What kind of product must be disassembled before 3D printing

The first is that the prototype model is too large, exceeding the maximum print size of the 3D printer

　　 For example, when printing a car model, the 3D printer cannot print the large model at one time due to its large size. At this time, it needs to be printed separately.

Whether it is 3D printing or CNC machining, the processing size is limited, which is limited by the size of the machine tool. It is impossible for the machine to be only 1 meter, but it is impossible to process a 2-meter prototype model. The maximum size of a single 3D printing model of different 3D printing materials is also different.

Second, the special structure cannot be processed

　　 For example, a square sealed box is a structure that needs to be used for support. 3D printing can be printed and sealed, but there will be support, and customers certainly don't want to be supported. At this time, it needs to be disassembled and printed, and the support is removed. For example, the glasses in the picture below are printed separately from the frame and legs, because the interface between the frame and the legs is closed and cannot be flexibly rotated when printed together, so the hand model of the glasses cannot be used. Of course, the glass in the figure below is printed in a single piece, and by design, the final 3D printing can also make the flexible device rotate. The example here is for reference only.

For example, to print transparent photosensitive resin on 3D printing, the transparent photosensitive resin needs to be ground, and the position of the rod is still good.

There are some parts that cannot be processed by CNC machine tools. Some small parts cannot be processed with CNC knives and gongs and need to be disassembled for processing.

The third type is that disassembly processing may be cheaper

The material was wasted. Since the prototype model needs to be processed up and down, the CNC machining time will be longer and more complicated. Therefore, if the handle plate model is processed as a whole, the price will be much more expensive than the parts to be processed.

In the printable range, 3d printing is rarely cheaper than printing, because 3d printing is additional manufacturing. Except for necessary auxiliary materials, the rest are materials used to print models. 3d printing does not have complex structures and high model processing costs. Case.

After the parts are printed, the parts must be glued together. If the parts are glued together, it will leave a sticky mark, which is a spliced mark. If the 3D printed manual model is for appearance verification, it will have little effect, because the glue mark cannot be seen after the manual model is colored. If it is a function verification, it may be affected by a point, because the force will be affected some, of course, as a function test, it is necessary to see the structure, use and materials of the manual model.
