300 Family

The system is equipped with an automatic working chamber extraction system, which allows to remove at the end of the job the entire working chamber with the component and the remaining powder inside, to speed up the set-up activities for a new job, increasing the overall productivity of the system and allowing depowdering activities to be carried out in an external system. 

It is possible, on request, to reduce the production area of ​​the system according to the customer's needs.

There are several options for powder handling:

• Manual: the machine is equipped with a hopper filled manually by the operator, which automatically feeds the machine to complete an entire job
• Semi-automatic: the powder is inserted into the system thanks to a pneumatic conveyor that automatically collects the powder from an external hopper that can be filled manually, which can have customized dimensions according to production needs
• Automatic: the system is fed with a pneumatic conveyor that collects the powder from a hopper fed in a closed loop and in an inert atmosphere by another independent pneumatic conveyor that recovers the powder directly from the sieve

The machine, in its multilaser version, can operate with all laser sources simultaneously during the print job, with the lasers working on the same work area according to two possible strategies that can be set by the user: quality mode and production mode.

Bidirectional recoating.

The laser sources are air-cooled, therefore they do not require any additional external units.

Open parameters, suitable for carrying out research and development activities on the process and on materials.

The filter unit is optimized to consume as little nitrogen or argon as possible, with a filter cartridge system that reduces the number of filter changes and the time required to change each cartridge (about 10 minutes each) to meet production needs. and those of the 4 lasers without compromising print quality, thanks also to the cyclonic system that prevents dust residues from ending up in the cartridges. The filter unit also has an automatic backflushing function, which allows you to unclog the filter cores during the process, in order not to interrupt printing. The filter unit includes automatic passivation of the filter cartridge to eliminate any safety issues when replacing the filter cartridge.
