Normally ABS won't adhere well enough to glass to make this work, but I've found that if I first paint the glass with a thin layer of ABS dissolved in acetone (about 2 parts acetone for 1 part ABS) I get really good results.The model adheres very well to the prepared surface while printing, but pops off easily and cleanly once done.
- Easier to remove the model than from Kapton, but still excellent adhesion while printing. To remove the model, just slide a knife blade under the model and it will pop right off. No need to worry about damaging the surface.
- Easier cleanup than either Kapton or perfboard: just scrape the glass with a blade, and paint more of the ABS/acetone on for the next print
- Glass surface won't bend or warp like the perfboard
Let me know what you think of this technique.
