2 – marks question and answers
1. What is tooling in additive manufacturing?
Creating molds, dies, and tooling: Using additive manufacturing (AM) techniques to produce complex
tooling geometries and structures.
2. When was additive manufacturing developed?
- 1960s: Photo polymerization and early 3D printing concepts emerged.
- 1980s: First commercial 3D printing technologies, such as Stereo lithography (SLA), were developed.
3. What is the AM process?
Additive Manufacturing (AM) has been defined as the process of joining materials to make parts from a 3-
dimensional model data one layer at a time.
4. What are two advantages of additive manufacturing?
Advantages
, - Complex geometries: AM enables creation of intricate designs.
- Reduced material waste: Additive process reduces material usage.
- Increased design freedom: AM allows for innovative designs.
- Faster prototyping: Rapid creation of prototypes.
- Customization: AM enables creation of customized products.
5. What is virtual prototyping in additive manufacturing?
Virtual prototyping is defined as a computer simulation of a physical product that allows for designing,
measurements, data analysis, and validation, while offering advantages such as reduced cost and time, and
increased quality and productivity.
6. What is meant by rapid tooling?
Rapid tooling (RT) is a manufacturing method that uses rapid prototyping (RP) techniques to quickly
create molds, dies, or other tooling needed for producing parts. It's divided into direct and indirect
methods, with direct processes creating the tool itself from a 3D CAD model and indirect processes using a
3D-printed pattern to create a traditional mold. RT significantly reduces manufacturing time and costs
compared to traditional tooling methods, making it ideal for prototyping and low to medium-volume
production runs.
7. What are the classifications of rapid tooling?
Rapid Tooling Classifications
Based on Tooling Application
- Soft tooling: For low-volume production or prototyping.
- Hard tooling: For high-volume production.
, Based on Production Volume
- Bridge tooling: For medium-volume production.
- Production tooling: For high-volume, long-term production.
Based on Manufacturing Process
- Direct tooling: Creating tooling directly using AM or other methods.
- Indirect tooling: Creating tooling using a master pattern or model.
Other Classifications
- Disposable tooling: For single-use or limited production.
- Reusable tooling: For multiple production runs.
8. List the Characteristics of additive manufacturing.
- Additive process: Material is added, not subtracted.
- Layered construction: Objects are built layer by layer.
- Digitally driven: AM processes are controlled by digital 3D models.
9. Write the need of additive manufacturing.
The need for additive manufacturing (AM) stems from its ability to enable complex designs, create
customized products, reduce waste, and speed up production times, which leads to lower costs, reduced
environmental impact, and enhanced supply chain flexibility compared to traditional manufacturing
methods. AM provides greater design freedom, allows for the consolidation of multiple parts into a single
complex component, and facilitates on-demand production of both prototypes and functional parts. This
makes it ideal for industries requiring rapid innovation, high levels of customization, or the efficient
production of intricate, high-performance components.
10. Mention the impact of additive manufacturing.
Additive manufacturing (AM) significantly impacts product development by accelerating innovation
, through rapid prototyping, enabling greater design freedom for complex geometries, and creating
customized, on-demand products. This leads to shorter time-to-market, reduced material waste, and lower
costs by minimizing tooling, inventory, and transportation needs. AM also facilitates more agile
development, allowing for iterative design and quicker response to market needs, though challenges in
scalability and quality remain.
