It is possible to 3D print with almost any material. This technology also offers many 3D printing material possibilities. Prototyping-which is one of the most popular professional uses for 3D printing-can be done in-house with little to no lead time, and design iterations can be implemented and printed on the spot.
Although 3D Printing an object can take hours or even entire days, it is still much faster than mainstream production methods such as injection molding. Why use 3D Printing?ģD Printing offers a considerable number of advantages, the most significant one being the ability to produce highly complex designs that would be impossible to make otherwise.Īnother significant benefit of 3D printing is speed. These 3D printing technologies each have their own strengths and weaknesses and can adapt to different use cases and industries. Material or binder jetting, where tiny droplets of material are deposited onto a bed of powder.PBF (powder bed fusion), a range of powder-based methods that fuse particles with powerful lasers.SLA (stereolithography), a technology that solidifies the photosensitive resin.FFF (fused filament fabrication) or FDM (fused deposition modeling), which use spools of filament.The leading 3D printing technologies available today are: There are different ways to 3D print objects. The layers are consecutively 3D printed one at a time until you obtain the fully printed object. For example, if you were 3D Printing a pyramid, the first layer (bottom) would be a flat square, and the last layer (at the very top) would be a tiny dot. This 3D printing format is a language that the 3D printer reads to know precisely when and where to deposit material.Įach layer corresponds to the exact 2D shape of one section or slice of the object. How does 3D printing work?Ī digital 3D model is sliced into hundreds of thin layers by dedicated software to export in G-code format. While 3D printing started out as a slow and costly technique, extensive technological developments have made today’s AM technologies more affordable and faster than ever. This technology has been around for about four decades, invented in the early 1980s. 3D Printing is called additive manufacturing (AM) instead of traditional subtractive methods like CNC milling when used for industrial production. 3D Printing is the process of creating objects by depositing layers of material on top of one another.
