Tom and Stefan talk about their travel plans to MRRF 2019. Tom explains how he’s getting back into PCB design and what techniques can be used to manufacture them. They discuss the differences between stepper motors and servo motors and if 3D printers could become better if they used servo motors.They also speak about if 3D printing is making the world a better place or if it’s only creating more waste. Finally they answer viewer questions on 3D printing education, materials for car parts and their video editing software of choice.
It’s the first episode of 2019! Along with a 3D printing wishlist for 2019, Tom and Stefan discuss their current capabilities of driving in the snow and moan about doing taxes. But also, about whether printing ABS still makes sense in today’s landscape of advanced materials, their plans for MRRF 2019 and what 3D printers and 3D printing projects they’ve been working on!

Stefan talks about his upcoming project on paste extrusion and his latest Dremel 3D45 printer he’s testing. He discusses with Tom the “Makerbot Method” and what could make it different from other currently available 3D printers. Furthermore they argue weather PLA or PETG is their material of choice and what the advantages and disadvantages of both are. Finally they both talk about their year as a YouTube creator and what they think is going on with platform at the moment.
In this episode, we discuss the proposal to use “virtual fibers” to strengthen FDM 3D printed parts that work by adding tiny holes to your model! We also go through whether you actually need to buy a slicer or if the free and open-source ones are now just as good – and finally, Tom twist’s Stefan’s brain with continuous belt 3D printers and why they can’t use a vertical Z-axis.

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.
