- Explore the truth behind 3D printing speeds in our latest video, where we dive deep into the realities of slicer settings and filament capabilities. Many believe that setting their 3D printer to 300mm/s or purchasing 600mm/s filament can drastically reduce printing times. But, is this feasible? I unravel the impact of printing speed, acceleration, and how they influence your 3D printing efficiency. Discover if high-speed filament is the solution to cutting your print times in half, and learn essential tips for optimizing your printer's performance.

The point of "high speed" filament is that it retains layer adhesion at higher flow rates. Polymaker defines it as filament that has at least 80% of normal layer adhesion at 24mm³/s extrusion rate. You can print any PLA at high speeds, it will just result in lower strength. Two things to keep in mind: 1) it doesn't matter unless you're actually pushing high flow rates 2) many brands are labeling standard PLA as high speed.
would love to see a comparison between the overture TPU high speed and standard. TPU is not really covered by alot so I think the vid would do well
I actually use both their TPU and Highspeed TPU! The high speed stuff definitely makes a difference, as the print speed for normal TPU is quite slow. I’ll think about putting a comparison video out on that.
@@PrintPractical Thank you! I have been using their standard TPU with a 2.4mm3/s volumetric flow rate and 30mm/s on 0.2mm walls. Hoping the high speed stuff can do better without sacrificing quality. What pressure advance k value are you getting? I can't tell the difference between 0-0.1 k value haha. Printing fine with k=0.02 and 1.03 flow ratio. Cheers
I've been using 3d printers for a good while. I see my speed top off after the bottom layer is done and it stays that way till the end where at the last 3 to 6 layers it slows. So this doesn't apply to all printers. Most new printers, print like mine with very little down time on speed accept for complicated prints.
Great video! Clears up some misinformation
Great analysis of the real factors that limit printing speed. I do wonder if you combine the high-speed filament with high flow ObXidian nozzle what type of performance you can get out of the X1?
Never heard of that nozzle but just looked it up. Definitely would probably help with the keeping up with the flow required for faster printing. I wouldn’t run into issues under extruding at higher speeds like we saw in the video. Though once again, the main limitation of the printer is the max toolhead speed (500mm/s P1S) and max acceleration (20000mm/s^2 P1S).
Another thing to note is that at the higher acceleration settings, the amount of vibrations/shaking that occurs during printing is significant. I know the Bambu printers have some compensation algorithms built into the firmware, but who knows what the limits of that is. This could also affect print quality.
I have the ObXidian nozzle and Elegoo Rapid PLA. Its my worst performing volumetric flow PLA in my stock. I used IIID Max for 40 volumetric flow easily at 220-225c. Not only does it underextrude when pushed fast, it's also very stringy. IIID, Bambu and Sunlu don't string and keep up with each other in the 35-40 volumetric bracket without high heat.
As for layer adhesion, I have no issues with PLA. PETG is the opposite story with the ObXidian nozzle, which I believe it won't really benefit from the flow or speed because then it just pulls apart.
@flat_stickproductions209 what speed settings / acceleration settings are you using?
@@PrintPractical standard speed and acceleration profiles, with volumetric flow controlling each speed when sliced. 350mm/s 0.2 layer and 0.5 line requires a lot of flow.
It probably is just a flow rate number. If your machine can pull and push 50mm of filament instead of say a prusa mk 3 at 10-12mm and adjusting the heat up does NOT keep up with the flow. At that time you may need a Higher Flow material.
To me its more about wear and tear on the printer than saving a few minutes. That acceleration and deceleration cant be good for a printer, belts and bearings.
I removed a 0 from all standard travel and acceleration settings in hopes of making my printer last longer trouble free.
There's really no need to baby the printer like this. All the parts you mentioned are cheap, commodity parts that are trivial to replace.
@@donoteatmikezila Downtime may not be cheap due to loss of revenue or parts not being available to replace a down printer when parts do wear out due to being ran wide open nonstop.
Good luck!
