Venturi Nozzle

Venturi Nozzle

A Venturi Burner is a great example of a product that can be enhanced by using ceramic 3D printing. Read on to read about a company using this technology to produce such a product. Ceramic 3D printing a Venturi burners, and welding nozzles, blow torch nozzles and heat gun nozzle are all perfect example of a part which requires extreme temperature resistance and customisation. Indeed, the shape of these products will determine their performance.

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.

Welding nozzles, also known as blow torch nozzles, are one of the most important components of welding torches and heat guns. They are used to direct and shape the welding flame or heat gun air flow to ensure that welding or heating is done safely and efficiently.

Welding nozzles come in many shapes and sizes, which are determined based on the welding application and welding equipment used. Nozzles can be made of different materials including ceramic, brass, copper, steel and stainless steel, each with its own set of benefits.

Brass welding nozzles are corrosion resistant and preferred for welding mild steel or aluminum in tight spaces where heat is an issue. Copper welding nozzles are preferred for welding stainless steel and aluminum due to their heat conductivity. Steel welding nozzles are highly durable, which is why they are commonly used in welding applications that require frequent use.

Ceramic Nozzles

Lastly, ceramic welding nozzles are corrosion-resistant and long lasting, making them perfect for welding jobsites with harsh conditions. It is important to select the correct welding nozzle for the welding application to ensure that welding or heating jobs are done safely and efficiently.

For professional welding applications, welding nozzles should be inspected regularly for any signs of wear and tear. It is also important to keep welding nozzles clean of dirt and debris in order to maintain optimal performance. With proper use and care, welding nozzles can be used safely and last for a long time.

In summary, welding nozzles, also known as blow torch nozzles, are essential components of welding torches and heat guns that direct and shape the welding flame or heat gun air flow. They come in different shapes and sizes made of ceramic, brass, copper, steel and stainless steel. It is important to select the correct welding nozzle (material and shape) for the welding application and inspect them regularly for wear and tear. With proper use and care, welding nozzles can last for a long time.

Ceramic or Metal

Being more complicated to produce by regular processes than steel, alumina is not often used for this application even though it is the most suitable material. 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 and as a result partner with 3D Ceram and Nanoe.


For a Venturi burner a material that resists heat and flame is critical. Ceramic 3D printing uses the same materials used in conventional process. So you will see it is possible to create parts in alumina, zirconia, silicon nitride which have the following properties;

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

Venturi burners are just one example of how ceramic 3d printing can be a fabulously helpful technology. Additionally, typical applications include, aerospace, aviation, investment casting, electronic, optical, medical and luxury markets. Secondly and most controversially, ceramic materials should replace many parts made of metal. Certainly, we believe is is likely these applications would benefit from the material properties of technical ceramics. In short, if you would like to discuss a project where the material properties of ceramic could help please get in touch.

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?
