/ Meltio · Wire-Laser Metal Deposition Engine Robot

Engine Robot Integration.
No size limit on your existing robot.

An integration kit that converts any common industrial robot arm — ABB, KUKA, Fanuc, Yaskawa, Siemens — into a metal AM system. The working envelope is bounded only by the reach of your robot, not by a chamber. Ideal for cladding, hard-facing and large geometries that an M600 or LPBF machine cannot handle. Plus plug-and-play robot mounting on a gantry for parts of multiple meters.

Working envelope = reach of your robot. No chamber limit, no size restriction. On a 6-axis robot arm or longer on a gantry — meters possible.
Compatible with all common robot brands. ABB, KUKA, Fanuc, Yaskawa, Siemens — validated integrations available.
Printhead 20.5 – 23 kg, robot-mounted. Lighter than the CNC variant, optimized for robot tip-load while retaining Blue Laser 1.4 kW.
Meltio Space slicer · 1 year included. Multi-axis toolpath generator specialized for robot integrations with simulation and collision detection.

[ 02 · Why this configuration ]

Four properties that drive the choice

/ 01

No size limit

Parts that physically do not fit in M600 or LPBF machines become makeable here. On a gantry, parts of multiple meters are realistic.

/ 02

Cladding on large geometry

Repair and cladding of components too large to bring to an AM machine — bearings of meters, shipbuilding parts, civil steel structures.

/ 03

Existing robot investment

Already have an industrial robot in your production? The Engine Robot kit leverages that investment — no second machine, no extra footprint.

/ 04

Plug-and-play software

Meltio Space (1 year included) is a multi-axis toolpath generator specialized for robot integrations — simulation, collision detection, and post-processor for your specific robot brand.

See how the Engine Robot works

The Meltio Engine integrated on an industrial robot arm — multi-axis deposition paths, near-net-shape build-up, and the flexibility of a robotic cell platform in production.

[ 03 · Applications ]

Where this configuration pays off

Three typical scenarios where the Engine Robot is the right choice for your production.

Application 01

Cladding on large bearings and shafts

White metal (babbitt) cladding or CRA cladding on industrial bearings, propeller shaft segments, or large hydraulic cylinders. A use case where Eurobearings (IT) reduced their lead time by 50% via a KUKA + Engine Robot setup.

Heavy industry · Marine · Energy
Application 02

Large structural parts

Wing spars, structural aerospace components, civil steel structures — geometries that simply do not fit in a chamber. On a gantry-mounted robot, parts of meters become possible.

Aerospace · Civil · Defense
Application 03

Hard-facing in production

Hard-facing cladding on valve seats, cutting tools, drilling tools — applications where high deposition rate and multi-material flexibility are decisive.

Oil & Gas · Mining · Tooling
[ Printed with Meltio ]

Complex geometry with 6+ axes.

With a 6-axis robot, optionally combined with a positioner, the print head moves around the part. This lets you print rotating and overhanging shapes such as nozzles, turbines and exhaust parts without supports.

What 3DPS does for Engine Robot customers

/ Before

Robot assessment

Before purchase we evaluate your existing robot installation — brand, payload, reach, controller version. No integration if the foundation is not right.

/ Purchase

Cell design & integration

We design a safe cell setup with you: shroud system, gas supply, feeder positioning, plus mechanical and software integration.

/ Roll-out

Multi-axis training

5-day training including Meltio Space toolpath generation, robot programming, and multi-axis printing strategies for your specific parts.

/ Operational

Maintenance + Space license

Preventive maintenance of the printhead and feeders, plus annual renewal of the Meltio Space license. Spares within 48 hours.
