3D Printed Polishing Burner - 3d printing technology for the fabrication of complex geometries in hollow glass manufacturing

3D Printed Polishing burner aims at improving the efficiency of the polishing step of glass articles during their manufacturing process. Once a glass article is formed by pressing molten glass in a mould, some defaults remain on the surface and need to be polished with a flame from specific burners. The objective of glass reheating and edge-melting is to remove the defaults and to give the glass articles (tableware, perfume containers, crystal glasses,...) a smooth and shiny appearance. Where classical burners waste most of their flame in the atmosphere, the innovation made with the 3D Printed Polishing burners enables to improve the flame efficiency. Allowing for a reduction in natural gas and oxygen consumption, the 3D Printed Polishing Burners decrease the level of CO2 emissions related with glass polishing.

Key features

  • The 3D printing technology decreases by 50% the weight of burners with equivalent dimensions and flame output (same number of rows for equivalent length)
  • The higher grade of material used for the 3D printing conception improves the lifetime value of the burner up to 30% and makes them easier to clean up
  • For oxy-fuel burner, the higher efficiency of heat flux transfer to the article during a very short time of exposure leads to a reduction in natural gas and oxygen consumptions by 10%
  • Reducing gas consumption generates a 13% reduction of CO2 emissions
  • Improved burner's lifetime reduces the frequency of material renewal (less consumption)


  • 3D burners are proposed at a lower price (from 10% to 20% depending on the number of units)
  • The money saved on gas consumption leads to shortened payback time of less than 1 year
