<h1>read first</h1>
<p>When you use painters tape, you need to level your printer <strong>with</strong> the tape applied. You need to relevel if you change the tape type.</p>
<h1>Basics</h1>
<p>It's not <em>any</em> blue tape that printers love. There are basically two factors that make a tape useful:</p>
<ul>
<li>It has to stick during printing.</li>
<li>Its surface has to allow the filament to stick to it.</li>
</ul>
<p>Let's look at some <a href="https://www.youtube.com/watch?time_continue=2&amp;v=GIEaOdKVCO8" rel="nofollow noreferrer">different tapes</a> and their suitability - from my own experience.</p>
<h2>ScotchBlue</h2>
<p>The <em>original</em> blue tape is actually <a href="https://www.scotchblue.com/3M/en_US/scotchblue/" rel="nofollow noreferrer">ScotchBlue</a> for delicate surfaces by 3M. It has a good surface to stick to and at the same time an adhesive that does not degrade to unsuitability by heating. The delicate surface one is just as good as the all surfaces type. But don't use the outdoor type, it is sealed too much.</p>
<h2>FrogTape</h2>
<p><a href="https://www.frogtape.com/" rel="nofollow noreferrer">FrogTape</a> has an adhesive that has no problems with heating, the surface is sometimes a little smoother. Its green variant is about as useful as ScotchBlue, while the yellow variant is easier to remove - which can be an issue when the printhead is not calibrated correctly.</p>
<h2>Generic painters tape</h2>
<p><em>Generic</em> painters tape is a can of worms - there are so many different ones it is hard to describe. I have had very good off-yellow rolls from the dollar store of the 'fine surface' type - as in the tape had a fine surface - and their adhesive was good and didn't degrade too much under heat. The followup roll was a little thinner of material and released under heat so it can be a hit and miss - it's ok for starting out though.</p>
<p>I also tried a roll of UHU painters tape of the <em>easy remove</em> type and it was <em>horrible</em>, as it didn't want to stick after the nozzle went over it once even on an unheated bed.</p>
<h2>Generic blue colored tape</h2>
<p>I even tried two blue colored tapes from different dollar/hobby stores. One was ok-ish and had a similar result as the good dollar store tape in look, but left a blue shadow on the base of the print after two or three prints. The other was showing similar behavior to other mild-adhesive/easy peel tapes.</p>
<h2>Conclusion</h2>
<p>It's not <em>color</em> that matters, it is the <em>formulation</em>. If you must use blue tape, spend the extra bucks for quality. Some bloggers <a href="https://3dprinting-blog.com/61-trying-out-different-kinds-of-tapes-for-3d-printing-on/" rel="nofollow noreferrer">compared other tapes</a>, tested <a href="http://www.3dprinterprices.net/kapton-tape-vs-blue-painters-tape/" rel="nofollow noreferrer">ScotchBlue vs Kapton</a>, <a href="https://all3dp.com/2/3d-printer-tape-the-best-tape-for-better-adhesion/" rel="nofollow noreferrer">discussed the benefits of either</a>, <a href="http://www.desiquintans.com/bluetape" rel="nofollow noreferrer">discussed the ScotchBlue tape in depth</a>.</p>
<p>While in general, I prefer to print on the surface of my (blue) BuildTak (clone), I occasionally whip out painters tape on an unheated surface for very delicate prints: I remove the print together with the tape from the surface, which allows better handling. Sacrificing a layer of tape only costs some cents after all while breaking a print is hours and filament for much more  money wasted.</p>

I like this comparison of the blue tapes. Very useful. It would appear that branded tapes are superior - that is good to know. The Frog tape looks most interesting, especially as  Pᴀᴜʟsᴛᴇʀ2 also [mentioned it](https://3dprinting.stackexchange.com/questions/9981/why-does-the-painters-tape-have-to-be-blue?noredirect=1#comment16452_9981).

<p>To answer your question, <strong>it doesn't</strong> have to be <strong>blue</strong> tape!</p>

<p><a href="https://i.sstatic.net/3lFoe.jpg" rel="nofollow noreferrer"><img src="https://i.sstatic.net/3lFoe.jpg" alt="White or cream tape on heated bed"></a></p>

<p>To be honest, tape is not <strong>my</strong> favorite bed adhesion solution, there are plenty other options that work better than tape. </p>

<p>Often you'll see references to blue painters tape (of a certain brand) to be used as a bed adhesion layer because many people have good experience with that. I have tried several tapes, white/cream to blue from various vendors but found that neither of the tapes satisfied my personal needs. To name a few: cleaning, application, preparation, repair, tear-off, no glossy first layer, color of tape sticking to printed part, etc. did not make tape a favorite bed adhesion solution. Instead I've been printing directly onto aluminium and glass using an adhesive (3DLAC or DimaFix) to stick filament to the bed. Use a wet cloth to wipe residue off, spray can to apply a new layer, et voila, just print, it always sticks! Glue stick is also a possibility.</p>

<p>So while the community screams <strong><em>"use blue tape"</em></strong>, you just cannot use <strong><em>any</em></strong> blue tape from any tape manufacturer. There is no standard to which blue tape has to comply. Generally, speaking from painting experience, many blue tapes release much more easily after use while the white/cream paper tape sticks better and often tears (but this is frequently the tape that is already applied on heated beds of many Chinese printer kits, see image above). Not all tapes are equal: I have used blue tape from a local cheap source that will not stick to the build plate when it heats up, even if properly cleaned. </p>

<p>I'm more inclined to think that the color of the tape is just a way to distinguish yourself from the market back when the first manufacturer introduced the tape. Now that it is more common, others have adopted the color mimicking the tape they want to copy. It is more about the adhesive than it is about the surface of the tape (as in: "tape is rougher than the substrate you stick it on"), also you read that many people using blue tape need to prepare it by cleaning it (remove waxy layer) and sanding it.</p>

<p>IMHO, you just need to experiment yourself with several solutions and see what works best for you, could be that the white/cream tape from a local source also does the job. So basically, your tape does not have to be <strong><em>blue</em></strong>, it has to <strong><em>work</em></strong>!</p>

to my knowledge, one of the first blue tapes was ScotchBlue by 3M, which has good results, while I had better results with cheap dollar store tape than some no-name blue tape.

I've used generic and 3M blue tapes for many purposes other than printing (painting, holding finished woodwork together during repair, ...) and they've all consistently nit damaged the surface with their adhesive, whereas normal masking tapes always do damage it. For printing however the non-adhesive surface is probably what you care about. Adhesives won't harm glass anyway and probably won't harm aluminum.

Well yeah but they differ from tape to tape I'd think. I'm spoiled to have joined the fun post-buildtak so I've never had to fight with adhesion myself. My point was just that the motivation for using blue tape might not apply with common surfaces it's used on for printing.

<p>The second image isn't exactly painter's tape. Both images are types of masking tape, but the common manila/cream-colored masking tape vs the blue or green painter's tape <em>typically</em> has three features that make it less desirable for bed adhesion:</p>

<ol>
<li>Stronger glue holding the tape to the bed, that will make it harder to change later.</li>
<li>Narrower strips, so it's harder and takes longer to place the tape on the bed.</li>
<li>Thicker, softer material. This is <em>good</em> for filament adhesion, but bad for separating from the filament after the print and accurately leveling the bed.</li>
</ol>

<p>Again: those are only typical arrangements. You can get blue painters tape at the same narrow width as manila masking tape, and you can get wider or thin manila tape. It's more a matter of what you'll commonly find for sale, and in all probability the manila/cream-colored tape will work just fine.</p>

<p>Of course, I don't know what kind of tapes you have. My experience with blue tapes is, that they seem in general softer and "nicer" than white tapes. Their structure appears denser and they seem to have longer "furs" while the white ones are "dryer" and "sharper"</p>

<p>This surface makes the blue tapes I sourced more suitable as the molten filament catches more furs.</p>

<p>Here are magnified photos of my comparable tapes. Unfortunately, my microscope is pretty lame but at least we can take a look on closeups:</p>

<p><a href="https://i.sstatic.net/b3h01.jpg" rel="nofollow noreferrer"><img src="https://i.sstatic.net/b3h01.jpg" alt="white tape"></a>

<p>This comparison shows the lower density of my white tape better:</p>

<p>above shows that this white tape is made out of flat plastic fiber as they shine when illuminated from different angles</p>

<p>this could lead to another question</p>

<p>is such tape melted in any way in contact with extruded filament?</p>

<p>worth to analyse...</p>

Blue tape is just a descriptor that describes exactly what is on the tin: it is blue. But nothing more. There are many many different types of painters tape. There are several of them that are blue. ScotchBlue is what is meant most often. Nothing makes a tape in blue better than for example green one or bleached one.

With the blue tape I have experience with this is the case as well. It is higher quality, denser fibers, and a better quality adhesive. It has nothing to do with being blue other than being a higher quality tape that was the color blue and that became known. At this point I’m sure you can buy a lower quality blue tape as well.

I don't have a "sure" answer for you, but I bet it's because it doesn't leave residue on the bed. The masking tape would work fine, because it's the texture which gives it the grip. You just don't want to have all that goooooo on your bed. BTW, there's green painter's tape as well, though I haven't tried it in printing ... used it for painting and it's great for getting off of the working surface ... better than even blue.

I always thought the tape was blue so that it would stand out against the material it's used on, so you can make sure to remove all of it after the fact.  This of course would be problematic if your material was also blue, in which case you'd want some other color.

Try some on a small area. I just started 3D printing two weekends ago, finally getting good results this weekend.  PLA on name brand blue painters tape is working well.  Good adhesion and the tape can be peeled up to start lifting the part after the bed cools from 60C to about 55C so that a new pieces can be started (chess set, lots of pieces).  Other tapes may not adhere as well, or be removed as easily after being heated for hours at time. (I've also been able to lift the piece slowly and left the tape intact, getting 4 or 5 pieces printed at the same spot. 6th piece lifted after 5 minutes)

Yes, it's cheaper, and has the added advantage that it doesn't work too well, and leaves amazing amounts of crud on your build plate.  I ran out of blue tape one winter weekend and, instead of braving the snow and slush, substituted ordinary wide masking tape.

Of course, I don't know what kind of tapes you have. My experience with blue tapes is, that they seem in general softer and "nicer" than white tapes. Their structure appears denser and they seem to have longer "furs" while the white ones are "dryer" and "sharper"

This surface makes the blue tapes I sourced more suitable as the molten filament catches more furs.

Here are magnified photos of my comparable tapes. Unfortunately, my microscope is pretty lame but at least we can take a look on closeups:

[![white tape](https://i.sstatic.net/b3h01.jpg)](https://i.sstatic.net/b3h01.jpg)
[![blue tape](https://i.sstatic.net/zhJeZ.jpg)](https://i.sstatic.net/zhJeZ.jpg)

This comparison shows the lower density of my white tape better:

[![white over blue](https://i.sstatic.net/Wm6Rb.jpg)](https://i.sstatic.net/Wm6Rb.jpg)
[![white next to blue](https://i.sstatic.net/nwTLh.jpg)](https://i.sstatic.net/nwTLh.jpg)

to complete the picture here goes angle photos which reveals some more details

[![enter image description here](https://i.sstatic.net/rFzMO.jpg)](https://i.sstatic.net/rFzMO.jpg)

above shows that this white tape is made out of flat plastic fiber as they shine when illuminated from different angles

this could lead to another question

is such tape melted in any way in contact with extruded filament?

worth to analyse...

# read first

When you use painters tape, you need to level your printer **with** the tape applied. You need to relevel if you change the tape type.

# Basics

It's not *any* blue tape that printers love. There are basically two factors that make a tape useful:

* It has to stick during printing.
* Its surface has to allow the filament to stick to it.

Let's look at some [different tapes](https://www.youtube.com/watch?time_continue=2&v=GIEaOdKVCO8) and their suitability - from my own experience.

## ScotchBlue

The *original* blue tape is actually [ScotchBlue](https://www.scotchblue.com/3M/en_US/scotchblue/) for delicate surfaces by 3M. It has a good surface to stick to and at the same time an adhesive that does not degrade to unsuitability by heating. The delicate surface one is just as good as the all surfaces type. But don't use the outdoor type, it is sealed too much.

## FrogTape

[FrogTape](https://www.frogtape.com/) has an adhesive that has no problems with heating, the surface is sometimes a little smoother. Its green variant is about as useful as ScotchBlue, while the yellow variant is easier to remove - which can be an issue when the printhead is not calibrated correctly.

## Generic painters tape

*Generic* painters tape is a can of worms - there are so many different ones it is hard to describe. I have had very good off-yellow rolls from the dollar store of the 'fine surface' type - as in the tape had a fine surface - and their adhesive was good and didn't degrade too much under heat. The followup roll was a little thinner of material and released under heat so it can be a hit and miss - it's ok for starting out though.

I also tried a roll of UHU painters tape of the *easy remove* type and it was *horrible*, as it didn't want to stick after the nozzle went over it once even on an unheated bed.

## Generic blue colored tape

I even tried two blue colored tapes from different dollar/hobby stores. One was ok-ish and had a similar result as the good dollar store tape in look, but left a blue shadow on the base of the print after two or three prints. The other was showing similar behavior to other mild-adhesive/easy peel tapes.

## Conclusion

It's not *color* that matters, it is the *formulation*. If you must use blue tape, spend the extra bucks for quality. Some bloggers [compared other tapes](https://3dprinting-blog.com/61-trying-out-different-kinds-of-tapes-for-3d-printing-on/), tested [ScotchBlue vs Kapton](http://www.3dprinterprices.net/kapton-tape-vs-blue-painters-tape/), [discussed the benefits of either](https://all3dp.com/2/3d-printer-tape-the-best-tape-for-better-adhesion/), [discussed the ScotchBlue tape in depth](http://www.desiquintans.com/bluetape).

While in general, I prefer to print on the surface of my (blue) BuildTak (clone), I occasionally whip out painters tape on an unheated surface for very delicate prints: I remove the print together with the tape from the surface, which allows better handling. Sacrificing a layer of tape only costs some cents after all while breaking a print is hours and filament for much more money wasted.

> **Comments:**
> **username_0**: I like this comparison of the blue tapes. Very useful. It would appear that branded tapes are superior - that is good to know. The Frog tape looks most interesting, especially as  Pᴀᴜʟsᴛᴇʀ2 also [mentioned it](https://3dprinting.stackexchange.com/questions/9981/why-does-the-painters-tape-have-to-be-blue?noredirect=1#comment16452_9981).

To answer your question, **it doesn't** have to be **blue** tape!

[![White or cream tape on heated bed](https://i.sstatic.net/3lFoe.jpg)](https://i.sstatic.net/3lFoe.jpg)

To be honest, tape is not **my** favorite bed adhesion solution, there are plenty other options that work better than tape.

Often you'll see references to blue painters tape (of a certain brand) to be used as a bed adhesion layer because many people have good experience with that. I have tried several tapes, white/cream to blue from various vendors but found that neither of the tapes satisfied my personal needs. To name a few: cleaning, application, preparation, repair, tear-off, no glossy first layer, color of tape sticking to printed part, etc. did not make tape a favorite bed adhesion solution. Instead I've been printing directly onto aluminium and glass using an adhesive (3DLAC or DimaFix) to stick filament to the bed. Use a wet cloth to wipe residue off, spray can to apply a new layer, et voila, just print, it always sticks! Glue stick is also a possibility.

So while the community screams ***"use blue tape"***, you just cannot use ***any*** blue tape from any tape manufacturer. There is no standard to which blue tape has to comply. Generally, speaking from painting experience, many blue tapes release much more easily after use while the white/cream paper tape sticks better and often tears (but this is frequently the tape that is already applied on heated beds of many Chinese printer kits, see image above). Not all tapes are equal: I have used blue tape from a local cheap source that will not stick to the build plate when it heats up, even if properly cleaned.

I'm more inclined to think that the color of the tape is just a way to distinguish yourself from the market back when the first manufacturer introduced the tape. Now that it is more common, others have adopted the color mimicking the tape they want to copy. It is more about the adhesive than it is about the surface of the tape (as in: "tape is rougher than the substrate you stick it on"), also you read that many people using blue tape need to prepare it by cleaning it (remove waxy layer) and sanding it.

IMHO, you just need to experiment yourself with several solutions and see what works best for you, could be that the white/cream tape from a local source also does the job. So basically, your tape does not have to be ***blue***, it has to ***work***!

> **Comments:**
> **username_8**: to my knowledge, one of the first blue tapes was ScotchBlue by 3M, which has good results, while I had better results with cheap dollar store tape than some no-name blue tape.  
> **username_9**: I've used generic and 3M blue tapes for many purposes other than printing (painting, holding finished woodwork together during repair, ...) and they've all consistently nit damaged the surface with their adhesive, whereas normal masking tapes always do damage it. For printing however the non-adhesive surface is probably what you care about. Adhesives won't harm glass anyway and probably won't harm aluminum.  
> **username_2**: @R.. isn't every (paper) tape rougher than glass or aluminum.... the adhesive surface is very important, you don't want it to come loose and form bubbles, I've seen that happen with a blue tape brand.  
> **username_9**: Well yeah but they differ from tape to tape I'd think. I'm spoiled to have joined the fun post-buildtak so I've never had to fight with adhesion myself. My point was just that the motivation for using blue tape might not apply with common surfaces it's used on for printing.  
> **username_2**: @R.. Indeed new type build surfaces make printing way more easy! :)  
> **username_0**: 3DLAC seems to be the way to go then - if not using branded tape.  
> **username_2**: @Greenonline See e.g. [this answer](https://3dprinting.stackexchange.com/a/6861).

The second image isn't exactly painter's tape. Both images are types of masking tape, but the common manila/cream-colored masking tape vs the blue or green painter's tape *typically* has three features that make it less desirable for bed adhesion:

1. Stronger glue holding the tape to the bed, that will make it harder to change later.
2. Narrower strips, so it's harder and takes longer to place the tape on the bed.
3. Thicker, softer material. This is *good* for filament adhesion, but bad for separating from the filament after the print and accurately leveling the bed.

Again: those are only typical arrangements. You can get blue painters tape at the same narrow width as manila masking tape, and you can get wider or thin manila tape. It's more a matter of what you'll commonly find for sale, and in all probability the manila/cream-colored tape will work just fine.

> **Comments:**
> **username_0**: I was looking at getting 50 mm wide tape. There are sheets 200x200 but they are rather pricey, and the brand isn't specified.
