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 capable machines in its class, this Laser Powder Bed Fusion (LPBF) machine delivers exceptional accuracy, efficiency, and material performance, setting new standards for productivity in modern manufacturing.

High Build Volume & High Throughput Productivity

As a high build volume metal 3D printer, the STLR 400 offers a spacious build area designed for both large-format components and high-density batch production.
Manufacturers can:

• Print large aerospace brackets, structural parts, or tooling inserts

• Nest multiple automotive or medical components in a single job

• Maximize powder usage efficiency

• Reduce operational cost per part

This level of scalability makes the STLR 400 ideal for both rapid prototyping and full-scale industrial production, delivering consistent, repeatable performance across every build.

Intelligent Powder Handling & Advanced Safety Systems

One of the standout features of the STLR 400 is its fully enclosed automated powder handling system — a crucial advantage when working with reactive metals such as Aluminum (AlSi10Mg) and Titanium alloys.

The system includes:

• Fully sealed powder flow and recovery

• Nanoscopic sensors that monitor powder distribution in real-time

• Automatic dosing to ensure optimal powder usage

• Minimal operator exposure, improving workplace safety

This engineering focus ensures stable builds, cleaner handling, and long-term reliability for industries operating under strict safety and material quality standards.

Versatility for R&D and Production

While the STLR 400 is a powerful production machine, it also excels in material research and process development.
Its specialized part volume reducer significantly lowers powder consumption during small-scale tests. This is ideal for:

• Experimenting with new alloys

• Testing parameter sets

• Developing material behaviors

• Academic or industrial R&D labs

The printer can efficiently handle powders with particle sizes down to 75 μm, enabling finer details, superior surface finish, and improved metallurgical performance.

Wide Material Compatibility for Multiple Industries

The STLR 400 supports an extensive material portfolio, making it suitable for a broad range of industrial and creative applications. Compatible materials include:

• AlSi10Mg for lightweight automotive & aerospace

• Stainless steels for tooling & general engineering

• Titanium alloys (Ti6Al4V) for aerospace & medical implants

• Precious metals (Gold, etc.) for jewelry & high-value products

This flexibility allows manufacturers to deploy one printer across multiple product lines and application categories.

Why Choose the STLR 400?

• • High-speed dual-laser 3D printing system for significantly reduced build times

  • Large-format build volume enabling bigger parts and higher batch output

  • Enclosed, automated powder handling ensures operator safety and material consistency

  • Wide material compatibility spanning industrial metals to specialty alloys

  • Perfect for both industrial-scale production and R&D environments

  The STLR 400 is not just a machine it is a complete solution that merges precision engineering, automation, and material innovation, empowering manufacturers to achieve world class performance in metal additive manufacturing for aerospace, automotive, tooling, medical, and other advanced sectors.
