Aurora Labs, an Australian industrial development company specializing in the development of metal 3D printers, has unveiled further specifics concerning its transition from the RMP-1 printer model to the state-of-the-art AL250 laser powder bed fusion system. The AL250 will augment the company’s printing bureau – broadening its service spectrum thanks to its advanced technical features. This machine will also serve as a demonstration model for potential customers, underscoring its relevance for future machine acquisitions.

The AL250 is equipped with innovative technology that facilitates bidirectional recoating of the powder bed, powered by the MCP technology. This advancement not only shortens recoat durations but also offers the dual advantage of reduced production costs by enabling extended laser exposure times. As a result, it becomes feasible to rapidly prototype and serially produce industry-specific items – offering cost-efficient solutions for fabricating bespoke parts or components that are otherwise elusive via conventional manufacturing routes.

A distinguishing feature of the AL250 is its exclusive powder dosing mechanism. Here, the powder undergoes heating before being transferred to the recoating system, ensuring the powder is at optimal temperatures for even spreading and densification during layer formation. Such consistency in the powder layer is crucial in minimizing mechanical anomalies in components, thereby guaranteeing a consistent and high-quality output.

The AL250 incorporates a build plate heater with a capability of reaching 200°C, which is particularly beneficial for materials research. The machine’s meticulous environmental control measures oversee the circulation and regulation of gases, temperature, and humidity throughout the printing phase within the build chamber.

When it comes to laser prowess, the AL250 boasts a full 1500W per laser – adept at processing highly reflective or conductive powders, including copper. This laser operates at a wavelength of 1064nm and can produce a spot diameter between 75-150 μm. The AL250 also comes with access to efficient and optimized process parameters tailored for processing an array of powder materials.

The AL250 laser powder bed fusion system boasts a generous build envelope measuring 250 x 250 x 300mm (x, y, z), and can achieve layer thicknesses ranging from 30 to 150 μm. In terms of its physical footprint, the machine’s dimensions are 2220mm in width, 1300mm in depth, and 2480mm in height.
