MORE ADVANTAGES OF A 3D MODELLING

AND QUESTIONS
V. Ryan © 2006
 

ADVANTAGES

1. Complete 3D models can be manufactured including those with hollow parts that could not possibly be made by hand in one piece, even by the most skilled engineer or craftsperson. Parts such as bearings, engineering parts and complex working models can be manufactured.
2. A variety of resins and waxes can be applied to the completed model. These increase the strength of the model, its temperature resistance and allows paint and finishes to be applied realistically.
3. A two part urethane can be added to the model to give it the properties of rubber.
4. Models can be electroplated to give the look and feel of a range of metals.
5. Prototyping machines such as the ZPrinter 310 can even be used to produce highly accurate patterns for casting.
6. Manufactured model parts can be combined with real parts to produce a fully functioning product that can then be tested and evaluated
   
 
   
QUESTIONS:
1. What are the advantages of making an accurate model of a prototype using a 3D printer?
2. Draw a simplified sequence drawing of the stages involved in making a prototype using a machine such as the Z310 3D printer (from Z-Corporation). Add notes to help explain each stage.
3. What is the meaning of the term C.A.D. ?
4. How does making a 3D model of a product help a design team develop the product?
5. Research 3D modelling machines using the internet. Collect information such as the cost of machines, where they are made and what they are capable of producing. Include pictures/photographs.
6. Do you think that sometimes there is no need to use an expensive piece of equipment such as a 3D printer to make a model? Explain your answer.
