends on what the part must do.
How they compare
The table maps the gap. PLA leads ease. Nylon leads wear, friction, and heat.
| Property | PLA | Nylon |
|---|---|---|
| Ease of print | Easy | Hard |
| Wear resistance | Low | High |
| Low friction | Low | High |
| Heat resistance | Low | High |
| Drying need | Rarely | Yes, a lot |
| Needs enclosure | No | Yes |
| Best for | Models, prototypes | Gears, wear, warm parts |
When to pick PLA
Pick PLA for display models, miniatures, and prototypes. It prints at 200 to 220 °C with no enclosure, per the Prusament PLA datasheet. It is the easiest filament to print.
When to pick nylon
Pick nylon for gears, sliders, and parts that face friction, load, or warmth. The Polymaker PolyMide CoPA datasheet rates its heat resistance to 180 °C. The cost is printing difficulty: nylon is highly hygroscopic and abrades brass nozzles.
