RenAM 500

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

Specifications

The Renishaw RenAM 500 is a high-end industrial metal additive manufacturing system utilizing Laser Powder Bed Fusion (LPBF / DMLS) technology. Engineered by the British metrology expert Renishaw, the system is designed for volume production and R&D of critical components in sectors such as aerospace, automotive, space, and medical implants. At this industrial tier, the baseline parameters function under a different engineering paradigm compared to standard FDM desktop systems.

• Hotend / Nozzles: The system does not utilize a heating block, nozzle, or physical extrusion drive. The thermal energy is delivered via high-power laser optics.

Calibration

Calibration of an industrial LPBF system requires metrological precision. Standard FDM tests are replaced with certified procedures that ensure repeatability for aerospace and medical components.

• RESOLUTE™ Z-Axis Encoder Calibration: Calibrate the Z-axis using reference gauge blocks and a dial indicator to verify displacement accuracy.
• Expected result: Z-axis displacement errors are held below 0.1 microns over a single step, ensuring accurate layer thickness.

Common defects

The Renishaw RenAM 500 operates under high thermal and chemical stresses. Component wear or calibration errors can result in expensive build failures.

• Hardware defects and mechanical weaknesses
• Protection Window Contamination: During the melting process, metal vapor and soot are generated. If the gas knife flow is not uniform, these particles deposit on the optical protection window.

What it is used for

Excellent Use-Cases:

• Aerospace & Defense Components: Manufacturing fuel nozzles, turbomachinery blades, and structural brackets in Inconel 718 or Titanium Ti6Al4V.
• Medical & Dental Implants: Producing custom cranial plates, orthopedic implants with porous lattice structures, and dental substructures in Cobalt-Chrome or Titanium.
