Design for additive manufacturing: DfAM basics

1. 1The statement “To design for AM, engineers trained for conventional manufacturing need to alter their design philosophy” is:

   1. AA. Only true if metallic parts are to be 3D printed
   2. BB. Valid only if polymer-based composite materials are to be 3D printed
   3. CC. Entirely true for all 3D printing technologies
   4. DD. Not valid for parts to be 3D printed from ceramic materials
2. 2The images given below represent (a) “supported” and (b) “unsupported” walls in AM design, for 3D printing using SLA method, the supported wall’s thickness needs to be at least

   

   1. AA. Half the thickness of the unsupported wall
   2. BB. Twice the thickness of the unsupported wall
   3. CC. Same as the thickness of the unsupported wall
   4. DD. It is not possible to use “unsupported” wall strategy in an SLA method
3. 3Overhangs in AM design generally require support structures in order to make their printing possible. This statement is:

   1. AA.True for some AM technologies
   2. BB. True for all AM technologies
   3. CC. True only if the material being printed is a polymer
   4. DD. Not true for any AM technology
4. 4The smallest feature on a part design was determined to be 0.2 mm. Which of the following AM technologies can print this design detail?

   1. AA. SLA
   2. BB. FFF
   3. CC. LOM
   4. DD. EBM
5. 5The images left show a part design in its non-optimized and optimized form. What kind of optimization was conducted on this part?

   

   1. AA. Bearing optimization
   2. BB. Tribology optimization
   3. CC. Embedded optimization
   4. DD. Topology optimization
