Electroplating, also known as electrochemical deposition or electrodeposition, is a process for producing a metal coating on a solid substrate through the reduction of cations of that metal by means of a direct electric current.
When the nozzle approaches the substrate, the meniscus is formed at the nozzle tip, and functions as a confined electrodeposition bath. A two-electrode configuration was employed for the L-PED process, consists of a working electrode (the substrate) and a counter electrode (a metal wire which is inserted within the micropipette).
Laser metal deposition (LMD) is an additive manufacturing process in which a feedstock material (typically a powder) is melted with a laser and then deposited onto a substrate. [1] A variety of pure metals and alloys can be used as the feedstock, as well as composite materials such as metal matrix composites.
Electroless deposition is an important process in the electronic industry for metallization of substrates. Other metallization of substrates also include physical vapor deposition (PVD), chemical vapor deposition (CVD), and electroplating which produce thin metal films but require high temperature, vacuum, and a power source respectively.

EBF 3 uses a similar process, starting with a CAD model, numerically reducing it into layers, then using a post-processor to write the G-code defining the deposition path and process parameters for the EBF 3 equipment. [5] It uses a focused electron beam in a vacuum environment to create a molten pool on a metallic substrate.
Printing: The process begins with printing the part using a filament containing metal powder bound in plastic. This filament, similar to that used in conventional FFF printers, is infused with metal. The printer deposits the metal-infused filament layer by layer, building up the shape of the part. These printed parts are referred to as "green ...
Chemical Bath Deposition has a long history but until recently was an uncommon method of thin-film deposition. [1]In 1865, Justus Liebig published an article describing the use of Chemical Bath Deposition to silver mirrors (to affix a reflective layer of silver to the back of glass to form a mirror), [5] though in the modern day electroplating and vacuum deposition are more common.
Cathodic arc deposition or Arc-PVD is a physical vapor deposition technique in which an electric arc is used to vaporize material from a cathode target. The vaporized material then condenses on a substrate, forming a thin film. The technique can be used to deposit metallic, ceramic, and composite films.
