  1. I have been asked to give an hour lecture on 3D printing, how it works and it's applications. Can anyone recommend any good videos or resources I could use in this lecture? It will be delivered to students who have never used 3D printing before. Any suggestions would be greatly appreciated
  2. I have recently started using the Ultimaker 3 and the PVA filament and I'm having issues with its water solubility. I have printed twice using it and put one in cold water and one in warm water but neither seem to be full dissolving. The most part of the support either dissolves or gets tacky enough to peel off but the last bits attached to the PLA just don't want to come off. Is there a trick to this?
  3. I am looking at printing an object using a 0.8mm, 0.6mm and 0.4mm nozzle but I don't know what settings need to be changed accordingly. I have seen that the smaller the nozzle the lower the temperature and speed needs to be but nowhere gives any actual numbers. Is there anything out there which gives optimal settings in Cura for the different nozzle sizes?
