7 Families of Additive Manufacturing Form

What is the 7 families of additive manufacturing?

The seven families of additive manufacturing encompass a range of technologies that create objects layer by layer from digital models. These processes include:

• Material Extrusion: This method involves extruding thermoplastic materials through a nozzle to build parts.
• Vat Photopolymerization: In this process, liquid resin is cured layer by layer using ultraviolet light.
• Powder Bed Fusion: This technique uses a laser or electron beam to fuse powdered material into solid parts.
• Binder Jetting: A binding agent is selectively deposited onto a powder bed to create a solid part.
• Material Jetting: This process involves depositing droplets of material to create layers of an object.
• Sheet Lamination: Layers of material sheets are bonded together through adhesive or ultrasonic welding.
• Directed Energy Deposition: This method uses focused thermal energy to fuse materials as they are deposited.

How to use the 7 families of additive manufacturing

Utilizing the seven families of additive manufacturing requires understanding the specific applications and materials suited for each process. Here are some steps to consider:

• Identify the desired properties of the final product, such as strength, flexibility, or heat resistance.
• Choose the appropriate additive manufacturing process based on the material and design requirements.
• Create a digital model using computer-aided design (CAD) software that meets the specifications for the chosen process.
• Prepare the printer settings, including layer thickness, print speed, and material feed rate.
• Monitor the printing process to ensure quality and accuracy throughout the build.
