Manufacturing with Meltio
2. About
Our mission is to delight customers, partners and employees by
pioneering the development of affordable metal 3D printing
solutions
that are reliable, safe and easy to use, continually reinforcing our
status
as disruptors.
3. Last 18 months…
>70 Employees >125 Systems Sold >35 Partners for local sales,
integration, service and support
4. Metal additive manufacturing barriers for industrial adoption
Limited Part Size and
Part Properties
High Investment, Development and Running
Costs
Subpar User Experience and
Convenience
5. Multi-Laser Deposition Head
Meltio’s technology comes packaged in a compact 1.2kW deposition head, host of multiple lasers and capable of processing wire and powder
independently or simultaneously.
Integration Ready
Turn an existing CNC or robotic platform into an hybrid
manufacturing system with no inherentsize constraints.
Safe and Reliable
The bulk of the 3D printing process is built around
wire, the safest, cleanest and easiest to work with
metal feedstock.
Multi-metal 3D Printing
Print dual wire for hard-facing or anti-corrosion
applications, or wire and powder to create new
alloys on the fly.
6. Metal 3D Printing Solutions
A package that suits every requirement; turn-key metal 3D printer, CNC integration for hybrid manufacturing or
robotic integration for large components.

13. Meltio 3D Printing Process
The only process able to deliver strong, affordable and fully dense metal parts within a few hours
1
Print
With steels, titanium, inconel, copper* and aluminum*
alloys
2
Post-process
With heat treatment, CNC machining, bead blasting,
polishing…
3
Cut
Remove the build plate using a band saw or wire EDM
*Under Development: expected to
be released in 2021.
14. Single and Dual Metal 3D Printing
Meltio recommends printing the bulk of the parts with metallic wire. If the desired build material is not available
in wire form, powder can be used.
Dual Wire
Combine different metal materials in a single part. The
wire switching process is quick, automatic and clean.
Single Wire
The bulk of the 3D printing process is built around
wire, the safest, cleanest and easiest to work with
metal feedstock.
Wire and Powder
Create new alloys on the fly, test functional
gradients and research metal matrix composites
(MMC).
15. Open Materials Platform
Stainless Steels,Wire & Powder
Fully supported: 316L (EN 1.4404), 308L (EN1.4316) and 304L
(EN 1.4307)
Titanium, Wire
Fully supported: Titanium Grade 5 (EN 3.7165)
Inconel, Wire & Powder
Fully supported: Inconel 718 and Inconel 625 (EN 2.4668)
Carbon Steels, Wire & Powder
Fully supported: SAE 4140 (EN 1.7225), and A-5.18:ER70S-6
(EN 1.5130)
Copper, Wire & Powder
Under Development: expected to be released by the end of
2021.
Aluminum, Wire
Under Development: expected to be released by the end of
2021.
16. From 0.3 to 1.2mm layer
heights
Under some conditions, Meltio’s
using wire outperforms those
based processes.
Consistent 99.998%
densification
Meltio’s WP-LMD produces fully
dense parts with superior
microstructure.
Post-process when
necessary
Meltio’s WP-LMD overthickness is
homogenous and for applications
printed in high-resolution only post-
treatment of critical areas is
necessary.
Excellent Mechanical Properties
Meltio’s compact heat affected zone process achieves exceptional mechanics, decreased
thermal stress and near isotropic properties, exceeding casting and forging material
properties.
18. It can also be used for small
and medium sized parts
Can achieve very smooth
surface finishes
Only requires 1.5mm extra
stock

21. Seamless integration of encoder in shaft for rotation and position measurement.
- Part was printed in two materials.
- The shaft is made from stainless steel 316L (non-magnetic)
- The inserts are printed from mild steel. (magnetic)
- A hall effect sensor is used to detect the position and speed of the shaft.
- Because the mild steel inserts are completely covered by the stainless steel
shaft, corrosion performance of the shaft is preserved.
