Metal printing - 3Dbgprint

Metal printing is one of the rarest 3D printing technologies. The metal powder is bonded by laser sintering to form the object. This technology produces highly detailed objects directly into metal without the limitations of CNC tools, die casting or other traditional methods of metal production.

In Laser Metal Fusion technology, also known as selective laser melting, the laser heats the metal dust by melting it right on the site, according to CAD data, and attaches certain points to the bottom layer. This means that the powder is not just heated, but is actually melted in a homogeneous medium with the bottom layer. Which allows the use of pure metal powder materials, in addition to metal alloys.

Metal printing materials

Steel SS316L

Steel SS316L

SS316L ( AISI316L / 1.4404 ) a low-carbon alloy of stainless steel also known as 1.4404, is highly corrosion-resistant and offers excellent strength. 3D-printed stainless steel has high ductility and good thermal properties. Stainless steel can be used for food-safe applications, machine components and production tools. Other applications include ductwork, durable prototypes, spare parts, medical instruments and wearables.

Advantages of Steel SS316L

Excellent strength, high ductility & good thermal properties
Highly corrosion-resistant
Lead time: 10 working days
Maximum part dimensions: 250 x 250 x 280 mm

Industry-standard quality requirements
Ideal for prototypes and simple end-parts
Form-, fit- and function-testing
Strength and density similar to cast parts

Inconel 718C

Inconel 718C

Inconel 718 (Inconel 718 / 2.4668) exhibits an exceptional thermal resistance, up to 700°C, and high resistance to oxidation and corrosion. It also offers excellent strength, with high yield, tensile and creep-rupture properties. 3D-printed Inconel retains strength over a wide temperature range, making IN718 an attractive choice for extreme environments, whether in high-temperature applications like turbines and engine parts or low-temperature applications like cryogenic environments. Inconel is ideal for the aerospace and automotive industries, with common applications including ductwork, valves and heat exchangers.

Advantages of Inconel 718C

Exceptional thermal resistance up to 700°C
High yield, tensile and creep-rupture properties
Long-duration strength at extreme temperatures

Interlocking Parts – No
Unfinished parts typically have a rough surface
Various finishing degrees can achieve smooth surfaces

PRINTERS – MYSINT 200 / MYSINT 100

MYSINT 200

MYSINT, the new family of SISMA 3D printers with selective metal powder bed fusion laser – Laser Metal Fusion. MYSINT 200, together with EVERES, represent the latest generation of 3D printers offered by SISMA and is part of a larger project, in which these two product classes pursue a unique and specialized dimension, in order to generate added value to its users.

MYSINT 3D printers are state-of-the-art production solutions, representing the most advanced technology on the market today for the production of three-dimensional metal artefacts. They guarantee the highest standards both in the monitoring of the process, where the operating parameters are displayed in progress and made available in a final summary, and in the monitoring of the melt pool, where the joint use of video cameras and software allow for instant verification of the quality of fusion and process stability.

The brand new MYSINT 200 series, which is designed to best meet the production needs of the industrial and medical sector by also working with reactive metals, offers a maximum printing volume equal to a cylinder with a base diameter of 200 mm and a height of 200 mm.

250% load factor
A powder loading tank large enough to supply up to two and a half times the maximum printable volume.

Full control
In the print settings configuration, with any type of metal powder available on the market.

Optimal density
A new gas flow management system inside the printing chamber allows optimal density to be obtained over the entire working area, without soiling the laser protection lens.

MYSINT 200 allows out of the ordinary production performance to be achieved, thanks to:

Two fully overlapping laser sources that work together (full overlap).
State-of-the-art laser pulse management functions, allowing a better surface finish to be obtained and stress to be reduced during construction of the piece.
Pre-heating of the printing plate up to + 200°C.
The components and the industrial category control computer, which guarantee greater process stability.
Two filter cartridges that support up to 1000 hours of printing each.
An integrated suction system for the transfer of residual dust from the construction cylinder to the recovery container, without the need to use an external discharge station.
A meltpool monitoring system to analyze the laser beam and verify the actual work quality
An external dust management system through the MYSINT MULTIPLO station for automatic sieving, even in an inert atmosphere.

MYSINT 100

3D selective laser fusion printer for metal powder.

Productive
Thanks to the patented Tilting Coater, MYSINT100 offers reduced re-coating times, increasing the production capacity.

Versatile
Each machining parameter and the entire production strategy are fully customizable to adapt to every specific need.

Reliable
The stable and uniform flow of inert gases ensures the best fusion stability minimizing consumption (patented system).
