Three-dimensional printing process printing (3DP-Three-Dimensional Printing) with an adhesive through a nozzle (e.g., silica gel) the part of the cross-sectional “printing” in the above material powder. The lower part with an adhesive strength of the adhesive, must workup. Specific process is as follows: After the completion of the adhesion layer, forming a drop from the cylinder (equivalent layer thickness: 0.013 ~ 0.1mm), the height of a powder supply cylinder rises, the introduction of a number of powder, and powder spreading roller to push the forming cylinder, paving and compaction. Nozzle under computer control, the construction of a press section of data forming binder is selectively ejected level construction. Excess powder collector means for collecting powder when the powder-dusting rollers. Again and again the feed powder, powder spreading jet and a binder, the final completion of a three-dimensional bonding powder. After local injection is not a dry powder binder, play a supportive role in the forming process, and shaped ends, relatively easy to remove.
