3D Systems sPro 230 HS

The 3D Systems sPro 230 HS is an SLS 3D printer from 3D Systems with a 550 x 550 x 750 mm build volume.

Specifications

3D Systems sPro 230 HS: Technical Specifications

Laser System

Two CO₂ lasers at 70 W each (140 W total) operating at 10.6 µm wavelength. The dual-laser configuration splits the build volume into two sintering regions, synchronized for a smooth overlap zone.

Build Volume

550 × 550 × 750 mm: the largest in the sPro series, representing approximately 226 liters of powder bed volume. Enables sintering of full-scale automotive and aerospace components.

Optics and Scanning

Two independent galvanometer scanning systems with F-theta lenses, synchronized in the overlap zone via 3D Sprint.

Enclosure and Environment.

Calibration

Calibration Protocol: sPro 230 HS

• Coordinated laser calibration: Calibrate both lasers sequentially in 3D Sprint. Sinter test coupons in the overlap zone and inspect for visible boundaries or density differences.
• Thermal homogenization: Heat the chamber and wait a minimum of 60–90 minutes for full stabilization of the 550×550 mm build area. Thermal gradients are the primary risk at this scale.
• 9-point leveling: Measure the work surface in a 3×3 grid.

Common defects

Common Defects and Solutions, sPro 230 HS

Overlap zone boundary, Visible line or density change at the boundary between the two laser regions. Cause: unsynchronized laser parameters. Fix: coordinated laser calibration; test coupons in the overlap zone.

Warping of large parts: Deformation during cooling. Cause: thermal gradients across the large build area. Fix: improved thermal homogenization; slower cooling cycle; vertical orientation of flat parts.

What it is used for

Applications, sPro 230 HS
