I'm fairly new to 3D printing and was getting a bit discouraged with my results. I decided to give the Creality Ender 3 Glass Bed a try to see if it would help. It was a few dollars more than a few others I looked at, but it did not look like it was just a piece of cut glass that I could cut myself and it's not. The "microporous coating" looks and preforms great. As it says in their description, the adhesion is great. Also, once the glass cools, the printed items simply lift off. But the best part of this glass bed was the fact that I was able to level the printer bed better that I have ever been able to with the stock Ender 3 bed. My prints are coming out great, and I am very pleased. Well worth the price. Thinking of getting a second one just to have "in case"
One warning though, I did not lower my bed before I started a bed leveling test and the Creality glass bed is thicker than the Ender3 mat. This caused the extruder nozzle to scrape the glass bed. You can see this in the attached photo. I stopped the test quickly but nevertheless, it left a mark. I just was not thinking ahead and excited to try it. This has not caused me any issues with my prints. You can't really even feel it, but you can see it in the microporous coating. So, anyways, just a heads up. Lower your printer bed before running a leveling test.
My Ender 3 Pro came with the magnetic print surface a lot of people online are making a fuss about. No more having to use a scraper to get your print off the bed. Just remove it, flex it and peel off the print! Magic! Yeah, for the first 20-30 prints. Then, I noticed that there were creases in the sheet that would not self level. Printing a single layer calibration print showed various high and low spots on the magnetic sheet. So, I purchased this glass bed upgrade on a whim. After all, glass is pretty flat, right? Wow, was I surprised how good this bed was! I must have about 50+ prints of various sizes and print times done and every one of them is flat and absolutely ZERO bed adhesion issues. This glass sheet has a silicone carbon coating on it so no need for hair spray or glue stick. The only thing you need to do is keep it clean and let the print completely cool when done and it will pop right off. I used small binder clips to hold it to the heated bed and it just stays. Also, I haven't had the need to change the bed temperature for PLA after this upgrade. All-in-all a solid purchase.
I've had my Ender 3 Pro for less than a month and decided to try the glass bed. I'm finding it to be a wise investment.
Once the bed is leveled and the nozzle-distance sweet spot is found, I get excellent bed adhesion, and once the bed cools things almost remove themselves with a very good bottom finish.
The one thing I don't like are the clips (not included). I'm using small binder clips (other reviews have said medium, those are WAY too big) and they're working just fine, it's not slipped once, but those clips take up real estate. Considering the clips are $1 for 10-20 clips, it's worth allowing room for them when arranging models to be sliced in Cura.
Just make sure you lift your Z-stop a distance equal to the thickness of the glass and tighten the bed knobs all the way down BEFORE you auto-home your printer for leveling, or you're gonna crash into the bed. Also, Thingiverse has a Just Calibrate gcode that demystifies bed leveling and makes it easy.
Overall, I think this was a great upgrade and I probably would have done it out of the box. The stock magnetic bed that comes with the Ender 3 Pro isn't bad, but you get way better adhesion and bottom finish with the glass bed, and potentially less or no warping.
I am printing with PLA, and after the first couple days of printing on the 'sticky' side that has the printed dot pattern, I started running into problems with my prints not sticking properly. I had corners peeling up and small details were just not adhering well. It would take 2-3 starts before I could get a print to stick 'sort of' well.
I just tried flipping this over so that the smooth 'glass' side was up, and it was a night & day difference. The prints have stuck beautifully, no warping, no peeling, no details coming loose. As a bonus, the prints also are now coming out with that super shiny and smooth texture I have seen from other peoples prints on glass surfaces. Further, since it is just a glass surface, it is very easy to clean if any residue or finger grease gets on it.
At this point, I am a little annoyed that this comes with a coating at all. I would rather it was a little less expensive and just came as an uncoated surface. I am only deducting 1 star for the coated surfaces, because I can at least flip it over to the uncoated surface and everything is working great.
As a final note, I have not tried this surface with anything other than PLA. Maybe it is possible that other plastics (PETG, ABS?) might stick better to the coated surface.... but I am kinda doubting it.
I've read mixed reviews, so your experience may differ. I am running a stock (mostly) Ender 3. I burned up the stock print surface being stupid. I needed a new surface and ordered this one, not paying attention to what I was ordering.
Initially I was annoyed, but gave it a shot anyway. I had to find some Small binder clips, as the mini's that shipped with the Ender 3 are too small for the glass bed.
I was skeptical that my Ezabl pro sensor from th3d could see the bed, but it worked great after I recalibrated everything.
My first print was fantastic. Bed was set at 60C. The skirt looked great and really adhered great. The part I printed was solid on the bed. I tried to pull it off when it was done and it was stuck REAL good. Then I remembered reading that I needed to let the bed cool down. One the bed cooled, the part came loose with very little effort.
A good dozen or more prints in, and I'm still loving this surface. Every part sticks like mad at operating temperature and comes off easily at room temperature. There are no signs of the coating coming off or wearing. Time will tell.
