My CR20 has a G10 print bed with a fake build tack surface applied as a sticker. After watching this video, I flipped the bed over and the result was amazing. The first layer surface has a mirror finish like glass. Forget the over documented and KZbind "Must Have" upgrades. This tip has been the single biggest improvement in my 3D printing since I started.

to elaborate for anyone else that stumbles in here, you want to let the temperature lower on the sheet as evenly as possible, else itll shatter as one part cools faster and bends, well its a glass like thing, glass doesnt bend it shatters. need to heat it evenly too or the same will happen if it even matters for this material. also unless itll adhere to stuff at that temperate wouldnt any sort of really flat+smooth and rigid material work (e.g. a metal sheet?)

So far no issues and 10 prints in the release when cooling is excellent. I've been using 60 degrees on the bed and when it gets to room temperature (around 18-20 degrees) the prints just pop off, even at close to 30 degrees prints come away with very little effort (you can't say the same for the glass beds!).

No need for bed clips with G10. It's very easy to form under heat. Just take a heat gun along the edge and use a ruler to push it squared with the corner, when it cools it'll shrink just enough for an interferrence fit.

[@hyksos2]

I know this is very old, but I also had lot of trouble with initial layer adhesion with PETG, even if I cleaned with alcohol, my trick to print PETG is to increase bed temperature to 90 degree and hot end to 250, then disable fan for the initial layer, after the initial layer bring fan and temperature to normal setting (bed to 80, hot end to 240), I had 100% success rate with this.

[@EnricoConca]

I guess that the G10 sheet deforms because you are hitting the glass transition temperature when printing. It might be worth to experiment with higher Tg FR-4 (155 °C is common in PCB manufacturing, 170 °C is also available)

[@0thorgal0]

As the fiber glass is bound with epoxy resin in G10 it do not have a glass transition temperature. And I remember that 120-150°C is the point then most of epoxy resins will start to desintegrate when kept under those temperatures for longer period of time. The deformation is solely done by the forces that would otherwise cause delamination or warping.

Look up examples on epoxies and their glass transition temperatures. This is something you can easily find by googling.

Most polymers are like this, thermoset or thermoplastic.

So a word from someone who works at a circuit board manufacturer: Good luck getting FR4/G10. The stuff is weeks out in supply. As another note, FR4 is good, but make note it does absorb moisture to about .1% by weight. I also suggest not bending it too much, where FR4 is a great material, it does tend to be brittle, so don't bend it too much. If you start to see white spots form on it when you bend it, then you've bent it too far and started to deform the resin and glass bundles in it. FR4 is a material that's a mixture of resin and glass bundles/grains that go in a certain direction in a weave pattern. Tg is about 180ish, but note that after that it deforms. Feel free to ask me any questions about the material, it's the most common material in our shop, but we do have many, many other materials in our shop, from fiber glass, to ceramic based, teflon based, etc.

You are basically talking about a different material then, as the soldermask on top of the copper is another surface than the raw epoxy resin of an FR-4 PCB. If it still works for your plastics, thats great. But i guess you could end up having issues, depending on the soldermask they used.

[@knightsljx]

I managed to put a G10 print bed onto a Prusa MK3S+. You need a some sort of single sided spring steel sheet, I happen to have a Creality one, but you need one that has the bare spring steel exposed. And you need a 1mm G10 sheet. The closest on Aliexpress is a 250mm x 250mm x 1mm sheet. Then you must set your PINDA such that it is only about 1mm above the tip of your nozzle. Set the spring steel sheet bare metal side up then clip the G10 on top of the spring steel. This really pushes the limit of the tolerance of the available space for the PINDA to work. IF you encounter the tip of the nozzle colliding with the G10, the printer will throw an error. This means your PINDA probe needs to be lowered more. If you get it right, there will be just enough space for the PINDA to complete its mesh leveling and then you can do the Live-Z adjustment

Tip for keeping the build plate stuck to the aluminum bed: use some silicone thermal pad between the bed and the G10 surface. It helps with getting good thermal contact, and also provides a moderately-sticky surface to keep the build plate from sliding around at all. I currently use it with my glass bed and it's worked great without any clips.

[@brentowen8857]

Where do you get this thermal pad that is large enough?

[@TheEricSchubert]

@@brentowen8857 I bought mine on Amazon. I only found one that was 200x200mm, which worked okay for my Ender 3. But you can buy another and cut strips to fit empty portions of the bed. I will mention, now that I've used it for a while, that the bottom of the glass bed needs to be clean for it to stick well to the thermal pad. This happens a lot when I remove the glass bed. If I get fingerprints on it, the bed can gradually slide out of position. A bit of alcohol will fix it up again. But test that the bed won't move after replacing it. Dust and junk can also gradually get stuck in the thermal pad and make it less effective at sticking to the bed over time. I've recently swapped to a magnetic spring steel bed with PEI on it. That thing isn't going anywhere.

Thank you for the tips on G10! I use it on a Bambu X1C with high temp adhesive tape on their provided flex plate (the cool plate sticker kinda sucks so I removed it).

Now I can print functional PETG parts without a bumpy bottom surface. I wonder why PEI was 'chosen' as the go-to no-glue-stick build surface. Maybe the cost of applying it to a flex plate and a textured option?

I used clips to hold it in place and started printing. I am using a CR6SE and was having problems with adhesion with the stock build plate. I had already ordered a new one but I saw your video and cancelled the order, and I am so glad I did. After I put it in place and held it with clips and started printing. Amazing!!! started printing great right off. No issues I have been having with the stock build plate!!! It only cost me 5.99+tax. So much cheaper and much better. I will go to Lowes, find a sheet with the correct thickness and have it cut to size and many as the sheet will allow.

10:20 when having thermal runaway at extreme temps, try heating bed and hotend separately. It might be a power issue. Board is not able to cope with it. I encountered these on my Ender 3 v2 after modding it to all metal hotend, high temp thermistor etc. Happens only when going very hot.

Once you score the board with a knife bend it the other way, AWAY from the cut and it snaps in half much easier!

[@themeek351]

Wow, my dad had some of this stuff when I was just a kid! I wish I knew about this stuff years ago, since bed adhesion is the biggest issue I've had to deal with! The only problem with this material is the fact that both of my printers use the hot hotend to touch the bed in a grid to automatically level it, so I think it would melt it! Had this problem with buildtak too! So, I will have to change the order of the heating and leveling in the custom g-code and I will probably have to udjust the Z-offset to compensate for the thermal expansion of the nozzle! Thanks for this great video!

I hated nylon mostly because even in California scrubland with no rain all year it somehow still managed to soak up moisture and pop and fizz. Adhesion was a pain as well, I was using smooth PEI on a lulzbot mini with gluestick and it was hit or miss. Ultimately I ended up throwing away half the roll as it kept getting worse and worse with moisture like issues even though I kept it sealed up and in california with no rain in it's lifetime. I should have tried baking it at some point, but never did. I am in a much wetter area now and the thought of going back to it makes my eye twitch, heh.

@@Alluvian567 I live in GA. It’s always humid here. I’ve resorted to buying a medium size room dehumidifier, closing that room off, and running it at 100% for a day before printing Nylon. Actually have the dehumidifier’s drain tied into the A/C’s condensation water drainage line. That way it can run w/o having to empty the water. Power draw sucks when I run it like that…but it works. Afterward I turn the dehumidifier back to a reasonable humidity level and go on about my business. Since I use the same room for other things I want to avoid rusting it works out. Also, that particular room in my basement has no A/C returns or vents…so no humidity entering through the A/C directly to hamper the dehumidification process. This was my nuclear option. On the plus side…I don’t need to print from a dry box. I don’t know how low the humidity actually is in the room at 100% dehumidifier….but I do know I can feel the difference big time between that room and just outside the door.

[@octogunsalata]

Guys... this is called epoxy resin. When printing on either carbon or fiberglass, you're printing simply on epoxy resin. If you like the properties of it, you can convert any printing surface of your choice to it by simply getting some laminating resin and putting a thin layer of it onto the surface (after sanding and degreasing it), and then harden it in your oven for some hours, according to instructions. If putting it on spring steel, you shouldn't over-bend the plate of course as the epoxy film could break. (what, on the other hand, helps in getting it off if you want to renew it) The fibers only give it their stiffness and strength, they do nothing to the surface itself.

[@octogunsalata]

Hint: to prevent having a bulge form at the borders because of the surface tension of the resin, you should put a sheet of wax paper below that's larger than the printing surface and overlap the borders all-around a little with resin for about a half-inch. After hardening, you can carefully break or cut it off and sand it to get clean borders. However, it won't work with some of the exotic, overly thick printing surfaces that some people use, (like, several mm thick) as the difference in height to the wax paper is too large to have any effect. (depending also on the viscosity of the resin)

[@aidankilleen5889]

You're right, but the cost and availability is what's really on display here. I work at a machine shop that does a lot of plastic work, I wonder how some of that would do... PEEK, for example, and some proprietary blends...

[@octogunsalata]

​@@aidankilleen5889 The majority of inventions were discovered by trial & error and accidents, so, if you have access to unusual materials, I suggest trying to get your hands on some samples. However, before getting your hopes up after discovering a great, "new" material, I'd thoroughly check if it already has been discovered. In 3D printing, for example, I've seen plenty of unusual stuff exclusively in the world of highly expensive industrial 3D printers.

[@octogunsalata]

@@aidankilleen5889 Regarding PEEK - I think I've already seen printing surfaces made from it on a manufacturer site of industrial 3D printers.

I just checked. Its very expensive here. The best cost/value surface to me is the sandblasted glasses so far. I am just making them as many i want. No adhesive need on the surface, i put water on it if i want to remove the print earlier. I like the even matte surface.

[@vignesh_waran]

Does sandblasted glass require heatbed for printing pla and petg ?

[@h3ath3n99]

Thanks for the G10 tip! Been looking for a cheap solution to an increased bed size on an old machine. As per your TPU sticking too well... First of all I use no heat on the bed and secondly and most importantly I use a homebrewed tack that not only helps things to stick but also allows those that stick to well to release with ease. A 10:1 water:school glue mixture (or possibly an even higher dilution) in a simple squeeze bottle. I dollop about a nickel to a quarter sized pool on a 235x235 bed. You only need enough to dampen your print area, making it look evenly wet all over but not puddled. I apply it with a plastic putty knife, allow it to dry completely before printing over it. When I feel the need to revitalize it after many prints, I genlty wipe the bed down with a damp sponge as one application is good for dozens of reprints normally. If parts start to become hard to remove once again. Clean the bed and reapply. Also if you must, though I've never had to, you can dampen around your print with a sponge to easily solidify the already highly diluted water based tack to release your stubborn stuck print or literally rinse your part right off of your build surface at the water tap.

[@empty9360]

I have starting printing everything on FR4 (Fire Retardant Material that is like G10) only sanded it a bit with 200grid sandingpaper and it was such an improvement

[@janvaniersel9476]

I've been using FR4 1.5mm on my Prusa, on top of my steel bed to keep the pinda working. Just fits. Ever since I've been using it (6 months now), the prints (PLA and PETG) simply work beautifully. No needs for adhesives and after the cool down, the prints are often already fully separated on the print bed. After a lot of hassle, this makes it so much nicer. Thanks!

Wow--fabulous video!

I guess I never tried it simply because no one has been suggesting it for anything but nylon over all these years. I still have the old UMO but I just purchased a used UM 3 so I will be cutting some G10 build plates for it too and I plan to try printing a bunch of different materials on it.

ooh! this is so cool Angus! Thank you for sharing!! I love printing on smooth surfaces, and I gotta admit, the idea of a pastel pink bed is wildly appealing. 😁

[@OldCurmudgeon3DP]

Sorry to hear of your prior PETG woes. I've been using PEI on flex steel for about a year now and all I do between PLA and PETG is change the temp and add a smidge of clearance for PETG vs PLA. If I didn't already have a PEI sheet for my next printer, I'd get a magnet for some of this stuff and try it out.

[@piotrfila3684]

If it's the same material as PCBs then you could try printing on a custom PCB. Traces could be added on the other side for heating too, making the whole bed assembly really light. This could make 3d printers that move the bed (Prusa i3, Ender 3) print much faster and reduce ringing. Getting sponored by JLCPCB or PCBWay would probably not be too hard either :)

[@SianaGearz]

Uh FR4 PCB heaters are already a thing since early reprap days, cost maybe $3 for the 21cm size. But because the heater is embedded into the bottom layer, they warp and sag as they heat, they are like half a millimetre down in the middle when at operating temperature, which is a little much. This is why aluminium PCB heaters became common, they are more stable since the temperature is better equalised.

[@nedbazzvictoria6948]

Re: binder clips -- Have you tried photo frame clips? They're lot smaller on the top side and worked pretty well while I used glass. Might not fit a thinner bed profile though.

Yeah I just find them too fiddly to attach but could be a lower profile option!

[@tbbrady]

I don’t own a 3D printer yet but you could try slide clips to hold your surface down they are smaller then a bulldog clip so take up less print area they and also are reusable, and surprisingly strong. You would need the appropriate sized clips for the thickness your clamping and a dispenser. Search office works to find slide clips and a slide clip dispenser.

[@realgoose]

I’ve had luck with blue painters tape. The nozzle can just print right over the stuff. The minimum I’ve found that does the job well is across each corner. Certain brands/types work better than others.

[@SianaGearz]

@@tbbrady huh not been aware of this thanks. Then again I bought Ultimaker bed clips, clones, and I just love them. I attached rear ones permanently with nuts, and front ones bent so they are between the nut and the spring, and they just swing out. It was only $3 total shipped and I can easily install and remove the bed, and there's no chance of clips shooting across the room and leaving a giant scratch in my monitor again.

[@scubadoo7951]

"Softer than your nozzle" sounds like an Aussie insult.😂

[@onesadtech]

G10 has been very common for years in knife manufacturing for scales and hard sheaths! Cool to see it being use in another hobby I am getting into. I wonder if FRN would make a decent print plate, it's extremely tough, the scales from my BM Mini Grip are insanely rigid for how thin they are when removed, always blows my mind. Not sure about heat resistance though.

[@reverse_engineered]

We have been using G10 as the build surface of our Solidoodle 3 for many years. It's the best thing we found for printing ABS. The bed itself is aluminum and originally came with a layer of Kapton tape, but the tape damaged quickly and was difficult to replace. We tried a glass sheet, but it was heavy, fragile, and parts often didn't stick well. We also use binder clips for holding the sheet on, and yeah, it sucks. I've had to modify the firmware to provide a keep-out area for the clips because it was too easy to accidentally run in to them. Here are a couple of suggestions for printing ABS on G10. ABS dissolves well in acetone. You can dissolve a bit of ABS into some acetone to make a thin slurry, then wipe a thin layer of that on the G10. This can give you very good adhesion (maybe too much sometimes!). You can also use acetone to clean up any ABS that builds up on the surface (ABS does not dissolve in isopropyl alcohol). You mentioned the ABS having a rough surface because it cools too quickly. If you can enclose the printer in a chamber, the heat from the bed and nozzle will tend to keep the ambient temperature much warmer so that the ABS cools slower. You can even add a separate heater to keep the chamber temperature warmer - say 40C. We found just adding some walls to the printer kept it warm enough to avoid the parts cooling too quickly. This really became an issue for layer adhesion; we found the layers didn't adhere well if the previously-deposited layer had already cooled down too much, so keeping the chamber warm to slow the rate of cooling helped to provide good layer adhesion. Our printer also doesn't have a part cooling fan, since we don't want to cool things so quickly. However, we do get a lot of stringing in our prints. Perhaps some combination of warm chamber with a part cooling fan would be ideal to get the filament cool enough to not produce strings, but still warm enough to provide good adhesion and prevent warping. By the way, we also found G10 by way of the combat robots we were building! One of our club members even has his own business designing and producing parts for antweight combat robots, so we had an ample local supply of G10.

Glad you like it :D i use G10/FR4 for years now. Recently took the thin stuff and glued it to a spring steel sheet. That way you dont need clips, heats faster and is my absolute favorite surface :) great video 👍

@@super_slo I frequently print PETG on a Prusa mk2.5 with standard settings with a spring steel pei bed with no issues. I do generally preheat the bed to approx 40 degrees to remove the print tho.

@@super_slo for powder coated beds its less of an issue I think but those with a glued on sheet tear up after a while if you don't nail the first layer height.

[@winandd8649]

I'm using FR4 since one week now, it's a game changer!! Perfect for my printing (ABS and ASA) My sheet is 1.5mm thick, seems to do the job very well I heat it up to 100C, after cooldown the print is just sitting loose on the bed :-)

[@Rob_65]

Ah yes - thanks for reminding me of my first ever print surface. I used to print on fiberglass - I have some 4 and 6 mm sheets that I also use for mechanical purposes. I can confirm that the thicker sheets do work great for Nylon. As always: YMMV (your mileage may vary). There are tons of producers of this stuff and they all have their specific (epoxy) resin they use with a different max. temperature they can be used at. Regular G10 and FR4 comes with a different max. usable temperature. Regular FR4, PCB material, has a max. temperature of about 120 C which means that it will already be a bit softer at 100 C, resulting in the effects you have seen but this may also depend on the thickness of the sheet and how hard the material was pressed together in production. So for higher temperature use, you could try material from another company to see which one works best.

In theory it could work. Personally, if I did that I'd also add some kind of indexing method to keep sheet shifting to a minimum.

[@gryphonista]

I did it and it works Really Well. My Ender magnetic bed has alternating strips of North-South, which you discover when you place a magnet on it. I bought an A4 sheet of magnetic vinyl from Office Works and cut off 6 strips 1 cm wide. To those I attached the thin type of double sided tape. I removed the tape backing, placed the strips on the bed then placed the sheet of G10 onto the strips, rubbing over it to ensure a good adhesion. The G10 always aligns exactly as it was placed, ie perfectly. It's great to be able to take the sheet off, bend the print off, then replace the G10 perfectly without effort.
