4.4 additive Flashcards
additive manufacturing techniques
man. techniques in which materials need to be added to create the product
list additive techniques
paper based rapid prototyping
LOM
SLA
FDM
paper based rapid prototyping
layers of paper cut and glued together to create a 3d shape
LOM
3d product out of thin layers of polymer which are joined together
LOM adv and disadv
doesnt need support structures
high manufacturing speeds
poor surface finish
SLA
thin liquid resin layer solidified with a laser
SLA adv and disadv
quick
can be machined
cost of material can be expensive
high cost of machine
FDM
filament is heated in a nozzle and then extruded out of it layer by layer.
FDM adv and disadv
cost effective
wide material variety
iterations easily possible
limited surface finish
slow production speed for large volumes
dimensional accuracy
