Most 3D printed products are made in one of three plastics. The right choice depends on where the part will live and what it has to do.
| PLA | PETG | TPU | |
|---|---|---|---|
| Best for | Gifts, decor, models, prototypes | Functional parts, brackets, outdoor use | Grips, gaskets, bumpers, phone cases |
| Feel | Rigid, crisp detail | Tough, slightly flexible | Rubber-like and bendable |
| Heat resistance | Softens around 55–60 °C | Holds up to about 70–80 °C | Holds up to about 80 °C |
| Outdoor use | Not recommended in direct sun | Good | Good |
| Surface finish | Best, widest colour range | Glossy, slightly less sharp | Matte, soft |
| Relative price | ₹3 per gram | ₹3.50 per gram | ₹5 per gram |
PLA
PLA is the default for a reason: it prints with sharp detail, comes in the most colours and is rigid enough for almost anything that sits on a desk or a shelf. Its weakness is heat. A PLA part left in a parked car or in strong afternoon sun can warp, so it is the wrong choice for dashboards, balconies and anything near a stove.
Silk PLA
Silk PLA is PLA with a glossy, metallic-looking surface that hides layer lines. It is ideal for showpieces, trophies and decorative figures. It is a little less strong than standard PLA, so it is not meant for load-bearing parts.
PETG
PETG is tougher than PLA and handles heat and sunlight far better. It bends slightly before it breaks, which makes it a good choice for clips, hooks, brackets, replacement parts and anything used outdoors.
TPU
TPU is flexible and rubber-like. Use it when the part has to bend, grip or absorb impact: feet, gaskets, cable protectors, bumpers and soft cases. It prints slowly, so it costs more.
