Revolution
Technology caught up with
imagination
, e.g. things are now cheap or off-the-shelf
3D printing
(
Additive Manufacture
)
Computer aided manufacture
(CAM)
Sliced
into
layers
Reconstructed
a layer at a time in the
printer
FDM
Printing
Made from
thermoplastics
like
PLA
and
PET
Plastics are
melted
and pushed through a
nozzle
in fine streams
Printer
moves in
XY
plane until a slice is done, then
2nd
axis
moves down an increment and new slice is printed
FDM Printing Methods

Printer

FDM Printing Pros
Printed on relatively
inexpensive
pieces
Consumable
is just the
filament rolls
Filament
rolls available from
wide selection
of sources
FDM Printing Cons
Lower/
poorer
resolution with rougher layers
Lower
bonding
force between layers
Easily
break
along layer lines
Resolution is based on
nozzle
size
