Introduction of SLM

Selective Laser Melting (SLM) technology is specially designed for metal powder printing, which plays an irreplaceable role in modern industrial production. Fig. 1 illustrates the flow of SLM technology. A layer of metal powder is laid, and a high energy laser beam selectively melts the powder under the control of a CAD program. After one layer of sintering is complete, the system lowers the height of one section layer, and then continuously applies powder and scans until the entire part is sintered.

CD BioSciences is a technology company engaged in 3D printing services with a team of experts and many years of experience. CD BioSciences offers almost all commonly used high-quality metal materials and a variety of printing technologies, including SLM, as well as materials that match SLM.

Manufacturing metal parts through 3D printing has been a major concern. At present, the most widely used technologies in the field of metal 3D printing include SLM, DMLS and so on. Among them, SLM is the most widely used technology.

As one of the fastest growing 3D printing technologies, SLM can rapidly process metal powders and obtain the required parts in a relatively short time.


SLM is a metal additive manufacturing technology that has changed the inherent production method of metal parts. Advanced SLM manufacturing technology can build complex parts that would normally take weeks or even months to complete in a very short delivery cycle. SLM printed parts are durable, have excellent metal structural and thermal properties.

It is worth noting that the entire molding process is carried out in a vacuum or chamber, which is filled with protective gas to avoid metal reactions with other gases at high temperatures.

Mostly all common metal powder materials can be printed with SLM. CD BioSciences provides a wide range of high-quality metal materials to bring a complete solution for your production.

  • Aluminium
  • Stainless steel
  • Copper
  • Titanium
  • Cobalt-chromium alloy

Applications of SLM

SLM technology is currently mature in the manufacture of metal molds, prototypes and parts, and it has been widely used in multiple industries.

  • Aerospace industries
  • Electronic
  • Consumer goods
  • Medical instruments

Advantages of SLM

As a widely used metal printing technology, SLM has multiple significant advantages.

  • No mold is required
  • Shorten the delivery cycle
  • Reduce the cost
  • Improve material utilization
  • Manufacture parts with complex structures
  • The density of parts exceeds 99%
  • Outstanding product performance

CD BioSciences provides SLM services that use a high-intensity laser beam to melt metal powder and finally cool and form parts. SLM can efficiently print parts with precise precision, high strength, and other excellent mechanical properties. CD BioSciences is always ready to provide you with SLM technical services.
