Alumina nozzles with a bespoke design

Alumina nozzles with a bespoke design

An alumina nozzle offers superior performance to traditional metal ones. They can withstand very high temperatures making them ideal for applications such as thermal spray coating and welding applications. This material also has excellent corrosion resistance compared to other materials, further increasing the life span of your nozzles.

Furthermore a 3D printed nozzle using this material provides superior wear resistance compared to other materials and the opportunity to optimise the design to ensure they provide a better quality product. This results in higher accuracy and better distribution performance than other types of nozzles. Alumina nozzles also have a greater flow capacity due to their larger bore size, allowing them to handle more material at one time.

Overall, alumina nozzles are a great choice for any high-temperature or corrosive coating application where superior wear resistance and precision is required. Their durability makes them an ideal option for those looking for a longer lasting nozzle solution with excellent performance.

Material Properties

Ceramic materials have fantastic material properties for certain parts like bearings, dental implants, space components that require;

  • Good mechanical strength
  • High hardness
  • Resistance to thermal shock
  • Very resistance to wear
  • Good electrical insulation
  • Resistant to corrosion; liquids, gas and abrasion
  • Biocompatible

A real case study

A great example of a project that used ceramic 3D printing is that of a company producing Venturi burners. 3D printing ceramics for a Venturi burner is the perfect example of a part which requires extreme temperature resistance and customisation. Indeed, the shape of the venturi burner will determine the performance in the oven.

Therefore, the cone angle of the venturi burner determines the size of the flame and thus the temperature and the oven atmosphere. A broad cone triggers an oxidizing flame, whereas a narrow cone produces a reducing flame. Indeed, for portable heating equipment a venturi burner is an intrinsic component. The ability to change the flames characteristic by customising the design with ceramic 3D printing is a real competitive advantage.

Ceramic or Metal

Ceramic is more complicated to produce using traditional processes than steel. Now ceramic is a great material that can be easily used. Indeed, this ceramic can withstand temperatures up to 1500°C. Moreover, it’s wear and corrosion resistance is higher than that of metal, prolonging the useful life of the part. Importantly, the internal channels of a venturi burner are quite complex to produce using conventional ceramic manufacturing processes.

Thus, making a custom designed venturi burner in ceramic impossible without ceramic 3D printing. Alumina made parts are not more complicated than other materials to produce. 3D printing makes it possible to print internal channels, hollowed out parts as well as overhangs. Moreover, by internalising the process, producing a part requires less than a week offering great flexibility to designers.

3D Matters have searched the market for the best fully functional and proven capable technologies. It is for this reason that we are proud to work with the leading manufacturers of Additive Manufacturing equipment.

In conclusion, we specialise in the design, printing and post processing of hard-wearing materials including ceramic and metals. Could the materials properties of ceramic be an advantage to your next project?
