Meltio Engine Robot Integration

Turn a robot arm into a metal 3D printing system with no inherent size constraints. The Meltio Engine Robot Integration is the perfect platform for large and complex 3D printing, repair, cladding and feature addition.


Robotic Metal 3D Printing Integration

The most affordable large scale metal 3D printing solution, the Meltio Engine integrates with any robot arm manufacturer and interface in the market.

High Complexity

Create highly complex parts with infinite degrees of freedom.


Provide new capability to any robot arm by turning it into a metal 3D printing system.

Part Repair

Cost-effective component repair, part augmentation and feature addition.

Large Size

No inherent constraints when the working envelope is only limited by the size of the motion system.

Minimum requirements for a successful integration of the Meltio Engine with a robot arm are:


  1. Payload of at least 20kg (60kg recommended)
  2. More than 3 digital input ports available
  3. More than 3 digital output ports available
  4. Enclosed room with safety locks
  5. Laser safe windows and/or camera
*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.

Open Materials Platform

Meltio recommends printing the bulk of the parts with metallic wire – the cleanest, safest and lowest cost metal feedstock in the market.
