Meltio Engine CNC Integration

Turn any machine tool into an hybrid manufacturing system with no inherent size constraints. The Meltio Engine is the ideal CNC complement for near net shape manufacturing, repair and feature addition.


Hybrid Manufacturing Integration

The most affordable hybrid manufacturing solution, fitting almost any CNC machine in the market. Enable metal 3D printing and machining of complex geometries in a single process step.

Hybrid Manufacturing

Create highly complex parts with machining tolerances in the same process.


Provide new capability to any CNC machine by turning it into an hybrid metal manufacturing system.

Part Repair

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

Geometry Freedom

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 CNC machine are:


  1. Spindle motors can handle the additional weight
  2. Deployment mechanism can be mounted without collitions
  3. Eight unused M-code controlled relays
  4. Ability to add a NO relays to the feed hold
  5. Ability to add feed resume/start buttons
  6. Laser safety windows can be mounted
  7. System can lock all doors and windows
*The integration will require laser safety windows, door safety interlocks and sheet metal protection for any penetrations in the roof or side walls of the machine. These hardware items are to be sourced by the integrator and depend on the CNC machine of choice.

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.

mild steels

Mild Steels

Cheap and ductile, with unparalleled machinability and weldability.

Carbon steels

Carbon Steels
