Metal 3D printers in 2022: a comprehensive guide (Part 2)

3D Systems, a historical actor on many 3D printing fronts, presents the DMP FLEX 100 as a fast, precise, and affordable metal 3D printer. It offers impressive part repeatability and surface finishes, of around 20 μm and 5 Ra μm respectively. DMP stands for Direct Metal Printing.

The printer comes with 3D Systems’ software 3DXpert All-in-One Software Solution for Metal Additive manufacturing. Their LaserForm metal 3D powders are certified.

This compact metal 3D printer is destined for the production of small parts in small quantities. Its material portfolio is especially interesting for medical use cases, namely dental crowns and bridges. EOS certified metal powders include Cobalt-Chrome, Stainless Steel, and Titanium.

The EOS M100’s laser spot is precise enough to provide a great level of detail, backed by 200 W of powder.

Originally a Swedish company, Arcam was acquired by GE Additive a few years ago. The Arcam EBM Spectra L is up to 20% faster than its predecessors and is able to reduce part costs by around 10%.

This metal 3D printer is dedicated to Titanium 3D printing, but Copper is in the pipeline as well. Its laser beam power is equal to 4.5 kW, partly explaining the printer’s high melting capacity and productivity. Common applications for this printer include orthopedic implants and parts for the aerospace industry.

Concept Laser is the company behind GE Additive’s M2 Series 5. It offers an easy, optimized workflow, with a separate processing chamber and handling area that is integrated into the system. This closed-loop material system ensures a safe environment that is free of powder for the operator.

The M2 metal additive manufacturing solution is compatible with a range of metals, from Stainless Steels to Aluminum, Nickel, Titanium, and Cobalt-Chrome.

The RenAM 500E is Renishaw’s entry-level metal additive manufacturing solution. It offers a relatively large build volume and powder can be handled via a dedicated glove box to avoid powder from getting free.

This system is also equipped with an oxygen sensor and a proprietary emission-filtering system branded SafeChange™.

The TruPrint 1000 is TRUMPF’s most compact metal 3D printing system, with a 100mm-tall cylindrical build volume. It is suitable for the production of small parts and prototypes, and even small production series when equipped with the multilaser option that increases the printer’s speed.

This metal 3D printer can be operated remotely via a tablet application, which also gives access to its onboard camera stream.

The Velo3D Sapphire is a high-volume metal 3D printer from the US designed for production series. This metal 3D printer features Velo3D’s Intelligent Fusion technology to allow for complex geometries and 0° overhangs.

The system is also equipped with a range of metrology sensors that measure each and every layer that is 3D printed.

The XM200C is Xact Metal’s entry-level metal 3D printing solution. It is suitable for both research purposes and small production series. The XM200C benefits from a proprietary Xact Core gantry system for precise movements with a fusing speed of up to 500 mm/s.

Xact Metal offers their own materials, branded Xact Powder, including various Stainless Steels, Super Alloys, Tooling Steels, Aluminum, Titanium, Bronze, and Copper. Advanced users are able to use their own metal powders if needed.
