In additive manufacturing, the different heat sources used can have limited

lifetimes. When the lifetime of such element is relatively short, it incurs high

losses in the form of wasted builds and reduced yield. In order to reduce these

losses, there may be contingency plans, or “backup printmodes”, that enter into

effect when such a heat source is lost (e.g. a heating lamp burns out).

Printmodes used as backup will typically incur extra costs per layer due to

tradeoffs by design, therefore one should minimize their use as possible, based on

cost optimization. This document describes a method to determine if, for a

particular job, it is worthwhile to the job until the end (starting from the moment

that the heat source is lost).
