- Are you tired of scratches on your Kapton tape, or the bubbles that show up when trying to remove your parts?
- Are you fed up with having to change your tape after every 3-4 builds to get optimum results?
- Are you having trouble with your parts warping and delaminating?
- Do you want a reliable 3D printing build platform which is durable and low maintenance?
I was inspired by the work of others who have tried printing on sheets of glass and mirrors, yet at the same time I wanted to have a flexible platform that I could bend to release the parts (like NinjaPlate from adafruit). Gorilla Glass from Corning looked like the perfect candidate. After searching for thin sheets of the stuff that I could cleave down to size for my MakerBot 2X, I realized the iPad screen is the closest thing and fits all the requirements:
- Thin, yet flexible tempered glass
- Scratch-proof (well, scratch-resistant, but the only thing I found to scratch it was diamond or tungsten carbide tip scribers)
- Great thermal conductivity (for uniform heat distribution)
- Very low thermal expansion/distortion (at the usual printing temperatures of 110-120C)
- Resistant to pretty much all solvents I could find (Acetone safe)
- Pretty cheap (bought mine for $15 on Amazon)
- Not too hard to hack it into a build plate (see instructions)
Step 1: What you need
- Generic replacement iPad screen (I got mine for $15 on Amazon)
- Single sided razor blades (or a sharp flexible scraper)
- Acetone and IPA (rubbing alcohol will also do)
- Lint-free cloth (TexWipe works great)
- Binder clips of the right size depending on your hotplate thickness
- Disposable gloves and eye protection
