1 . Vat Polymerisation : This process uses a vat of liquid photopolymer resin , then the model is constructed layer by layer .
2 . Material Jetting : This process creates objects in a similar method to a twodimensional inkjet printer . Material is jetted onto a build platform using either a continuous or Drop-on-Demand ( DOD ) approach .
3 . Binder Jetting Process : This uses two materials ; a powder-based material and a binder . The binder is usually in liquid form and the build material in powder form . A print head moves horizontally along the x and y axes of the machine and deposits alternating layers of the build material and the binding material .
4 . Material Extrusion : Fuse deposition modelling ( FDM ) is a common material extrusion process . Material is drawn through a nozzle , where it is heated and then deposited layer by layer . The nozzle can move horizontally and a platform moves up and down vertically after each new layer is deposited .
5 . Powder Bed Fusion : This process includes the following commonly used printing techniques : Direct metal laser sintering ( DMLS ); electron beam melting ( EBM ); selective heat sintering ( SHS ); selective laser melting ( SLM ) and selective laser sintering ( SLS ).
7 . Directed Energy Deposition ( DED ): This covers a range of terminology such as laser-engineered net shaping ; directed light fabrication ; direct metal deposition ; 3D laser cladding etc . It is a more complex printing process commonly used to repair or add additional material to existing components .
Global market size
“ Additive manufacturing revolves around the creation of an object by generating one layer at a time . The emergence of 3D printing with technological advances has highlighted the importance of additive manufacturing processes . Additive manufacturing is basically made to scale the model of the final product at a robust pace without the cost of creating a prototype and a typical set-up process . This saves the overall cost of the manufacturing process by promoting speedy manufacturing for end-user industries ,” outlined analyst , Precedence Research .
According to Precedence Research , the
3D-printed part from ProtoLabs . global additive manufacturing market size was evaluated at US $ 17.99 billion in 2023 and is expected to reach around US $ 110.13 billion by 2033 , poised to grow at a CAGR of 19.85 % during the forecast period ( 2024 to 2033 ). “ North America led the market and contributed more than 36.14 % in 2023 . The Asia-Pacific region is expected to witness the highest CAGR throughout the forecast period . By component , the hardware segment captured the largest market share of 61 % in 2023 . By component , the software segment is expected to expand at the fastest CAGR of growth during the forecast period ,” outlined the analyst .
“ The industrial 3D printer segment registered more than 65 % of revenue share in 2023 . The desktop 3D printer segment is expected to grow at a significant CAGR during the forecast period . By technology , the stereolithography segment led the global market in 2023 ,” it added .
In its new ‘ Additive Manufacturing Market ’ report , the analyst further confirmed that ( by application ) the prototyping segment led the
6 . Sheet Lamination : These processes include ultrasonic additive manufacturing ( UAM ) and laminated object manufacturing ( LOM ). The Ultrasonic Additive Manufacturing process uses sheets or ribbons of metal , which are bound together using ultrasonic welding .
