Trunnano 3D Printing

Using energy to fuse a bed of powdered materials into solid, complex shapes is one of the most popular patterns of 3D printing. Learn how it works principle and which solution is right for you. If you’ve heard the term “powder bed fusion” 3D printing but aren’t sure what it means, you’ve come to the right place. Powder bed fusion is becoming an increasingly popular term, but it can refer to several different types of 3D printing.

Several methods of 3D printing, also known as additive manufacturing, use powdered materials that are “fused” layer by layer with energy. After printing, the final part is encased in a “bed” of unused powder that must be dug out.

The International Organization for Standardization (ISO) divides 3D printing technology into seven categories, one of which is called powder bed fusion.

Under the ISO powder bed fusion category, there are:

  • Selective Laser Sintering (SLS) – Polymers
  • Laser Powder Bed Fusion (LPBF) – Metals
  • Electron Beam Melting (EBM) – Metals

Despite ISO’s efforts to clarify, the names of technologies and their variants continue to change in the additive manufacturing industry. Not only do 3D printer manufacturers prefer to give their technology a completely new name, but end users of the technology have also developed new abbreviations to refer to processes and methods.

For example, laser powder bed fusion is the name of a technology (developed in Germany nearly 20 years ago) that uses lasers to fuse metal powders into shapes. However, it is also commonly known as Selective Laser Melting, Direct Metal Laser Sintering, Direct Metal Laser Melting (DMLM), Metal Laser Sintering, etc., depending on the manufacturer, but they are all the same technology.

Metal or plastic powder bed

Lasers are also used for polymer powder bed fusion, often called selective laser sintering (SLS). You may also hear the terms “polymer laser powder bed fusion” and “metal laser powder bed fusion” from people who like precision, but that’s not the norm yet.

To further confuse the topic, other 3D printing technologies include powder beds, not typically considered powder bed fusion. One of them is adhesive jetting. This method uses a liquid adhesive to bind metal, ceramic or plastic powders together. These are not included in ISO’s PBF category because no energy is used to fuse the powder during printing. However, heat is often used after the printing process.

Powder Bed Fusion 3D Printer is a 3D printing technology based on the principle of fusion deposition of powder materials. The printing nozzle moves along a designated path during the printing process, melting and stacking the powder material layer by layer, ultimately forming a three-dimensional solid.

Advantages of powder bed fusion 3D printers

High precision: Thanks to laser beams or electron beams for melting, high-precision printing is possible.

Wide range of materials: print various metals, plastics and other powder materials.

Can process complex structures: Through multi-axis linkage and precision control, complex three-dimensional structures can be printed.

Environmentally friendly: powder materials can be reused, reducing waste.
