Traditional tooling Can be expensive Can be time consuming Vent holes Tedious Labor intensive Photo: Courtesy of Flickr KP Choo

6 FORTUS for Thermoforming
Alternative tool making process Reduces labor Reduces lead time Reduces cost FDM® process Industry leading Production-grade thermoplastics Extruded, deposited in layers

7 FDM Process

8 Applying Fortus Key items Benefits Additive process Materials
Build controls Benefits Simple 5 step process Materials for speed/tool life Process controls

9 Application Brief 50% 86% 29% 75% Consumer packaging CURRENT FORTUS
SAVINGS Lead Time 3 days 1.5 days 50% Labor Time 14 hours 2 hours 86% Total Cost $700 $500 29% Story: Machined tooling: prototype only so easy to machine material. But 1 man-day to drill vent holes (1 – 2 thousand for the multi-cavity tool) FDM: simple in and out Stress the labor savings. For some, reduction in labor is much more important that lead time (e.g. not enough people to get the job done). Also the reduction is much more impressive. labor rate $35 for Current method and $62 for FDM. Assumed more highly skilled labor for machine ops, etc. Note that the labor line (indented) represents the labor portion of the total listed in the row above. The story Time and money not biggest value. Process change was. Could be prototyping vacuum forming tool while part still being designed. Off the critical path! Also, maybe, add another embellishment….after prototyping, vapor smooth and prick surface to come up with beautiful marketing samples. (story from our most recent vapor smoothing guided) Labor Cost $490 $125 75%
