Volumic Stream20Pro MK2

The Volumic Stream20Pro MK2 is an FDM 3D printer from Volumic with a 200 x 200 x 240 mm build volume.

Specifications

The Volumic Stream 20 Pro MK2 is a professional-grade FDM (Fused Deposition Modeling) 3D printer developed by the French manufacturer Volumic (based in Nice). The Pro designation indicates that the machine is optimized for printing high-temperature engineering polymers and abrasive composite materials. It combines the compact desktop footprint of the Stream 20 series with the capabilities of larger industrial systems, targeting engineering offices, automotive labs, and prototyping workshops.

Calibration

Achieving a 15-micron precision when printing technical materials on the Volumic Stream 20 Pro MK2 requires a calibration process.

• High-Temperature Bed Calibration

Thermal expansion of the aluminum bed plate at 150 °C will alter its physical geometry. Calibration must be performed at printing temperature.

• Expected result: A uniform 0.1 mm nozzle-to-bed clearance across the entire build plate at operating temperature.

Common defects

• Hardware defects and mechanical weaknesses
• Extruder Gear Wear from Composites: Carbon and glass fibers act as an abrasive file on the extruder drive gears. Standard brass or nickel-plated gears will wear down over time, leading to filament slippage. Solution: Replace the drive gears with hardened steel versions when printing composites.
• Bed Heater Cable Fatigue: At 150 °C, the cables under the bed are subjected to thermal stress and bending along the Y-axis.

What it is used for

Best use-cases

• Composite Functional Parts (PA-CF/PET-GF): Ideal for printing gears, mounting brackets, and structural components.
• Aerospace and Automotive Prototyping: Printing functional components resistant to chemicals and high temperatures (PEEK, PC).
• Medical Mockups and Templates: Printing with biocompatible materials that can withstand thermal sterilization.
