3D-printed ceramics will provide a significant increase in demand for additive manufacturing equipment and ceramic materials. This trend is increasingly important in the field of engineering ceramics, as well as advanced ceramic materials.
For ceramic part production, there are higher demands for process integration and ceramic 3D printing technology. It can be more difficult than usual to produce high-quality ceramic parts.
Here are five major reasons to use 3D printing technology for the manufacturing of ceramic parts.
You can create a very lightweight structure.
A function set is a collection of one or more functions that replace the existing structure. This saves time, money and enhances product performance.
Produce personalized parts, including dentures and implants for orthopedics. ;
This opens up new opportunities in logistics, spare parts supply and production on-demand.
Avoid expensive moulds by creating small-scale ceramic components.

Technology that is suitable for 3D printing in ceramic additive manufacture falls into one of two groups. Two types of technologies are available: one is that of simultaneous material shaping and densification. This technology can be used to make ceramic green embryos. However, heat treatment is required for the final product.
First, additive manufacturing processes use a higher temperature gradient. This causes higher thermal stress which can cause damage to the ceramic arts. Due to the inclusion of multiple 3D printing techniques, the complexity of technology application and quality management in the ceramic industry increases.
The issues that can arise from heat treating 3D printed ceramic components are in principle similar to problems encountered with conventional production techniques. Optimizing heat treatment may be harder. The characteristics of additive manufacturing technology mean that cracking or delamination is possible during degreasing. This can be due to high levels of the binder as well as low interlayer adhesion. 3D printing involves more intricate sintering than in conventional moulding. This may result in higher shrinkage and warpage. The deformation can be more hazardous than anisotropic shrinkage.
3D printing technology is known for its ability to make complex structures. It is important to understand how to solve the issues of heating ceramic parts 3D printed from ceramics, in order for ceramic producers to benefit from 3D printing technology.
University of Maryland scientists have developed an innovative method of fabricating ceramic materials in solid-state cells and fuel cell systems.
It is widely used for batteries, electronic devices and in extreme environments. Ceramic sintering (parts of the traditional sintering procedure used to produce ceramic objects), can often take many hours. Maryland scientists developed an ultra fast high-temperature (UHS) sintering technique to help overcome this difficulty.

Reports indicate that the older rapid sintering systems have some limitations. They are susceptible to low temperatures, long energy usage, as well as costly repairs.
Maryland’s team has developed a high-temperature sintering technique that provides uniform temperature distribution, heating and cooling at very high rates. The sintering temperature can reach 3000 Celsius. Together, these two processes require less than 10 seconds. That’s more than 1,000 times faster compared to traditional furnace interfacing methods.
This invention connects a solidified ceramic precursor powder green body to two carbon bars. Through radiation and conduction it heats quickly the particles, which causes the powder to rapidly solidify. Any ceramic material can easily be sintered, as long the temperature is not too high.
Researchers said this means that ultrafast high temperature sintering has two meanings.
