ProX DMP 300


Highly automated, serial 3D metal part manufacturing with tightest tolerances, unmatched resolution and surface quality.

The ProX DMP 300 is a high-performance, high-quality metal 3D printed part manufacturing system, offering reduced waste, greater speeds for production, short set up times, very dense metal parts, and the ability to produce very complex assemblies as a single part. With a build volume of 250 x 250 x 330 mm (9.84 x 9.84 x 12.99 in) it features an automated material loading and recycling system.

Integrated precision metal printing solution for guaranteed results

We offer you an integrated solution. Our revolutionary software solution for metal additive manufacturing, 3DXpert, combined with the ProX DMP 300 printer with patented technology, the extensively tested suite of materials, and finally yet importantly, the expertise of our application engineers, interlock to realize time, cost and functionality benefits for our customers.


Finest details, thinnest wall thicknesses, best surfaces

Due to 3D Systems’ patented layer applying technology, smaller particles can be used that allow to generate finest feature detail and thinnest wall thicknesses. A surface finish quality of up to 5 Ra μm (200 Ra micro inches) is achievable, requiring less post-processing. Due to the proprietary powder deposition system, the ProX DMP 300 builds down to 20° angles without supports. Less supports and improved surface quality ultimately mean less post processing and less material usage – saving time and cost.


Clean and safe for more environments

Sealed powder loading and recycling prevents material contamination and increases operator safety.
