About Zenith Tecnica

Zenith Tecnica is an additive manufacturer specialising in titanium parts. The company uses Electron Beam Melting (EBM) to Additively Manufacture (AM) parts direct from 3-D CAD files.

Based in Auckland, New Zealand, the company employs four mechanical/metallurgical engineers, and also post graduate students who undertake supervised research into mechanical and metallurgical aspects of EBM/AM.

Mechanical Design To Electron Beam Melting

Why Electron Beam Melting (EBM)?

  • Minimum Order Quantity (MOQ) = 1
  • No Special Tooling – Jigs, fixtures, molds dies and cores eliminated
  • Frees up working capital
  • Faster prototype cycle time
  • Lead times reduced
  • Near-Net Shapes (NNS) are achievable
  • Complexity is an advantage - increasing the part complexity will typically decrease the production cost with Additive Manufacturing (AM)

  • Raw Material yield in excess of 95% is easily achieved
  • No residual stresses - no distortion
  • Material only where it is needed - Topological Optimisation can be readily applied to AM parts
  • Reduced Parts Count – A key benefit of AM is the reduction in total parts count
  • Reduced assembly time and piece part inventory

  • Superior Material Properties UTS, Yield, Ductility, Fracture Toughness, LCF/HCF performance
  • High Vacuum Environment = Very low levels of chemical impurities and a highly homogenous material
  • Superior Mechanical Properties - better than cast-, and similar to wrought-titanium products
  • Lower Part Scrap Rates
  • Reduced Finish Machining - Design elements like threads, splines, or gear mesh fit class can be directly tailored during EBM manufacture.

  • Low Process Variability - highly repeatable process equates to highly repeatable parts
  • Less Material Input – the weight of material used per finished part is considerably reduced
  • Buy-To-Fly ratio is very low
  • Superior strength, excellent corrosion resistance and lower density than 316 Stainless Steel
  • Cost competitive with machined 316 Stainless Steel

Zenith Tecnica has committed itself to Electron Beam Melting (EBM) technology.

With Additive Manufacturing (AM), parts are built by successively melting thin layers of metal powder together. Material is added instead of removed, as is the case in traditional “subtractive” machining. AM enables the manufacture of complex parts that cannot be made by any other manufacturing process – this immediately creates design freedom and cost-efficiency benefits.

The EBM build speed is considerably faster compared to other metal powder AM technologies. EBM/AM is an energy efficient process that utilises the raw materials in an economical manner – inducing minimal waste products and environmental emissions – this equates to a very environmentally friendly manufacturing process.

On top of these obvious benefits, Zenith Tecnica has recently installed PV solar panels as the first step in its strategy to become carbon neutral and making the planet just that little bit greener.
