Introduction to Additive Manufacturing

What is additive manufacturing?

• A method of manufacturing using subtractive techniques.

• A technique for creating objects without any digital input.

• A process that only uses metal materials for production.

• Additive manufacturing is a process of creating objects layer by layer from digital models.

Name one common material used in FDM 3D printing.

• PLA

• Steel

• Aluminium

• Clay

What is the main difference between additive and subtractive manufacturing?

• Additive manufacturing is faster than subtractive manufacturing.

• Additive manufacturing adds material; subtractive manufacturing removes material.

• Both processes involve the same techniques and materials.

• Additive manufacturing removes material; subtractive manufacturing adds material.

What does FDM stand for in 3D printing?

• Fused Deposition Modeling

• Fused Design Method

• Fast Digital Modeling

• Fluid Dynamics Mechanism

Which technology uses a laser to fuse powdered material?

• Stereolithography (SLA)

• Fused Deposition Modeling (FDM)

• Selective Laser Sintering (SLS)

• Electron Beam Melting (EBM)

What is the purpose of a support structure in 3D printing?

• To provide stability and support for overhangs and complex geometries during printing.

• To enhance the color of the printed object.

• To create a smoother surface finish.

• To reduce the overall printing time.

Name one application of additive manufacturing in healthcare.

• 3D printed food

• Virtual reality training simulations

• Standardized surgical tools

• Customized prosthetics

What is the role of a slicer in 3D printing?

• The role of a slicer in 3D printing is to convert 3D models into G-code for the printer.

• To manage the printer's hardware components.

• To provide a user interface for the printer.

• To create 3D models from scratch.

What is the typical layer thickness range for 3D printing?

• 0.1 mm to 0.3 mm

• 5 mm to 10 mm

• 15 mm to 25 mm

• Any value as per our choice

How does additive manufacturing contribute to sustainability?

• Additive manufacturing has no impact on sustainability.

• Additive manufacturing contributes to sustainability by minimizing material waste, reducing transportation emissions, and enhancing energy efficiency.

• It relies heavily on traditional transportation methods.

• Additive manufacturing increases material waste and energy consumption.
