Metal Binder Jetting<\/h2>\nPrinciple & working process<\/h3>\n
During the metal binder jetting process, a binding agent (usually a liquid) serves as an adhesive between layers of powder. A print head moves horizontally along the x and y axes of the machine, depositing layers on the build platform, and binding the material.<\/p>\n
Common applications<\/h3>\n\n- Rapid to fully functional prototypes<\/li>\n
- Rapid tooling, fixtures, and jigs<\/li>\n
- Dense and durable metals used in metal binder jetting make it ideal for end-use products<\/li>\n<\/ul>\n

Binder jetting has a bunch of advantages over other metal manufacturing processes, both additive and subtractive, including:<\/p>\n
\n- Printing supports aren\u2019t always needed, which\u00a0cuts down on material and post-processing time<\/em><\/li>\n
- Binder jet systems\u00a0can recycle and reuse up to 99% of loose powder<\/em><\/li>\n
- Enables engineers to produce\u00a0complex designs<\/strong>\u00a0without increasing costs<\/li>\n
- Can produce\u00a0multiple parts in one print<\/strong>, reducing costs and development time<\/li>\n
- Manufactured parts are isotropic, meaning they\u2019re equally strong in all directions<\/li>\n
- The technology is rapidly advancing, enabling the production of larger parts and opening paths to a wider range of material options<\/li>\n<\/ul>\n
Disadvantages<\/h3>\n
While this type of metal additive manufacturing has many advantages, no process is perfect. Drawbacks of metal binder jetting include:<\/p>\n
\n- Requires\u00a0additional equipment<\/strong>\u00a0for\u00a0post-processing<\/li>\n
- Most post-print processes are manual, though development is underway to automate<\/li>\n
- Equipment costs are greater<\/strong> than that of subtractive manufacturing techniques<\/li>\n<\/ul>\n
Powder Bed Fusion<\/h2>\nPrinciple & working process<\/h3>\n
The powder bed fusion process includes several printing methods, including electron beam melting (EBM), direct metal laser sintering (DMLS)<\/a>, selective laser sintering (SLS)<\/a>, selective laser melting (SLM)<\/a>, and selective heat sintering (SHS). Ultimately, powder bed fusion uses lasers or electron beams to melt and fuse different powder materials.<\/p>\nCommon applications<\/h3>\n\n- End-use parts for automotive, aerospace and other industries<\/li>\n
- Fabrication of jigs and fixtures<\/li>\n
- Orthotics and prosthetics<\/li>\n
- Automation and end-of-arm tooling<\/li>\n
- Molds and investment casting<\/li>\n<\/ul>\n

Powder bed fusion has some of the same advantages as metal binder jetting, including:<\/p>\n
\n- Minimal supports<\/strong>\u00a0are usually needed because the powder acts as an integrated support structure<\/li>\n
- Excess powder can be recycled<\/li>\n<\/ul>\n
Disadvantages<\/h3>\n
As with all additive manufacturing processes, powder bed fusion also has its disadvantages:<\/p>\n
\n- Powder preheating, vacuum generation, and cooling off periods add to the build time, making it one of the slowest additive manufacturing techniques<\/li>\n
- Post-processing steps can lead to increased production time and cost<\/li>\n
- Quality of the surface depends on the grain size of the powder and is similar to processes like sand casting, etc.<\/li>\n<\/ul>\n
Material Extrusion<\/h2>\nPrinciple & working process<\/h3>\n
During the material extrusion process, the material is drawn through a nozzle, heated, and deposited onto the build platform, layer by layer. The nozzle moves horizontally, while the platform moves up and down as each layer is deposited.<\/p>\n
Originally used with plastics and polymers, metals have been added to the list of materials compatible with material extrusion in recent years.<\/p>\n
Common applications<\/h3>\n
