Advanced 3D Printing Techniques: Designing, Modifying, And Improving Your 3D Prints

Please note: exam questions are subject to change.

1. The easiest 3D file to modify as it can be parametric and change to meet your needs is a/an JPEG file STL File Factory File Openscad File
2. The best 3D prints are a result of A very high extruder temperature Marinating the printer's constant temperature Printing quickly to avoid cooling Cleaning the filament
3. When food might come into contact with a 3D printed object you must Be sure to use a tight manifold design in able to sanitize the 3D object Use ABS filament as it is generally considered "food safe" Use PLA filament as it is generally considered "food safe" Not worry as all plastic is "food safe"
4. To create a CAD design that makes organic shapes and threads to attach to a water bottle the best option would be To use program that builds designs with "primitives" such as TinkerCAD or Openscad To use a macro-based program such as Design Tool Fusion 360 To design a blank smooth hole and tap (cut) threads into it To increase the extruder temperature for such fine printing
5. To produce a faster print and maintain quality you might have to Increase the printer speed Increase the extruder temperature Use a larger diameter filament Reorient the 3D object's axis orientation
6. To make a hole in a design with Openscad just Simply use the "hole" statement Simply use the "difference" statement Design the object around a round empty space to create the hole Just drill a hole into the finished printed object
7. The best placement of an exposed 3D printer would be In a closet On a rolling cart for easy mobility By a door to generate interest Under a ceiling vent to prevent overheating
8. To increase the strength of a 3D design Print at a slower rate Increase the extruder temperature for increased bonding Use ninjaflex filament Increase the infill percentage
9. To store most 3D filaments you should protect it from Moisture Light Heat Cold
10. To modify an STL file with fusion 360 You must change it into a factory file first You can copy your design and paste it over the part to be changed You have to change it into the mesh environment You can't change a STL file once it's rendered
