Questions tagged [glass-bed]

Use this tag for questions related to glass slates used as build plate platform.

Glass or mirror beds are common to be used as print surface and offer the benefit of a very smooth surface, easy cleanability, and removability. After cool down, removing a print from them can be as easy as putting them in a fridge for a couple of minutes. Their downsides are that they are rather brittle and need a higher temperature because of the insulating properties of glass.

Clamps / clips for glass on heatbed

I'm looking for clamps to fix the glass on my heatbed. After some search I found that some people use clamps printed of PLA. Can I use PLA clamps for a heated heatbed (~60 °C)? I also tried foldback clips but they block my nozzle. The Anet A8…

Expansion in bottom skin after first layer

I'm having an issue where prints with narrow tolerance come out fused. This makes it pretty much impossible to print anything with narrow parts. It seems to be mostly (maybe only) an issue in the bottom skin layers. Once it gets through those, the…

I have printed a MPCNC machine. It has a print area of about 30" x 30" and up to 11" tall. (yes, those numbers are correct). I found a perfect piece of glass at a garage sale for $5.00 to use as my print bed. My problem now is how to heat the…

Will a glass bed warp as it is heated?

I purchased a glass bed to use with my still-in-transit Ender 3. Since the bed came in before the printer, I pulled it out and used a flat edge ruler to see how flat the glass surface is. It appears the glass is slightly "dished" in the center from…

I have a 15x15 cm heating resistor from my current printer (printing area: 12x12 cm). I would like to switch to a glass bed and to rework my printer to increase the printing area to 20 cm (22x22 cm glass plate). Would it be possible to use the old…

How do I remove a 3D print stuck to the glass build plate

I printed a model and now I can't remove it. I have been chiselling away with a putty knife and made little or no progress. I even heated the bed up to 70 °C. That really didn't seem to help. Last time, I put it in vice, and tried to free it that…

Why does a raft adhere to the bed while skirt does not?

I'm experimenting with my new Ender 3 V2 using PETG filament on the textured side of the included glass bed without any additional adhesives. I'm been having trouble with adhesion until I found out that enabling raft on my prints helps solve the…

How can I correct *second and third layer* elephant foot?

I'm attempting to print this print-in-place bag clip (in the 80 and 100 sizes). Early prints came out well, except that my persistent elephant foot resulted in locking the hinge. Oddly, a few days ago I printed four simultaneous copies of this…

What can cause the center of the bed to be higher than the sides?

I find it impossible to level the printer recently. I read a couple of articles on bed warping but that refers to having the center of bed lower than the sides (collapsing on its own weight warm up after warm?) but what I experience is the opposite:…

What can cause Z height loss in the first few layers?

All my prints come out about 1 mm too short in the Z dimension. So for example a 20 mm cube comes out 19 mm high. A 10 mm cube comes out 9 mm high. The X and Y dimensions are fine. There's a little bit of visible elephant's foot at the bottom, so I…

Why could my opaque PETG be printing "transparent" in certain places?

I'm printing with opaque grey PETG on glass. The intention is to produce a house number plate, so a shiny, production quality finish on the bottom. For this reason, extruding at 245 °C with a bed at 95 °C, to give a perfect glass finish with no…

Setting up UBL for the first time on Marlin 2.x on a Prusa i3, how often should I level the bed using G29?

I used to use the Marlin 1.x software that would level the bed by probing the 4 corners of my print bed (a long time ago, it's been at least 2 years since I used my printer, wasn't able to set it up after I moved). My slicer had G-code that would…
