About AM250

AM250 laser melting machineThe AM250 features a vacuum chamber evacuation followed by high purity argon gas in order to create a high quality atmosphere, crucial when building in reactive materials such as titanium, where oxygen content must be minimised. Gas consumption is minimised by the use of a fully sealed and welded chamber that also contributes to robustness. Its also possible to run the system with non-reactive materials under nitrogen gas.

The AM250 features an external powder hopper with valve interlocks to allow additional material to be added whilst the process is running. It is possible to remove the hopper for cleaning or to exchange with a secondary hopper for materials change, using the universal lift. The powder overflow containers are outside the chamber and feature isolation valves so that unused materials can be sieved and reintroduced to the process via the hopper while the system is running. The safe change filter and system powder handling, via the glovebox, help to minimise user contact with materials and process emissions.

The AM250 has been designed with the manufacturing industry in mind, with a simple touch screen user interface and robust construction. From series production of implantable devices to complex lattice structures or detailed aerospace geometries, the AM250 is capable of fulfilling the requirements of a manufacturing system. With the extended Z-axis option it is possible to build parts up to a maximum height of 360 mm.

All file and data preparation is done off-line in an office environment and whilst the system can be a tightly controlled manufacturing cell, the file preparation software also features useful process development tools for high level users.
