The essential principle of FDM rapid prototyping was described. An algorithm of FDM automatic support generation based on linescan was put forward. Union and minus Boolean algorithm of linescan were carried out. Roads based on character-selected method were implemented and optimized at the same time. And data obtained were stored in the file which was in a ZIF format defined by the author. It was proved that velocity of generating support was very fast and nowhere was missed.
