Introduction of Ceramic 3D Printing

There are many many disadvantages on traditional ceramic manufacturing technology, such as which needs long lead time (at least 8 ~ 12 weeks); not suitable for making complex geometric configurations like hollow sphere. Some special geometric configurations, or some parts of the design often is not suitable for mechanical processing, which needs for a costly follow-up processing methods: certain pattern or model must use expensive carbide or diamond and other tools to processing before and after the ceramic sintering. So small manufacture often need expensive cost and long delivery time.

Ceramic production with the ceramic 3D printing costs  90% less time than the traditional methods, even the time of delivery may within 5 days. The new technology not only saves time, and at the same time also allows designers change their design in the ceramic production process. There are various kinds of ceramic materials can be used in the 3D printing technology, from the alumina ceramic (alumina filler) whose hardness was a little weak to very hard zirconia ceramic (zirconia silicate filler)  with wear-resistant .These ceramic can tolerate high temperature of 1500 ~ 1700 degrees, the dielectric strength of which up to 150 kv/mm. The alumina ceramic materials not only  has strong wear resistance but also corrosion resistance, and is an ideal mechanical manufacturing raw materials.

The characteristics of alumina ceramics:

High strength and high hardness
Excellent wear resistance
High resistance to corrosion
Excellent thermal stability
Excellent dielectric strength

A typical application of the alumina ceramics:

Used as a nozzle in the high friction environment (such as sandblasting)
Used for air gun protection cover in high temperature environment (such as welding equipment)
Used as a base in corrosive environment (such as car manufacturing tactile sensor installation)

Many parts can be designed for half a hollow structure with the ceramic 3D printing technology, thus the weight reduction and cost savings achieved.
