Hello

I was searching for days now what material the blue self adhesive protecting film, that photoresist Pcb's have, is made of or where to buy it but have no luck.
I have even contacted Bungard support but they didn't reply.

Does anybody know where can I buy this film or what material it is?

It makes a great surface for printing PLA on it.
I have not tried ABS.

Thank you

Google 'Dry Film Photo Resist'

The protective sheet is usually polyester aka Mylar...

I am using Riston-215 film photoresist made by DuPont company. You can ask it directly from DuPont or find reseller on ebay by keyword "riston".

I'm not looking for the photoresist film but for the protective film that it over the photoresist PCB

Hi sgoum,

I'm using the TESA tape for painters. It works very well with PLA at 60ºC bed.
I now it's not what you are asking for but...

Happy printing!

I use glass larger than the heated bed, first advantage is you will be surprised how un-level your bed is.
using 5 20x20mm heat transfer pads, no loss of heat to glass plate, with no ongoing cost for painters or other tape.

I do not use heated bed, I'm to lazy to build one :)
I have tried different surfaces just to find the perfect one.
Glass with carpenters glue was very good.
This protecting film looks to be better.
I have it on an aluminum table.

With some friends we are developing a 3d printer for commercial use and try to find the best solution.
For some reason I don't like heated bed, maybe because I have never used one.
Unfortunately I will have to use heated bed cause I can not find any info about this film :(

 

I told you exactly what the protective sheet is, what more do you need?

Google up 'polyester film tape' and find the width you need, order...

CocaCola I did but the photos that show up didn't look exactly like the one on the PCB so I thought I missed something in your answer.

Thank you again

ps The one I use is like in link below

Why not include that picture and more info in your initial post, it would have helped greaty?

That is simply a generic 'surface protection film' that is commonly used to protect the finish surface of things like aluminum sheet, stainless sheet or clear acrylic...

Common human attitude, things we know make us think that are common knowledge :)

Where can I buy this film?
Is it also polyester?

How about kapton tape? Isn't it good enough?

There are double sided kapton tape with adhesive on both sides, be prepared to get difficulties on removing the printed thing from it...  ;)

Another common human attitude is that some expect/demand someone hold there hand every step of the way and present everything to them on a silver platter, so they don't have to actually do anything themselves...

And yet another common human attitude is ungratefulness when some provides them help but they expect more...

And that all points to yet another common human attitude, laziness!

Did you even try a Google search for 'surface protection film' and have a look before you posted an attack towards the one actually helping you and providing the answer to the question you asked?  I suspect NOT!  Especially since I highlighted the specific search phrase and even told you exactly what uses and industries it's commonly used in...

Here is my last helping hand for the lazy, you are welcome...

How thick is the glass and is it soda lime or borosilicate?

Good to know the dimensions of the platform as well

I think you misunderstood. I've made a self sarcasm and in no way wanted to offend you or anybody.
I thanked you in every post you made helping me.

I have searched using google and also contacted bungard and also posted at edaboard before posting here.
If I have found what I was looking for I wouldn't ask for help.

I'm not here looking for trouble, I just need to find some info.
As i wrote before we are in the process of developing a commercial 3d printer and laziness is not an option.
Thank you again for helping me.

ps just to complete the sentence

Common human attitude, things we know make us think that are common knowledge so I was not smart enough to think that it will not be clear to others what I was looking for.

So it seems that you are looking for a surface protection film not unlike what is commonly found on new electronics, auto accessories and similar. Is that correct? I presume this protective film is intended to be applied to finished surfaces of your product to prevent marring during shipping.

You can find a number of such products on the marketplace, but here are a few links to review:
Poli-tape (http://www.poli-tape.de/en/products/tapes/surface-protection-films/)
3M Temporary Surface Protection Tapes (http://solutions.3m.com/wps/portal/3M/en_US/Adhesives/Tapes/Products/~/3M-Tapes-3M-Adhesives/Protective-Coatings-Films-Tapes/Temporary-Surface-Protection-Tapes?N=6136&rt=c3)
Global Plastic Sheeting (http://www.globalplasticsheeting.com/polyethylene-film--sheeting-surface-protection/)

Is this similar to what you want?

I think the problem is OP added the word photoresist in his post,
I don't think any pcb shop use a protective film with photoresist content.
That said it is clear as mud, he want's a film to build 3d prints on.

Glass is 1/8th" the size is larger than the build area using 4 large bulldog clips and 2 angle profile under the bed, with the clips placed to outside the head tool path, easy to place if you build on a raft. Which I think is easier than coating the bed with slurry mix or using painters tape.
you need to adjust your top limit sensor, so software knows your new bed is now 1/8" higher than normal.

Oh, I just saw the part where he said "I'm not looking for the photoresist film but for the protective film that it over the photoresist PCB". I missed the part about the heated bed... thought he was looking to protect a 3D printer. :) I see that polyimide/Kapton is used for some 3D printing applications, but then he said he's not using a heated bed. :/ Strangely, I've read that hairspray can provide a good surface for 3D printing on glass, and it's easy to clean off.

A glue-stick, like the kids use in school, works really well, also.

The best is dissolved ABS in acetone.

Those are on a heated bed and for ABS. I haven't done any PLA on my own machine.

Kapton is expensive and gets torn up.

The film you are after is polyethylene. Tons of people make it in an adhesive form. Prove my thinking wrong by reporting back to us in this thread that it does work- I have my doubts.

Pickit2 - none of us know what printer you have could be 3x3 inches all the way out to 36x36 inches. What are the build plate dimensions on your printer so we can understand the pad placement.
