Montana Rifle’s Transition to Metal 3D Printing with 3DEO


High costs led the Montana Rifle Company to look for a new manufacturing option for their small parts. Low or no startup cost was necessary because they’d be transitioning to a different manufacturing process.  Also, the company needed the parts to be scalable, since the demand was higher during certain months.


Instead of using CNC machining with multiple setups, 3DEO used their proprietary 3D printers to manufacture each part in one step. The solution provided by 3DEO offered superior part performance with premium steel (17-4 PH), while providing the ability to seamlessly scale quantities into larger or lower volumes.

Why Montana Rifle Chose 3DEO Over CNC Machining

No Startup Costs

Offered production scalability, with no tooling or start-up costs to switch to metal 3D printing.

Short Lead Times

Introduced designs rapidly for fast market entry, with the ability to make design improvements and changes without paying the price of tooling costs.

Flexible Manufacturing

Scalable quantities up/down to match demand; Purchase orders that started based on inventory consumption rate.

Design Excellence

3DEO’s parts exceeded MPIF standard 35 while enabling scalable production for Montana Rifle Co.’s extensive product line.
