SUNLU FilaDryer E2, Professional Drying and Annealing, Up to 110℃/230°F, Born for Engineering 3D Printing Filaments

What is Annealing & Why is it Necessary? Plastic products are placed in a heated liquid medium or hot air circulation box at a constant temperature for a period of time, and then slowly cooled to room temperature, using heat to accelerate the relaxation of macromolecules in the plastic, thus eliminating or reducing the residual stresses in the products after molding. Eliminate the local stress concentration phenomenon produced by different cooling speeds during the cooling and curing process of plastic products. That's what the FilaDryer E2 delivers — a professional-grade 2-in-1 annealing and drying solution specifically designed for Engineering Materials. How to Anneal? Select the Temperature: Determine the right temperature based on the material. Control Heating Rate: Ensure the part is evenly heated. Maintain a Constant Temperature: Adjust the duration according to the size and material. M
