I tested how much the strength or better the layer adhesion of FDM 3D prints is affected by the amount of cooling air we use. By properly adjusting this value we can increase the strength of our parts by more than 50% and make them almost uniformly strong. I also scanned a couple of 3DBenchys printed at different fan speeds with my AtosCore from GOM to find out how cooling affects the accuracy of 3D prints. 💚 Support me 💚 Patreon: https://www.patreon.com/cnckitchen Join as a YouTube member!
