Support Magic: A Support Test for Mixed Materials

Change list: 10/8/23 round 2: Updated profile purge volumes and 3MF files. 10/8/23: Updated to v16, with a chamfer tweak to the model to aid testing, and fixed print profiles to be better. Multi-material systems are great for many things, but one of the most powerful things they can be used for is near-pefect supports, particularly with the popular PLA/PETG combination. Many people are scared to try this… and I want to help you succeed. Support Magic is a 3D model that has multiple different tests and is designed to be used with mixed-material supports. A typical example is the PLA/PETG combination, although many others are possible. Such “breakaway” supports offer typically excellent finish quality because of the dissimilar materials, and the fact that you can print with no Z-gap. Support Magic tests the quality of your support material setup between the two materials by testing the removal, durability, and surface finish of each section. Support Magic can help you achieve perfect sup
