3D Printing Assessment

3D Printers is what type of manufacturing process

• Additive

• Subtractive

• Neither

Answer explanation

3D Printing is an additive manufacturing process as material is added one at a time.

Subtractive is when material is cut out to make the part we need.

The material that is used to print 3D objects

• Extruder

• Nozzle

• Filament

• Print bed

3D prints are printed from bottom to top, one layer at a time

• True

• False

Having a temperature that is too high for our filament can cause

• Warping

• Over Extrusion

• Under Extrusion

• Overhang

______ is needed when we have bridges or overhangs

• Enclosure

• Support

• Rafts

• None of the listed

The Orientation of how we print a part can affect our prints by

• Affects how fast our prints could be

• Could be changed to save how much Material is used

• Can make our prints stronger

• None of the following

We can improve our prints strength by

• Changing material used

• lower the % of infill

• change the orientation

• changing the temperature

Increasing the infill can improve the strength and increase the speed of our 3d print

• True

• False

the most effective ways to reduce warping are

• using an enclosure

• using a raft

• using a heated bed

• using support

A 3D Design file can be printed by converting to what type of file to print in a 3D Printer

• .PDF

• .F3D

• .CAD

• .STL
