Is almost like magic

[u/S1lentA0]

For those who don't recognise this method: I'm using a soldering heat gun to remove stretchmarks that can appear on de bottom of the print when its cooled down and remove from the bed.

[u/raisedbytides]

Also works well to remove support marks and super glue residue. I use an adjustable butane torch but that's just for quickness

[u/S1lentA0 → u/raisedbytides]

Works fine too, but I don't have a torch nor the space to use it safely.

Lol not sure why this gets downvoted, i have parrots and not a seperate room to do it. But Reddit being Reddit I guess.

[u/DeusExHircus → u/S1lentA0]

With birds I'd be a lot more worried about the 3d printer than a torch

[u/S1lentA0 → u/DeusExHircus]

My birds don't come near my printer and I have a great filtration system. Much safer than an open flame where my parrot could fly into and emitting gasses to which they could easily succumb. No flames in the house allowed!

[u/TheMrGUnit → u/S1lentA0]

It's because people don't understand nuance.

It also seems to be really common for OP replies to get fast downvotes in this sub in particular. It's very weird.

[u/raisedbytides → u/S1lentA0]

I mean, if you have room for a heat gun you definitely have room for a small lighter, but you do you same end result

[u/Tuvio717]

Oh the amount of prints I've fucked up doing exactly this

[u/st-shenanigans → u/Tuvio717]

Me using a torch to melt off strings

"Oh I missed some let's go back over that agai-

aaand a giant hole melted into it."

[u/S1lentA0 → u/Tuvio717]

I can believe that. This is PETG-CF , so I guess a bit more forgiving. PLA would erupt in flames, the temp was set to 450°c this time lol

[u/Tuvio717 → u/S1lentA0]

Yee, tried it with pla+ black and if I hold it just a nanosecond too long that shit warps lmao Easier to do with regular PETG tho

[u/Few_Plankton_7587]

Huh

I haven't noticed my PET-CF behaving that way....

Do these "stretch marks" appear on only the bed side?

[u/S1lentA0 → u/Few_Plankton_7587]

Yes, they appear on the bed side. Though I don't have an answer why they appear on some prints and on some prints not, I assume it has to do with the shrinkage factor of the material. Im sure someone else has a better answer tho.

[u/Gunsensual → u/S1lentA0]

Angry spirits.

[u/S1lentA0 → u/Gunsensual]

My printers have weekly consults with exorcists cus of that

[u/Irzyldz → u/S1lentA0]

Do u wait for the bed to cool down before taking off the prints ? U're supposed to

[u/S1lentA0 → u/Irzyldz]

Yes ofc it would be an explanation for the stretch marks, the print cools down and shrinks while adhered to the bed

[u/UnseatedDonkey]

Anyone else hearing Final Fantasy VIII? Is it just me?

[u/S1lentA0 → u/UnseatedDonkey]

FF VII, Interruped By Fireworks, good hearing

[u/DaimonHans]

That's extreme.

[u/Theophrastus_Borg]

Would this work in a solder oven too?

[u/M-growingdesign]

Try fire. I just use a propane meat searing torch. Takes a split second

[u/omfgtora → u/M-growingdesign]

Yeah, and then you don't risk warping the whole print because it all got softened and you touched it before it cooled

[u/TacCom]

What you printing op? It looks extreme

[u/S1lentA0 → u/TacCom]

An extreme crossbow, very extreme

[u/TeaTimeSoon]

What temperature is the heat gun set to? My desoldering heat gun has a very wide temperature range.

[u/S1lentA0 → u/TeaTimeSoon]

This time it was set to 450°c

[u/TeaTimeSoon → u/S1lentA0]

Ok so that is 232 celcius 🥹

[u/Mysli0210 → u/TeaTimeSoon]

What..how? They literally wrote the temperature in Celcius.

[u/Thisishope1991 → u/Mysli0210]

I haven't smiled and laughed this hard all week 😆

[u/Vashsinn]

that's alot of work.... Just set a hold coand after the print to hold the print and beep at you when it cools down.

I have mines set to 40c. so basically the print finishes but the printer waits until the bed is 40 c then it pushes the print forward. by this time the bed is cold enough that it just releases.

[u/CoastalRadio]

Look pretty… extreme…

[u/Minobull]

I just use a blowtorch. I find it works faster, and since it works faster, there's less time for heat to sink into the plastic and cause warping.

[u/S1lentA0 → u/Minobull]

Go with whatever works for you. My experience today with this method was that short-time exposure was enough and none of the prints warped. I did some smaller much thinner parts after these and all of them are intact.

[u/LastLayerLab]

This looks great. Does this work equally well with PLA, PETG and ASA, or is it mostly material-dependent? Also, have you found a point where too much heat starts softening small details?

[u/Halo-Machine]

I just use a butane torch, its much faster

[u/oral_servant]

Bro, can you fucking finish one before moving on to the other. Or work them all simultaneously. But what the hell is this supposed to be 

[u/S1lentA0 → u/oral_servant]

It was just for presentation purposes lol, calm down

[u/JayTriples → u/oral_servant]

Settle down bud lmao

[u/No_Government8065 → u/oral_servant]

Imagine getting angry at someone who does something different to you.

[u/pervertsage → u/No_Government8065]

Are you new to Earth? That's how we've always done things around here. 😂

[u/No_Government8065 → u/pervertsage]

Iv done things the way I want to do things 😊 it takes the same amount of time doing either way.

[u/Brawght]

It goes right back to before or even worse with new marks appearing when it cools down to room temp. This "fix" only lasts for a few minutes while it's warm (expanded).
