9 Frequently asked questions 9.1 Smart Wipe Tower size and additional print time How big is the smart wipe tower? Wipe tower is always 60 mm wide and contain between one and three 15 mm slots based on the model you are printing. If you only two materials are printed at one layer, one slot is used. - Page 16 Smart wipe tower prevents the need to use any sort of ooze shields as in traditional multi extruder systems! The size also remains constant, no matter how many copies of the objects you print or how big the object is.
- Page 17 We suggest to print more copies of the same object, if printing small parts as the Smart Wipe Tower will remain the same size.
