Carborundum Glass Documentation

The Creality Carborundum glass bed offers a unique printing surface that combines the flatness of tempered glass with a specialised micro porous coating . This silicon carbide-infused surface provides excellent adhesion when heated, typically between 50-70°C for PLA and 70-100°C for PETG/ABS, and automatically releases prints as the bed cools below 40°C without requiring scrapers or adhesives . This guide covers proper installation with binder clips, essential cleaning practices (using isopropyl alcohol between prints and occasional dish soap washing), material-specific temperature recommendations, and troubleshooting common issues like the "welded" effect that occurs with an impeccably clean surface .

• Keep the bed clean, any dust, oil and grease can accumulate over time and will cause print to not stick on the bed. 
  • To clean the bed, you can use Isopropyl/methylated alcohol or acetone  with a paper towel/micro fiber cloth.
  • you can wash under warm soppy water and dry and clean off with isopropyl/methylated or alcohol.
• Printing PLA set the bed to 60-65°C , if you have warping in corners you could consider glue stick or bed adhesive like Magigoo or enable brims or ear/corner brim in the slicers.
• Printing PETG on Glass (80-90°C) is possible but will require a layer such as glue stick, hairspray, Magigoo, Dimafix bed adhesive. 
• Reduce first layer printing speed(10-20mm/s) and for smaller object brim may be required or for larger print ear/corner brim is recommended.
• Wait for the bed to cool before removing the print.
