Features: Wide Range Of Applications: these 3D printer glue sticks can be more easily removed from 3D models, and also suitable for project crafts, school projects, art crafts, etc. Compatibility: Suit all 3D printer heating beds, including PEI board, carbon crystal , aluminum and board, etc. Safe: Made of high-quality PVP material, non-toxic, acid free, and will not harm human body. High viscosity formula, which has good adhesion to hot plate or hot bed, easy to remove printing model, and suitable for the first layer before printing. Durable: One glue stick can print more than 100 times continuously, which is practical and helps the 3D printing parts adhere to the building board during the printing process. Easy to Use & Clean: Because it is water soluble raw material, after printing, the platform can be cooled and cleaned with water. Before use, it is recommended to heat the hot bed first, and then apply the glue stick evenly on the platform. After use, cover the lid well to avoid the glue stick drying.
