Serial production of titanium suppressors at Norway’s Tronrud Engineering

July 3, 2015

Tronrud Engineering, in Eggemoen, was the first company in Norway to start commercial production in metal Additive Manufacturing. Now, with five years of experience in the field, the company has developed a new titanium firearm suppressor that it hopes will lead to rapid growth. Joppe N Christensen, of Norway’s Maskinregisteret, talked to Tronrud and reports on the state of production

The new titanium suppressor is already on sale in the hunting and sports market, having been tested by several agencies in the hunting, sport shooting and defence sectors. When the military model is approved the company is looking expand its production capacity.

Gunsmith Didrik Sorlie at Tronrud Engineering is in charge of the 3D-printer and worked on the development of the new suppressor. “Just minor technical adjustments remain before the military model is approved, and then we believe the market will be open for us,” stated Sorlie. “To start with, we do not have the capacity to meet the market demands with our present 3D-Printer, so we will have to invest in new technology in order to be able to deliver to the market.”  

The company’s current machine is running at capacity, producing over 1000 suppressors units per year. “If we get orders from the Norwegian military, or other defence customers, we will immediately need to invest in new 3D–technology that is significantly faster, and able to produce more and bigger parts than what we are presently able to do,” added Sorlie.

Sorlie demonstrated the suppressor and explained how he developed it. “Here you can see how I have built up the geometry of the suppressor to get the best strength while using the least possible amount of material. The suppressor is therefore very light without losing robustness.”

If the company succeeds with this suppressor on the global market it will have to establish a separate building with many more machines in order to handle the demand.
