Ultra-fast high-temperature sintering method 10 seconds to quickly fire ceramics-can produce delicate 3D printed structures

Users will continue to demand ceramic additive manufacturing hardware materials in the near- and long-term due to the high value of 3D printed components. This is a more significant trend for advanced ceramic materials as well as engineering ceramics.

Production of ceramic parts requires higher costs for ceramic 3D printing technology, process integration and cost. However, conventional ceramic part manufacturing is much more difficult.

The following are the five reasons 3D printing is being used to produce ceramic parts

Construct a light structure

One part of the function sets replaces many parts in the previous structure. This reduces assembly time and improves product performance.

The On-Demand Production option opens new doors in logistic and spare part supply.

You can now create ceramic parts on a small scale by eliminating the need to make expensive moulds.

The technologies available for 3D printing ceramic additive manufacturing generally fall under two categories. There are two main types of technology available for 3D printing in ceramic additive manufacturing. One is simultaneous material molding and density, which includes powder bed melt, direction energy deposition, and material injection. The other technology is separation frame and densification. These include sheet lamination and Binder spraying as well as photopolymerization (SLA, DLP). To produce the final product, these 3D-printing technologies must heat treat the green body.

Due to the higher temperatures used in additive manufacturing, the process results in more thermal stress, and therefore, ceramic art is less popular than the other types. Because the second type includes multiple 3D printing technologies, it makes it difficult for technology to be applied and improves quality control in the area of ceramic production.

The heat treatment problems of 3D-printed ceramic parts is similar to traditional production processes. But optimizing heat treatment is often more complex. Degreasing can cause cracking or delamination due to the additive manufacturing process’s low concentration of binder. 3D printing is often more complex than traditional moulding, and can result in increased shrinkage and warpage. For 3D printing complex filigree structures, anisotropic shrinkage is often more prominent than for conventional moulding processes. This makes deformation more risky.

3D printing has the advantage of being able to create complex structures, which is an obvious benefit over other technologies. What can be done to avoid the problems associated with heat treating 3D printed ceramic components?

Researchers from the University of Maryland (UMD), have reinvented a 26,000-year old manufacturing process to create ceramic materials for solid-state fuel cells and 3D printing.

Electronic products, extreme environments and batteries all use ceramics. The traditional process of making ceramic objects requires several hours to complete. Maryland’s research team devised an ultrafast high-temperature method for sintering ceramics (called UHS) to solve this problem. It can also be used to promote new materials discovery.

According to some reports, the old rapid sintering processes have their limitations. These include low time, energy, temperature and cost.

Maryland has adopted a new method of ultra-high temperatures sintering. It provides high heat and cooling rates as well as uniform temperature distribution and can sinter at up to 3000 Celsius. The total time needed to process these procedures is under 10 seconds. This is over 1,000 times faster that traditional furnace sintering processes.

It combines a green, compacted ceramic pre-cursor powder with two carbon bars. By conduction and radiation, it rapidly heats particles and causes them to solidify. Any ceramic material is able to be sintered provided that the temperature remains high enough.

According to the researchers, this technique has two meanings.
