Different Types of 3D Printing and Rapid Prototyping

1. Different Types of 3D Printing and Rapid Prototyping The 3D printing industry has come a long way since its introduction. In fact, the global market is currently worth about USD 13 billion, expected to grow by 20.8% in 2030. One common misconception is that 3D printing only refers to a specific process. But did you know that there are several types of 3D printing and rapid prototyping? Get to know the different types of 3D printing and rapid prototyping  Stereolithography (SLA) SLA is the oldest form of 3D printing. An SLA printer uses galvanometers and lasers to selectively cure and solidify parts, resulting in a final product with a smooth surface finish and extreme detail. Generally, SLA printing is used to manufacture anatomical models and microfluidics for the medical industry.  Selective laser sintering (SLS) SLS is a 3D printing process that melts nylon-based powders to form solid plastic parts. This method is ideal for manufacturing durable prototypes, typically those used for functional testing. Another advantage of SLS is its efficiency. The process does not require support structures, and as a result, you can use the entire build platform to create multiple parts.  Fused deposition modeling (FDM) When most people think of 3D printing, they are actually envisioning FDM. This process extrudes molten plastic filament one layer at a time on a build platform, slowly forming a complete product. FDM is widely preferred by manufacturers aiming to produce physical models and prototypes. However, this method is not ideal for functional testing due to limited technology and poor strength.  MultiJet Fusion (MJF)

2. MJF is very similar to SLS, able to build functional parts out of nylon powder. However, this process uses an inkjet printer rather than a laser. As a result, the final products produced by MJF tend to be more consistent with a better surface finish.  Direct metal laser sintering (DMLS) Unlike the previously mentioned methods, which mostly use plastic, DMLS is a metal 3D printing process. DMLS is an excellent alternative for multi-part assembly methods, allowing manufacturers to integrate several parts into a single component and reduce material waste. There are many other types of3D printing and rapid prototyping; however, the ones mentioned above are the most common.
