Why stuff breaks, Robot Arms & Home-Compostable PHA Filaments
Thanks to Private Internet Access for sponsoring this episode! Check them out at https://www.privateinternetaccess.com/TheMeltzone This episode starts with a discussion about the longevity of common 3D printing materials and why sometimes filament snaps on its own in the Bowden tube. Next, Tom and Stefan take a look at Formlabs' new FUSE 1+ 3D printer that claims to be able to do wasteless SLS printing, which would be an amazing step forward for that technology! Then there is a quick update on the BambuStudio source code that just was recently released. After that, Tom shares his interest in building a robot arm for filming, and 3D printing using DUET hardware and rambles about the ongoing E3D ObXidian teases that he's fed up with. Then they talk about an STL subscription service and if that's an alternative to buying files separately or by being a Patreon of designers. Finally, they have a talk about new PHA filaments that were just released to the market and claim to be really home-compostable.
I caught Covid at MRRF2022 & Slicing Revolution in CURA and PrusaSlicer
This episode is slightly different because Stefan records it straight from Covid isolation which he caught, as many others, at this year's Midwest Reprap Festival in Goshen, IN. After a short status check and some stories from MRRF, Tom and Stefan discuss the recent merger of Ultimaker and Makerbot and what this will mean for the two brands as well as Thingiverse. Staying on the topic of Ultimaker, both talk about CURAs new Arachne slicing engine that dynamically adjusts extrusion width for more detailed and denser parts. Since CURA is open source, Prusa also implemented that feature in their new 2.5 alpha version of Prusa Slicer. Talking about open source, Tom and Stefan discuss the recent issues of Bambulab and QIDI not releasing the source code of their modified PrusaSlicer and CURA builds. The final section covers the question of what happened to PlyBot?
Anker Make M5 & BCM3Ds novel resin printing method
their permission over the last years and how they want to change their business practice in the now. BCN3D formally known for their dual-head FDM machines are getting into the market of resin 3D printing but with a real twist, which will allow using higher performance resins and even multi-material printing. Prusa has done a lifecycle analysis of their new recycled materials they are offering and Tom and Stefan talk about "real" recycled 3D printing filaments from the German Start-Ups RecyclingFabrik and QiTech. Then there is an update on the Prusa XL which will stick to regular and open-source nozzles in stark contrast to E3Ds REVO. The last topic covers the just-started Kickstarter of the Anker make M5 and if it might be worth the $759 MSRP. In the question section, Martin asks if Copper would have advantages over a Brass volcano adapter.
Dream Studio, Macro Photography & Sneaky 3D Printing Quiz
alk about an advertised 3D printing quiz which they think is rather used to create classification data for an AI. In the questions section, Tom and Stefan discuss why most 3D printers use thermistors and not thermocouples.
Simplify3D V5 "confirmed" & REVO problems
substantial news is that Anker, the power bank and electronics accessories maker, will get into the 3D printer market and will launch their first machine on Kickstarter soon. Next, Tom and Stefan cover 3D printable accessories for a new Ford truck and the Steam Deck, for which Valve recently released the CAD files. Next Stefan talks about an issue he recently had with his E3D REVO review unit and Tom discusses his Form 3 review machine that turned out to be an unreleased Form 3+ which he didn't know about. Stefan quickly gives an update about the "killed" stepper driver. Questions cover 3D printer recommendations, especially pre-built core XY, and what happens to additives and pigments when you compost plastics.
Is "exposure" enough payment & German channel?
This episode starts with the question of whether content creators should have to license 3D printable models that others released under a non-commercial license or if the exposure alone is enough "payment". If you would license your creation how would you even do that? Then there are rumors that Anet, the infamous maker of the Anet A8 is gone from the market. Next Tom and Stefan talk about the recently announced date for ERRF and if they consider going. Stefan asks himself if he killed his first stepper driver and Tom explains how that even is possible. Stefan talks about his plans on launching a German channel and if this might be worth the effort. Staying on the topic of running a channel, both discuss if video sponsors are good or bad for creators and content. Questions cover adding a pattern into a nozzle and if PLA really biodegrades in a home compost.
Open Source CAD & Selling Stuff Online
experiences running an e-commerce business and what options for selling products online are. After that, they discuss the dangerous practice of smoothing FDM prints by spraying on printing resin. Printed Solid is yet becoming another company that switches to cardboard spools for their filaments and will also be contributing to the Foundation E3D will set up in Sanjay Mortimer's name who recently passed away. Fuslab claims that the recent community-developed Rolling Screw Extruder is infringing on their patent even though prior art was discussed and built years before they filed their patent. Staying on the topic of patents, both shortly talk about a high-flow hotend patent that E3D applied for. The questions cover topics on the compatibility of E3D Revo on the Prusa MK3 as well as converting an old Prusa printer into a CNC router and preheating filament for higher flow rates.
Prusa XL (obviously) & Creality MMU?!
This podcast episode covers the physics behind Stefans recently reviewed CHT nozzle and his DIY version of it. Both discuss the advantages and disadvantages of this design and how it compares to a Volcano hotend. Stefan briefly talks about how he got kicked from AMAZON with his threaded inserts. The big topic is the Prusa XL and its new, smart features. This new design includes an extrusion force sensor that another company is using to print fully dense FDM parts so Tom and Stefan analyze whether this might also be something that could be implemented on the Prusa. The last topic covers the CoPrint which is an MMU project that Creality seems to endorse, though also comes at a steep price tag. Questions cover a novel 3D laminating technique, the question of why thermal fuses are rarely used in 3D printers, and how much Tom and Stefan earn with this podcast.
Thingiverse Data Breach & Molten Prusa Heaterblock
Stefan talk about the recent Thingiverse Data Breach, how it was handled, and that this is just another nail in the coffin. This is followed by a discussion about Thingiverse alternatives and Prusa's plans of re-branding PrusaPrinters. On the topic of Prusa, they talk about a recent incident where a heater block of an original Prusa melted away and what the reasons might have been. Next, they switch to resin topics including a double vat Elegoo printer and a Rotating Vat machine for high-speed printing.
E3D Revo & Thingiverse Robs Creators
The first episode after the summer break covers E3Ds new Revo extrusion system and Prusa Automated Farm System that they are currently demonstrating in Dubai. Stefan quickly talks about his line-up of threaded inserts that he recently launched and Tom gives his impression about the SL1S Upgrade that he installed on a live stream. Both discuss a controversial topic because Thingiverse seems to be automatically replacing the affiliate links from creators with their own ones. The questions cover the hotend of the upside-down 3D printer that uses a 90° bent for compactness.

They discuss the question if they should start selling plans for their creations. Questions cover more information around the licensing of the STL to Solid conversion in Fusion360.
Stop Making Ender-3s & Über-Materials
clones with little to no innovation. After this ramble, they talk about an artistic lamp Kickstarter campaign that uses orange peel filament which unfortunately seems to be only questionable marketing. Though during their research they've still stumbled upon a way how orange peels might really be transformed into a polymer. Next, they discuss 3D printer modifications to soldering robots and pen plotters. There is a short section about a new tool in Fusion 360 that can convert stls into nice, solid bodies. Finally, they answer a question on why there is no über-material that satisfies all our 3D printing needs.
Recycle everything: 3D Prints, PET Bottles, Spools and Turbine Blades
Thanks to JLCPCB for sponsoring this episode! Get custom PCBs from $2 with free SMT assembly at https://jlcpcb.com/RHS This episode covers a ton of recycling topics starting from Stefan's adventures into 3D print recycling over the PETBOT that allows direct recycling of PET bottles, to the number of wasted plastics in filament spools all the way to reinforcing PLA with shredded turbine blades. Tom and Stefan further discuss MRRF that happened the weekend before the recording and ERRF that was canceled. At MRRF Lulzbot presented their new 3D printer model that starts at a quite steep price tag. Then there is some discussion on the recent Chitubox Pro launch where many fear that their MSLA printers might in the future only work if they subscribe to the service (UPDATE: https://twitter.com/UncleJessy4Real/status/1411765198730448899?s=19). Questions cover what printer or method might be suitable for highly accurate parts.
Mom, we're famous!, Ultrasonic resin heating & watertight 3D prints
Tom finished his VORON 2.4 build live streaming marathon and talks about his experience and the choices he made, for example using a DUET 3 with Reprap firmware instead of the usually used Klipper configuration. Stefan shows the latest Make magazine Germany in which this Podcast got featured. Both discuss the “Jugend Forscht” winning entry where ultrasonic modules are used to heat and disperse resin for better prints. Then there is a talk about the suspension of the Torshn Kickstarter and a still on-going crowd funding campaign on a 3D printed bike helmet.
