Key Integration Requirements

Payload of at least 45 – 60 kg ensures that the robot can follow the additive toolpath precisely.
Position repeatability of ± 0.06 mm according to ISO 9283.

At least 8 Digital I/O configured according to “Communications Protocols Robot Meltio Engine”.
When using OPC DA or Socket as the default communication protocol, Meltio recommends a total of 16 Digital I/O.

The robot and the ositioner must be installed, configured, and calibrated before the Meltio Engine Integration.

Possibility to add safety integration (depending on the integration)

Laser-safe robot cell with a security circuit between the robot controller, the Meltio Engine, and the cell door interlock.
The integrator is responsible for the correct installation and operation of the security system.

*A laser safety enclosure and safety interlocks for the robot cell are not included. These additional hardware items are to be sourced by the integrator or end user customer because they will depend on the final application and installation facilities.

Upgrades and Accessories

Dual Wire:

This option allows to 3D print two wire materials sequentially with very quick wire switches.

Hot Wire:

Programmable power supply that preheats the material to increase the deposition rate.

Laser Alignmet System:

It allows users to calibrate Meltio’s multi-laser deposition head accurately and effortlessly prior to every print.
