Extrusion problems

Videos that might interest you:

In this video, we will look at the different extrusions rate problems. You can have over extrusion and under extrusion or just the right amount.

So I will show you the look of something that is over extruded, correct extrusion and under extrusion. You will see an example of each. And how to recognize this problem.

Then I will demonstrate how to measure the extrusion rate of your 3D printer, with a simple technic, and a direct way to calculate the percentage of correction needed.

And finally a quick word on how to adjust the rate the easily.

Hi, I'm Frank my channel is all about 3D printing. I can't get enough of my 3D printer. I make everything and anything out of 3D filament (PLA, PETG and more). As I say a printer that is not printing is a missed opportunity.

I'll be doing electronics, mechanics, computer engineering, DIY, reviews and tutorials.

I update twice a week on Tuesday and Saturdays.

Where has this video been all my life, my printers been out of commission for nearly 6 months simply because nothing I tried worked I even replaced my entire print head, apparently my printer was having horrible horrible under extrusion with it only putting out 25% of what it was supposed to, fantastic video I’m surprised this never showed up when I searched my problems.

iam new to 3D printing, and i was surprised i got it perfect first try! it is not exactly "perfect perfect" but iam happy with it. soooo many ideas trapped in my mind for 2 years are prone to become true!

Cheers frank been having headaches over this blob issue for about a week now my flow rate in cura was 100% that was way over extruding infact i had to half it to 50% thanks for the help bud finally i can get back on to some nice models again

good quality video, but I think you could have given a little more information and demonstrated how you actually calibrated your machine. Now I have to go somewhere else to get the information that I need. I'm not trolling you but hope you accept this as helpful criticism so you can make more informative videos in the future. Respect

This is one of the best videos about extrusion out there! It's short, to the point, has examples and provides a solution. You got yourself a new subscriber!

First actually helpful video on correcting my under extrusion problem

[christophercola]

Thanks for making it a super short video! I hate it when channels make it 20 minutes long to explain something simple

[DustinBecker]

Quit, easy, to the point, and extremely useful

One quick problem I found with the instructions is that you can't use the difference to find the percentage for correction. At smaller numbers it will be relatively close, but quickly escalates. You should divide the amount you told it to extrude by the actual amount extruded. In your case 100/96 gives 104.166%. This isn't much difference, but at 90 out of 100 the error is 1% (111% vs. 110%), and 80 out of 100 the error is 5% (125% vs. 120%).

You my guy are my savior I was having quality problems on the anet a8 ( not the best printer I know but it’s my first one) and this fixed it

[sejlefrew]

thumbs'd up because you provided examples, just what i needed to pin down a problem

[isaackershnerART]

Thank you!

i just attempted this and found out i was 1cm short for every 10 cm! This could be related to a bigger issue with either the extruder or bowden system but this should help for now! just trying to keep my ender 3 pro alive for a little longer. got a direct drive CR10 and now I want another one :D

I don't have a 3D printer yet, but planning to get one soon. I will store this helpful bit of information away in the mental bank, I'm sure it will come in handy. Thank you.

Dude! I am a total newbie. You're not going to walk me through the calibration. C' on, Man!

[bluebikegarage]

Thanks for the quick instructions, helped me a lot!

[raptordragneel]

Nice now I need a 3D printer already have so many ideas

[matesinku]

Thnx Frank, for the quick explanation

what if my prints are perfect bottom or near perfect, with perfect sides but the top seems like its over extruding? like it has deep ripples in the top. could this be from the nozzle hitting the surface? sometimes when it goes from one end to the other it will almost drag a little over the surface and leave a line where it went. what could be the issue?

I'm a clueless bambu lab X1C owner....but I'm learning. (Maybe a "push & go" machine isn't the best way to learn).
What I got from this vid is what under/ over extrusion looks like! 👍
Thanks.🙏
My Lab printed 2 good prints, but now the extruder box keeps bashing the front door, (knocking the front cover off and telling me the cutter is stuck, but it isn't), laying shadow first layers in the corners or edge of the plate and over extruding.
All the self calibrations change nothing.
I've serviced the belts and now can try adjusting the flow rates in the right direction.
Fun nightmare.😳

Old video but thank you! Helped me out.
