17-4 PH Stainless Steel (DM Production System)

DESKTOP METAL®

17-4 PH Stainless Steel

Acid & Corrosion Resistant Steel Alloy
for Industrial Applications

17-4 PH Stainless Steel is a martensitic precipitation-hardened steel. Thanks to the Single Pass Jetting™ technology of the Production Systems, this steel is used in various industrial applications including those with mildly corrosive environments and high-strength requirements.

Speed. Quality. Cost-per-Part.
Better than traditional manufacturing.

 

The 17-4 PH Stainless Steel alloy for 3D printing on the Production Systems™ allows companies to quickly and efficiently produce custom parts that cannot be made through conventional manufacturing. Many applications that suppose mildly corrosive environments and high-strength can take advantage of this alloy’s mechanical properties.

BMW Water Wheel_DM

BMW Water Wheel

Manufacturing - Automotive 17-4 PH

The waterwheel is an integral part of BMW’s engine cooling system.

Full Description

This integral part of BMW’s engine cooling system was originally made of several plastic parts therefore BMW redesigned it for printing on a laser-based system. It turned out that the process was too slow and expensive for mass production.

The Production system ensures higher throughput, allowing the part to be manufactured at a competitive price.

Surgical_Nozzle production system

Surgical Tool Nozzle

Healthcare 17-4 PH

Nozzle used during surgery; customized for each patient.

Full Description

To produce this surgical nozzle in the traditional way, complex machining operations with multiple fixturing setups would be needed. With Production System™, all those steps can be eliminated which means diminishing costs.

This nozzle is specifically designed for each patient with a customized internal channel. With no tooling, the ProductionSystem allowed for this part to be mass customized and manufactured.

VW_Audi_Fixture-Production System

Audi Fixture

Manufacturing - Automotive 17-4 PH

This custom manufacturing fixture was created for use on an Audi production line.

Full Description

This fixture would normally be manufactured in multiple pieces and welded together because of complex internal conformal cooling channels that span the base and the wall. It would be too expensive and time-consuming to scale if the production volume increases.

Using the Production System, the Audi fixture was printed as a single part with cooling channels intact thus reducing part cost, lead time, and manufacturing complexity.

Specs
  • Size (mm): 127 x 51 x 38
  • Cost per part ($): 19.18
  • Parts per build: 110
  • Annual throughput: 41,500

Parking_Brake_Housing_production system

Parking Shift Bracket

17-4 PH Stainless Steel

This bracket is used in the parking brake assembly of a continuously variable transmission.

Full Description

With traditional powder metallurgy techniques, this part would need a complex die and multiple operations to be produced. The Production System™ enables the redesign of this part to consolidate an assembly into a single part with no tooling, and reduced lead times and costs.

Specs
  • Size (mm): 93 x 44 x 12
  • Cost per part: $2.84
  • Parts per build: 680
  • Annual throughput: 248,980

nTopology-Gear_Production System

Ntopology Gear

Engineering Design 17-4 PH

The nTopology gear features a complex internal lattice structure only achievable via 3D printing.

Full Description

This part features a complex lattice structure used to lightweight the part while still providing strength.

With Production System™ you can manufacture complex geometries that cannot be produced any other way.

Specs
  • Size (mm): 63 x 63 x 12.5
  • Cost per part ($): 6.09
  • Parts per build: 460
  • Annual throughput: 165,980
