We strongly recommend not printing directly on the glass plate without glue, especially for large-area parts.
The adhesion will be extremely strong, and it may easily damage the glass plate.
¶ 1. Spray glue before every print
¶ 1.1 The glue gives the right adhesion and greatly reduces the risk of damaging the glass plate
On large flat prints, adhesive spray is not optional. It does two jobs at the same time.
- It holds the first layer down: a large first layer tends to lift at the edges, and the spray holds it down evenly.
- It keeps the print from bonding too hard: the spray creates a release layer, a thin film between the glass and the printed part, and protects the build plate.
Make it a habit to spray glue before every print. It keeps your print quality high.
¶ 1.2 How to apply it
Please follow this guide: Spray Adhesion
¶ 2. Spray alcohol before you pry
Do not go straight to the spatula. Alcohol or IPA softens the printed part at the contact layer.

- Let the print cool down to room temperature. A hot print grips harder.
- Spray alcohol along the edge, into the gap between the print and the plate.
¶ 3. Removal skills
Three details decide whether the scraper lifts the print or digs into the glass.
¶ 3.1 Wait one minute for the alcohol (or IPA) to soak in
¶ 3.2 Find the loose spot along the edge
Do not force the part where it is still stuck tightly. Re-spray some alcohol, wait a moment, then try to pry again.
¶ 3.3 Pay attention to the scraper angle
- Place the curved side down and the flat side up.
- Keep the blade as parallel to the glass plate as possible.
