If you have ever wondered how much PLA, PETG, ASA, PA, and PET print strength are affected by the part cooling, here is the new video:

Results are very surprising! 😎
Small sneak peek of PLA results!

After many prints and tests, I finally have the detailed answer to a very important question. 🙃
Also, my brain is cooked after this... week... of testing...
These parts look almost fake as they turned out that good! 😎
Printed on my Voron 2.4 with a 0.5mm nozzle using Sunlu PA12-CF, with outer walls printed first.
Used 5 walls and 50% infill, so some warping was hard to avoid. Good thing that didn’t impact the design.
It still blows my mind how big this badge feels in my hands, but looks so small inside a huge 3D printer... 😂
It was CNC machined from aluminum by @pcbwayofficial.bsky.social 👍
Surely, you wouldn't be printing an even bigger 3D printer on an already massive one, right?
600x600mm Fysetc Venture XL video out!

The size of this Thing is INSANE!!! 🙃
But is it good or just another big 3D printer plagued with many issues? Watch the video!
Plus it had a bowden extruder and not direct drive 😂
Yes
Man... I remember the days of struggle with PETG on the dusty Mega S as my first 3D printer and having 0 experience. 😂
Who said PETG is hard to print? Just fully dry it and tune retractions. This is with a 0.6mm nozzle BTW.
With 60C chamber temps, steppers can easily reach 75-80C and above, depending on how hard you run them. Now, mount them on PETG parts that are not even rated for that temp under a light load, and apply the high tension of the motion system. Now that is a recipe for failure. :)
90C is ~15C higher temp than most PETGs are rated. It should do this. 😁
Maybe this will visually better show why you never print Voron parts from PETG...
I kept both parts for 5min in the Sunlu E2 Dryer at 90 °C.
The PETG part becomes like TPU, and the ABS part is still perfectly stiff with no deformation.
You think the linear rail reassembly is hard?
Well, it is a piece of cake compared to reassembling the ballscrew... 🥲🥲🥲
Fysetc Venture XL + Phaetus Rapido 2 UHF upgrade. Printing Sunlu regular PETG (0.6mm nozzle at 0.3mm layer height).
So... This was ~0.7kg print... and it wasn't even that big. 3kg spools are the norm here. But the variety of them and air-tight dry boxes are so limited. 🥲
Yeah, it will be interesting to see. Worst case scenario, I may even do some modifications on it... ;D
Nooooo, haha. It is only the hotend without the fan. :)
This is probably the most unconventional hotend design that I have seen so far... The Mellow NF FluxHeat hotend.
35mm length meltzone (the longest from all my tested hotends) and standard V6 nozzles.
Do you think it could outperform any of the current TOP 3 hotends? 🧐
Surely for a 600x600mm heatbed (4x beds), the 0.17mm range is good enough...
I could probably squeeze to 0.15mm, but that would be just a waste of time with no real benefit. 🤓
You can never have too many heatbeds... wait what!??

Testing these hotends by layer adhesion and extrusion force:
- Slice Engineer Mako
- MicroSwiss FlowTech
- Phaetus Conch M6
- 3Dc Starlex DHB
- E3D HF ObXidian
Thanks to all the companies that participated in this testing!
When people say Venture XL is big, IT IS BIG!
Even the photos don't relay the actual size... It is ridiculous!
This thing is never leaving this place, even if someone tried to steal it. 😂
Here are the first extrusion force results (220°C PLA). Stock Bambu Lab hotend vs E3D HF ObXidian.
Same length melt zone. Regular vs CHT design. I don't know how this E3D hotend still manages to keep amazing me... 🤯

Does layer adhesion correlate with the required extrusion force? 🧐
I have some nice and interesting hotends to test:
SliceEngineer Mako™
MicroSwissLLC FlowTech™
phaetus3D Conch V6
Swiss3Dc Starlex DHB
🙃
That's why I wish it existed as I could test it. :)
I assume we both have Orca slicer in mind, so you can do it in the printer settings: fan speed up and kick start times.
Yeah, but I am talking about the variable one, like with overhang print speeds (picture). I want lower overhangs to have lower fan speed that gradually increases the higher the overhangs. :)
If we have variable print speed for overhangs, wouldn't it also make sense to have variable print cooling fan speed?
It should be easy to implement, as it is the opposite of the print speed, no? I would love this for filaments like ABS, PA, for the best strength and the look.
I can't believe I only now thought of this... 🤦♂️
You can pack so much more desiccant into the AMS unit if you also put desiccant into the middle of the spools.
I used this model (but there are a lot of them): makerworld.com/en/models/12...
Pretty cool update. I know what I will be doing today... 😅
Correct, but it needs so much more for at least a chance to work.
