Metal 3d Printing


About Metal Printing

Direct metal printing produces high quality complex metal from 3D Cad file. This cutting-edge technology produces integrate shapes using traditional and casting methods. Metal printing allows production of small and complex shapes without tooling. Moreover, it produces high quality parts for manufacturing with tolerance.



Selective Laser Melting (SLM) and Direct Metal Laser Sintering (DMLS) both are metal 3d printing technologies.
DMLS creates a metal part by using heat and pressure from a 3D model. Powdered metal is used for this type of printing process. Any metal alloy can be used to build the part unlike other processes. The size of the metal particles is between 20 to 40 micrometers. A thin layer of metal is spread across the surface to be printed. Laser is used to scan and fuse the metal particles in order to produce the part layer by layer. After the completion of the project, the part is left to cool.



While DSLM works with metal alloys, SLM works with single pure metals. SLM melts the metal powder completely to form a liquid at a single temperature which requires heating the metal powder layers above the melting point of the metal whereas in DLMS, particles inside the metal are fused together at various melting points at molecular level at raised temperatures. SLM process requires high energy. SLM also requires the use of laser to scan and fuse the metal particles together.
Various materials like aluminium, stainless steel 316L, Copper and Brass can be used in metal 3d printing process.

This material has good thermal and mechanical properties and low density. This metal also has high electrical conductivity. This metal is widely used in creating parts of engine, piping work, housing and production industry, ducts etc.

Stainless Steel 316L
This metal has high resistance and hardness. It is widely used in food and medica sector.

It is widely used in wiring and cabling and electronic industry.

It is widely used in 3d printing jewelry, accessories and other decoration items.

Post Processing
Post processing techniques are used to improve the mechanical properties of the printed part and the loose powder is removed as well.
