Top 3 Trends in Additive Manufacturing

The additive manufacturing industry will witness excellent results in the market this year. This market is becoming increasingly industrialized because the technology is becoming a production-ready process, less reliant on rapid prototyping activity just like years before.

FREMONT, CA: Additive manufacturing, also known as 3D printing technology, helps create three-dimensional parts from computer-aided design (CAD) models by adding and creating material layer by layer until the physical piece is made. At present, professional 3D printers stimulate innovation and support businesses in various industries such as engineering, manufacturing, dentistry, healthcare, education, entertainment, jewelry, and audiology. Below given are some of the trends in the additive manufacturing industry for the future.

Metal 3D printing

Metal 3D printing allows the appeal of high-performance parts made from steel, titanium, nickel alloys, and aluminum with exotic geometries for demanding, high-value enterprises like aerospace and medical devices. These industries take full advantage of 3D printing in fabricating metal parts that are highly latticed elements and other complex geometries that minimizes the material needs and also the part weight.

The traditional and common processes of metal additive processes are selective laser melting (SLM) and direct metal laser sintering (DMLS). Just like the plastic SLS, these methods create objects from thin layers of powdered metal by melting it using a heat source. If the given metals have a higher melting point, they need more powerful lasers and an industrial environment.

Advances in Materials

Some of the other advanced 3D printing materials allow the digitization of before the analog processes. High-temperature resins are used in low-pressure plastic injection molding and can be used to cast soft metals like pewter. Although the molding quality might not match hard tooling, 3D printed molds provide a crucial need in small and medium production where the cost of tooling might not otherwise be recoverable.

Modular Compact System for Plastic

The third wave of 3D printing techniques to arrive on the desktop is based on selective laser sintering (SLS), which is considered as an essential technology for industrial users. Unlike the other desktop additive manufacturing processes, SLS creates robust parts from thermoplastics like the nylon that is nearly as strong as their injection-molded counterparts. Unfused powder holds workpieces, which facilitates part packing for higher throughput, and allows for a less labor-intensive post-processing workflow.
