Stefan talks with Tom about his visit to TCT Formnext 2018. They discuss two recently released papers on potentially harmful emissions of 3D printers. They further debate if it is worth buying a cheap printer and then investing a lot of time on upgrading it or if it is more efficient to buy a decently working one right away. Finally, they answer viewer questions regarding grinding up plastic scraps for recycling and the usefulness of infinite z-belt printers.
Tom and Stefan talk about their experiences in annealing PLA prints and discuss the recent change in Fusion 360’s pricing model. Recently a paper on a so called “3D printer fingerpint” was released that claims to be able to track prints back the printer they were made on, with stunning accuracy, so they talk about how realistic this could be and what the implications of such a method might be. Tom recently came back home from his roadtrip all over Europe where he filmed bits for his RepRap documentary and talks about the new high temperature products he has seen at E3Ds headquarter. Finally Stefan recently built his DIY filament extruder and talks about his first experience in making his own filament at home.
Tom explains the drama that has been going on with MRRF 2019 and discusses with Stefan the advantages and disadvantages of bowden and direct extruders used in 3D printers. Tom also got himself a new FLIR thermal camera and talks about its applications in 3D printing. They finally discuss the question when FDM printing will become obsolete.
