Final answer:
Stereolithography (SLA) is more accurate than Direct Light Processing (DLP) due to its use of a laser, left-to-right configuration, and the resin it uses.
Step-by-step explanation:
Stereolithography (SLA) is more accurate than Direct Light Processing (DLP) in several ways. Firstly, SLA uses a laser to selectively cure liquid resin layer by layer, resulting in precise and detailed prints. In contrast, DLP uses a digital light projector to cure an entire layer at once, which may result in less accurate prints.
Secondly, SLA printers typically have a left-to-right configuration, moving the laser and build platform from left to right. This configuration allows for smoother and more consistent prints due to the lower chance of optical distortion compared to DLP printers.
Lastly, the resin used in SLA printers often has different properties and characteristics compared to what DLP printers use. This can lead to variations in the accuracy and outcomes of the printed objects.
