Optimized printing quality, high purity with low shrinkage and superb layer bonding, meeting your demands for printing projects of functional parts with higher toughness. FAQs: Why can't the filaments stick to the build bed? 1. Check the temperature setting before printing, PLA filaments have lower extrusion temperature; 2. Check if the plate surface has been used for a longtime, it is recommended to replace it with our new one to ensure an strong first layer adhesion ; 3. If the first layer has poor adhesion, it is recommended to re-level the print substrate to reduce the distance between the nozzle and the surface plate; 4. If the effect is not good, it is recommended to try printing the draft before printing.
