Can soft rubber silicone material be produced by 3D printing?

The brand with the highest market share of 3D printing soft rubber should be Israeli, but they have a common point with American equipment( Compared with the material of 3D printing resin, the maximum printing size of 3D printing soft rubber is slightly biased, small, ) if not mistaken, the US and Israel equipment currently has a maximum print size of no more than 400mm, and only black and white in color. But China’s 3D printing soft silicone equipment, its biggest highlight is that it can print full-color soft rubber in 3D.

But have to say, the accuracy of Israel’s 3D printing soft plastic equipment is higher than that of the United States and China. From the theoretical data, they can achieve 0.016mm but usually we can basically print out the accuracy of the soft silicone with 0.025mm.

The only issue of 3D printing soft rubber is that the pricing method can’t usually be calculated according to the weight or volume like 3D printing resin or nylon material. The basic pricing method of printing soft rubber require the customer to give the design to the printing manufacturer. It is calculated in the software of the printing manufacturer’s equipment, so it will affect the speed of the quotation. This is very inconvenient.

So when the 3D printing soft rubber was not born in the market in the early years, how did it be solved when it encountered the soft rubber hand model? In fact, everyone should know that it is made by means of silicone lamination(Vacuum casting). Of course, there are still many ways to solve the problem of soft plastic prototypes on the market. The difference between it and the 3D printing soft rubber is mainly in the hardness. But the developing of 3D printing technology has made leaps and bounds in their predecessors from only a couple of short years back. Please find the short video about prototypes made by 3D printing.

If the number of soft rubber is relatively large, it is highly recommended that adopt the method of vacuum casting, but the disadvantage of silicone film soft rubber is that its precision is relatively worse compared to direct 3D printing. The detailed precision depends on the structure of design and how many pieces you want to copy in every vacuum casting process.
