The chance that an abstract CAD model of a
plastic part assembly
will be perfect the first time is virtually zero.
WinTech Design recommends that a Stereo
Lithography Apparatus (SLA) prototype be made of all new plastic designs. SLA's can then be assembled
and checked for form, fit and function before ordering plastic injection
WinTech coordinates directly with the
SLA vendor (such as Solid Concepts, Inc., https://www.solidconcepts.com
). SLA models
typically cost from $80 to $500 depending on size and can be made in
high resolution or high strength materials.
