Print FASTER: Tuned Profiles or Drilled Nozzles?

Drilling out nozzles seems to be all the rage today - but does that actually get your prints done faster or are you better off cranking up speeds and accelerations in the slicer?

That LTT water bottle joke, man yoi got me

[Livingstonshoedios]

that LT Tea joke caught me off guard! got a genuine belly laugh!

[Spitfire]

That LTT reference is legendary ! :D
Also I think it would have been interesting to talk more about E3D V6 flow limitations. With my usual settings for a 0.6mm nozzle, 210°C, 0.3mm layer height and 0.7mm line width, you are limited to around 60-70mm/s. From my experience that's the sweet spot for a "fast but reasonnable" profile.
With a Volcano hotend, you sould be able to easily double that speed but you may be limited by other factors then, mainly cooling as shown in the video but also motion system for cheaper cartesian-prusa style printers, or even extruder if not dual-drive.

you must be kidding me. you bought a domain and redirected it to amazon "tea" search with your affiliate. LOL, your a legend :D

i could complain you didnt mark it as a affiliate link, but never mind xD

Nice tea store you have going on there Tom, hehe

I love how were moving backwards to early printing nozzles. Drilling out the nozzle from an acorn cap nut was the only way to get one back in the day

As a designer, I must say I am blown away by how the design of your shirt is reflecting the color scheme of your studio setup. Awesome!

First!
Also, here's a rough summary of my "03c" compromise profile for my MK3:

SPEEDS
Infill 250 mm/s
Perimeters 150 mm/s
External perimeters, small perimeters, top solid infill 80 mm/s

ACCELERATIONS
Infill, perimeters 4000 mm/s² (could probably still go higher)
External perimeters 1200 mm/s²

Z-hop reduced to 0.3 mm

Travel speed at 250 mm/s

Minimum layer time 10 s

Extrusion temperature 220° C

Use at your own risk 😉

I completely lost the thread on all the variations you tried without some sort of summary or graphic. Gotta see the data to make sense of

Great video. Seeing those speeds makes me even more happy with my railcore. I built it with a volcano, and use a 1.2mm nozzle. I print at 150mm/s and 9000mm/s² acceleration. I printed a bathroom trash can in less than 5 hours!

I am so glad you came back to do proper technical videos that are correct and true to their nature, very good level . love it

[StormBurnX]

I haven't used prusa slicer before but I do love that cura/creality slicer let you set the rates of inner and outer perimeters individually, so I have my external surface go half as fast as the internal walls and infill for example. Prints absolutely FLY and then when it hits that outer layer it slows down and really brings out the finer detail.

I love the gradient background light. Looks great on camera.

I have no doubt in my mind that someone at LTT watches your videos, probably Anthony or Alex. Bracing for a shoutout.

How to print faster in four easy steps:
-Establish the flowrate limit of your nozzle. 8-10mm3/s is a good starting point for a lot of hotends, if your cooling is up to that.
-Establish the print speed your kinematic system is comfortable with. Most systems can print at 45-60 without excessive ghosting.
-Divide flowrate by speed to get the square area your need to print at. In this case, 0.16-0.17 mm2.
-Pick a nozzle size and layer height accordingly, as small as you need to meet this but as large as you dare to lose resolution on the print. In this case, 0.6mm nozzle and 0.3mm layer height makes sense.
You can now print as fast as your printer will allow at the best resolution this point will offer.

Kind of surprised you didn't try a commercial large diameter nozzle, especially with the runout your drill bit had 😱

Thanks for the vid!

[ChriFux]

i'm personally a fan of the 0, 8 mm nozzle. clean 1mm walls, which is easy to consider when designing models

[tripy]

I laughed so hard at the slap to LTT at 5:00
Awesome !

[TS_Mind_Swept]

It's always funny to watch these videos and think of where 3D printing was just 3 years ago; definitely glad we've been able to make increases with Speed without having to drill out nozzles SoonerLater

[ZakLeek]

Great video Tom, I love these experiment videos and how well you explain them all!
