Types of Metal 3D Printing Technologies
Different technologies are employed in metal 3D printing, each with its own strengths and weaknesses. Here’s a comparison of the main types:
| Technology | Process | Pros | Cons |
|---|---|---|---|
| Direct Metal Laser Sintering (DMLS) | Uses a laser to fuse metal powder layer by layer. | High precision, excellent surface finish, wide material options. | Requires careful handling of metal powder. |
| Selective Laser Melting (SLM) | Melts metal powder with a laser, achieving full melting of the material. | Creates fully dense parts, excellent mechanical properties. | Expensive and requires a controlled environment. |
| Binder Jetting | A binding agent is deposited onto a powder bed to create layers. | Fast production speed, no supports needed. | Requires post-processing to achieve final strength. |
| Material Jetting | Similar to inkjet printing, but deposits metal material instead of ink. | High accuracy and good surface finish. | Limited material options, often expensive. |
| Electron Beam Melting (EBM) | Uses an electron beam to melt metal powder in a vacuum. | High build speed, excellent for large parts. | Requires specialized environments and handling. |
Factors to Consider When Buying a Metal 3D Printer
When selecting a metal 3D printer, consider the following factors:
