Multi Jet Fusion


HP Multi Jet Fusion is the technology behind Polyamide (MJF) and Rubber-like (MJF). It’s a powder-based technology but does not use lasers. The powder bed is heated uniformly at the outset. A fusing agent is jetted where particles need to be selectively molten, and a detailing agent is jetted around the contours to improve part resolution. While lamps pass over the surface of the powder bed, the jetted material captures the heat and helps distribute it evenly.

Metal 3D Printing


Metal 3D Printing is a laser-based technology that uses powdered metals. Similar to Laser Sintering, a high-powered laser selectively binds together particles on the powder bed while the machine distributes even layers of metallic powder. Support structures are automatically generated and built simultaneously in the same material and are later manually removed. Once complete, the part undergoes heat treatment.

Metal 3D Printing is the technology used to 3D print Aluminum and Titanium.




Why Knowledge About 3D Printing Technology Matters


All these different technologies might sound confusing, but the important thing to keep in mind is the following: we cannot assume that Steel and Silver will have similar requirements simply because they are both metals. They are printed using different technologies (Laser Sintering and Lost-Wax Casting) and thus some design features will differ. Knowing the background about how these 3D printing technologies work will help you to design better models. It will enable you to understand why specific designs might be printable in some materials but not in others.

This also means that materials that use the same technology such as Gold, Silver, Bronze, Copper and Brass (Lost-Wax Casting) are more likely to share similar design requirements. To learn more about this, simply visit our material pages. Also, keep in mind that with the use of different printers and printing technologies, the maximum printing sizes differ. You can find an overview of these here.

The printers we presented in this article require a lot of investment and are often not economical for private consumers and small businesses. However, thanks to our online 3D printing service, everybody can use our printers and benefit from getting your prints in the best quality in a huge variety of materials.
