RenAM 500 Flex

The RenAM 500 Flex is an SLM 3D printer from Renishaw with a 250 x 250 x 350 mm build volume.

Specifications

RenAM 500 Flex: Technical Profile

Technology and Laser System

The RenAM 500 Flex is a single-laser (500 W) SLM/LPBF system using an ytterbium fiber laser at ~1,070 nm. The laser covers the full 250 × 250 mm powder bed: the same optical architecture as the production 500S and 500Q. Layer thickness is selectable from 20 to 100 µm.

Vacuum Atmosphere Protection

Like all RenAM 500-series machines, the Flex features the patented vacuum preparation cycle, ensuring low oxygen content in the build chamber: critical for reactive metals such as titanium and aluminium.

Simplified Powder Handling (the Flex's key differentiator).

Calibration

RenAM 500 Flex Calibration

• Material changeover and full cleaning: empty and mechanically clean all powder-contact surfaces (hopper, recoater, chamber). Expected result: no visible residue. Tip: document every changeover in the material log for traceability in ISO/AS certification contexts.
• Vacuum preparation: run the vacuum cycle and wait for O₂ stabilisation. Expected result: O₂ reading in the green zone.

Common defects

Common Challenges on the RenAM 500 Flex (R&D context)

Unoptimised parameters for a new powder

Porosity is the most common initial issue when working with a new or non-standard material: volumetric energy density (VED) must be determined systematically via Design of Experiments (DoE). Analyse coupons using the Archimedes method or CT before any production build.

Cracking in new alloys

Unknown thermal properties of research powders can cause unexpected cracking.

What it is used for

RenAM 500 Flex Use Cases

Best-fit applications:

• New metal powder qualification: rapid material changeover without cross-contamination, and direct parameter transfer to the production 500S/500Q machines.
• University and R&D laboratories: access to a full SLM platform without mandatory production automation.
