Metal 3D Printing Service

What is metal 3D printing?

Metal 3D printing is an additive manufacturing process that produces parts by fusing metal particles together layer by layer to form a metal part. It is often chosen as an alternative to CNC machining or metal casting because it can produce parts with the strength and durability of metal , while also taking advantage of the design freedom 3D printing offers. It can generate complex designs, including lattice and topology-generated structures, neither of which can be fabricated by traditional CNC machining.

The advantages of metal 3D printing

Metal 3D printing has advantages because it can produce high-performance, complex metal parts suitable for a variety of end environments. Metal 3D printed parts are isotropic, meaning they have uniform multi-directional strength and the superior mechanical properties of metals such as aluminum, stainless steel, titanium, Inconel, tool steel and stainless steel-bronze composites.

3D metal printing can also be used to combine multiple assembly components into a single part. This generally results in a stronger structure by reducing the points of failure introduced by threads and inserts.

With metal 3D printing, CAD file information is sent directly to the printer, which means parts are often cheaper and faster than producing machined metal parts. Machined metal parts have overhead costs such as tool setup and longer machining times.

Aluminium Alloy 3D Printing Services

Aluminium (AlSi₁₀Mg) is widely used in metal 3D printing, due to its strength, low-weight and good thermal properties. Unlike traditional shinny milled aluminium, 3D printed aluminium has matte gray, slight rough and less defined surface. The aluminium alloy 3D printing service is popular in the metal 3D printing service of Kesu Group. The main materials are AlSi12 and AlSi10Mg.

Stainless Steel 3D Printing Services

Stainless Steel as the normal material of 3D printing is commonly used in the direct metal laser sintering (DMLS) or selective laser sintering (SLM) process. The most commonly used stainless steels are 17-4ph and 316L. The stainless steel 3D printing service is a common used metal 3D printing solution in Kesu Group.

Die Steel 3D Printing Services

Die Steel 3D Printing Service is very popular in rapid prototyping. Die steel is  widely used in the manufacturing of tooling elements such as cores and inserts of die casting and injection moulding tools. The 3D printing metal powder, EOS Maraging Steel MS1, which is a fine powder form of maraging steel. The composition of MS1 mold steel corresponds to American classification standard 18 maraging steel 300, European 1.2709 and German X3NCoMoTi18-9-5. This steel is characterized by very good mechanical properties, and can be  heat treated easily. The excellent hardness and strength can be earned by using a simple heat age hardening treatment. The parts made of MS1 die steel have good machinability, and the hardness that can be obtained by age hardening is about 55HRC. This steel is commonly used in complex tools, but also in high-performance industrial products such as in aerospace applications.

Titanium Alloy 3D Printing Services

Titanium 6AI-4V is the ideal material of 3D Printing, which composed mainly of Titanium (88-90%), Aluminum (5.50-6.5%) and Vanadium (3.50-4.50%).  This grade 5, titanium alloy has great strength, high resistance to  oxidation and acid, lightweight which density of 4.41g/cm3. The 3D printed titanium parts has great advantage on aerospace, as one kilogram reduction of spacecraft could lower the launch costs 20,000 US dollars, thus each gram in lightweight design counts. The main metal 3D printing service of Kesu Group is on titanium alloy.
