LIGHT CURING SYSTEM AND METHOD

摘要

The invention provides a light curing method, including: providing a light curing apparatus having at least one light source, at least one fan and a curing volume. A first polymerizable shaped material is positioned within the curing volume. The light source and the fan are controlled to heat the first polymerizable shaped material to temperatures within a first temperature range. The light source and the fan are controlled to maintain the first polymerizable shaped material at temperatures within the first temperature range for at least 1 minute. A second polymerizable shaped material is positioned within the curing volume. The light source and the fan are controlled to heat the second polymerizuable shaped material to temperatures eithin a second temperature range. The light source and the fan are controlled to maintain the second polymerizable shaped material at temperatures within the second temperature range for at least 1 minute. The first temperature range has afirst midpoint and the second temperature range has a second midpoint. The first midpoint is at least 15 DEG C from the second midpoint.
