Variable powder delivery and ultra-low oxygen content in the build atmosphere among new features.
Utilizing a high-powered fiber laser to print 20µm- to 100µm-thick layers of fully dense metal directly from 3D CAD data, the Renishaw AM250’s fine metal powder melting process offers fast additive manufacturing for metal parts.
 

The AM250’s new third-generation, state-of-the-art technology includes a safe-change filter system to reduce contact with materials. This helps maintain an ultra-low oxygen content in the build atmosphere.  

Many features of the AM250 minimize the cost of ownership, including low gas consumption, affordable filter elements and a durable soft re-coater blade that needs to be replaced less frequently than other models. Designed for ease of use, the touch-screen interface allows users to prepare and clean the printer.   

The ability to quickly change between a diverse array of materials is one of the strongest features of the AM250. Utilizing the AM250’s removable hopper, users can switch between 316L and 17-4PH SS, H13 tool steel, aluminum AL-Si-12, titanium CP, Ti 6AI-4V and 7Nb, cobalt-chrome (ASTM75) and Inconel 718 and 625. The valve interlock system allows for the addition of extra powder during prints. Further, the hazards of sooty emissions and using reactive materials like titanium and aluminum are minimized with the inclusion of a gas knife and a heated build plate.

With a build envelope of 250 mm (X-axis) x 250 mm (Y-axis) x 300-360 mm (Z-axis), the AM250 comes with a 200W or 400W laser and a fully-welded vacuum chamber for low-pressure evacuation. The chamber keeps oxygen concentrations below 50 ppm through low gas consumption to enable safe use of reactive materials, which also allows for better overall mechanical performance and material integrity. 

Users can choose Marcam Autofab or Materialise Magics software to create and upload build files to the machine via a secure network or direct connection. Customers can also trace past products through enhanced process data and event logging, which are now standard features on the AM250. There are more options to customize the AM250, which are available upon request.
