Question

plz answer all of these multiply chiice question plz tahnk hurry

Which of the following statements about extrusion additive manufacturing is true? O Extrusion AM results in parts with anisotropic mechanical The strength of printed parts is highly correlated to layer thickness and infill density With decreasing layer thickness, surface quality improves All of the above

Answer 1

1) answer all of the above

yes all the options are correct

extrusion am results in anisotropic

strength of parts increases with increasing filling desity

and surface finish increases with decrease in thickness of layers

2) answer is mass manufacturing

because this shoe doesn't require and special features by the coustomer , just can be manufactured in large quantities

3) answer is filaments with standard diameter

remaining are not used in desktop Machine

4) coustamization of individual

thia is not a mass produced part, different people has different dimensions for the part ,so it comes under this category

5) answer is adaptive manufacturing

different models of aircraft require different design of the part so adaptive manufacturing is the best

6)answer is 4 th option

less strength of 3d printed parts are typically less than parts produced by convectional processes

7) answer is " thermoplastics"

thermosetting cant be used because they become harder with raise in temperature
