Different 3D Printing Process For Various Applications

Manufacturing Technology Insights | Friday, September 16, 2022

Manufacturing businesses can now choose from a variety of options of 3D printing technology according to their business needs

FREMONT, CA: There are three main technologies that 3D printing enthusiasts utilise largely despite a wide range of 3D printer types. This includes fused deposition modelling (FDM), stereolithography (SLA), and selective laser sintering (SLS). Selecting an appropriate 3D printing process for specific business applications requires a precise understanding of each process’ strengths and weaknesses and directing those attributes to product development needs. Therefore, it is necessary to understand the different types of 3D printing technologies available and their implications in the manufacturing industry.

Vat Polymerization

Vat polymerisation uses a liquid starting material that solidifies when exposed to light. Lasers and other precision lighting are used to cure photopolymer resins that sit in a vat by using a bed that slowly lifts an object as it is made. Vat polymerisation 3D printing is popular for producing subtle parts without noticeable layer lines, which makes SLA and DLP different from FDM 3D printing.

Powder Bed Fusion

Powder bed fusion is a unique type of 3D printing technology. These printers use powdered materials that are fused with thermal energy instead of using filament or resin. This makes it possible to print objects made of metal and ceramic and eliminates the need for cumbersome supports because the powder performs the work.

Material Jetting (MJ)

Material jetting 3D printers operate similarly to regular 2D printers. It uses lasers or digital light projectors to deposit liquid material onto a building plate and cure it with precise jets that lay the material down layer by layer. A drop of demand material jetting can even deposit polymer and wax materials to make supports.

Binder Jetting

Binder jetting stands between material jetting and powder bed fusion. A build plate consists of layers of powdered material, and nozzle jetting binding material into particular locations constructs each layer of the finished model. This process uses sand, metal, and polymers, although each material requires its equipment to operate.

Direct nergy Deposition (DED)

DED 3D printers work like FDM printers. A nozzle moves around a print bed while installing materials in layers to create a model. Direct energy deposition 3D printers use heated metal powder or wire and fuse as it leaves the nozzle instead of using meta-plastic filament. Such printers heat the material with a laser, electron, or plasma beam.

Sheet Lamination

With the help of a laser cutter or CNC machine, sheet lamination cuts a shape after layers of paper, plastic, or metal are laminated using glue, heat, or sound. This 3D printing method is cost-effective and fast compared to other techniques.
