3D Printing Question and answers


Fill in the blanks
a.     The sketches in Extrusion and Ring Shape Generators are created based on curves that can be controlled by Bezier handles.
b.    Number of teeth and Pitch angle are properties of the gear shape.
c.     You can create new custom shapes using the Codeblocks programming language.
d.    To create a Voronoi pattern through a solid object, you need to cross it with the object and make the Voronoi tile into a __________.
e.     In design and machining, a rounded corner or edge of an objectis called Chamfers
Answer the following questions
a.     What is the advantage of using Shape Generators?  Name any three useful shapes.
Shape generator is a component in Tinker cad that contains custom shapes that are designed (using JavaScript code)
Some examples of shapes: Ring, Voronoi , Metric gear, ISO metric thread ,Image Generator,etc

b.    What is the significance of 1x, 2x, 3x while creating a brick model?
1x size creates a simple model requiring less number of bricks whilethe3xsizecreatesa complex one requiring a considerably large number of bricks
c.     Explain the advantage of using live collaboration in Tinkercad.
·        Tinker cad provides the Sharing feature through which a group of people can work on the same design in real time thus allowing collaboration projects.
·        A change made by any user will be reflected in the original design and all users will be able to view it.



d.    Which shape would you use for creating a base for an object created using the Ring shape?
Cylinder base is use for creating a base for an object created using the ring shape.
e.     How can you create a MetaFillet object from other basic shapes?
·        Add a box. Add a MetaFillet shape
·        Make the radius of curvature to the desired value.
·        Adjust the height of MetaFillet to slightly more than the box
·        Duplicate this MetaFillet androtate orflip and align it with the next edge.
·        Select all four MetaFillets and convert them to Hole
·        Group all objects to get the final shape.

1.     Tinker cad provides us with some basic shapes such as box, cylinder, sphere, etc., that we can use to design complex objects.
2.     Ring shape generators basically show a sketch with option to control the height and diameter along with the Bezier handles.
3.     Explain stair shape generators?
Ans: stair shape generators are used for creating a stair case. It take bunch of rectangles and make them in to the stair case by grouping them .
4.     Which short cut key is used to duplicate the object
Ans :Ctrl + D is used to  make a object duplicate.
5.     Shape generators are a great way to find what you want for your design.
6.     a chamfer is a sloped or angled corner or edge, and a fillet is a rounded corner or edge (true or false)
Ans : true
7.     Explain camfer ?
Ans : a chamfer is a sloped or angled corner or edge, and a fillet is a rounded corner or edge. These edges can be located on eitherthe interior or the exterior of a part.
8.     Codeblocks is a new beta addition to Tinkercad.
9.     Startersare examples of 3-D designs created using code blocks.
10.                        Which editor allows a group of codeblocks to be dragged to the trash can?
11.                        The code block editor allows a group of code blocks to be dragged to the trash can.
