What is silica gel 3 d printing, silica gel can also do 3 d printing materials, silica gel at home and abroad the status quo of 3 d printing?
silica gel is a highly active porous materials, has a stable chemical property, high adsorption properties, good thermal stability and high mechanical strength. In recent years, this kind of material is also beginning to use 3 d printing, ceramics, and graphene to wipe a spark, known as the three most market prospect of new 3 d printing materials. What is the status of the silicone 3 d printing at home and abroad?
foreign silicone market has developed rapidly in three dimensions:
in October 2014, FrippDesignResearch company announced a 3 d printer can use the silicone print - Silicone Picsima 3 d printers. Print size is 100 x 100 x 30 mm, printing layer thickness of 0. 4 mm, printing product hardness can be low to shaw 10. A, which means it can be up to the level of the super soft, and can be repeated tensile fracture.
Picsima process is a 3 d printing and light curing between powder bed between 3 d printing process. Using catalyst sintering or curing special silicone oil filling 'material pool. With a 3 d printer needle extrusion head quantitative catalyst coating to the surface of a silicon oil layer. Since the catalyst can quickly cured silicone, the print does not need to support and post-processing. In addition, in the printing process using the crosslinking agent, and print the object of all parts of the softness and subject to change depending on the crosslinking agent. Finally, the process can also be dyeing and printing, to produce color silica gel.
Picsima silicone 3 d printer has been approved by FDA for use in medical and food industry, which has been patented. The room temperature vulcanization ( RTV) Medical grade silicone material can be widely used in 3 d printing prosthesis ( Ear, nose, denture, etc. ) , medical equipment, consumer electronics and industrial prototype, and has been approved for human body. Picsima also found that, in fact, in combination with 3 d scanning technology, doctors can use it in the huge breast implant industry.
3 d silicone printing slow development in China:
at present, the domestic production of silicone product model mainly rely on manual operation, is made of vulcanizing machine high temperature forming, skin seema minimum printable shaw 10 a hardness, the softness to many domestic manufacturers of silicone products, used by only using liquid processing, namely according to the characteristics of the silica gel, printing the finished product can be up to the level of the super soft, can be repeated tensile fracture. The 3 d printing technology manufacturers has applied for patents, and obtained the PCT patent certificate, and has set up a new company to provide customers with 3 d printing technology.
