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.

Selling our creations? & SLA Printer Lockdown

Stefan joins this Podcast from his holiday in South Tyrol. Topics are not only how to properly relax but they also cover a Stop-Motion Benchy animation, an update on the Chitubox lockdown of the Mars 3 firmware, an upside-down 3D printer, and a simple way of multicolor 3D printing. 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

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. The questions cover topics on how to make 3D prints watertight, Siraya Tech resin availability in Europe and RRF on other boards besides Duet.

Trademark, Re-branding & Filament Welding

In this episode, Stefan proudly presents the trademark certificate that he registered for his channel name and talks a bit about the process involved in applying for it. Tom discusses his plans on re-branding his channel. The following topics cover procedural G-Code generation and the FullControl GCode Designer. After that, Tom and Stefan briefly talk about a recent controversy surrounding Make Anythings Astrolabicon Design that popped up by another company on Kickstarter. Next, Tom introduces his plans for the VORON 2.4 Live build and talks about 3D printed solid-state batteries. Finally both answer questions on how to test the speed of a 3D printer in a review and what to do with filament leftovers.

Weird Printers & Good Bye Dragon Hotend

This episode is full of weird 3D printers, starting with a 3D printing simulation from Spee3D. Tom and Stefan further talk about a new dynamic build platform concept to reduce the support amount and a Japanese project that converts a 3D printer into a production line plus the Thermorph concept that allows automatically folding 3D prints using a smart combination of PLA and TPU. Then they discuss the morality of selling a community firmware as their own and that the popular Dragon Hotends that seems to be wiped from the market as a result of SliceEngineerings patent on it. The Q&A section covers the question of when slicers will finally support real CAD data in the form of STEP or IGES files.

Are we geniuses?

In this episode, Tom and Stefan present their new logo and talk about a semi open-source approach to electric driving vehicles, Lulzbot’s new “as low as $750” printer, Stratasys’ last heated build chamber finally expiring and a slicer integration to finally print 90° overhangs without support. The main topic is about the question if we are genii since so many reach out to us as their last hope for support and why we often have to refuse direct assistance. Questions cover “why PLA doesn’t get soft in hot tea water”.
