Abstract：
 The present invention relates to technology and apparatus with high energy beam to sinter or melt and deposit material successively to realize laminated solid manufacture. The present invention features that the electronic beam scan controller controls the electronic beam to scan fast in pattern projection mode for heating powder homogeneously. Each scanning of the electronic beam has short time in the selected area, so that the scan initiating point has no great temperature change generated during the whole scanning course. Through one or several frames of scanning, the material in the forming area has temperature synchronously raised to reach the sintering or re-melting temperature for deposition onto the forming area before synchronous cooling. The present invention has greatly reduced heat stress and raised forming precision and quality.
