There are many methods for making handboard models. The first one is CNC processing, silica gel molding and 3D printing. At present, more and more plastic handboards choose 3D printing. 3D printing is also a relatively new processing method. Let's introduce how to make 3D printing handboard models for us? 3D printing needs constant temperature and humidity, so the air conditioner and humidifier in the workshop are open all year round, and the temperature is controlled at 26 degrees

▲而3D打印更關鍵的便是這幾臺SLA 3D打印機了，打印機整體外形。

▲ the key to 3D printing is these SLA 3D printers, and the overall shape of the printer.

▲沿著墻角擺放的便是3D打印手板的更首要的質料——光敏樹脂。

▲ placed along the corner is the most important material of 3D printing hand board - photosensitive resin.

▲打印機內部。激光光束在液體樹脂的外表掃描零件的橫截面形狀，在紫外激光的光束照射下的樹脂固化形成掃描形狀的零件橫截層，結合在之前形成的零件橫截層上。

▲ inside the printer. The laser beam scans the cross-sectional shape of the part on the surface of the liquid resin, and the resin under the irradiation of the ultraviolet laser beam solidifies to form a scanning cross-sectional layer of the part, which is combined on the previously formed cross-sectional layer of the part.

▲打印好的產品要清洗池進行清洗然后進機器進行固化處理3D打印的優勢是速度快，就能交貨，節省了大量的時刻。另外，盡管一些精度十分高的、轉彎抹角或許鏤空的、純曲面復雜的結構，3D打印在這方面會更有優勢；3D打印是一次成型，無需組裝。

▲ the printed products should be cleaned in the cleaning tank and then solidified in the machine. The biggest advantage of 3D printing is that it can be delivered in one day, saving a lot of time. In addition, 3D printing will have more advantages in this regard, although some structures with high precision, roundabout or hollowed out, pure surface and complex structure; 3D printing is one-time molding without assembly.
