The Percentage molten layer result is generated from a Cool analysis using 3D analysis technology and shows the percentage of polymer that has not frozen at the time specified.
3D parts often have thick sections that are difficult to cool. Some sections may freeze quickly, while thicker sections take longer to freeze. This result allows you to see which sections of the part are cooling more slowly.
The percentage molten layer should be very low, indicating that the part has cooled sufficiently. If the part is ejected before it has been cooled sufficiently in the mold, the part will cool outside of the mold and will be prone to warpage.
