Following the strategic collaboration announced in April 2026, Eplus3D, Rosswag Engineering and qualloy have reached an important new milestone with the introduction of Eplus3D select, a validated powder range developed to support reliable and cost-efficient metal additive manufacturing.
The initial portfolio includes 316L and 17-4PH, both fully tested and validated on Eplus3D systems. From 9 November 2026, the materials will be available through the qualloy online shop, with stock held locally in Germany and delivery available within two to five business days. Customers already using Eplus3D process parameters for these alloys can transition directly to the corresponding Eplus3D select materials.
From Strategic Collaboration to Validated Materials
When the three companies announced their cooperation in April, the goal was to combine Eplus3D’s industrial metal PBF technology, Rosswag Engineering’s qualification and testing expertise, and qualloy’s material and powder supply capabilities into a more integrated manufacturing ecosystem.
The collaboration focuses on joint material qualification and parameter development, creating validated material-process combinations that can help simplify adoption and support more scalable industrial additive manufacturing. The launch of Eplus3D select now represents the first tangible outcome of that approach.

A Connected Validation Process
Validation builds are produced at Eplus3D Germany using Eplus3D select powder supplied by qualloy. Tensile specimens from the builds are then tested by Rosswag Engineering, creating a connected process from material supply and printing through to mechanical validation.
For 316L validation builds produced on the EP-M300 with a 50 μm layer thickness, the measured density exceeded 99.9%. Additional validation data for 17-4PH also showed a density above 99.9%. The reported density evaluations covered wall thicknesses down to 0.5 mm and 35° overhangs.
The mechanical properties of both materials in the XY and Z build orientations are summarized below.
Material | Build orientation | mE (GPa) | Rp0.2 (MPa) | Rm (MPa) | A5 (%) |
316L | XY | 166 ± 15 | 531 ± 15 | 664 ± 15 | 41 ± 5 |
316L | Z | 149 ± 10 | 452 ± 10 | 585 ± 15 | 51 ± 5 |
17-4PH | XY | 151 ± 12 | 464 ± 10 | 957 ± 10 | 29 ± 5 |
17-4PH | Z | 168 ± 5 | 575 ± 12 | 980 ± 10 | 26 ± 5 |

This approach helps ensure that customers receive materials that have already been evaluated in combination with Eplus3D systems and established process parameters, reducing the amount of additional material qualification work required when introducing the corresponding powder.
For the partners, the development brings together machine technology, established process parameters, validated materials and local powder availability into a more connected offering. Together, Rosswag Engineering, qualloy and Eplus3D are building on the original partnership goal of creating a more integrated and validated metal additive manufacturing ecosystem.
Supporting More Practical Industrial AM
Material availability and cost remain important considerations when metal additive manufacturing moves toward larger production volumes. The Eplus3D select range is therefore designed not only around validated processing, but also around practical supply.
With powder stocked in Germany, customers can access the initial 316L and 17-4PH range with shorter delivery times and competitive pricing. Further validated powders are planned to be added progressively, expanding the range of material options available for Eplus3D users.

A sample validation build will be displayed at Formnext, giving visitors a closer look at how the Eplus3D select material validation process is carried out. Visitors can meet the teams at the Eplus3D or qualloy booths to learn more about the new powder range.
With the first validated materials now moving from qualification into commercial availability, the collaboration between Eplus3D, Rosswag Engineering and qualloy is progressing from a shared industrial vision toward a more practical material and process ecosystem for metal additive manufacturing.
