Sorry folks. I just rewatched the video and noticed I was saying "grams per cubic centimeter" when I should have been saying "grams per cubic meter". Let me know if you catch any other mistakes. DrVax
SYSTEMS OF MEASURE: "Units of measure" for the Metric System (SI) include as "base units" the meter (m), kilogram (kg), & second (s): mks. For convenience, in some cases, the units used are centimeter (cm), gram (g), & second (s): cgs. FILAMENT: Filament density is typically given in g/cm^3. So, I believe you were appropriate in the use of the language - though I have not thoroughly reviewed the video to confirm it was applied consistently throughout. CALCULATIONS: Any units can be used (even mixing systems). Certain choices will make calculations simpler, though, as well as less error prone. The important thing is to apply conversion factors as/if needed, and to use unit analysis to ensure correctness of calculations.
This is super valuable information. I was almost ready to pull the trigger on a 32 bit mainboard upgrade with pins for a runout sensor. You Sir just saved me over $100. Thank you! I subscribed.
Great topic. I use a large postal scale to estimate remaining filament. I offer a few cautions: The 1kg assumption is influenced by the honesty of suppliers & loading tolerances. A constant 250g spool assumption can be significantly influenced by spool style; since some have large side windows, vs none; plus spool material varies. I have had very heavy & very light spools. I suggest folks log weight & save one empty spool type, as a reference for future Filament purchases from each favorite vendors.
Well you answered the question I had about how to know if you have enough filament. That is a good idea to mark the weight of the reel. Thanks for sharing this.
Thank-you this was extremely helpful, I want to get into making figurines with the Ender 3 v2, and I've been playing with the CURA slicer to get a good idea on how to use it before my printer, and filament shows up. So far I think I have a good idea now, and I can't wait. I just need to get some extra equipment to sand, and paint my models afterwards
Thanks for the comment. P.S. I have started a new discussion forum at forum.drvax.com where we can all have more elaborate discussions and share pictures on our prints and printers. Check it out.
Thanks, that's a magnifficient trick to weight all rolls when full! (as long as you can rely on manufacturer provided filament weight being correct, not sure if low end cheapos can have a bit inflated values or not)
Hi Sir great video .. thanks for explanation. Btw is it possibile to ‘refill’ a new filament during the printing session? The printer will auto stop or continue moving without filaments (so the projects is gone) or we have to pause it before the old filament ends? Thank you
Great video, I’ll make sure to get a scale. BTW... it looks like your looking off to the right vs. straight at us or the lens. Possibly watching yourself on a flip out screen? Really enjoy your videos... thanks for sharing this tip/trick.
Great video!! I had been thinking along the same lines, but you have done great research and have it all put together. I have ordered the scale from your link in Amazon. I really like your idea about weighing each spool as you first use it. I'm curious how accurate the numbers are in CURA, I know the times are always off.
some confusion between area and volume; you're calculating cross sectional area, which multiplied by length of the cylinder gives you volume. Volume times density gives you weight.
Always weigh your filament when you receive it, Recently I have had some very under weight reels from eBay. Advertised as 1Kg net of filament but the whole reel only weighed 825 grams, yes a real rip off.
Hello🤝 Thank you for your video👍 Can I print different filaments on the same part? Example start with PLA, then TPU, then TRANSPARENT etc.. Is this possible? Thank you👍
It is even easier to use an empty spool instead of a full one. Zero the weighing scale with the empty spool on it, and after that you get the filament weight of the spool in use.
About End-Of-Filament sensor: I have a Monoprice Ultimate 2 printer and was wondering how to continue a print after the filament runs out? Seems to me there will be a gap.
Normally printer keeps track of it's current position. So when you get run out of filament, press "Pause" button or get electricity malfunction it will be able to remember where it was prio the events and will be able to continue (depending on make and model of the printer that you have).

You just need to start the scale with an empty spool on it (same kind of spool), then replace the empty spool with the spool of filament you using and the scale will show how much filament you have.

Another great video Doc! I would have never thought to do a video like this but you did, and it will be helpful to people.
Thanks

Great trick if u dont have a filament sensor. Didn't know most spools were 250g, that's great
Thanks for your very informative show. Now I don’t have to babysit my filament spool and your calculator is awesome. 👍👍

Material safety data sheets are very useful for many things around the house, especially for tinker-ers.
Yep. I agree.
Thank you, thank you, thank you! This has been a question I've wondered about! I can't thank you enough!

You are correct. Thanks for clarifying for everyone.

great video! i could’ve used this info before running out of pla mid-print lol
Fantastic. Superb. Thanks.
It is even easier to use an empty spool instead of a full one. Zero the weighing scale with the empty spool on it, and after that you get the filament weight of the spool in use.
But Dr. Vax, I like algebra. Oh boy, this is great advice. Thank you very much.
Thanks.
where do you get stl files for flowers that you have on your desk
OctoPrint has a plug in to say how much filament left

I've seen someone use a load cell on the spool holder
I weighed two empty spools; one weighed 218g and the other weighed only 178g.
Yep. That is why it is best to record the eight of the spool new with filament. Total manufacturers change spool construction.

You are correct. If you have an empty spool.
