3D printing is a group of technologies which produce real parts from the computer data in the shortest time and at the highest possible quality. The components are fully functional and it can be so close to the final product, which can replace it in some cases.
• Production of complex shapes
• Fast production preparation
• Price of a prototype
• High accuracy
• The possibility of further processing components (machining, grinding, …)
Disadvantages of 3D printing
• Production of a part of the conventional methods has a greater accuracy
• Not suitable for mass production
• Verification of manufacturability
• Verification of assembly
• Design components
• Simulation of stress and flow
FDM method was developed and patented by Scott Crump in 1989.
The principle of the FDM melting thin wire (thermal plastic, metal, wax, etc.) in a heated nozzle which is moved by a stepper motor above the worktop. The material in the nozzle is heated to a temperature a few degrees higher than its melting point. The component is created on the board. After applying the desired layer which has a minimum thickness that depends on the type of 3D printers, the carrier plate is always reduced by the value of the layer.
• Wood + Polylactide polymer
• Sandstone + Polymer
• A large amount of useful materials
• Minimal waste
• Low cost of functional prototypes
• Its properties are printed components approaching final products
• Surface quality
