How to remove ooze strings from your 3d Prints
Вставка
- Опубліковано 17 жов 2024
- Have you ever 3d printed a nearly perfect part only to have it ruined by oozing and stringing? Here is a quick fix using a heat gun to melt away the ooze quickly and easily. It is practically magic...
Oozing in general can have many causes. If you trust your slicer settings and you suddenly ran into issues it might be worth trying to dry your filament.
You many want to build a dry box or just be sure to store your filament in sealed containers if you live in an area with high humidity.

I saw this video... Blew my mind, so simple. But, you can't hold the heat to the PLA too long, or too close, you gets the melt, and drooping.. Great Flick, Haas man!
Good call! I got a food dehydrator and use it on all my filaments.. It has made improvements in all materials, especially nylon and ABS based.
Was a bit skeptical about the method at first, but man does it work. Awesome video.
Excellent and thanks!
For small pieces I use a blow dryer and move it very quickly. It can easily warp otherwise.
Like the other gent stated, I am SO THANKFUL for this tip! I am a subscriber now too!!
Excellent! Thanks!
First time 3D printer, also in Ohio and know what the humidity does to my tools. Thanks for the info on here, gonna print myself one of those boxes!
The problem with the heat gun is it heats up all the filament and the stringing has to go somewhere? it turns into little plastic balls the makes your print rough.
Sounds like your stringing is pretty severe. In the cases I've used it the strings are much finer and the balls are much finer/smaller and not visible like in the video. If the strings are much bigger try adjusting retraction, drying the filament or if it's a flexible filament that does not respond to retraction try setting the travel moves to stay inside the part so all stringing is inside the infill (there are good tutorials on this online). Good luck!
Strings are always caused by moisture contend in the filament.. I've had several brand new rolls, just opened, and I get strings... I'm still looking for the right answer.
I wouldn't say all strings are caused my moisture. Retraction settings are how you control stringing typically. But assuming your retraction settings we're good for a filament one time and then after while they aren't ok it's likely moisture that's now causing the strings.
Filament can be wet right from the factory, and different filaments can have different "viscosty" in liquid form, so they may need different retract settings, and you PTFE tube fitting (if ur printer is bowden setting) can become worse overtime and lost the ability to hold the tube tightly, which will, again, lead to stringing
Interesting... I wonder how moisture in the filament affects the strength of the finished part?
Most of the moisture evaporates but in plastics like nylon I think that is a good factor to think about
I would like to see a follow up print of the same part with the same PLA after you dry it to see how much difference it makes.
+vitriolix I will get a short video about the food dehydrator info out this weekend. It worked great by the way. Check out my Instagram for a photo of the before and and after drying.
Small Butane torch with a quick pass will do a much better job without deformation of the surrounding areas 👍
Ffffff*ck man, you saved my life with this 4 years old comment. I have to clean strings for more than 1.000 pieces and heat gun was not working for me. I owe you many beers, thank you! Greetings from Madrid.
Was looking to see if someone had experience with this. Might need to pick up a torch tomorrow.
I store my 1kg and smaller spools in gallon freezer Ziploc bags with a few desiccant packets tossed in. The bags are cheap, they're air tight and desiccant packets are also cheap online and if you spend a couple bucks more you can buy ones you can dry in the oven and re-use.
Brand new to printing and today just had some minor strings on an Eiffel Tower build with petg. Gonna give this a try but almost certain it will take care of the issue. Thank you in advance!
i quickly hover a lighter under mine to remove the strings. does no damage to the print and melts the strings away instantly.
3 months on this issues tried everything changed every pieces ... Still have oozing... Help 😢
Very good video and fantastic information. Thanks! You gained yourself a subscriber 😃
+iGameOver Thanks!
I was using a soldering iron to just run over them all - but this looks much cleaner :)
I just used a hairdryer. Works well. Thx for the inspiration :D
Was it on the highest setting
I have a relatively dry air in my room... Will a PLA filament soak in that moisture for about a month sitting on the table? I'm getting more strings now and started to think... can it be something else than retraction settings?
It's possible. Could try switching filaments to a new box. Try running old code on print that had less strings see if it now is more stringy. Or try drying the filament and see if the strings go away
Unfortunatelly I have only new PETG filaments. As soon as I'll finish my dry box (only fittings left probably) I'll be testing these PETG.
For the old PLA I'll cut off 10-20m of the filament and try to dry it in our Hotter airgrill. Didn't tried yet so need to be careful :)
If you have a heat gun with two settings, which setting works best, low heat or high heat?
Try low heat first. If it's taking too long try high heat but be careful as your part may not take high heat for long without warping.
Safety Glasses Required OK, I just tried both. High heat worked better. It melted off the strings in about half a second before the bulk plastic really got warm. At low heat I had to hold it for longer (1-2 sec.) to melt the strings, by which time the bulk plastic started to soften a bit as well.
Would a hair dryer do the job?
Haven't tried it but probably. Just needs to get hot enough to melt plastic.
I'm too poor to afford any kind of dehumidifier, I hope that 3d printed one can be made with moisturized filament.... since it's all i got atm. then i can dry it in that, then use the dry filament to make a proper one and then use that. ha!
Does this work with a hair dryer?
Depends if the hair dryer gets hot enough. Never tried but it might.
I tried used soldering iron and lol it melted silver on my print

Why is he printing directly onto the heatbed
I'm not...the Prusa i3 mk2 originally shipped without magnetic flex beds. The PEI sheet simply attached to the bed.
An almost 6 minute video and you take 4 minutes to mention the solution. Such a waste of time!
What temperature are you using
210 for PLA.
does this work for ABS as well?
Yep works with any fdm 3d printed part/material.
You could also use a plastic bag
To everyone seeing this and asking if a hair dryer will work. Not with PLA. You need alot of heat and quickly. At least the same temp you print at, if not hotter. 200 c is about 400 f. Hair dryers dont get that hot. So you're more at risk to softening the 3d print and deforming it. An open flame, run over small pieces quickly also works. You do risk leaving singe marks though but if you plan on painting it anyway then a camp lighter is a cheap way of doing it.
This is why theory's are nice, but putting them into practice is better. I just tested this and a hairdryer definitely WILL work. Since the stringing is soo thin, and heat does get sufficiently hot to melt it away slightly. Though admittedly, it doesn't do as good a job as a heat gun would but it gets you 90% of the way there. Also, I'm using PLA+ which I believe has a slightly higher melting point so who knows, it might work even better on PLA parts.
I used a lighter.... But I'll try a heat gun next time
Thank you so much for this
why are safety glasses required for this.
thank you!
Two things to minimize stringing. (1) An appropriate amount of retraction. It will be different for each filament type. Also retraction will not be the complete solution. (2) Use coasting with a good slicer like Cura 3 or Simplify3D. The right combination of both techniques will greatly reduce stringing. The whole purpose is to reduce the pressure on the filament in the extruder before and during the extruder movement.
+Digital Ed may be it wasn't clear in the video but with the same gcode/settings(that normally doesnt string) you can get stringing if the filament has absorbed moisture. Which is what happened in my case and I didn't want to reprint the part. To avoid filament absorbing moisture it should be stored in a sealed container with dessicant. If it does get wet you can dry it with heat in a food dehydrator or oven.
All of my rolls of fiber are in Ziploc bags, each with desiccant, stored in airtight containers. I have never had a problem with moisture. I would still emphasize the feature of coasting is as important as retraction to minimize stringing. I have only seen one online contributor that has covered it (Maker's Muse).
I encourage you to watch my video "How To: Dehydrate 3d printer filament". In that video I use the exact same Gcode (retraction and coast settings as well) to print the same part with no stringing at all. The only difference was drying the PLA filament in a food dehydrator for 12 hours. No doubt if you do not have your retraction and coast settings dialed in you can still have problems but in my case it was simply wet filament.
Aren't you supposed to wear safety glasses? Like, aren't they required?
dude you live in ohio? :O You should come to Cincinnati we have all sorts of maker stuff here. in the tri county area we have a really neat workshop. in downtown we have a few smaller maker spaces and the library has a semi crafter space of sorts!
I do live in Ohio. Not that close to Cincinnati though but it sounds like I should come check out the maker scene there sometime. Does Cincinnati have a Maker Faire ?
@@SafetyGlassesRequired uh no but there are a few maker spaces popping up. Also the library has a maker space, one in a few library's in the nation who do actually
@@SafetyGlassesRequired update: yes there is a maker fare for one day. Its april 19th? If you google cincinnati maker fare there is a link for one on bing at least. I just looked it up
Awesome! I'll have to keep that in mind and put it on my schedule.
NA miata!!! Brother!!!
dip in acetone problem solved. hair dryer not the way buddy
I've acetone vapor bathed parts as well. It tends to melt fine details and something as fine as the part shown in this video would have collapsed. Also acetone is can be used as a solvent for ABS but the part in this video is PLA and acetone wouldn't have done anthing. Watch the video to completion it's a heat gun and worked very well to post process stringing caused by "wet" filament.
