SLA vs DLP 3D Printing
Both cure resin, but SLA traces each layer with a laser point while DLP flashes a whole layer with a projector. DLP is often faster per layer; SLA can edge ahead on large-area accuracy.
| SLA | DLP | |
|---|---|---|
| Light source | Laser point traces the layer | Projector flashes the whole layer |
| Speed | Slower on dense layers | Constant per-layer time (great for batches) |
| Detail | Excellent; consistent across the plate | Excellent; pixel size sets resolution |
| Best for | Large detailed parts, accuracy | Small batches, fast repeat prints |
