Answer 1

wasting - drilling
additive manufacture - 3d printing
forming - vacuum forming / forging
finishing - painting
shaping - injection moulding / sand casting
joining -MIG / MAG welding

Question 2

properties of materials
Mechanical and others

Answer 2

strength, flexibility, ductility, elasticity, hardness
cost, thermal conductor, density, corrosion resistant, sustainability

Question 3

what is the difference between pure metals and alloys?

Answer 3

pure metals - made of one element, iron, gold, brass, aluminium
alloys - made of 2 + elements, must contain at least one metal element, much stronger and better properties than pure metals, stainless steel, low carbon steel, mild carbon steel

Question 4

what is a ferrous metal + examples vs non-ferrous metals + examples

Answer 4

ferrous = a material that contains iron
stainless steel, low carbon steel, mild carbon steel
non-ferrous = a material that does not contain iron
aluminium, brass, carbon, copper

Question 5

thermosetting and thermoforming polymers + examples

Answer 5

thermosetting = once formed they can NOT be remoulded and shaped
epoxy resin, urea formaldehyde, polyester resin
thermoforming = once formed they CAN be remoulded and shaped
acrylic, ABS, polylactic acid, polycarbonate

Question 6

polymers definition + examples

Answer 6

repeating chains of molecules
acrylic, ABS, polylactic acid, polycarbonate, epoxy resin, urea formaldehyde, polyester resin
