Tough Pro PLA+, Metallic Gold, 2.85mm

You can anneal your design after 3D printing for even better heat resistance and impact toughness.One of the big questions we often get about Tough Pro PLA+ is about heat resistance, especially in a scenario like a hot car.You can gain the maximum heat resistance by annealing your 3D print (furthest print from camera), but that's not always practical or feasible to do, especially as the part shrinks 1-2% during the annealing process and needs to be tightly constrained in a gypsum or salt flour to reduce warping.But, even without annealing, you can see that the Tough Pro PLA+ part resists heat much better than the Standard PLA+ (nearest to the camera). In some ways, in this test, the Tough Pro PLA+ part (middle part) is partially annealing in the temperature ramp-up. This is why customers state that it can work great even in a hot car in the desert of Arizona!
