Everyone uses a hot glue gun to explain 3D printing, yet nobody sells hot melt glue filament for a real 3D printer! I wanted to change that and make the first hot melt glue filament, for the giggles but also to 3D print iron-on patches! Let's find out more!

@kira07 Місяць тому
why dont you find lower melting point TPU for the sticky side , and then use TPC on the top which melts in slightly highertenps , alterntively there are shoe glues that are flexible after cure, but they smell strong that you can paint on the other side. or maybe press the hot glue into a thin sheets , then cut to size with a plotter maybe ?

Hi Stephen, maybe you might have better luck with higher temp rated hot melt glues. The glues I use at work have a more yellow hue to them versus the crystal clear ones you're using. They melt at a higher temperature but solidify significantly faster. They might be harder as well. We even buy it pelletized as well as in large diameter sticks. You should have no problem finding pelletized hot melt if you ask around industrial suppliers, it's very commonly used.
@gedr7664 Місяць тому
for this application i think you need the different melting point for the bottom layer (~150) and top layer ~(200) - otherwise you would melt the patch and get rid of detail

The only thing I'd change about this process is ironing the patches from the fabric side, so more of the heat goes to fabric then hot melt glue THEN tpu, rather than hitting the TPU first. In my experience (with normal patches!) this helps them adhere better because the fabric is heated up to match the glue.

I do service work at a factory that makes glue sticks, they use a horizontal screw extruder with a 1" nozzle where it gets melted then it gets pulled through a 50ft water bed by a puller belt on the other end. They are indeed coated in oil to prevent them from sticking to the puller belt when they are chopped down into individual sticks.

@brianmi40 Місяць тому
@@jonasniesner At those temps have to keep it away from any clothes dryer tho. "PCL filament is a type of 3D printing filament made from a biodegradable and bio-based polymer called polycaprolactone (PCL). PCL is a good choice for beginners and kids because of its low-temp and safety. It is also eco-friendly, food-safe, and non-toxic. PCL has a density of around 1.2 g/cm3 and has exceptional mechanical properties. It melts around 60°C making it a safe thermoplastic to print and has a glass transition temperature of -60°C making the product extremely flexible and tough."
@SianaGearz Місяць тому
So a few months ago Lost in Tech showcased a filament made from PCL (polycaprolone) which melts at low temperature and might very well bind other polymers to textile. PCL pellets are also very easily and readily available in small and medium quantities e.g. as a crafting material, mould making material, temporary tooth filling.

You could build a large extruder to feed the sticks directly into a long conical nozzle to get to normal filament size. Should be easier than chopping everything up :-)
@someguy9175 Місяць тому
The problem with that is that then we have to melt down the whole stick to temperature and then cool it down very fast so it can spool, the thermal mass is just too high right? Maybe that could be solved by using some sort of chiller just bellow the nozzle? Like placing a tiny radiator connected to a AC unit in front of a high speed delta fan

TPU can be ironed onto cloth directly and there is no need for any adhesive. Place the tpu patch down first onto a wax paper, place the cloth over that and a final layer of wax paper then iron on the patch heating through the cloth. The only thing that really takes any practice is melting it with even pressure and not keeping the heat on for to long smearing the tpu out. The results can be great and hold up to many washes before a corner starts to peel off but its no big deal you just iron it again.

An interesting proof of concept, and for someone willing to put in the time probably quite practical and useful. One thing comes to mind, reversing the process, printing PLA onto baking paper stuck down on the build plate (would it stick - don't know), then printing the glue on top of that. The print could easily be lifted with the paper and is already ready for ironing onto the fabric.

@cristopherkurtin7858 Місяць тому
One thing that comes across my mind as an issue would be the amount of material you're pushing into extruder with one stepper motor step. Wider cross-section of the raw material makes fine control over filament feed more difficult, as the nozzle diameter still remains ~.4mm
@cristopherkurtin7858 Місяць тому
I guess the solution in that case would be adding a gearbox to fix the ratio between stepper motor and feeder gear, but then you'd have slower retraction speed, etc., etc. So while fixing the root issue, attempting to create a custom extruder would definitely bring some new problems into play :)

I can also see other possibilities for applications of the hot glue printer. Perhaps something along the lines of using it to fuse two previously printed parts or fusing two different materials. Of course, you could easily do that by hand, but on a mass-scaled assembly line, it would be very productive.
@adamc7779 22 дні тому
It might help with feed and heat soak if you cool the glue filament strand down before it enters the drive gear. Something as simple as a PTFE tube inside a bowl/bottle of ice water could help lower the temperature enough to reduce its adhesiveness. Also, preheating the cotton shirt with the iron prior to putting the sticker/logo on would probably help with the amount of back heating needed for adhesion and could minimize the TPU melting issue.

In the paper industry they use a glue press to apply paper roll headers to the end of the shipping roll (rolls a large, ½ ton to 1 ton). These presses use a heat activated glue. Sometimes the glue is pre-applied and sometimes it's sprayed on with what looks like a sprayer used to paint a car. I'm sure the nozzle is larger and the air pressure is higher. Try Searching Greif Roll Headers and Wraps. That should give you an idea of what I'm talking about.

I have had excellent results with a very thin two layer print of TPU ironed on with baking paper at high heat. And it stayed on after many machine washes. Now over two years later the deep black of the logo is the only part not faded still holding on very well.

I forgot to mention that you iron the fabric into the TPU from the reverse side.

May I ask what hardness/brand TPU you used?

It's funny, I always tell people this is what a 3D printer is in its most basic form. The fact that you actually made this video is AMAZING 😂

I've always wanted a 2nd sidecar nozzle that will deposit cheaper Hot Glue into the voids in my 3D prints to add heft and weight to 3D prints.

What a fun idea!

As someone who has cut the glue blobs can confirm that glue is very durable too.. They don't break apart so easily.. So a great layer adhesion.
