The Role of Adhesives in FDM 3D Printing: Your Key to Perfect Prints
In material extrusion 3D printing, ensuring proper first-layer adhesion to the build plate is paramount for success, especially in large-format prints. A well-adhered print guarantees precise model execution and eliminates warping. To achieve this, specialized adhesives tailored to the specific filament type are used.
Why is Adhesion So Important?
Good adhesion is crucial, especially when printing large parts or models with complex geometries. If the first layer doesn’t adhere correctly, the print may be ruined or deformed, potentially damaging the print head.
Many modern printers feature PEI build plates, eliminating the need for adhesives. However, glass build plates, while providing a smooth surface, require additional adhesive preparations.
Choosing the Right Adhesive for Your Filament:
Different 3D printing materials require specific adhesives for optimal results. Here’s a quick guide to popular filaments and their recommended adhesives:
Filament | Build Plate Temperature | Recommended Adhesives |
PLA | 0-60°C | Dimafix, Asnare, PVP |
ABS* | 100°C | Dimafix, Asnare |
PET-G | 70-80°C | Dimafix, Asnare, PVP |
TPU-93A | 40-70°C | Dimafix, Asnare |
PA* | 90-110°C | Magigoo PRO PA |
PA Composites* (e.g., GF30-PA6, CF PA-12) | 90-110°C | Magigoo PRO PA, Asnare |
PP* | 0/100°C (varies by adhesive) | PP Tape (0°C), Magigoo PRO PP (100°C) |
PC* | 90-110°C | Magigoo PRO PC, Asnare |
Engineering Materials* (e.g., PEI, PEKK, PEEK) | 100-250°C | Vision Miner Nano Polymer Adhesive |
*Recommended printing with a heated chamber.
How to Apply Adhesives:
Applying adhesives is simple but requires precision. Follow these steps:
Clean the build plate surface from dust, grease, and previous print residue.
Apply a thin, even layer of the appropriate adhesive to the build plate.
Preheat the build plate to the recommended temperature before printing (see table above).
For high-temperature Vision Miner Nano Polymer Adhesive, preheat the build plate to 100℃ before applying with a special brush. Exercise caution to avoid burns and consider wearing a mask.
