3D MOULDING

TRADITIONAL MANUFACTURING

ADDITIVE MANUFACTURING

3D Printing is the process of making a physical object from a three-dimensional digital model, typically by laying down many thin layers of a material in succession.

FUSED DESPOSITION MODELING

The FDM printing process starts with a string of solid material called the filament. The material in the form of filament is being melted and extruded through a nozzle to 3D print a cross section of an object each layer at a time. As the material is extruded as a layer of the object on this path, it instantly cools down and solidifies – providing the foundation for the next layer of material until the entire object is manufactured.

Steriolithography (SLA)

Build platform is submerged into a translucent tank filled with liquid resin.A light located inside the machine maps each layer.Mapped layer is solidified by the light source.The platform lifts up and lets a new layer of resin flow beneath the object

SELECTIVE LASER SINTERING (SLS)

1. Powder is dispersed in the build chamber.

2. The printer preheats the powder to a temperature just below the melting point

3. The laser scans a cross-section of the 3D model, heating the powder to just below the melting point

4. The platform lowers by one layer into the build chamber, typically between 50 to 200 micron.

5. Recoater applies a new layer of powder on top.

6. The laser then scans the next cross-section of the build. and this process repeats for each layer until parts are complete
