Types of SLA 3D Printing
There are different types of SLA 3D printing technologies, each with its unique characteristics. The following table compares these types:
| Type | Description |
|---|---|
| Top-Down SLA | The laser source is positioned above the resin vat, and the build platform moves downwards. |
| Bottom-Up SLA | The light source is below the resin vat, and the build platform moves upwards, allowing for easier resin flow. |
| DLP (Digital Light Processing) | Uses a digital projector to cure an entire layer at once, speeding up the printing process. |
| LCD (Liquid Crystal Display) | Similar to DLP but uses an LCD screen to project light patterns, suitable for lower-cost printers. |
