How to Make Your Own 3D Print Glue - The Perfect Solution for Broken Printer Parts

[@Dtr146]

Finally. I've been waiting for PLA gloop to get back in stock but all of these third-party sellers keep buying it in bulk loads and doubling the price. I'm going to order that solvent now and make some of my own.

[@MakoPCandNetworking]

I have been using the Plastic-welder stuff for years... started using it as a kid when I built plastic models. Love the idea of melting filament into it. Down side to it is, its exspensive, 13 bucks for each color you want to be able to glue. Might be able to make smaller batches. Pro tip, use q-tips as applicators, brushes are expensive and not really able to be cleaned.

[@MakoPCandNetworking]

I have had great luck with JB weld UV cured cement as well

[@DreadMakerRoberts]

The reason for the little jars is that I can make about 5 different glues with one bottle. I agree it is expensive but at the same time distributed properly it can last a long time

[@WBBlocker]

Seems like a great tip. Best ending of any video on KZbin 😂

[@TrenchcoatSteve]

0:52 Frank gives good glovin' but Ben gives great tips!

[@ZMan3k]

Sweet trick! Will definitely be trying this when I run outta gloop.

[@DreadMakerRoberts]

Awesome let us know how it compares when you do.

[@whitsheupto1981]

I generally print in PETG and have used Plast-I-Weld solvent in the past. I got it at Hobby Lobby. It’s super viscous and hard to apply a small amount, so making it into a glue would allow me to smear it on. Thanks for the tip!

[@DreadMakerRoberts]

You are most welcome! And yes I need to re-learn the name of the product LOL

[@mainstay.]

I've done this with styrene but never thought it would work with PLA. Thanks hugely

[@DreadMakerRoberts]

You are welcome!

[@afg122602]

I agree. I was surprised when he said pla.

[@MakerHacks]

In model making we call it Sprue Goo (recent term, back when I got into it we didn't have a catchy name we just called it melted plastic) and it is used for filling gaps, strong bonds, and even used for molding and crafting new bits :) There is a guy in the Warhammer community makes whole models out of discarded sprue, really neat stuff

[@DreadMakerRoberts]

Love getting stuff like this in the comments. Now I have new terms to search for and learn some new stuff. Thanks!

[@DreadMakerRoberts]

Now we need to come up with a cool name like that for the 3d printing folks. Filament Sludge? Nozzle Grunge? Plastic purge? What do you think?

[@MakerHacks]

@@DreadMakerRoberts Plastigoo? Spool Goo? :D

[@DreadMakerRoberts]

SpoolDrool :)

[@ratfink6670]

Thanks for the tip. Can acetone be used for melting the plastic? Also, when using the solvents, after the PLA or whatever material is used to make the glue....after applying it, how long will it take to cure?

[@Dtr146]

Ooh buddy I'm glad I always look up MSDS sheets. This stuff is super easy to make at home with just two chemicals and a mason jar. It's methylene chloride 80-90% and methyl ethyl ketone at 5-15%. Boom Mic drop

[@Dtr146]

For anybody wondering. I'm talking about the stuff he dissolved the plastic end. Plastruct

[@camibeans9622]

It worked I like commented and subscribed lol just say it. But keep it short and sweet like you already do! Thanks for the R&D love the videos doggy

[@MiguelRodriguez2010]

Great stuff, thanks!

Glad you liked it!

[@john_jacob_jingleheimerschmidt]

I've seen isopropanol used to smooth PLA, I wonder if maybe thats a less toxic alternative to the plaststrut

[@DreadMakerRoberts]

I have not had the chance to use that stuff. Could not hurt to try this and find out. Report back if you do and if it works well or not.

[@hughessay1372]

When filling a seam, put strips of masking tape on each side of the seam before adding your filler. That way you can scrape the excess away fast without sanding the surrounding surfaces.

[@DreadMakerRoberts]

OH! Great idea. Thank you

[@franksilva3566]

Would this work with PETG?

[@franksilva3566]

Can you use "Weld-On 3" as a solvent? Thanks

[@ravenspropshop]

Hey Ben! Chloe here! So for a solvent glue would weld-on 4 work? It’s what Odin used to glue styrene together, it is a solvent glue

[@DreadMakerRoberts]

Possibly. It is worth trying.

[@Mike-uo4xy]

What's the break down time of the pla? I started a jar 2 days ago and I can still see pieces of pla, like it's not breaking down

[@D4RKFiB3R]

Hi Ben, I'm finally getting around to making some WastePaste™. Do you know of a good alternative to Plastruct in the UK? Thanks :) ffs, it seems my comments keep getting removed. There will probably be a string of them tomorrow. Sorry about that lol.

[@DreadMakerRoberts]

The key ingredient in the plastic weld is methylene chloride. So go to a hobby shop or a place that sells plastics and see what thinners they have that have a large percentage of that in it.

[@D4RKFiB3R]

@@DreadMakerRoberts I bought some E.M.A Model Supplies Plastic Weld, from a local model shop. Like you said, this stuff works amazingly well 😃 Thanks.

[@DreadMakerRoberts]

@@D4RKFiB3R Awesome!

[@D4RKFiB3R]

@@DreadMakerRoberts Hi Ben, what is the best way to store this stuff, and how do you clean the brushes? Thanks.

[@techdiyer5290]

If you boil it what happens ? Edit: How would it affect the glue ? Maybe it makes it less toxic, or ... even stronger? Or juat ruins the glue...

[@DreadMakerRoberts]

Why would you boil it? How would you boil it? Regardless heating solvents before they gas’s off is something YOU SHOULD NOT DO!

[@techdiyer5290]

@@DreadMakerRoberts well, if you get rid of the water content, it's stronger because it's denser

[@techdiyer5290]

@@DreadMakerRoberts probably by putting all the jars in one big pot and filling it to where it's just above the glue level, but not high enough to get in the jars obviousily outside...

[@DreadMakerRoberts]

Still would not recommend this. Heat and solvents is not good. And the water content in this case is so very minor the gains, if any would be fractions of a percent

[@techdiyer5290]

This is probably where you could use a shredder on your rafts skirts brims failed prints and use them instead of new fillament! It's still technically plastic, so it works, heart me if you think it works ! What do you think ? This would probably work to smooth out those annoying layer lines for people who make models and stuff 😁

[@DreadMakerRoberts]

YES! all of this! 4 hours is the min dry time. I prefer overnight. So with layer lines and such this would need the 24 hour dry time to be sandable.

[@starfleet42]

How well does this work with something like Carbon Fiber filled PLA?

[@DreadMakerRoberts]

I do not know, but my bet is it would work well

[@Declopse]

Any chance for plastic weld alternatives? I'm located in Europe. Edit: Plastic Weld 57 ml bottle Expotools glue PW located in the UK. Would this work too?

[@DreadMakerRoberts]

The key ingredient in the plastic weld is methylene chloride. So go to a hobby shop or a place that sells plastics and see what thinners they have that have a large percentage of that in it.

[@squishybrain]

Would MEK (or an analog) work as well?

[@DreadMakerRoberts]

Very likely. The plaststrut solvent is mostly mek

[@Francois_L_7933]

Looks like it's really sticky. Sad thing is that those plastic weld type products are really hard to find in my province... and maybe in all of Canada. And when I can find something, it's usually quite expensive.

[@DreadMakerRoberts]

I’m in Calgary. Not as hard as you think. Where are you at? Maybe I can help out

[@techdiyer5290]

Try online

[@soyguikai]

Is this like 3d gloop?

[@DreadMakerRoberts]

yup

[@Baldavier]

@@DreadMakerRobertsBut 3d gloop dries quicker, so might they use a different solvent? :/

[@baldrickhornby9646]

Once made how long is the shelf life

[@DreadMakerRoberts]

It really depends on how well the container is sealed. Couple weeks easy, with the right container months/

@@DreadMakerRoberts Thank you

[@BenRyherd]

Just FYI it's Plastruct not Plastastrut

Sigh... Yes you are correct. When I made the link for it in the description, I realized that literally for like 40 years I have been calling it that incorrectly. LOL. Also too lazy to re-shoot anything so I get to eat humble pie on this one.

Drama Queen, yes, the smell is prominent. You DO NOT need a respirator for a few ounces of Methyl Ethyl Keton, Methylene Chloride You could allow the entire bottle to evaporate in a two bedroom home and my sniffer would even cause an alarm If you were to allow it to evaporate in a small bathroom, you might pass out if you didn't have a fan Anyone who took this personally. I just can't stand drama queens. Brother, one of my vids I neutralized sulfuric acid no hood, no respirator just gloves at the sink with a face shield that was dangerous, this is childsplay compared to sulfur gas I could see a 5 gallon or 55 gallon drum gassing off but a few ounces 😂🤣😂 Laugh my ass off! Note: This technique has been used since the 80s for industrial repair of plastic parts no longer in production. Example, machine cover, component box etc 90s kids used it building their models

[@8BitLife69]

So basically what those of us printing with ABS have known for over 10 years. Solvent and filament. Ground breaking stuff Ben.

[@DreadMakerRoberts]

I need to find a decent TPU solvent now

[@KieranShort]

Yes ABS & acetone had been known for eons, but I haven't seen a chemical weld for PLA before.

[@tokagehideto]

"With ABS"

[@MakerHacks]

First, not everyone knows about it - especially as fewer people use ABS nowadays than we did back in the day - so someone will be happy to hear about this, and second Ben didn't use ABS in the video. I will check out your channel to see what groundbreaking stuff you share, judging by your comment it should be absolutely amazing stuff! ;)
