Hello, I'm Xiaobian. The user or design verification of 3D print hand board model function verification always satisfies the hash, so it's hard to avoid scraping his works carelessly. At the same time, in the process of transportation, it's hard to avoid hashing, carelessly rotting, losing printing and unwilling to give up. This is 3D print hand board model repair. Here is a practical introduction.

　　1. 用502膠水粘接。(502膠水不宜過量，會影響粘合效果，注意使用502膠水)除502膠水外，還介紹了幾種其他不同種類的膠水可以使用。

　　1. Use 502 glue for bonding. (502 glue should not be excessive, which will affect the bonding effect. Pay attention to the safe use of 502 glue). In addition to 502 glue, several other different kinds of glue can be used.

　　2. 粘貼后仍然會有一些小的間隙

　　2. There will still be some small gaps after pasting

　　3.還有一些缺失的部分，是缺口。

　　3. There are still some missing parts, which are gaps.

　　4. 先打磨縫隙，試著處理痕跡。

　　4. First polish the gap and try to deal with the traces.

　　5. 使用3d打印筆，使用ABS 3d打印材料進行修復(ABS比PLA打磨的更好)，其他材料可以進行修復。

　　5. Use 3D printing pen, use ABS 3D printing material for repair (ABS is better than PLA grinding), and other materials can be repaired.

　　6. 使用3D打印筆來填補空白。這是PLA 3D打印材料。其他材料，如SLA光敏樹脂，不能使用3D打印筆。

　　6. Use a 3D pen to fill in the blanks. This is PLA 3D printing material. Other materials, such as SLA photosensitive resin, cannot use 3D printing pen.

　　7. 波蘭。砂紙可用來拋光。砂紙厚度可根據模型的具體要求進行選擇。

　　7. Poland. Sandpaper can be used for polishing. The thickness of sandpaper can be selected according to the specific requirements of the model.

　　重復3次，以填補和拋光的差距和差距，以確保順利連接的差距和表面

　　Repeat 3 times to fill and polish gaps and gaps to ensure smooth connection of gaps and surfaces

　　8 .修的差不多，因為這是測試用的，所以隨機修，修的效果一般，比較仔細可以修的痕跡不大。

　　8. It's almost repaired, because it's for testing, so the effect of random repair is general, and the trace that can be repaired carefully is not big.

　　9. 經過以上步驟，3D打印的手板模型的修復工作就完成了，其實并不難，用更多的人手就可以很好的修復。

　　9. After the above steps, the repair of 3D printed handboard model is completed. In fact, it is not difficult. It can be well repaired with more hands.
