Holy shit. I do a fair bit of small electronics repair on the side, the cost of a decent heat pad is about half that of a 3d printer... This may be what finally inspires me to get a 3d printer.

domi ,

Can confirm this works, removed my tablet screen with my 3D printer.

Opening phones and heating burritos :)

And melting gallium when I 3D print moulds to make some silly metal objects (probably not so smart next to so much aluminium extrusion)

Wax is cheaper than gallium I think

SkidFace ,

Oh I know, I just have a few hundred grams of it since I like collecting elements, so I recast it into something funny when I’m bored

@HurlingDurling@lemmy.world avatar

Sound's fun. I've been meaning into getting into a 3d printing to casting process to make metal objects.

Not sure if this is really what you're asking about, but there are some laser cutting/engraving add-ons you can get. Basically replaces the hot end with a laser. After I upgraded to a Prusa MK4, I'm thinking about getting one of those for my old E3v2 and turning it into a laser cutter.

AspieEgg ,

Looks like they are using it to warm the screen adhesive so they can remove the screen and repair the phone.

RedBauble ,

Is that a motorola moto z2 play? I owned that phone and I used to disassemble it just like this!

Edit: saw in another comment that it's a z4. The camera did look strange for a z2 at a second glance

stoi ,

Also thought was a z2 lol. Loved that phone

rugburn ,

Ngl that's fucking genius

Maalus ,

Seeing as you can do the exact same thing with a hairdryer, it's inventing a solution to a problem that doesn't exist.

The heated bed is coupled to a thermistor. I'd argue controlling the temperature in order to not accidentally overheat parts of the phone is a step above a hair dryer.

herrvogel ,

Also bad is that hair dryers don't spread their heat around very well at all. You can easily create hotspots on the object and damage things with them.

dual_sport_dork OP ,
@dual_sport_dork@lemmy.world avatar

And, I don't own a hairdryer. (Or much in the way of hair, these days.) But I do own a 3D printer...

cm0002 , (edited )

A hairdryer or heatgun kinda work, but it's super easy to accidentally heat damage the display underneath (and it's sensitivity only gotten worse with these super fancy displays these days).

It also doesn't spread the heat very well.

This is a great solution because the bed is temp controlled and evenly spread

TootSweet ,

Doesn't that require a much higher temperature than most beds would be able to safely achieve.

I had to take the screen off of a Pixel not terribly long ago to replace the battery. I used a heat gun and I remember it requiring a temperature of like... 240C° or some such? And when I'm printing PLA, my printer bed only gets to 60C°. (Not saying it couldn't go higher, but 240C° seems way higher than 60C°.)

ThetaDev ,

No, that temperature would damage your screen. The professional hot plates for phone repair are typically set to 85-90°C. With a heat gun you may need to set a higher temperature since you are only heating up part of the phone and it cools down again during the process.
My printer (Prusa MK3) with PCB heater can go up to 120°C, so it looks perfect for the job.

Maalus ,

A heat gun is enough to melt through plastic, there is no need for higher temperatures. You can do it with a hairdryer.

marcos ,

You are thinking about a soldering plate? Those go up to 300°C or some times 400°C.

A phone screen is fixed with hot glue, that starts to melt around 60°C.

TootSweet ,

What I've used for this purpose is one of these. And I can attest that 60C° is nowhere near high enough to set that kind of thing for purposes of getting a Google Pixel 3a off safely.

But I bet ThetaDev is right that a flat plate heater can work just as well when set to lower temperatures because they heat the whole screen at one time.

RedBauble ,

Nah 85/90 degrees is perfect for the job. Much better and more uniform than a heatgun, let alone a hairdryer

dual_sport_dork OP ,
@dual_sport_dork@lemmy.world avatar

90 degrees was the spec for this job. 240 is way too high.

bruhbeans ,

Can I use it to warm up a sex toy? Asking for me.

Luccus ,

Sadly not.

I was told.
Without asking.
By a long lost friend of a cousin you wouldn't know.

My sex toy goes to a different school

My sex toy brings all the boys to the (local) yard

Imgonnatrythis ,

Just 3d print one and grab it while it's fresh and warm.

FuglyDuck ,
@FuglyDuck@lemmy.world avatar

I realize this is a joke…

But don’t do this. Really. The fdm layers are unhygienic, and there’s a not-insignificant risk of things snapping off and leading to awkward emergency room visits.

A better solution is printing a 2 part mold and casting silicone.

umbrella , (edited )
@umbrella@lemmy.ml avatar

glad to hear from the 3d printed sex toy experts in the house

wont the layers transfer to the silicone?

FuglyDuck ,
@FuglyDuck@lemmy.world avatar

You can process the inside to be smooth (sanding, priming. If you have a solvent - acetone for abs, as an example. And mold release.)

Even just using a filler/primer should be enough

nilloc ,

Aren’t ribs a good thing sometimes?

fruitycoder ,

I was really impressed by the lulzbot manual mentioning this! Its also important to consider that most 3d prints can be sensitive to water unless sealed too.

FuglyDuck ,
@FuglyDuck@lemmy.world avatar

I’m just gonna assume some one printed a butplug, had it snap off leading to said emergency room visit and they tried to sue lulzbot.

fruitycoder ,

Idk lulzbit are also just super consumer freindly out fit (I think are still one the only 3d printer that are FSF Respect Your Freedoms certified).

@synapse1278@lemmy.world avatar

Who is this someone you're talking about, FuglyDuck ?

HurlingDurling ,
@HurlingDurling@lemmy.world avatar

Yes, and you can also warm up lube as well.

I won't take any questions at this time

SzethFriendOfNimi ,

I’ve used it for releasing an iPad screen adhesive as well as for warming cinnamon rolls so they’ll rise when our oven was in use.

Totally had the food wrapped with Saran Wrap all around and had something between the plate and the glass pan. To make sure nothing that wasn’t safe for food prep didn’t touch it and to stop from “cooking” the bottom by accident.

@Gormadt@lemmy.blahaj.zone avatar

I've used mine for a lot of stuff really

Weaken adhesive for opening a cell phone (like your picture)

Revive a Nexus 5X long enough to patch it and transfer the data off of it (a really frustrating process BTW)

Heat treat resin prints (place print in box, set box on bed, set bed to 80C, come back in an hour, turn bed off, wait for it to hit ambient, remove box) this process is great for hollowed prints as not only will it cause and trapped alcohol to evaporate out but it will further cure the part and increase the durability of the part as well (CNC Kitchen has a great vid on it)

Keep my coffee warm while I was building and setting up a NAS for a friend

It was a very long day that started with a nice easy plan that quickly turned into "Which POS part is preventing this thing from working"

Fun fact it was the motherboard. Though it wasn't a consistent issue sometimes it was RAM failing, sometimes it was pcie not working, sometimes it was networking not working, etc. After swapping the motherboard everything worked beautifully.

Yes we tried reseating the CPU, yes we checked for bent pins, yes we made sure the cables were secure. Something was fucky with the motherboard.

Are those test pads on your phone?

dual_sport_dork OP ,
@dual_sport_dork@lemmy.world avatar

No. It's a Moto Z4, which is compatible with Motorola's "Mods" ecosystem which are a variety of accessories you can stick to the back. For data transfer they connect to those pads via pogo pins.

There are battery extender backs (which I have), a full-on gamepad case (which I also have) and also a 360 degree camera, a backplate that adds wireless charging, a mini projector, a beefed up speaker back, and an entire replacement Hasselblad camera you can stick on it as well. There was going to be a slide out physical keyboard module, too, which unfortunately turned out to be vaporware.

Bezier ,
@Bezier@suppo.fi avatar

That's a pretty cool feature.

unexposedhazard ,

This is an amazing tip tbh. Never thought of using it for that.

dual_sport_dork OP ,
@dual_sport_dork@lemmy.world avatar

Has anyone else found a use for their 3D printer that wasn't exactly listed on the label?

Postmortal_Pop ,

I used to use the heated bed to brew tea while I was modeling. Poly makes a good cup.

over_clox ,

Not from the 3D printing world, but sometimes I'd use our heating plate to reheat pizza LOL! Gotta make sure to clean the surface really well afterwards though.

kn33 ,

Sounds like a job for tin foil or parchment paper

Pofski ,

The wife and I once used it to keep our fondue warm.

FuglyDuck ,
@FuglyDuck@lemmy.world avatar

I know a guy whose cat will take naps on it.

Used to have problems with the cat sneaking up while preheating, and being very intent on not getting off. (Even with the cold hot end poking him. It was… hilarious. Took an old i3 and sacrificed the build plate to solve the issue though.)

psud ,

They need an enclosure

FuglyDuck ,
@FuglyDuck@lemmy.world avatar

it really was hilarious watching the cat stubbornly refuse to move out the way as the bed moved back and forth and the hot end poked it. the cat had this most baleful look like it was being martyred by the machine.

(Yes, the friend was careful not to hurt the cat.)

Bach37strad ,

Bed is good at keeping fresh krispy kreme warm.

B0rax ,

In an enclosed chamber, I warm it up to ~37°C to allow yeast dough to rise. Works like a charm.
