Since scanning has the tolerance, it is very difficult to get the same result with the original part completely. It is always necessary to get all the related parts scanned even though some of them are not needed. The reason is to ensure a good assembly.
Three ways to make the prototype
3D printing is mature technology in recent years, and the printing quality is getting better and better. Printing pricing is based on the weight, so it is economical for the lightweight parts. Most importantly, process is very fast, normally you can get it in a few hours.
CNC prototyping is much more expensive than 3D printing, and with no doubt of the better quality. Because it is machined, tolerance can be controlled into as low as ±0.05mm. Various feasible post-treatment, such as silk screen printing, oil painting, polishing etc. are all available. It is widely used if you want to show your product to your end customer before putting it into the market. It can also be used as the small volume pilot run before mass production.
The process is :
- Make a CNC or 3D printing prototype firstly and then put it into a special soft material to form a cavity.
- Split it into two parts, core and cavity, similar to the mold, right? They are indeed a simple mold!
- Pour the special prototyping raw materiel from the gate to get the part.
It is very easy, right? But this simple mold has a very short lifespan, 10 shots at most, but it is a good choice if you need 10 or dozens quantity. Be aware of another point, part quality will not be the same as the injection ones, definitely.
