Additive Manufacturing Basics

What is additive manufacturing?

• Additive manufacturing involves melting material to create objects

• Additive manufacturing is a process of creating three-dimensional objects by adding material layer by layer based on a digital model.

• Additive manufacturing is a manual process without the use of digital models

• Additive manufacturing is a subtractive process of creating two-dimensional objects

What are the advantages of additive manufacturing?

• Less durable products, higher production costs, limited material choices, reduced precision

• Reduced material waste, increased design flexibility, faster prototyping, customization capabilities

Name one common additive manufacturing process.

• Laser cutting

• Injection molding

• 3D printing

• Casting

How does additive manufacturing differ from traditional manufacturing?

• Additive manufacturing builds objects layer by layer using digital 3D design data, while traditional manufacturing typically involves subtractive processes like cutting or molding.

• Traditional manufacturing uses digital 3D design data for production.

• Additive manufacturing involves subtractive processes like cutting or molding.

• Additive manufacturing is slower and less precise than traditional manufacturing.

What are the key components required for additive manufacturing?

• 3D scanner, software, metal powder

• 3D model data, material, 3D printer

• CAD software, CNC machine, wood material

• Blueprint, laser cutter, plastic filament

Explain the concept of layer-by-layer construction in additive manufacturing.

• Layer-by-layer construction skips certain layers to speed up the manufacturing process

• Layer-by-layer construction in additive manufacturing is the method of creating objects by adding material layer by layer until the final object is produced.

• Layer-by-layer construction is a method used only in subtractive manufacturing

• Layer-by-layer construction involves removing material from the object in layers

What materials can be used in additive manufacturing?

• Wood, glass, rubber

• Alloys, alloys, alloys

• Plastics, metals, ceramics, and composites

• Concrete, paper, fabric

What are some applications of additive manufacturing in various industries?

• Agriculture sector

• Textile industry

• Food industry

• Some applications of additive manufacturing in various industries include aerospace, healthcare, automotive, and consumer goods.

What is the role of CAD software in additive manufacturing?

• CAD software is used to design 3D models that are converted into instructions for additive manufacturing machines.

• CAD software is used for creating 2D drawings only.

• CAD software is not compatible with additive manufacturing machines.

• CAD software is used for subtractive manufacturing processes.

Discuss the importance of post-processing in additive manufacturing.

• Post-processing only adds cost without any benefits

• Post-processing in additive manufacturing is essential for enhancing surface finish, accuracy, and mechanical properties of printed parts.

• Post-processing can be skipped to save time

• Post-processing is not necessary in additive manufacturing
