While most desktop 3D printers don't come up with glass beds by default, a glass impress bed is ane of the outset upgrades that 3D printing hobbyists and professionals make. A glass bed just makes a 3D printer feel more premium and professional. When used right, a glass bed volition requite yous results that will reverberate this impression quite accurately.
Earlier you go to a hardware store and buy a piece of glass for your impress bed, make certain to read through our listing of tips kickoff. A glass bed isn't a silverish bullet for solving all your 3D printing woes – it has to be used according to a few guidelines.
What are the advantages of using a drinking glass print bed?
A glass bed is practically a no-brainer addition to anyone's 3D printing accessories. However, if you still aren't convinced that converting to a drinking glass bed is worth the bother and the expenses, then are a few points which may make you alter your heed:
1. Consistently flat
Despite appearances, the build plate that comes with your 3D printer is probably not 100% flat. If it's made of sparse aluminum, and so there are probably sections of information technology that bow downward even when brand new. These deformations will worsen every bit y'all utilise your 3D printer, which will soon enough crusade problems with bed adhesion.
Compared to aluminum, glass has a much college modulus of elasticity. What this means is that it has less of tendency to deform under stress, whether mechanical or thermal. A glass bed will be apartment when you buy it and will remain flat even subsequently hundred of heating and cooling cycles. A high-quality tempered glass bed even has skillful scratch resistance, so its quality volition not deteriorate even if you use a scraper or razor to remove balance adhesives.
2. Easier to clean
The clarity and chemic stability of a glass bed makes cleanup a breeze. Later printing, your bed will likely end upward with a lot of excess adhesive. Fifty-fifty while stored and during handling, the bed can pick up dust and oils that tin can severely compromise the quality of bed adhesion. Since drinking glass does not corrode, you can safely clean it with some soap and h2o or even a quick wipe down with acetone. It's as well very easy to spot any dirt you've missed with glass – a task that'due south a lot harder with an aluminum bed that'south been painted black.
3. Prints remove cleanly
By its very nature, the surface of a glass is very smoothen. This smoothness transfers to the bottom of your print, making sure that they come up out with very clean and flat bottom surfaces. When washed correct, removing your finished print from a bed should also be almost effortless. With the struggle of removing your print eliminated, you can exist sure to preserve the quality produced past several arduous hours of printing.
4. More controlled behavior when heated
Glass has two properties that make it an first-class fabric for a heated bed: a low thermal conductivity and a high thermal stupor resistance. A low thermal electrical conductivity means that a glass bed heats slowly and evenly. As long every bit you're patient while your glass bed heats upward, you should end upward with a bed that with a consequent temperature all throughout. Better nevertheless, the temperature of a glass heated bed doesn't drop drastically because of drafts or changes in the temperature of the surround.
The 2d belongings is more important for giving glass beds longevity. When a glass bed is used on a heated build platform, its temperature increases quite rapidly. When the molten filament comes in contact with the glass bed, there could be more than 100 °C between the two, which can exist quite the thermal shock for the glass material.
What makes glass an excellent choice for a heated bed is that it has a greater capacity for withstanding sudden changes in temperature. Not all types of glass are created equally in this aspect. You lot demand to pick the right type of glass if y'all want the optimum thermal shock resistance, as we shall talk over in further detail later.
v. Inexpensive
A drinking glass bed may seem like a fancy improver to your 3D printer associates, simply it's really not that expensive. You likely won't need a huge slice of drinking glass, peculiarly if y'all merely have a desktop-calibration 3D printer. The toll tin can depend on the size of your print bed, but yous shouldn't take to spend more than than $30 even for a very large slice of glass.
In the long term, making the switch to a glass bed tin even finish up saving you money. Your prints will have better bed adhesion and will come up off easier, resulting in less filament wasted due to failed prints. A drinking glass bed will final a very long time and yous won't need to worry about replacing it frequently, like PEI or BuildTak surfaces.
Tips to get the best results when press on drinking glass
Getting a glass bed is no guarantee that your prints will come up out perfectly every fourth dimension. Not all glass panels are made equally and there are yet proper techniques that you need to follow. To make the most out of a glass bed, brand sure to follow these tips:
ane. Utilise glass that is about iii to four millimeters thick
Bring your caliper with you lot when yous go shopping for a glass panel to make sure that the thickness falls somewhere inside this range. This value is a adept compromise that makes sure that your glass bed is durable enough to withstand the thermal shock but non and so thick that it heats upward too slowly.
An exception to this rule of pollex would be if your print bed is exceptionally large. You'll have to go a thicker glass bed (close to 6 millimeters in thickness) to brand up for the added stress on the drinking glass due to its own weight.
2. Make sure you buy borosilicate glass
The cheapest drinking glass you can find is the soda-lime silicate variety. It'south inexpensive considering it may contain entrapped air bubbles which may stop up expanding when heated and creating cracks on the glass. Phosphate-based drinking glass also has the same vulnerability on top of a low chemic resistance, which means that you can't clean it with the usual solvents.
For the virtually reliable option, we recommend going only with borosilicate glass. This is the same glass used in cookware or the glassware used in laboratories. They are chemically resistant, accept no air bubbles, and are manufactured to be consistently flat and polish. There's really no other option when it comes to this attribute.
3. Apply tempered glass or ceramic glass, if possible
There are only two means to exercise meliorate than borosilicate glass – tempered glass or ceramic glass. Both these options might be more expensive, just they offer advantages which could prove useful for glass print beds.
Tempered glass is simply glass that has been treated to requite it better thermal stability. This means that they can be heated to higher temperatures with no ill furnishings. Most tempered drinking glass tin be heated to effectually 240 °C. If you plan to print with extremely high-temperature filament such as PEEK or ULTEM, then you may need to get a tempered glass bed.
Ceramic glass, the most popular brands of which is NeoCeram, actually isn't drinking glass – its composition is closer to a transparent ceramic. Dissimilar existent glass, ceramic glass tin go through repeated heating and cooling cycles without losing whatsoever of its mechanical integrity. For this reason, ceramic glass is often found in glass covers of stoves and fireplaces.
As a print bed, ceramic glass will last much longer. If y'all use your 3D printer at a very high output rate, you should consider investing in ceramic drinking glass.
4. Utilise binder clips to affix the drinking glass bed to your platform
Once you have your glass bed perfectly cut to the size of your build platform, affixing it to your 3D printer is a job for the apprehensive binder clips. This is a widely used practice by the 3D printing community that manages to hold the glass panel in place while withal allowing it to be removed without a fuss. Make sure to use pocket-sized folder clips that volition stretch out almost fully to accommodate the thickness of your print bed. This will ensure that the binder clips will not come into contact with any of the parts of your 3D printer.
5. Attempt to use glue stick for adhesion
Mucilage stick is the go-to adhesive of the 3D printing community. It's often the first choice because of how inexpensive information technology is and how piece of cake it is to apply. You tin even rub some gum stick on your drinking glass bed even when it's already mounted on your 3D printer.
The advantage of using glue stick on glass is that you tin just wash off the backlog glue with h2o when you're done printing. Glue does tend to brand print removal difficult, particularly if y'all set the bed temperature at high values. However, you can use the same technique of running the drinking glass bed under water for a few 2d to loosen the mucilage afterwards the print has cooled down.
6. If glue stick doesn't work, effort hairspray
Hairspray is some other favorite adhesion aid amongst the customs because how easily you can get it and how reliably it performs. Unlike gum stick, applying hairspray tin can go a bit messy, then it's best to remove your glass bed from your 3D printer and utilise the hairspray a good distance away. The spray awarding method should make it easier to become a overnice, even glaze. Let it dry for a few minutes before you install the glass bed.
As the glass bed heats upward, the adhesive power of the hairspray reactivates and provides first-class bed adhesion. When y'all're done printing and the drinking glass bed starts to cool down again, the hairspray reverts to its dried country.
If you're lucky, your finished print should come right off the glass bed when information technology's cool enough without any prodding. Even if it doesn't come off by itself, removing a print from hairspray adhesive should yet exist easier than if you used glue stick.
vii. Make certain your drinking glass bed is completely dry earlier you lot use it
We recommend cleaning your glass bed later every utilise with water and lather. What's fifty-fifty more than important is that you lot allow it dry completely earlier y'all put it on your build platform. The most dangerous affair you can exercise is to let drops of wet be trapped betwixt the build platform and the glass bed. When the glass bed heats up, this wet will turn to steam and will easily crack the glass.
Concluding thoughts
3D printing on a drinking glass bed is a luxury that gives you improve options in bed adhesion and results in overall meliorate quality of your finished prints. Thankfully, y'all don't need to spend a lot of money to become ane. Since a glass bed lasts for so long and should save you from a lot of wasted filament, it's well worth the investment.
Just proceed in listen that printing on drinking glass won't magically solve all the problems yous're encountering. Much like any other aspect of 3D press, press on glass requires technique and a deep understanding of the science behind its apply. If y'all tin can harness the benefits of 3D printing in glass, y'all tin open the possibilities of printing with more types of filaments.
3D printers should never be left unattended. They tin can pose a firesafety chance.
