The most common metal 3D printing type overview

Effective and fast metal 3D printing is undoubtedly the additive-made Holy Grail. The company is engaged in a full arms race to establish the most effective means of shaping metal into a plastic form, and the sales are constantly rising each year. Metal 3D printing will bring a whole new revival to manufacturing. To date, there are many types of metal 3D printing, each with its own advantages and disadvantages. Here are some of the most common types used to digitally produce metallic objects.

Selective laser melting (based on powder bed)

SLM refers to a metal 3D printing method that uses laser melting and composite powders, this method is great for rearrangement of the alloy. SLM is very similar to Direct Metal Laser Sintering and according to rumours the name difference is due a falling out between the parties developing the method and varying patents. Nonetheless, both methods make use of lasers to arrange a wide spectrum of alloys.

Selective Laser Sintering (Powder Bed Based)

Although mainly used for plastics, SLS can also be used for certain types of metals. SLS and SLM are the most common means of metal 3D printing, also known as direct metal laser sintering (DMLS) and direct metal laser melting (DMLM), these methods are very similar to the places often confused with each other. The difference is what material they affect. SLM sinter powders make them suitable for alloys rather than SLS for single elemental metals and certain alloys. SLS shows a wider range of material powders that can be used and can achieve varying degrees of density when creating structures. Another difference is that SLS requires the element to completely melt.

Robocasting

Mechanical engraving is a rather vague practice for making certain types of ceramic molds or lamellar inks with a variety of materials. Thin nozzles allow for very precise mode of action, carefully designed by the printer. Nitrides, metals and composites have been used in this method. The strength of the final product is very high, and this method is highly efficient.

Cold spray metal printing

This is one of the fastest ways to print metal. Cold jet printing refers to the means of emitting particles at a surface to form a physical object. It was originally used by NASA to build metal objects in space. It was recently used on the LightSpee3D printer.

Adhesive Jetting and Ink Jet 3D Printing

This metallic 3D printing method was first developed at MIT, instead of laser technology that uses adhesives, it’s like SLS. One of its greatest strengths is the speed at which it generates the model.
