To put it simply, disassembly is a whole thing that needs to be disassembled into several parts and then assembled into a whole. In our prototype industry, we often hear the word disassembly because some prototypes may not be processed as a whole and need to be It can only be made by disassembling parts, so let me tell you about the situations in which 3D printing prototypes need to be disassembled and printed:
1. The prototype is too large and cannot be 3D printed.
3D printing equipment has a printing size that it can withstand. Due to its large size, the 3D printing equipment cannot print such a large prototype at one time, so it needs to be disassembled and printed separately. Whether it is 3D printing or CNC processing, there are size restrictions during processing. This is limited by the size of the machine. It is impossible for the machine to be only 1 meter, but it has to process a 2-meter prototype model. This is impossible to process.
2. The special structure cannot be processed, or the processing does not meet the requirements.
For example, when 3D printing transparent photosensitive resin, the transparent photosensitive resin needs to be polished. If some parts cannot be polished, the transparency will be affected. At this time, the parts can be disassembled for printing, polished after disassembly, and then glued together. If you choose shadowless adhesive, the transparency of the sticky parts is quite good. There are also parts that cannot be processed by CNC. Some small parts cannot be processed by CNC tools and need to be disassembled and processed.
3. Disassembly and processing may be cheaper
In 3D printing, it is rarely cheaper to disassemble and print parts within the printable range because 3D printing is additive manufacturing. In addition to the necessary support materials, the rest is the material used to print the model, and 3D printing does not require There are cases where the processing of models with complex structures is more expensive.
For example, if a CNC prototype with a height of 650mm, a length of 600mm, and a side width of 300mm is processed as a whole, it needs to be made of ABS material with a height of 650mm, a length of 600mm, and a width of 300mm. But in fact, this prototype does not require so much material. The materials required to process this prototype in one piece may be less than one-fifth of the overall processing, which is a huge waste of material. Because this prototype needs to be processed from top to bottom, left and right, CNC processing will take longer and be more complicated. Therefore, if the overall processing is for this prototype, the price will be much more expensive than disassembly and processing.
