At present, 3D printing is a common processing method in the prototype industry.It can break through the shape limit, so it is very popular with customers. When making 3d printing prototype, many customers pay close attention to its price, So, how is the price of 3d printing prototype calculated?

   The prototype needs to be polished before spray paint.Take into account the smoothness of the prototype when polishing, the corner clearing whether in place. The marks of adhesion must not be visibly exposed. It can be seen that after 3D printing, the labor cost of post-processing is relatively high. In some cases, the model itself takes up a lot of area in the 3D printer, so a 3D printer cannot produce so many models at the same time. Generally in prototype industry, Due to the special situation of prototype, sometimes the quotation is not based on the number of grams. Such as hollow-carved prototype, volume prototype, full- transparent prototype and so on.

 1.Hollow-carved prototype: Support should be added to the hollowed-carved area when printing, so that the model will not be deformed, At the same time, the volume of the hollow parts is relatively large, which occupies a large area of the printer when printing; The support inside needs to be removed manually, which requires labor cost after the hollow part is printed out.

 2.Volume prototype:3D printers are fixed-size, A typical 3D printer will print many models at the same time, However, due to the large volume of the parts, it is impossible to put them into other models for printing ,At the same printing time, the printing model is less, the printing cost is high.

 3.full- transparent prototype: All transparent parts need to be polished in the later stage, and the transparency effect will be better after polishing.However, due to the complex structure of the model, it is difficult to polish it, which requires more time and increases labor costs.
