Thermwood recently completed a 3D printed multi-piece foundry pattern. The pattern was printed on an LSAM 1020, and machined on a Thermwood 5 Axis Model 90 (because of other projects that were pending on the LSAM).
The pattern was printed out of ABS (20% carbon fiber fill). Print time for the project was 6 hours and 40 minutes, and the trim time was a little over 47 hours with multiple fixture setups.
