An All in One (Short) Guide to Additive Manufacturing

3D Printing, more commonly referred to as additive manufacturing, is the various techniques that offer a range of options for manufacturing components and products across a variety of industries. Creating a visual is primarily focused on creating an actual object using the three-dimensional digital model, usually by layering successive layers of a particular material. 

In recent times, 3D printing has gone beyond being a tool merely used for manufacturing and industrial processes. From small-scale businesses to the newest enthusiasts, all are using 3D printing methods to connect processes with ease. Therefore, it is possible to observe an exponential increase in its use and use in every aspect of the socio-economic sector.

Additive Manufacturing Processes

Binder Jetting

This method employs a 3D printing-like head moving along three scales to create an alternating layer of powdered materials and a liquid binder to act as an adhesive.

Directed Energy Deposition

Direct energy deposition for additive manufacturing could be employed with various materials such as polymers, metals, and ceramics. Lasers, electric arcs, or electron beam guns mounted on the arm can move horizontally, melting filament, wire feedstock, or powder to create material while a bed is moved vertically.

Powder Bed Fusion

Powder bed fusion covers many AM techniques, such as direct laser melting and direct metal laser sintering (DMLS) as well as electron beam melting (EBM) and selective laser sintering (SLS) as well as selective heat sintering (SHS). Lasers electron beams (also known as thermal printing heads) are utilized to melt or melt partially thin layers of materials, and then the excess powder is blasted away.

Material Extrusion

The standard AM method uses the spooled polymers, which are drawn or extruded by the nozzle that is heated and placed on a moveable arm. The melted material is formed layer-by-layer as the nozzle is moved horizontally while the bed is moved vertically. The layers bond to each other through temperature control or chemical adhesives.

Vat Polymerisation

The process involves the liquid resin photopolymer to make an object layer-by-layer. Mirrors are employed to emit ultraviolet light that cures each resin layer using photopolymerization.

Sheet Lamination

This is split into two types of technology: ultrasonic additive manufacturing (UAM) and laminated object manufacturing (LOM). Laminated object manufacturing is well-suited to produce items with aesthetic or visual appeal. It utilizes various layers of adhesive and paper. 

Wire Arc Additive Manufacturing

Wire arc additive manufacturing makes use of the power of arc welding and manipulators to produce 3D forms using the process of arc deposition. This method typically utilizes wire as the material source and follows a set process to achieve desired shapes. This process of additive manufacturing is generally done with robot welding equipment.

Benefits of Additive Manufacturing


Additive manufacturing is an excellent option for making prototypes in a short time. Parts are produced directly from the 3D CAD model, which removes the cost and lengthy process of making fixtures or dies.

Aids in The Construction of Complex Geometries

The technology allows designers and engineers to create complex components that are not achievable with other techniques. Complex features and intricate machine component concepts are easily integrated into the design. Parts that used to require assembly and welding or braze several pieces are now made into a single piece, increasing quality, durability, and capacity.

Reduces The Amount of Waste and Weight of Goods

Incorporating organic structures in designs, designers can remove significant weight while maintaining the strength and durability of the product. Manufacturing with additives produces considerably less waste than traditional manufacturing processes.

Applications of Additive Manufacturing


AM is especially suitable for aerospace applications because of its ability to reduce weight and create intricate geometric components like Blisks.


Many different materials are produced additively specifically for the automotive industry, as they can be quickly prototyped to deliver weight reductions and cost savings.


The medical industry is discovering more and more applications for additively-produced components, particularly for implants that are custom-fitted to fit your needs and other devices.
