Getting the Most from Cura: Presented by Steve Cox
Ultimaker's Open-Source software Cura is an amazing free slicer for your 3D models. 'Quick print' is great when you're doing your first prints but delving into the software in more detail can save you from waste material on failed prints and over-use of infill, wasting time using supports and failed prints generally.
Steve's Webinar is an informative look into Cura and how you can use it to save time and money.
