The best and most useable surface ?

Recommended Posts

I've been using Scotch blue tape for a while. It works well is acceptable to apply and remove.

However it's not a perfect clean surface, it's a bit rough and sometimes blue color leaks into the print bottom.

I've been trying only glass but it's kinda a mess with the glue stick and it does not bond that well.

I've tried Kapton tape but using it was horrible. It's barely possible at all to put it on the glass without loads of bubbles and it gets damaged easily.

I wonder, what's the best to use ? Considering I mostly print on ABS.

Not too many people talk about hair spray, but I have found it to be great on heated window glass. Good enough that because I tried it first, I have had no inclination to try ABS slurry or glue sticks. Just lightly spray a clean piece of glass, allow to dry, and heat to ~70c for PLA or ~100C for ABS. Parts release when the glass cools. Its simple. I don't understand why more people aren't using it.

Glass is the latest innovation and is better than kapton tape or blue tape.

hair spray, glue stick, wood glue all have PVA in them. For hair spray use a tissue - spray that and then wipe it on with the tissue. This keeps PVA out of the rest of your printer.

Wood glue mixed with 10 parts water (doesn't have to be exact - it all dries away anyway) is the easiest - mix in a small jar and shake well. Use a paint brush to apply. Let it dry (dries faster with heated bed on). You can reuse this surface for many prints. You can add only a tablespoon of water and spread it around again or you can completely wash the glass and start over. Wash the glass once per month to remove dust and finger oils. Even if you only use the printer once per month.

I'm guessing your main problem is not glue related but you aren't squishing the bottom layer into the glass enough - you probably still have it leveled to the old tape height. Instead of running the stupid leveling procedure - just turn the 3 leveling screws CCW a half turn and when the print starts make sure the lines are pressed into the glass a bit.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
