The (often referred to as the “128” platform variant or compact series by SLM Solutions) is a precise, industrial-grade, small-footprint metal 3D printer. It is designed primarily for rapid prototyping, low-volume components, and research-focused material development. 📋 Full Technical Specifications
The system packages high-power laser electronics into a highly compact frame. The standard specifications for this powder bed fusion system include: Build Volume: 125 x 125 x 125 mm Laser Configuration: Single 400W Fiber Laser Layer Resolution: 20 µm to 75 µm Minimum Laser Spot Size: ~70 µm
Build Chamber Atmosphere: Sealed environment under Argon or Nitrogen inert gas protection Substrate Plate Pre-heating: Up to 200°C Machine Footprint: 1400 x 900 x 2460 mm Machine Weight: Approx. 700 kg
Power Requirements: 400V, 3-phase, 32 A, ⁄60 Hz, ~3 kW consumption 🔬 Metal AM Capabilities & Features
The printer uses Selective Laser Melting (SLM), a Laser Powder Bed Fusion (LPBF) technique where a high-energy laser fully melts and solidifies fine metallic powder layer-by-layer. 1. Material Openness and Versatility
The system is built on an open-source software architecture, allowing users to modify parameters and run any reactive or non-reactive metal powder. It routinely processes: Titanium Alloys (Ti6Al4V) Aluminum Alloys (AlSi10Mg) Nickel-Based Superalloys (Inconel 625, Inconel 718) Cobalt-Chrome (CoCr28Mo6) Stainless and Tool Steels (17-4PH, 316L, Maraging Steel) 2. Powder Efficiency for R&D
A notable feature of this small-format machine is its reduced powder volume requirement. It can execute builds utilizing up to 80% less metal powder than larger systems, significantly cutting costs when testing exotic or proprietary metal configurations. 3. Near-Net Shape Mechanical Properties
Because the laser completely liquifies the target cross-section rather than just sintering it, parts exit the printer with relative densities exceeding 99.9%. Post-processing steps (like stress-relief annealing and hot isostatic pressing) give the parts isotropic mechanical performance and high fatigue limits comparable to wrought or cast components.
