How is acceleration measured in "k" related to acceleration in g? Oh, and what is filament flow rate in cubes? No, really, this is a little passive agressive, but units are really important, they transfere so much information in a standard format. The information is often redundant, which maz be the reason why people use incorrect or incomplete units. But even if it is redundant with the context. The unit is the standard format.

That's not how input shaping works. It just splits the accelleration or decelleration part of the move into segments where every segment cancels out the previous segments resonance frequency basically.

Not only is this a true testament to amazing speed and quality 3d benchy printing. It is also a testament to the power needle that is registering all that nom nom.

Make the nozzle also movable in corexy gantry but reversed direction to the table, and you could divide the movement distance and acceleration by half retaining the print time.
@casaxtreme2952 12 сағат бұрын
That's actually not such a bad idea. Of course you can't move the print head so fast but every improvement counts. And since he already mentioned that halving the print time does not mean double the acceleration but rather some exponential increase in acceleration this might drastically reduce the max acceleration needed to get the print done. Perhaps it is worth thinking about how you could minimize the dynamic mass of the print head (for example only move the bare minimum of a nozzle with required heating / cooling and merge the filament on a stationary part of the print head. I know, talking is easier than actually doing it but I am so interested and would also love to work on figuring out the best solution, maybe that's the German engineer inside of me 😂 The next step (thinking outside the box) would be to habe more than one print head that can at least move in X/Y fast enough to both follow different print paths on the part simultaniously without collising. This is probably an insane programming challenge but might reduce print time by 30% (since some of the part can definetly not be printed simultaniously).

Maybe you could add glass skates to the build plate mount to remove some resistance. Also, Switching to 2.85mm filament may also help, it would certainly take some of the stress put on the extruders.

Can you modify the gcode. So that when it makes columns for roof, it does change the order / sequence. Now all of them bend same way, maybe it could help if the gforces on every layer would cat different ways, instead one, what hipotetically results in bended pillars. You are doing great job man!

@coledavidson5630 2 күн бұрын
At an uneducated glance, the extrusion rate still seems poorly uncontrolled. It keeps pushing filament out long after the print ends, like there's a lot of pressure built up, almost like you're hitting a physical limit in terms of fluid mechanics of how fast plastic can possibly flow out of the tiny nozzle opening? So there's tons of built up pressure that can't go anywhere and causes extrusion when there shouldn't be. However, judging by the results you're getting maybe this isn't a huge deal even if true

why are all those speedrunners using pla?
@ltsky311 2 күн бұрын
I like the design, but parts flying around at those speeds will never be stable. I'm not sure that will be able to surpass that of a delta printer in speed over a large part. I print 8 minute benchy's now with a non optimized file on my FLSUN S1 Pro, i might bump up the speeds to see how fast I can do it to some level close the the finished print you have just out of curiosity. However that being said, this could be a great idea for a laser or even a CNC router style design, it kind of reminds me of a maslow cnc. But that being said, I really do like the design. earned my sub just to watch your progress....

try fdm on micro silicon wafer scale ;) try fdm metal 3d printing too. the glass scraping noise. yep. well dont run at resonances, mix it up wide band. what do you think an air plane will do if it starts to resonate. the resonance is only the worst case scenario, normal x-y movement should not resonate much.
@DanFrederiksen 2 күн бұрын
very nice. how about high speed macro video to show the viscosity behavior of the plastic? if it's too sticky, maybe some kind of ultrasound to break viscosity. Maybe even only ultrasound without heating. Also what about direct magnetic drive of the build plate? light sandwich build plate with say 4 small strong neodym magnets and coils above and below each one. Throw it around like Chris Brown and Rihanna. Another possibility is a rotating axis fixed speed and a single linear movement which could be magnetic. So draw the benchy as polar. That's slightly cheating since it fits the shape a little but would be less direction change. Also you could do multiple point extrusion. With enough print heads like an inkjet printer you could imagine it's very fast despite calm motion.

At 20:00, I think the reason you get higher vibrational readings is that the resonating string was in some way bleeding energy out of the system, and dampening the string makes that energy find its way back to the build platform. Maybe having off-board resonating elements could even be a good thing? 😅

7:50 I believe you're right about it being resonance causing the sound. You could try to touch up the surface with a marker and see if grinding it again causes even removal of the marker to verify that it is not caused be an uneven plane.

"Look, grandma crocheted a benchy!" 😅 Sorry, I couldn't resist. There is for sure a great progress from the first benchies to the last. The greatest limiting factor is for sure the material that just doesn't harden fast enough. Also the inertia forces and thus possibly swinging of the suspended bed.

how about running coil tubes like a condenser coil run your air through the tubed coil while having the coil in a bucket of dry ice or liquid Nitrogen??? honestly think your air flow is to high being aimed in one direction you can tell it's blowing your extruded Filament around way to much!!! also maybe you can redesign the air ducts so they are around the nozzle but off set a little so it turns the air at the nozzle rather then blowing it to one side, it would be good to get it where the extruded filament is being pushed straight down by causing a cyclone effect

Imprssive! For the cooling: As you are aiming at the extremes and obviously not shying away from unorthodox solutions... I think water vapor cooling is a good next step. But you could try liquid nitrogen cooling as a further escalation to avoid any deformation after extrusion.

It seems like the asymmetric cooling could be solved by extending the air nozzle ring to 360° so it's blowing evenly from all sides. This would also keep it from blowing the part of the table because the air streams would cancel each other out. It almost seems too obvious. Is there's something I'm missing for why this wouldn't work?
