Elaine,
At OPW we produce a number of prototype and pre-production sand castings
from SLA master patterns. 10-20 different casting designs per year on
average.
Turn around for castings from our production foundries varies, but is
typically 7-14 days depending on the complexity of the part, our project
needs and number of castings required. Quantities from SLA tooling vary from
1-250.
Casting size ranges from 1-2 ounces (>1 cubic inch) to 10+ pounds/casting.
We have prototyped sand castings in Iron, Steel, Aluminum, Zinc, Zinc/Alum,
and Bronze and plan to continue to do so.
We are actively seeking an RP process that will allow the creation of "Lost
Foam" casting patterns directly without tooling.
Any ideas?
Larry

Subject: metal castings
I was wondering what is the largest and smallest size castings made using
RP? Time they took from design to castings? Anyone doing anything new in
this area or is it becoming a dead issue?
