STLR 400: Advanced 3D Metal Printer for Industrial Manufacturing
The STLR 400 is the latest innovation in industrial 3D metal printer, designed to meet the high-performance demands of sectors such as Aerospace and Defence, Automotive, Medical, General Engineering, Die & Mould and etc. As one of the most advanced machines in its class, the STLR 400 combines precision engineering, cutting-edge technology, and user-centric design to redefine productivity and quality in additive manufacturing.
High Build Volume & Productivity 3D Metal Printer
With a class-leading build volume, the STLR 400 allows manufacturers to print large metal parts or nest multiple components in a single run. This enhances throughput while maximizing material utilization—making it an excellent choice for both prototyping and full-scale production. Whether you’re building large aerospace brackets or multiple automotive components, the STLR 400 delivers consistent results.
Intelligent Powder Handling & Safety
A standout feature of the STLR 400 is its automated powder handling system. The entire process is enclosed, reducing exposure and improving operational safety—an essential advantage in environments working with reactive metals like Aluminum or Titanium. Nanoscopic sensors monitor and regulate powder flow in real time, ensuring the precise amount of material is used throughout the build.
Versatility for R&D and Production 3D Metal Printer
Beyond production, the STLR 400 supports research and development with its part volume reducer, which allows for smaller builds and minimal powder usage—ideal for testing new materials, alloys, or process parameters. Powder preparation supports particle sizes down to 75μm, allowing for finer detail and better surface finishes.
Broad Material Compatibility
The STLR 400 supports a wide range of metal powders, including AlSi10Mg, stainless steel, titanium alloys, and even precious metals like gold. This material flexibility makes it suitable for everything from industrial tooling to medical implants and custom jewelry applications.
