& ltol & gt& lt If the quantity of Li> is large, you need to open the mold, and the cost is low.
& lt/ Li>& lt Li> If your quantity is not very large, and the requirements are not particularly high, you can do 3D printing, that is, laser forming, but you can't do structural parts because its mechanical properties are not high.
& lt/ Li>& lt Li> If structural performance is required to be good, it is best to obtain it by machining, but the surface is not necessarily good. Follow-up painting can be done if the appearance is required.
& lt/ Li>& lt/ol & gt;; There are two kinds of equipment, laser forming, one is SLA and the other is SLS. If you choose mechanical processing, you need that kind of high-speed engraving machine and then polish it by hand. Thirdly, the most popular method at present is to print a plastic model with a 3D printer. I hope you will be satisfied with the above suggestions.
