3D Chameleon, PLA or PETG?, Running a Print Farm and MORE!!!

This Episodes Questions:

Hello,
I’m a dedicated listener of your podcast and I have a question that’s been on my mind regarding 3D printing materials. Nowadays, PETG is available at a price point similar to PLA, sparking a debate among enthusiasts. Many argue that PETG is superior in every aspect, rendering the use of PLA obsolete. However, my personal experiments, corroborated by various online sources, indicate that PLA exhibits greater tensile strength and, in some cases, enhanced impact resistance—especially PLA+. This does seem to vary across different brands.
While PETG undoubtedly outperforms in terms of temperature resilience and chemical stability, its reputed strength superiority is something I find quite perplexing. My theory is that PETG’s significant deformation under gradual stress, as opposed to PLA’s sudden failure under higher loads, might be influencing this common perception. I would love to hear your thoughts on this topic. Thank you for the consistently excellent content! Kelly

Hey guys love what you do, I’m listening to the “Worn Nozzle” Podcast. You mention the 3D Chameleon multi filament changer. You guys should try to get him on the show, https://www.3dchameleon.com/ . The inventor is Bill Steele (I may have misspelled the last name) and if you will look at the dates of releases, Bill’s invention predates all the multi filament changers even Prusa’s MMU, Bambu’s AMS, etc. He is up to version MK4 and this unit is amazing. Don’t dismiss it as a gimmick, it works better than all these others out there including the new “enraged rabbit carrot feeder”. Chris

Delta Voron?, Organic Supports, Wet Filament and MORE!!!

This Episodes Questions:

Hi everyone,
I am jeroen pattyn from belgium and im a 3D print hobbyist for 2 years now .
Is there a possibility to use 2 different kinds of support on 1 model ?
Sometimes i m thinking to use organics on one overhang and raster on the other . This for saving some time and getting better results .
I was thinking first i could do this with the paint on supports in prusaslicer but i dont find a possibility .
I have a prusa xl 5 head printer and a bambulab x1 CARBON i would like to hear your thoughts on this one guys .
Greetings from belgium and keep doing the fun job with the podcast .

Listening to the most recent podcast discussing volumetric flow rate. If you weren’t aware, this can be displayed in cura. Once the model is sliced in the preview tab, there’s a drop down where you can select options other than line type. One of these is flow, and it will show a color gradient on the model of what the volumetric flow rate is at different regions of the print. This can be used to see the max vol flow value too. Cheers! Ben

I’ve been 3D printing for about 8-months. I currently have a Bambu Labs X1C. I’ve never dried filament. I had the last meter or so of a roll of PLA get brittle and I just recycled it, but no other issues. I mainly print with PLA and PETG. I store them in sealed plastic cereal boxes with desiccant. They hygrometers in the boxes typically read ~10%. I keep fresh desiccant in the AMS, and the humidity meter in the slicer is typically under 3 our of 5. The social boards are filled with wars over “to dry, or not to dry”. Can you give us the true skinny on this topic?
Two questions on filament drying: 1) Under what conditions do you dry filament? What types, and how do you know they need drying? 2) If you dry filament, what do you use. I know the X1C can dry, so I already have one option. I’ve seen people use food dehydrators. And then there are special purpose filament dryers. Thoughts and recommendations would be appreciated.
Love your podcast! Paul

Filament Issues, Toxic Fumes, Which Beginner Printer? and MORE!!!

This Episodes Questions:

Hello!
I’m new to the 3d printing world (one week) and have enjoyed learning from your podcast.
How do you recommend diagnosing and fixing printing issues with different filaments?
So far Ive only run PLA and PLA+ through the Bambu x1C – I’ve got some TPU, Silk and ABS coming so it’d be good to be prepared for when someting eventually goes wrong! Norman

I recently decided that I needed more printers, as one does, and building one was fun, so of course I need a Voron 2.4 350mm. Now, I could just use the Print-it-Forward and buy the pieces, but I wanted to print it myself. I built the frame, added the panels, and by moving the MK4 screen a bit, I managed to use the Voron-frame to enclose my MK4 so it could print ABS better. I don’t have the greatest ventilation available, but there is some, and I don’t notice very much smell. Is modern, quality ABS a bit better health-wise, or is it still kinda bad? I don’t sleep in the same room Christian

My son, age 13, wants to buy a printer. His budget is $350 MAX. We have been doing lots of research in this budget range via YouTube, podcast and talking to people.
We have been leaning towards the Ender 3 ke or the A1 mini, since the Prusa is just too far out of our budget right now.
The usage would be for masks, small to medium size mechanical parts designing, mechanic tool box organization, speed is NOT priority (but nice to have), print quality is preferred.
I want to know, now that some of these printers have been on the market for a little while, what would you recommend for a first time buyer today, considering the whole market and not just these two mentioned.
Thank you David
