Stolen YouTube Account & Printer Maintenance Jun 04, 2020

Show notes

After thinking about buying a lathe for ages, Stefan finally bought himself a new machining tool for the workshop. Tom shares his own experience with his Mini Lathe. Tom recently received a Prusa Mini and talks about his first impressions as well as some plans for it in his upcoming 3D Printing Beginners Series on YouTube. Both discuss the recent theft of fellow YouTuber Heliox’ channel and a new “Ultra Fast” printing process that slightly resembles an old CRT television as well as locally pre-heating a print for better layer adhesion. Miele released some printable upgrades for their appliances, so Tom and Stefan discuss the feasibility of these parts and what we could see in the future. Topic of the week is the maintenance of 3D printer – how much is necessary and what to regularly check? Questions cover automatic bed change and the applicability of a filament-width sensor.

Open-Source Metal 3D Printer, Nonplanar Nozzles and Tesla's Model Y using 3D Prints May 03, 2020

Show notes

Lots of interesting topics this time! Tesla is apparently using last-minute 3D printed parts in the first Model Ys they delivered; Adrian Bowyer is proposing a novel print removal system; and the US Army has been working on a non-homogeneous 3D printing filament.

But Stefan and Tom haven’t been idle, either and have been working on the Toolchanger and on finally getting an old CNC working. All that and more in this episode of The Meltzone Podcast!

Best practices for printing PPE and plans for our next CNCs! Apr 09, 2020

Show notes

It’s The Meltzone Lockdown edition! Tom is running out of home improvement store goods while Stefan is holding himself over with VR and finally building his E3D Toolchanger. We’re also talking about printing faceshields and other PPE and how getting organized is really important right now. Also, Makerbot is supposedly opening up their Method 3D printer to filaments from other manufacturers. In the questions, we cover filament diameter conversions, building a new printed CNC and Autodesk’s patent on non-planar slicing.

3D printed medical supplies & tons of questions Mar 25, 2020

Show notes

On this content packed episode, Tom and Stefan talk about their recent live streaming efforts, VR, the newly added FFF slicer in Fusion360 and why Stefan thinks it’s a challenge to add gears to his new plastics shredder. There are currently a lot of efforts being done to use 3D printing for medical equipment due to the current Corona pandemic. Both discuss the positive and negative sides of those and why there also can be a danger in printing medical supplies. There is a “new Thingiverse” but is it better than the old one? Tom and Stefan try to answer viewer/listener questions on high power lasers in SLA printers, the right material for 3D printed CNCs, if E3D really performs quality control, if Fusion360 might implement non-planar slicing, trouble with white filament, under-water curing and their favorite thread profiles for 3D printed parts.

Light Weight PLA & Teflon Lined VS Full Metal Hotend Jan 14, 2020

Show notes

Tom and Stefan are back from their holiday break and meet up in the “real” CNC Kitchen. They talk about current projects like Stefans work on Colorfabbs Light Weight PLA (LW-PLA). Both discuss the recent problems with the Hermera Extruder and how E3D is handling it. The topic of the week covers the differences between Teflon-lined hotends and full metal hotends, where the differences are and that the latter isn’t always the best choice. Questions cover the differences between PETG and ABS as well as printer advice and it’s better to buy a machine or to build one from scratch. At last both talk about the harmful fumes of additive manufacturing and how to pre-vent them.

Damaging Prusa's boards to flash firmware? Dec 19, 2019

Show notes

Is Prusa turning on the open-source community by requiring you to physically damaging the Mini’s board to run custom firmware? That’s our big topic of the week! Well, technically, topic of the bi-week? Stefan has been working on a surprisingly simple and universal variable infill algorithm while Tom has been trying to combine the advantages of filament and resin printing. In other new, Marlin 2.0 has finally come out of beta and the E3D “not a Hermes” has started shipping! We talk about our experiences with both of them. And we also got some good info from you all in the comments from the last episode – there’s lots of interest and some corrections on metal 3D printing.
